  • Deterioration of the Lubricant for Hydrodynamic Grooved Bearing:—A Difference of Simple Heat Deterioration of the Lubricant and the Deterioration by Consecutive Driving in the Bearing—

    OHNO Hideaki, MATSUMOTO Susumu

    Journal of the Japan Society for Precision Engineering   79 ( 6 ) 523 - 528  2013

    　View Summary

    Hydrodynamic grooved bearings are widely used in the HDD(Hard Disk Drive) mechanism for rotary precision, noise reduction, and superior shock-resistance. Therefore, many studies have been made, but most of them have dealt with the bearing design or vibration analysis. This report studies the viscosity increase of the lubricant that affects the life of the hydrodynamic grooved bearing, which compares the viscosity increase in the continuous driving test in the bearing with that in the accelerated high temperature test. The viscosity increase of the lubricant in the accelerated high temperature test is bigger than that in the continuous driving test in the bearing. Both tests generate the same materials. So, Marangoni effect causes the smaller viscosity increase of the lubricant in the continuous driving test in the bearing. The temperature gradient in the bearing causes the low evaporate materials with high viscosity to move to the gas-liquid boundary, which prevents the low viscous material from evaporating, resulting in the smaller viscosity increase. Therefore, the life of the lubricant in the bearing is longer than what is expected by Arrhenius equation in the accelerated high temperature test.

    　View Summary

    Machine designers are sometimes confronted with high contact pressure conditions which generate plastic deformation. However there is no clear design method for such severe condition. We investigate the contact condition in the high contact pressure by using a ball-on-glass disc type test. According to the test results, the following conclusions were obtained. <br>1) The ratio of calculating contact pressure and the hardness in consideration of working hardness, the number of the ratio is settled about 0.4 for any loading condition.<br> 2) In the condition of high contact pressure generating plastic deformation, the contact pressure converges with constant value according to the work hardening behavior of material.

    　View Summary

    Traction drive makes oil film between two rollers, and power is transmitted by oil film shearing. It has the following characteristics. (1) Traction drive can be operated at low level of vibration and noise, so the), are more suitable at higher speed rotations than gear (2) Traction drive can change continuously the distance from the contact point of the rotating part to the axis of rotation; it is useful in continuously variable transmission (CVT). Generally-fixed-reduction-ratio-type traction drive is developed for the purpose of use by high-speed rotation taking advantage of the feature of characteristic (1). On the other hand, the authors have developed a micro drive system for transmission; a microtraction-drive based on the structure of an angular ball hearing is advantageous over geared speed reducers, for small scale equipment requiring high numbers of revolutions. A micro-traction-drive is easily manufactured by modifying angular bearings and tapered roller bearings for which preload inner race and outer race act as thrust force. The driving force is transmitted by the contact of the retainer with the rolling element in the rotating direction. The test of the experimental model of micro-traction-drive using an angular ball bearing of 10 nun inner diameter 30 mm outer diameter and 9 mm width was carried out. Power-absorbing-type test equipment was made and the input and output torque, number of revolutions, temperature, noise, and state of lubrication were measured. With the same test equipment, the micro-traction-drive was compared to the equivalent type planetary gear with outer diameter of 32 mm on the market. In comparison with commercially, available speed reducers, the planetary gear system, the new v developed micro-traction was found to bear superior performance in terms of allowable transmission torque, efficiency, noise, and other characteristics.

    　View Summary

    Micro traction drive is a transmission by using of modified ball bearing. The traction force is generated by the thrust pre-load between inner race and outer race. The driving force is transmitted by using of retainer that is connected to output shaft. Test-drives of micro traction drive have been carried out as single stage type (reduction ratio around 2.0) and as tandem stage type (reduction ratio 7.3). The dimension of the micro traction drive is 10mm inner diameter, and 30mm outer diameter. As a result of the test, we have found that single stage type traction drive can transmit higher torque, higher number of revolution with lower noise and vibration than planetary gear head. Tandem type traction drive has been successfully operated at maximum speed 20000rpm.

    　View Summary

    This paper discusses about the new vibration model of gear pair in consideration of oil film force in order to evaluate the dynamic load in steady meshing and the impact load in tooth flank separation with sufficient accuracy. This new vibration model is constituted by combining an oil film model and a spring and damping model in series. In the oil film model, the force produced according to the wedge and the squeeze effect of an oil film between meshing teeth was modeled. Moreover, it was also taken into consideration that viscosity changes with oil film pressure. A spring and damping model represent the force generated by bending of a tooth, and fluctuation of stiffness accompanying change of number of meshing teeth and meshing position was taken into consideration. This model was applied to a pair of gears on which fixed torque acts and the camshaft drive gear which tooth flank separation generates by fluctuation torque. And comparison of a calculation result and an experimental result was performed to tooth root stress. The calculation results and the experimental results showed the good coincidence, and it was clarified that the model was appropriate.

    　View Summary

    This paper discusses the nonlinear characteristics of the gear coupling derived by tooth contact analysis and the verification test of the analysis method. Tooth contact analysis evaluates the load distribution by solving simultaneous linear inequality derived from compatibility condition of the tooth deformation and balance condition of the force. By applying this method to the gear coupling, we evaluated bending moment and shear force. It was found that nonlinearity of stiffness and damping occurred by the change of contact region of all teeth by load torque or alignment. Rotor dynamics coefficient of the gear coupling was clarified, and it was enabled that the nonlinearity of the gear coupling could be considered for the design of rotating machinery. Next, the tooth stress, bending moment and shear force were measured in the static loading test to verify the analysis method. Analysis results showed the good agreement with the experimental ones, and it was clarified that the analysis method was appropriate.

    This paper presents experimental study and numerical simulation of vibration and noise of a speed increaser, which consist of a star type planetary gears and a planetary type epicyclic gear train. The ring mode vibration of internal gear in the star type planetary gears and torsional vibration of planetary gear in the planetary type epicyclic gear train are measured by use of telemetry system. The influence of tooth profile error for the vibration and the noise is clarified. The numerical simulation is also carried out to evaluate the exciting force and it's associated vibration. In this method, the coupled vibration of shaft bending, torsinal and ring mode vibration of the internal gear are taken into account employing modal synthesis method. The simulation results shows a good agreement with the experimental ones. And it is found that the ring mode vibration magnifies the higher order component of gear mating frequency.

    Spin on the contact surfaces between two elements occurs in such diverse machine elements as angular contact ball bearings or continuously variable transmissions adapting traction drives. We experimentally and analytically studied the effect of spin on lubricating oil film thickness on angular contact ball and disk. Oil film thickness was measured under different spin angular velocities for constant rolling velocity and different contact loads using optical interference method. We clarified the effect of spin on minimum and central thickness of oil film and film shape and analyzed thermo-elastohydrodynamic lubrication (TEHL) considering spin under experimental conditions.

    The purpose of this study is to investigate the effect on oil film thickness and traction coefficient by the sudden change of loaded torque on traction drives. The experimental measurements of oil film thickness and traction force were performed using the optical interferometic observation method. And the comparison of experimental results with calculations of the two dimensional non-steady thermal elastohydrodynamic lubrication (TEHL) was performed. We obtained that oil film thickness and traction coefficient decrease though the rotating speed of roller and disc increase, and our discussion lead that the reason of the decrease is the effect of the increase of oil film temperature by shear. The consideration of frictional heating improved the accuracy of calculations about oil film thickness and traction coefficient.

    　View Summary

    Currently in industries, high-speed turbo machineries such as compressors and steam or gas turbines are required to have increased power capacities. Due to this, a large gear size is required which leads to nonuniform temperature distribution. As the result of nonuniform temperature distribution, nonuniform thermal distortion occurs. Change in load distribution due to this thermal distortion is considered to be closely related to scoring and pitting failures. In order to ensure reliability of high-speed gear units, it is necessary to improve the following techniques. (1) The method of predicting the temperature rise of gears and thermal distortion. (2) Tooth correction against thermal distortion. In this paper, a three-dimensional model for calculating the temperature of teeth surfaces and blanks is presented. This model includes the effects of convective cooling by lubricating oil and the change in load distribution due to mechanical deformation. The calculated results of gear teeth temperature and bending stress are in reasonable agreement with the experimental results. It is confirmed that the analytical method is practical and useful.

    　View Summary

    In cross head type marine diesel engines, cylinder oil is supplied at regular intervals and constant quantity from oil-feed holes to lubricate the running surface of piston rings and cylinder liner. Accordingly it is important to determine position of oil-feed holes, timing of oil-feed, running surface profile of piston rings and cylinder liner and so on to make cylinder oil spread wider and form thicker oil film. In this study, the authors examined how the factors influence the extension of cylinder oil using the tester which simulated cross head type marine diesel engines for the purpose of utilizing small quantities of cylinder oil effectively. We found that wave-cut surface of cylinder liner has better spreadability of cylinder oil than honed surface and wave-cut surface with oil grooves has the effect of circumferential spreadability especially.

Calculated results of gear teeth temperature and bending stress are reasonably close rimntal results. It is confirmed that the analtical method is practical and useful.

  • The Study on Tribological Characteristic of Traction Drives at Non-Steady Condition (1st Report, Optical Interferometoric Observations of Transient Oil Film)

    TOZAKI Yasuyoshi, HAYASHI Noriyuki, MATSUMOTO Susumu

    Transactions of the Japan Society of Mechanical Engineers. Series C.   65 ( 632 ) 1684 - 1689  1999

    　View Summary

    The purpose of this study is to investigate the effect on oil film thickness and traction coefficient by the sudden chnage of loaded torque on traction drives. The experimental measurements of oil film thickness and traction force were performed using the optical interferometic observation method. And the comparison of experimental results with calculations of the two dimensional non-steady thermal elastohydrodynamic lubrication (TEHL) was performed. We obtained that oil film thickness and traction coefficient decrease though the rotating speed of roller and disc increase, and our discusion lead that the reason of the decrease is the effect of the increase of oil film temperature by shear. The consideration of frictional heating improved the accuracy of calculations about oil film thickness and traction coefficient.

  • 塑性変形進行を考慮した転がり接触面端部のトライボロジー特性評価手法

    2005  

    　View Summary

    １．研究目的　歯車や転がり軸受の転がり接触面に於いて、材料の弾性限界を超えた接触圧力で使用する場合の設計手法を解明する。具体的には塑性変形量および弾性流体潤滑油膜厚さと初期接触圧力、繰返し数の関係を実験的に明らかにする。２．使用した試験機　光干渉式流体潤滑膜観察試験機を用いた。接触面に半透過膜（クロム）を蒸着した硬質ガラスと、直径6.35mmの鋼球（SUS)、黄銅球を純転がり、塑性域接触圧力条件で接触させ、ガラス背面から接触部の干渉縞を観察して、接触領域と油膜厚さを求めた。３．試験結果　下記のことが明らかとなった。　１）転動繰返しによる塑性変形の進行に伴う接触圧力低下の傾向は、初期接触圧力、材料に依らずほぼ一定の傾向となった。　２）塑性変形にともない潤滑油膜も厚くなる方向に改善されて行く。　３）塑性変形の進行は、初期の材料硬度を基準とした弾性接触限界圧力でほぼ０．４（接触圧力／材料ブリネル硬さ)に漸近する。　４）塑性変形の進行は、変形を考慮した接触圧力が材料の弾性接触限界になるまで継続する。すなわち、塑性変形が飽和する繰返し数は、初期接触圧力に依存する。４．考察　従来、数回で飽和（Shakedown)するといわれていた転動面の塑性変形進行は、形状が材料の弾性接触限界になるまで進行する。すなわち、塑性接触域での転動面の使用は、接触繰返しにともなう接触圧力低減線と、転動疲労発生限界線の交点が運転限界になる。５．今後の課題　転動面塑性変形は接触伴うせん断応力が最大になる転動体内部内部の加工硬化、材料硬度上昇を考慮する必要がある。運転繰返しによる加工硬化の状況を明らかにし、初期硬度基準による転動面塑性域接触面設計手法を取りまとめて行く。

  • 微小集中接触域を有する機械要素のトライボロシー設計手法の研究

    2004  

    　View Summary

    1.微小接触域を有する転がり接触面の転動疲労寿命の解明　スラスト玉軸受式転動疲労試験機、4ローラ式転動疲労試験機を用い接触息サイズの影響を実験検討した。その結果、接触面が弾性流体潤滑油膜で分離されない状態(混合潤滑状態)では、点接触（スラスト玉試験）では、接触面の相対曲率半径が0.2ｍｍまで、1.0ｍｍまでは、それより大きな相対曲率半径の場合の転動疲労寿命と変わらないことがわかった。　この理由として、接触面が油膜分離されない場合は、表面起点き裂型の転動疲労になり、疲労寿命が材料の応力体積の大小に左右されないことを考察した。本研究により従来は相対曲率半径10ｍｍ止まりであった実証サイズ域が広がり、微小領域での転動疲労寿命設計の考え方が明らかになった。　今後は、内部起点き裂型である接触面油膜分離状態での転動疲労寿命検証を行い、微小接触域を有する転がり接触面設計法の確立を目指す。（成果発表：３件）２．転がり軸受活用型マイクロトラクションドライブの開発　アンギュラ玉軸受の保持器を遊星キャリアとした新方式のトラクションドライブを考案し、性能確認を行った。試作諸元は、外径30ｍｍ、内径10ｍｍ、玉径4.76ｍｍ、玉数9個、接触角15degで、キャリアを出力としたスター型遊星方式で、最大伝達トルク8Ｎｍを達成し、同サイズの遊星歯車装置（並行実験確認4.5Ｎｍ）を上回る性能が確認できた。　なお本開発トラクションドライブは、(財)メカトロニクス技術高度化財団および三菱重工業(株）の共同研究として、小型飛翔ロボット用として、キャリア固定の二重反転変速装置への適用を進めるベース技術となった。（成果発表：２件)３．微小接触を有するトライボロジー要素の設計手法の改善研究　動力伝達歯車歯面ピッチング(転動疲労）寿命の確立設計手法、および３元アブレシブ摩耗対策としての微小溝効果に関する研究を実施した。(成果発表：２件)

  • 数理的理解に拘束されないマインズアイによる発想の工学的具現化システムの研究

    2004  

    　View Summary

    １．技術開発段階におけるリスクマネジメントと意思決定手法の研究　最終的に人間の経験と勘によって意思決定する技術開発実行可否問題を、定量的に簡易評価するプログラムを作成した。汎用性を考慮し、Excel(エクセル)を用いたソフトをとりまとめた。試運用として中国における家庭用エアコンを対象にし、中国における300例のニーズアンケート調査とその分析、それを踏まえた試計算を行い、実用できることを確認した。（成果発表：1件)２．マインズアイからの発想の具現化検討　子供用３輪車サイズ（前後輪間隔60ｃｍ以内、２輪間隔50ｃｍ以内)で、大人が使える３輪車を松本研究室修士1年(6名)で発想し、従来にない３輪車を設計、制作した。発表は福岡県遠賀町の三輪車4時間耐久レースに参加することで行った。マスコミ(毎日新聞）が、早稲田大学のアクションとして採り上げ、準備段階とレース結果の２度にわたり、取組状況を記事にした。　アイデア発想は、6名修士学生のマインズアイからの発想を図面にし、相互情報交換を3回行い、試作アイデアに収束させた。その結果、当初全く予想していなかった形態が生まれ、この手順をシステムとして行くことも具現化の方策になることがわかった。（成果発表(取材）：２件）３．松本零士のマインズアイの研究　松本零士の著作を精読し、科学技術的な発想のプロセスを分析した。その結果、発想の原点は、本人の経験と情報蓄積にあることがあり、個人の中に蓄積した膨大な情報を組み合わせてオリジナルな発想へ転換し、絵画として具現化している。特に本人の記憶力に依存するが、幼児から少年時代の蓄積が失われていない。これは、少年時代の体験やアイデアを繰り返すことにより、より強力な個人情報としてマインズアイの力になっていると分析された。経験情報を画像にしてゆくプロセスを今後の課題にしてゆく。なお、少年時代の各種興味と経験がより大きな発想を生み出す駆動力となることが判ったので、松本零士氏の勧めもあり、北九州に早稲田大学を拠点とする宇宙少年団を立上げ、分団長として少年の科学技術啓蒙活動を展開することになった。(成果発表(取材)：1件)
