摘要： PROBLEM TO BE SOLVED: To provide a simply formed rotation transmission mechanism by engagement capable of maintaining the reduction effect of tooth hitting noise caused between engaged surfaces for a long period by using a grease mixed with a powder.
SOLUTION: This rotation transmission mechanism comprises a drive member and a driven member for transmitting a rotation by the engagement. Both engaged surfaces are coated with a lubricating grease. A powder formed of an elastic material is mixed in the lubricating grease. A large number of fine recesses into which the powder is allowed to intrude are formed in the engaged surfaces of the drive member or the driven member.

摘要： PROBLEM TO BE SOLVED: To improve power transmitting performance with a reduction in the operating torque and the torque fluctuation of a gear. SOLUTION: The surface roughness of a driven gear (a worm wheel 12) is set to be in a plateau condition (a flat mountain and a deep valley) with a skewness Rsk of 0.8 or less, as shown in Fig.(a). Preferably, a center line average roughness Ra of the driven gear (the worm wheel 12) is set to be 0.9 μm or less. Thus, a valley portion having a deep tooth face serves as an oil reservoir to improve lubricating performance, resulting in a reduction in the operating torque. A mountain portion having a flat tooth surface moderates the contact bearing pressure of the gear, resulting in a reduction in the operating torque. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：通过减少齿轮的工作扭矩和扭矩波动来提高动力传递性能。解决方案：如图所示，从动齿轮（蜗轮12）的表面粗糙度被设定为具有0.8或更小的偏斜度Rsk的平稳状态（平坦的山脉和深谷）一个）。优选地，从动齿轮（蜗轮12）的中心线平均粗糙度Ra设定为0.9μm以下。因此，具有深齿面的谷部用作储油器以提高润滑性能，导致操作扭矩的降低。具有平坦的齿面的山部缓和齿轮的接触轴承压力，导致操作转矩的降低。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a planetary gear device having an excellent lubricity and a high grease holding effect.
SOLUTION: A planetary gear is structured by laminating a plurality of thin plates 27 press-formed in a same form and rotatably supported by a gear pin 13 provided through a center hole 28 formed at a center part of each thin plate 27. In the planetary gear, a grease receiver 29 is formed by utilizing sagging generated when pressing at an inner circumference corner part of the center hole 28 of each of the thin plates 27. In other words, a clearance formed between the sagging at each of the thin plates 27 and the gear pin 13 is formed as the grease receiver 29. Thus, lubricity of the planetary gear is improved, grease can be prevented from scattering at the time of rotation of the planetary gear and it is possible to secure excellent lubricity for a long period of time.
