    摘要: A strain wave gearing (1) has contact parts (B, C) which are the portions to be lubricated other than the teeth of an externally toothed gear (3) and an internally toothed gear (2), the contact parts being respectively lubricated with an inorganic lubricating powder having a lamellar crystal structure. The lubricating powder, during the operation of the strain wave gearing (1), is crushed between the contact surfaces of each of the contact parts (B, C) to move and adhere to the contact surfaces, thereby forming thin surface films thereon. Additionally, the powder is thinly spread by pressure and reduced into finer particles to change into a shape which facilitates intrusion into the space between the contact surfaces. By both the fine particles having changed in shape and the surface films, the lubrication of the contact parts is maintained. Neither the fine particles nor the surface films are viscous. Compared to the case where a grease or an oil is used as a lubricant, the efficiency in the low-load region and the high-speed region can be greatly improved.
