Abstract
A powder supply mechanism, which is provided with a press-molded article obtained by consolidating a solid lubricant powder in advance, is incorporated into an inner-side space of an externally toothed gear of a strain wave gearing. While the strain wave gearing is operating, the press-molded article is worn down by the friction plate, whereby the powder supply mechanism can incrementally supply very small amounts of a solid lubricant abrasion powder from the press-molded article over an extended period. It is possible to suppress any reduction in efficiency caused by loss torque produced due to a large amount of the solid lubricant powder infiltrating gaps in, inter alia, a contact section of a wave generator rotating at high speed. Thus, it is possible to extend the service life of the powder-lubricated strain wave gearing while keeping the efficiency consistently high.
