摘要： A bending meshing type gear device includes a wave generator, an external gear which is bent and deformed by the wave generator, and internal gears which meshes with the external gear. One of the external gear and the internal gears is formed of a resin, and the other of the external gear and the internal gears is formed of a high thermal conductivity material having thermal conductivity higher than that of the resin. The gear device further include an abutment member which is connected to the internal gear and abuts the external gear, the internal gear is formed of the resin, the external gear is formed of the high thermal conductivity material, and the abutment member is formed of a high thermal conductivity material having thermal conductivity higher than that of the resin.

摘要： The life estimation system is a life estimation system that estimates a life of the reduction gear including a reduction mechanism. The life estimation system includes a sensor that is to be mounted onto the reduction gear and detects information for identifying a stress generated in a specific part of the reduction gear, and an estimating unit that identifies the stress generated in the specific part based on detection information obtained by the sensor and estimates the life of the specific part based on the identified stress.
