Abstract
Disclosed is a power-transmitting apparatus The power-transmitting apparatus of the present invention comprises: a pin gear provided with a plurality of pins capable of rolling movement; a spur gear provided with a plurality of teeth and engagingly coupled to the pin gear so as to be relatively movable; and a lubricant supplying unit provided on the pin gear to supply lubricant to the plurality of pins. According to the present invention, by regularly applying a lubricant, the occurrence of problems such as the adherence of external dust and the efflorescence of the lubricant can be reduced, and in particular, because lubricant can be self-supplied to the plurality of pins provided on the pin gear, as opposed to the prior art, the task of applying a lubricant can be easily performed.
