[0024] The present invention is a metal rubber flexible spoke gear, such as figure 1 , 2, it specifically includes: a ring gear 1, a retaining ring 2, a hub 3, a key 4, and a metal rubber block 5, etc. The ring gear 1 is uniformly punched with rectangular through holes along the inner diameter of the ring; The ring 1 has a separate design, with a keyway at the position corresponding to the through hole of the ring gear; the key 4 is matched with the keyway of the hub 3, and is connected with the hub 3 by the hexagon socket head screw 7; metal rubber The block 5 is embedded in the gap formed by the hub, the key and the ring gear. In the normal operation of the gear, the metal rubber will be squeezed when the hub and the ring gear rotate relative to each other. Because the metal rubber has certain elasticity and good damping characteristics, the above design can realize the vibration reduction and isolation of the metal rubber flexible spoke gear characteristic. At the same time, be...
