Transmission mechanism of gear rolling machine

The invention discloses a transmission mechanism of a gear rolling machine. The transmission mechanism comprises an outer bush, a deep groove ball bearing and an inner bush, wherein the outer bush is fixed on a rolling machine tool in a sleeved mode, the deep groove ball bearing is arranged inside an inner hole of the outer bush, the inner bush is installed inside an inner hole of the deep groove ball bearing, and the outer diameter of the deep groove ball bearing is 280mm, and the inner diameter of the deep groove ball bearing is 180mm. The transmission mechanism has the beneficial effects that the structure of the transmission mechanism is improved by selecting the deep groove ball bearing with proper model, the inner diameter of the outer bush and the outer diameter of the inner bush are increased, so that the transmission mechanism is suitable for processing a synchronizer gear sleeve with larger size, and can be used for solving the problem of small processing range of a gear rolling machine in the prior
