ROLLING TYPE SUPPORT STRUCTURE AND TRANSMISSION DEVICE

摘要

A rolling type support structure and a transmission device. The rolling type support structure comprises a shaft body (10), wherein the shaft body comprises an upper support part (11) and a lower support part (12) which play a lateral support role. The periphery of the lower support part is provided with a rolling piece (61), and an upper end or a lower end of the shaft body is connected to a lateral support piece. By adopting a rolling type structure of a sleeve or a needle bush, the support structure greatly reduces the frictional force between same and a rail in the process of using, eliminates the rail shake phenomenon, increases the service life of the rail and enables the operation of a transmission device to be more stable.
