Background

A bearing is a widely used component of a machine, and is typically mounted on a shaft in an interference fit. When a part of the bearing is installed, the inner diameter of the bearing is increased and then the bearing is installed on the shaft, the inner ring is contracted and clamped on the shaft after being cooled, but when the bearing is damaged or broken, the bearing is more troublesome to detach, because the bearing is not convenient to heat, the bearing is taken down from the shaft by direct beating, the bearing is not easy to detach in a time-consuming and labor-consuming manner, the rotating shaft is easy to damage in the beating process, the rotating shaft with smaller diameter is easy to bend, and particularly, large-sized parts such as a roller and a speed reducer are more difficult to detach.

For example, in a quick-detachable bearing ejection device provided by CN212978167U, the screw rod that uses screw feeding drives the ejection end to advance, so as to eject the transmission shaft in the bearing, but installing the ejection device requires additional equipment and installation space, which increases complexity and cost of the system, and meanwhile, when the application faces a large-sized rotating shaft, the application is difficult to eject the large-sized rotating shaft, and is not suitable for large-sized parts, and the application range is limited.
