Abstract
The utility model provides an internal spline belt pulley, comprising a pulley, a bearing, a shaft sleeve, a handle and a bolt, wherein a step hole is arranged at the end face of the pulley; the bearing is sleeved inside the step hole; the shaft sleeve is sleeved inside an inner hole of the bearing; the bolt passes through an inner hole of the shaft sleeve and then is connected with the handle; a first annular groove is arranged at the inner wall of the step hole; a jump ring capable of preventing the bearing from axially sliding is arranged inside the first annular groove; a second annular groove is also arranged at the inner wall of the step hole; and a dustproof cover is arranged inside the second annular groove. The internal spline belt pulley provided by the utility model is simple in structure; the dustproof cover and a sealing ring are added; the dust in the working environment is prevented from entering inside the bearing; a baffle plate is also arranged at the joint of the handle, so as to a play a dustproof role; a dustproof design is achieved at the two end faces of the bearing; and the internal spline belt pulley has good dustproof effect. Thus, the service life of the bearing can be prolonged; and the stability of the device is also improved.
