Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-2, the cast iron belt pulley detacher includes a motor 1, an output shaft of the motor 1 is fixedly connected with a transmission shaft 2, a gasket 5 is sleeved on an outer side of the transmission shaft 2, an inner ring diameter of the gasket 5 is slightly larger than a diameter of the transmission shaft 2, an outer ring diameter of the gasket 5 is slightly larger than a diameter of a belt pulley body 4, the gasket 5 is composed of two half rings, the belt pulley body 4 is movably installed on an outer side of the transmission shaft 2, a puller assembly 3 is movably installed on an outer side of the gasket 5, the puller assembly 3 includes a fixing plate 303, a screw 304 is movably connected inside the fixing plate 303, a rotating ring is fixedly connected to the bottom of the screw 304, a movable block 302 is connected to an outer side of the screw 304 in a threaded manner, a threaded through hole is formed inside the movable block 302, the threaded through hole is connected with the screw 304, fixed blocks 305 are fixedly connected to left and right sides of the movable block 302, a puller claw 301 is movably installed on top of the two fixed blocks 305, a slider is fixedly connected to the bottom of the puller claw 301, and a sliding chute matched with a size of the slider is formed on top of the fixed block 305.
