The invention discloses a belt pulley of a crusher. The belt pulley comprises a belt pulley body and is provided with a conical shaft hole in the middle. The two opposite sides of the inner side of the shaft hole are processed into planes, and the planes of the inner side of the shaft hole are trapezoidal. The belt pulley of the crusher is simple in structure and is convenient to demount and mount by processing the special-shaped shaft hole.
Description
technical field [0001] The invention relates to a crusher pulley. Background technique [0002] Due to the frequent use of mining crushers, the hammer head needs to be replaced frequently. However, when replacing the hammer head, it is necessary to remove the pulley on the crusher. There is an inner hole in the middle of the pulley, and there is a key connection between the inner wheel and the shaft of the crusher, which is tightly fixed. It is very inconvenient to disassemble and assemble. Contents of the invention [0003] The object of the present invention is to provide a crusher pulley aiming at the defects in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solution: a crusher pulley, including the pulley itself, a tapered shaft hole is arranged in the middle of the pulley, and two opposite surfaces inside the shaft hole are processed into planes. [0005] Preferably, the plane inside the shaft hole ...
