CRUSHER BELT TENSIONING APPARATUS

摘要

A crusher belt tensioning apparatus for mounting at a crusher and in particular a mobile crushing unit is provided. The belt tensioning assembly includes a base frame that mounts a moveable swing arm via a plurality of non-rigid mountings to provide vibration and shock absorption during use. A variable belt tension setting is achieved via a linear actuator operating between the swing arm and the base frame to change the relative position of a tension pulley in contact with the drive belt.

1. Crusher belt tensioning apparatus for mounting at a crusher unit having a crusher pulley mounted at a shaft to actuate a crusher forming part of the unit, a drive pulley mounted at a shaft driven by a motor and a belt extending around the crusher pulley and the drive pulley to transfer drive from the motor to the crusher, the apparatus comprising:
a base frame mountable at a chassis frame of the crusher unit; a tension pulley mounted at the base frame to contact and apply a tension force to the belt; a swing arm pivotally mounted at the base frame via a first region of the swing arm, the tension pulley mounted at a second region of the swing arm; and an actuator positioned at the base frame to act between the base frame and the swing arm to control a position of the swing arm and the tension pulley relative to the base frame.
