Abstract

The present invention relates to an auxiliary starting device for heavy-duty roll grinder. It includes main driving final-stage large belt pulley, It is characterized by that it also includes starting motor, a group of worm and wormwheel, two pairs of stud gears and rocker control mechanism. Said invention also provides their connection mode and the working principle of said auxiliary starting device.

Description

technical field [0001] The invention relates to a heavy-duty roll grinder in the field of mechanical processing, in particular to an auxiliary starting device for the heavy-duty grinder. Background technique [0002] In the grinding machine used in the heavy roll processing industry in the prior art, the workpiece to be processed is started by the headstock. During the grinding process of the grinding machine, in order to ensure the high standard of the surface accuracy of the workpiece, it is necessary to ensure that the workpiece starts smoothly. Therefore, the V-belt drive is adopted for the drive of the head frame to reduce the vibration generated by the rigid drive of the gear and improve the grinding accuracy. However, when the heavy grinder is started, it is difficult to start because of its large static friction and moment of inertia. Usually, the start is achieved by increasing the diameter of the starting pulley, increasing the number of belts, and increasing the...
