[0002] A centerless grinder is a machine tool used for grinding cylindrical workpieces and has a wide range of applications in industrial production. When grinding with a centerless grinder, the workpiece is not supported on the centers or clamped in the chuck, but is placed between the grinding wheel and the regulating wheel, supported by the supporting plate and the regulating wheel. The grinding wheel plays a grinding role, and the regulating wheel controls the rotation speed and feed rate of the workpiece.

[0003] Currently, the transmission parts in a centerless grinder cooperate with each other to jointly ensure that the centerless grinder can perform grinding operations stably and efficiently.
