[0002] The roll grinder includes a bed, headstock, tailstock, bracket and other mechanisms. The headstock and tailstock are arranged at the front and back of the bed respectively, and two brackets are arranged in the middle of the bed. The brackets are bent into an L shape. After the roll workpiece is hoisted to the grinder, the headstock, tailstock and bracket jointly support the roll. The headstock is used to drive the roll to rotate. The tailstock is used to axially position the roll during its rotation to avoid axial movement. The bracket is used to support the roll workpiece and is supported at the roll neck of the roll. Figure 1 As shown in the figure, during the roller rotation process, the roller surface is processed by the grinding system.

The roll neck of the roll is supported by the support shoe, and the support shoe is in direct contact with the roll neck. Direct contact will cause the following problems: when the roll rotates, relative movement will occur between the support shoe and the roll neck, which will increase friction, causing not only wear of the support shoe, but also dry friction and heat between the two, reducing the life of the parts. At this time, lubrication is particularly important. Summary of the invention
