Description

A mirror plate grinding device with adjustable revolution diameter

technical field

The invention relates to the technical field of mirror plate processing, in particular to a mirror plate grinding device with adjustable revolution diameter.

Background technique

The mirror plate of the hydroelectric generator set is generally made of No. 45 forged steel, and its function is to transmit the thrust load to the thrust pad, which is a very critical part of the thrust bearing. With the wide application of elastic metal-plastic thrust tiles, it has stricter requirements on the surface finish of the mirror plate. If the mirror surface finish is insufficient, flocculent slurry will be worn out on the tile surface during the cranking process of the unit, that is, the tile surface will be severely worn. Therefore, the quality of the mirror plate finish will directly affect the safe and stable operation of the thrust bearing and even the hydroelectric generator set. Therefore, during the overhaul process of the hydropower unit, the surface of the mirror plate must be ground to ensure the surface finish of the mirror plate. Meet the requirements.

However, due to the inconsistency of the size of the mirror plates of different existing units, if a grinding device is designed and manufactured according to the mirror plates of different diameters to adapt to the mirror plates of different diameters, the production cost will become higher. If only one grinding device is used When grinding mirror plates with different diameters, when the size of the mirror plate is larger than the grinding range of the grinding device, the entire surface of the mirror plate cannot be covered, resulting in that the surface of the mirror plate cannot be completely ground.
