Abstract

The invention discloses an improved dual-support oil wedge-shaped dynamic pressure spindle assembly for a conical roller coreless grinding machine. The dual-support oil wedge-shaped dynamic pressure assembly comprises a spindle, a sand wheel combination and tile sleeve combinations; the sand wheel combination is positioned in the middle of the spindle and comprises a sand wheel chuck, a spindle conical sleeve, a sand wheel chuck end cover and a sand wheel; the sand wheel is fixed on the sand wheel chuck by the spindle, the sand wheel chuck, the spindle conical sleeve and the sand wheel chuck end cover; the tile sleeve combinations are arranged at two ends of the spindle; each tile sleeve combination comprises a tile sleeve, a shaft tile, a tile sleeve end cover, a tile sleeve end cover and an end cover connection disc. Compared with the single-support oil wedge-shaped spindle assembly, the improved dual-support oil wedge-shaped dynamic pressure spindle assembly for the conical roller coreless grinding machine has the advantages of high machining and rotating precision and large grinding force.

Description

technical field [0001] The invention relates to a bearing processing and manufacturing equipment, in particular to a double-supported oil wedge-shaped dynamic pressure spindle assembly for a centerless grinder used for processing tapered rollers. Background technique [0002] At present, the domestic processing of bearing tapered rollers mainly adopts single-support oil wedge grinding wheel spindle assembly (the grinding wheel is suspended on the spindle head) or rolling bearing double-support type. In production practice, it is found that using a centerless grinder to process tapered rollers with a single-support oil wedge grinding wheel spindle assembly has the problems of low rotation accuracy, small grinding force, and small surface roughness of the product. Contents of the invention [0003] The object of the present invention is to provide an improved tapered roller centerless grinder double-supported oil wedge dynamic pressure spindle assembly with high rotation pre...
