The grinding equipment comprises main equipment, the grinding disc sleeving piece and a roller circular disc external system, the main equipment comprises a base, an upright column, a beam, a sliding table, an upper tray, a lower tray, an axial loading device and a main shaft device, and the roller circular disc external system comprises a roller collecting device, a roller transporting system, a roller arrangement system and a roller feed-in mechanism; the grinding disc sleeving piece comprises a pair of coaxially arranged first and second grinding discs of which the front surfaces are opposite to each other, the front surface of the first grinding disc comprises a set of linear grooves distributed on the base surface (right circular conical surface) of the first grinding disc in a radial form, the front surface of the second grinding disc comprises one or more spiral grooves distributed on the base surface (right circular conical surface) of the second grinding disc, and the sum of the cone apex angles of the base surfaces of the first and second grinding discs is 360 degrees. The grinding equipment has the precise processing capacity to process the rolling surfaces of mass tapered rollers.

Description

technical field [0001] The invention relates to a grinding disc kit, grinding equipment and a grinding method for finishing the rolling surface of a tapered roller, and belongs to the technical field of precision machining of bearing rolling bodies. Background technique [0002] Tapered roller bearings are widely used in various types of rotating machinery. As one of the important parts of tapered roller bearings, the shape accuracy and dimensional consistency of the rolling surface of the tapered roller have an important impact on the performance of the bearing. At this stage, the known machining process of tapered roller rolling surface is: blank forming (turning or cold heading or rolling), rough machining (soft grinding rolling surface), heat treatment, semi-finishing (hard grinding rolling surface) and finishing . The main process method of known tapered roller rolling surface finishing is superfinishing. [0003] Superfinishing is a fine-grained whetstone as an abra...

AI Technical Summary

Problems solved by technology

[0005] The above two methods of superfinishing the rolling surface of tapered rollers have the following two technical defects: on the one hand, the change of the wear state of the oil stone and the guide roller over time during the processing is not conducive to the improvement of the shape accuracy and dimensional accuracy of the rolling surface of the tapered roller; On the one hand, since the superfinishing equipment only processes a single (or a few) tapered rollers at the same time, the amount of material removal on the rolling surface of the processed tapered rollers is hardly affected by the difference in diameter of the rolling surface of the same batch of tapered rollers. Therefore, it is difficult to effectively improve the diameter dispersion of the processed tapered roller rolling surface by using superfinishing equipment to process the tapered roller rolling surface

Material removal on the roller surface during machining is uncertain, and this method cannot improve the dimensional accuracy and diameter dispersion of the roller
