Rolling bearing radial clearance intelligent design method based on body

Abstract

The invention belongs to the technical field of rolling bearing clearance design and computer-aided tolerance design (CAT), and particularly relates to a rolling bearing radial clearance intelligent design method based on a body. The method specifically comprises the following steps: (1) constructing a body representation model of the radial clearance of the rolling bearing; (2) establishing an SWRL reasoning rule of the radial clearance of the rolling bearing; (3) extracting tolerance information related to the radial clearance of the rolling bearing; (4) establishing an instantiated body model of the radial clearance of the rolling bearing; and (5) combining the Jess inference machine with the SWRL rule, inferring the radial clearance of the rolling bearing, and outputting a result inference result. According to the method, the body theory is introduced into the design of the radial internal clearance of the rolling bearing, an inference knowledge framework of the radial internal clearance of the rolling bearing based on body pairs is constructed, implicit knowledge is inferred according to explicit domain knowledge, and the knowledge base of the rolling bearing is expanded. Theinvention provides a consistency knowledge description framework in the field of the radial clearance of the rolling bearing, so that a computer can automatically select a reasonable radial clearancegroup and a reasonable clearance value according to the actual working condition environment of the rolling bearing, and a feasible method is provided for intellectualization of the radial clearance of the bearing.

Description

technical field [0001] The invention belongs to the technical field of rolling bearing clearance design and computer-aided tolerance design (CAT), and in particular relates to an intelligent design method for rolling bearing radial clearance based on a body. Background technique [0002] The selection of the radial clearance of rolling bearings is the core link for the long-term stable operation of the shafting parts of the product. It directly affects the technical performance of the bearings such as load distribution, vibration, noise, wear, temperature rise, service life and mechanical operation accuracy, and then affects The performance of the whole machine product where it is located. If the clearance is too large, in extreme cases, only the lowest rolling element may be stressed, the bearing capacity will be greatly reduced, the stress on the rolling contact surface will increase, the running accuracy of the bearing will decrease, the vibration and noise will increase,...
