Abstract

The invention discloses a method for obtaining a working clearance of a bearing through combination of a test and numerical calculation. The method comprises the following steps: (1) firstly, acquiring a radial relative deformation amount DELTA r of the bearing through a bearing test measuring device; (2) establishing a bearing mechanical model considering a working clearance in a bearing loaded state; (3) obtaining the relative deformation delta r of the inner ring and the outer ring of the bearing under different working clearances through numerical calculation; and (4) when the calculated deformation delta r is equal to the relative deformation DELTA r in the experimental test, taking the obtained working clearance as the actual working clearance of the bearing. According to the invention, the advantages of a test method and a numerical calculation method are fully combined, and a theoretical basis is provided for accurately predicting the service life and the working temperature rise of the bearing and actual model selection application.

Description

technical field [0001] The invention belongs to the technical field of measuring the working clearance of a bearing, and in particular relates to a method for obtaining the working clearance of a bearing by combining experiments and numerical calculations. Background technique [0002] Among various parameters of rolling bearings, clearance is a very important parameter in rolling bearings. According to the different state of the bearing, the clearance can be divided into original clearance, installation clearance and working clearance. Radial clearance means that when one ring of the bearing is fixed, the amount of movement of the other ring from one limit position to another limit position in the radial direction is an important index for evaluating the quality of cylindrical roller bearings. Radial accuracy of mating rotating parts. The working clearance of the bearing after installation, temperature rise and contact deformation has an important impact on the actual bea...
