Description
Technical Field
The invention relates to a device for measuring the bottom thickness of a slewing bearing isolation block.
Background
The isolating block is used in the raceway of the slewing bearing and used for isolating the slewing bearing rolling ball, so that the isolating block plays a role of a retainer and reduces unnecessary abrasion of a ball hardness layer. Two spherical crowns are symmetrically arranged on the outer surface of the cylindrical structural block body. The bottom thickness of the spacer is a relative distance to the adjacent balls to control the circumferential clearance of the rolling balls within the overall bearing. At present, a vernier caliper 2 is adopted when measuring the bottom thickness dimension X of an isolation block 1, two standard steel balls 3 are respectively placed in ball sockets at two sides of the isolation block 1 (as shown in fig. 1) during measurement, the vernier caliper 2 is used for measuring the maximum value L in the length direction after the two steel balls 3 clamp the isolation block 1, then the reading is subtracted by the marked diameter Φ of the two standard steel balls 3, and the obtained value is the bottom thickness dimension X of the isolation block 1.
The drawbacks of the above method are two-fold:
1) because the radius of the spherical crowns at the two sides of the isolating block is inconsistent with the radius of the steel ball, the radius of curvature of the steel ball is smaller than that of the spherical crown of the isolating block, and the degrees of freedom are easy to generate accumulative errors, the measurement repeatability and the reproducibility are poor;
2) the measurement value is related to the gesture of the operator and the force measured by the gesture, so the measurement precision is low.
