The invention aims at providing a bearing clearance measuring device, so as to solve the technical problem of bearing radial clearance measurement. The bearing clearance measuring device comprises a measuring platform, a compressing and fixing mechanism, a base, a measuring instrument and a measurement movable arm mechanism, wherein the measuring platform is provided with a reference hole for mounting the base and a positioning through hole for enabling the upper end of the compressing and fixing mechanism to pass through; the compressing and fixing mechanism comprises a compressing piece anda compressing rod, the compressing rod is arranged in the positioning through hole in a vertical sliding mode, the compressing piece is in matched connection with the upper end of the compressing rod,and the lower end of the compressing piece is used for compressing and fixing the inner ring of the bearing; the measurement movable arm mechanism is arranged at one side of the measuring platform, the power output end of the measurement movable arm mechanism is provided with the measuring instrument, and the measuring head at the front end of the measuring instrument and the base are arranged correspondingly. The bearing clearance measuring device has the beneficial effects that the operation is simple, the bearing radial clearance measurement precision is high, radial clearance measurementon multiple types of bearings can be realized, and the operation is flexible.
Description
technical field [0001] The invention relates to the technical field of bearing measuring devices, in particular to a bearing clearance measuring device. Background technique [0002] Bearing clearance is also called bearing clearance. The so-called bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing box, the inner ring or the outer ring is fixed, and then the unfixed side of the bearing clearance is moved radially or axially . According to the direction of movement, it can be divided into radial clearance and axial clearance. The size of the clearance during operation (called working clearance) has an impact on the rolling fatigue life, temperature rise, noise, vibration and other performance of the bearing. In the prior art, a feeler gauge is usually used for inspection. Although the feeler gauge inspection method is simple to operate, it has large errors and cannot accurately measure the radial clearance of the b...
