Problems solved by technology

At present, there are two main ways to rotate the object under test (bearing): one is to rely on manpower and rub it by hand, which will make the rotation speed of the bearing uneven, and it will not be uniform, and the most important thing is that the speed cannot reach Use requirements, low detection accuracy

Abstract

The invention relates to a tightness self-regulating rotating mechanism of a bearing performance precision detection instrument, which comprises a direct current brushless motor 19-1 and a tensioning air spring. The tightness self-regulating rotating mechanism is characterized in that the direct current brushless motor 19-1 and a driving wheel 19-2 are fixed together, the driving wheel 19-2 is movably arranged on a driving wheel shaft 20, the driving wheel shaft 20 is fixedly arranged on a left clamp plate 18 and a right clamp plate 21, the middle sections of the left clamp plate 18 and the right clamp plate 21 are respectively and fixedly provided with a centering shaft 17, two swinging arms 15 are movably arranged on each centering shaft 17 by a fourth bearing 31, a support shaft 16 is movably arranged in the middle of the swinging arms 15 by a third bearing 30, the middle of the support shaft 16 is movably provided with a support rod 26, the support rod 26 is connected with one end of the tensioning air spring 9, the other end of the tensioning air spring 9 is fixed on a fixed air cylinder seat 6, and the fixed air cylinder seat 6 is movably arranged on a fixed air cylinder shaft through a fixed air cylinder sleeve 8. The tightness self-regulating rotating mechanism realizes high-precision detection on the axial play, the assembly height and the end surface jumping of bearings, realizes the rotating kinetic energy required by the detection and can simulate real operation to achieve the full automation of the detection process.

Description

technical field [0001] The invention belongs to a bearing tester, in particular to a tightness self-adjusting rotating mechanism of a bearing performance precision tester. Background technique [0002] The axial clearance of the bearing is one of the key index parameters of the rolling bearing. The so-called internal clearance is the amount of clearance between the outer ring, inner ring and steel ball of the bearing. Generally, when the inner wheel is fixed, the amount of movement when the outer wheel moves up and down is called the radial clearance, and the amount of movement when the outer wheel moves in the left and right directions is called the axial clearance. In the operation of the bearing, the size of the internal clearance is the main factor of performance such as left and right vibration, noise, heat generation, fatigue life and rotation accuracy. The full runout of the end face is a comprehensive reflection of the shape error of the entire end face of the beari...
