A device for detecting runout of a bearing assembly plane

Abstract

The invention discloses a runout detection device for an assembly plane of a bearing. The device comprises an upper positioning column installed on a rack, a lower positioning column which is installed on the rack and is coaxial to the upper positioning column, a detection ring arranged around the central axis of the lower positioning column and a lower jacking spring the upper end of which tightly jacks the detection ring; the lower jacking spring is arranged between the rack and the detection ring; the upper positioning column and the lower positioning column which are coaxially arranged areused for limiting the bearing to make the central axis of the bearing kept vertical, the lower jacking spring is deformed under stress to make the detection ring tightly fit the lower end face of thebearing, and the detection ring integrally feeds back the flatness and perpendicularity of the lower end face of the bearing; a presentation value caused by an error on the face of the bearing is amplified by the detection ring, the flatness and perpendicularity errors of the bearing are obviously reflected, and the test result is accurate and reliable.

Description

Technical field [0001] The invention relates to a detection device, in particular to a detection device for bearing assembly plane runout. Background technique [0002] Bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation precision. The accuracy, performance, life and reliability of the bearing play a decisive role in the mechanical product, and the bearing and the shaft Accuracy is related to whether the bearing can be installed as required. If the bearing with low installation accuracy is used, the test result is prone to beating. Generally, the bearing needs to be measured before leaving the factory. The measurement is usually manually measured by a measuring instrument to improve the test accuracy , Often use multi-point measurement, this test method has low accuracy of test results. [0003] In summary, there is an urge...

Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its precise rotation. The accuracy, performance, life and reliability of the bearing play a decisive role in the mechanical product, and the relationship between the bearing and the shaft Accuracy is related to whether the bearing can be installed as required. For bearings with low installation accuracy, the test results are prone to beating. Generally, the bearing needs to be measured before leaving the factory. The measurement is usually done manually by measuring instruments. In order to improve the test accuracy , often adopts the way of multi-point measurement, the accuracy of the test result of this test method is low
