Gap detection device of large slewing bearing

Abstract

The invention provides a gap detection device of a large slewing bearing and belongs to the technical field of industrial measurement. The gap detection device comprises a radial error detection table, three groups of symmetrically-distributed axial error detection tables, a detection working table frame with a spiral pressing plate clamping mechanism, a slewing bearing to be detected, a controller and a displayer. Each axial error detection table comprises an axial servo motor, an axial rolling guide rail, an axial ball screw, a centering mechanism, an axial screw nut, an axial servo electric pushing rod, an axial working table plate, an axial base and an axial displacement sensor. The radial error detection table comprises a radial servo motor, a locking mechanism, a radial ball screw, a radial rolling guide rail, a radial screw nut, a radial working table plate, a radial servo electric pushing rod, a fork head, a radial base and a radial displacement sensor. The gap detection device of the large slewing bearing has the advantages of being high in detection accuracy, convenient to operate and high in detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of industrial measurement, and in particular relates to a large-scale slewing bearing clearance detection device, which is used for detecting the axial and radial clearances of the installed inner and outer rings of the large-diameter slewing support. Background technique [0002] The axial and radial clearance detection between the inner and outer rings of large slewing bearings has always been a major problem in the industry. At present, the traditional manual detection method is often used: for axial clearance detection, the specific method is to place the slewing bearing on a working platform, and several inspectors use the crowbar to pry the different fulcrums of the inner ring (or outer ring) of the slewing ring at the same time , and then use the dial indicator to measure the height difference at different positions of the end faces of the inner and outer rings of the slewing bearing, and take the ave...

Problems solved by technology

[0003] The diameter and weight of large-scale slewing bearings are relatively large. The above-mentioned traditional manual inspection method is not only labor-intensive and inefficient, but also because the inspectors use the dial indicator to record the measurement results by manual reading, there are visual errors and increase. Increases the possibility of accidental errors, making the test results unreliable

[0004] It can be seen from the above that there is currently no simple, direct and high-precision method for automatic detection of the axial and radial clearances between the inner and outer rings of large slewing bearings.
