Method for detecting multiple technical indexes of turntable bearing by using detecting platform

Abstract

The invention discloses a method for detecting multiple technical indexes of a turntable bearing by using a detecting platform. The method relates to the detecting platform (1) and detecting accessories, wherein the detecting accessories comprise a first dial gauge (2), a second dial gauge (4), a first upright post (5), a mandrel (6), a second upright post (7), a fastening bolt, a gauge block and a spring scale. In the method, an actual condition of the turntable bearing (3) is simulated, an outer ring radial runout value, an outer ring axial runout value, an actual measurement starting torque value, an actual measurement stationary torque value, an actual measurement height error mean value, an inner ring radial runout value and an inner ring axial runout value of the turntable bearing can be respectively detected under the same detecting environments and conditions by using the detecting platform and the detecting accessories, and the accuracy of the detected result is guaranteed. The detection method is simple and practical, can be used for detecting bearings of different specifications and types, and has instructive significance for detecting multiple technical indexes of the bearing simultaneously.

Description

technical field [0001] The invention belongs to the technical field of bearing detection, in particular to a method for detecting multiple technical indicators of a turntable bearing by using a detection platform. Background technique [0002] YRT series turntable bearings are combined axial and radial cylindrical roller bearings, which are composed of two thrust needle roller bearings and one radial cylindrical roller bearing. When the turntable bearing is used, the axial and radial preloads are applied. For the convenience of transportation and installation, multiple screw holes are opened on the inner ring and outer ring, and the whole set of bearings is fastened with positioning screws. [0003] Due to the special structure of the turntable bearing, there is no suitable testing instrument for the precision of the finished product, assembly height and torque at present, and the testing methods adopted by each manufacturer are also different. There is no uniform standard ...
