Abstract

The invention relates to a friction moment measuring device for angular contact radial bearings. The friction moment measuring device comprises a device base, a spindle and a spindle driving device used for driving the spindle to rotate; a bearing mounting seat is fixed to the device base, the bearing mounting seat is provided with an inner hole for allowing the to-be-measured angular contact radial bearings to be mounted, and an outer ring stopping structure used for being in stopping fit with outer rings of the corresponding ends of the paired angular contact radial bearings combined face toface is arranged at one end of the inner hole; an axial loading device used for loading outer rings of the other ends of the angular contact radial bearings is arranged at the position, on the devicebase, of the other end of the inner hole; the spindle is provided with shaft shoulders, wherein each shaft shoulder is used for being arranged between the inner rings of the two paired angular contact radial bearings in a clamped mode so as to be fixed to the inner rings; and a torque sensor is arranged between the spindle driving device and the spindle. By adjusting the axial loading device, theaxial loading force of the outer rings of the angular contact radial bearings can be adjusted in real time.

Description

technical field [0001] The invention specifically relates to a friction torque measuring device of an angular contact radial bearing. Background technique [0002] Angular contact radial bearings are separable bearings, and are generally installed in pairs back-to-back or face-to-face. The friction torque of the bearing is one of the important parameters reflecting the performance of the bearing. However, the bearing friction torque testing equipment is not yet popular in the field of bearings. The friction torque of the bearing will be tested only when the host manufacturer has technical requirements. The test conditions of the contact radial bearing friction torque measuring instrument are often different from the actual working conditions, and it is not convenient to select and optimize angular contact radial bearings with the bearing friction torque performance under a certain working condition as the optimization goal. Moreover, the existing method of measuring bearing...
