Embodiment Construction
[0023] Such as Figure 1-Figure 4 As shown, the combined measurement device for back-to-back angular contact ball bearings with back-to-back installation in pairs, relative displacement, and rotational friction torque is measured from top to bottom by the pulling and sensing mechanism, bearing mounting base, transmission and rotational friction torque The organization consists of three parts.
[0024] The pulling and sensing detection mechanism is connected and installed on the rolling linear guide rail pair 3 of the bearing installation base by the column 6, and can move along the rolling linear guide rail pair, and its position is determined by the positioning block 4, the travel limit block 5, and the rear limit block 2. Position, to adapt to the measurement of bearings of different specifications; the transmission and rotation friction torque measurement mechanism is installed on the base 1 in the bearing installation base part through the motor base 23, and the pull in th...

The invention provides a back-to-back paired mounting angular contact ball bearing parameter combination measuring device and aims at overcoming uncertainty and blindness in manual assembly and calibration processes. The back-to-back paired mounting angular contact ball bearing parameter combination measuring device is composed of a drawing and sensory detection mechanism, a transmission and rotation friction torque measuring mechanism and a bearing installation base. The drawing and sensory detection mechanism is arranged on a rolling linear guide rail pair of the bearing installation base in connection mode through a column, and the position of the drawing and sensory detection mechanism is determined by a positioning block, a stroke limit block and a back limit block. The transmission and rotation friction torque measuring mechanism is arranged on a base disposed in the bearing installation base portion through a motor base, drives a drawing sleeve arranged in the bearing installation base and a bearing inner ring to rotate through a coupler and a transmission rod, and is used for measuring rotating friction torque. By adopting the back-to-back paired mounting angular contact ball bearing parameter combination measuring device, under certain axis accuracy and practical lubricating conditions, values of pretightening force, relative displacement and rotating friction torque of paired mounting angular contact ball bearings can be accurately determined.
Description
technical field [0001] The invention relates to a device for measuring parameters of angular contact ball bearings, in particular to a device for measuring pretightening force, relative displacement and rotational friction torque of angular contact ball bearings installed in pairs back to back. Background technique [0002] In the installation process of precision shafting, the installation of diagonal angular contact ball bearings is very important and is the main factor affecting the accuracy of the entire shafting. The classic installation methods of diagonal angular contact ball bearings can be divided into two categories: face-to-face pair installation and back-to-back pair installation. [0003] The relationship between the preload and relative displacement of angular contact ball bearings installed in pairs is: the greater the bearing preload, the greater the relative displacement, and at this time the greater the rotational friction torque, and the higher the accurac...
