Problems solved by technology

However, the applied force is not easy to control, the axial clearance is too large, noise is generated, and the shell is elastically deformed, even if the deformation is small, it also affects the accuracy of the measured axial clearance
[0013] The above detection methods are all manually operated, with large human errors, time-consuming and labor-intensive in batch detection, and cannot meet market demand at all. Therefore, it is imperative to develop projects that can automatically detect and control bearing clearance equipment

Abstract

The patent refers to the field of 'measuring of length, thickness, or similar linear dimensions and angles, areas,irregularities of surfaces or contours'. The invention discloses an automatic axial internal clearance measuring meter for a tapered roller bearing of an automobile gearbox. The measuring meter is characterized by consisting of a frame (10), a workbench (9), a lower external pedestal (27), a lower rotating shaft (21), a lower internal table (20), a driven pulley (38), a steel ball (40), a speed regulating motor (2), a driving pulley (43), a pulley (44), a tensioning component (35), a load hanging plate (32), a lower load bracket (31) capable of moving up and down, a load rod (30), a load (29), a measurement hanging plate (22), a meter clip (24), an inductance measuring head (23), a measuring lever (25), a bracket (3), a yoke plate (5), a compressing cylinder (12), a bearing housing (6), a movable plate (4), a door-shaped bracket (8), a guide rod (7), a pressurizing cylinder (13), an upper external pedestal (16), an upper rotating shaft (15), an upper internal table (18), an air supply system and an electric operation box (14). The automatic axial internal clearance measuring meter ensures the safety and reliability of the bearing by controlling the accuracy of the axial internal clearance of the gearbox so as to meet the requirements on high load and high efficiency of the automobile gearbox and ensure driving safety of the automobile.

Description

Technical field: [0001] The invention relates to an automatic measuring instrument, in particular to an automatic measuring instrument for the axial clearance of an automobile double-row tapered roller bearing. Background technique: [0002] Bearings are one of the important basic parts of the machinery industry, and they play a wide and important role in various fields. There are many types and quantities of automobile bearings, and different parts and conditions of use have different requirements for bearings. Transmission bearings account for the largest proportion in automobiles, and tapered roller bearings occupy an important position in transmissions. Suitable bearing shafts Backlash contributes to the normal operation of rolling bearings. If the clearance is too small, the temperature of the rolling bearing will rise, and it will not work normally, so that the rolling body will be stuck; if the clearance is too large, the vibration of the equipment will be large, and...
