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

specific Embodiment approach
[0033] Specific embodiments: The specific embodiments of the present invention will be described in detail below with reference to the drawings:
Embodiment
[0034] Example: An automatic measuring instrument for the axial clearance of tapered roller bearings in automobile gearboxes (see Figure 1-Figure 6 ), it has a frame 10, the frame 10 is supported by four bottom corners 28, the front of the frame 10 is provided with a door 26 for opening.
[0035] The worktable 9 is fixed on the frame body 10. The lower end of the worktable 9 in the frame body 10 is provided with a lower outer pedestal 27. The lower outer pedestal 27 is equipped with a lower rotating shaft 21. The lower rotating shaft 21 is sleeved with a spring 37. The upper end is connected to the lower inner table 20, and the lower inner table 20 should be reliably reset under the action of spring force; the lower part of the lower shaft 21 is connected to the belt driven pulley 38, which does not affect the up and down movement of the lower shaft 21, and a steel ball 40 is pressed at its end as Loaded contacts.
[0036] The lower end of the workbench 9 is connected to the spee...

Abstract
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 therequirements 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. They have a wide range and extremely important role in various fields. There are many types and quantities of automobile bearings. Different parts and conditions of use have different requirements for bearings. Transmission bearings account for the largest proportion in automobiles. Tapered roller bearings and suitable bearing shafts occupy an important position in transmissions. The backlash contributes to the normal operation of the rolling bearing. If the clearance is too small, the temperature of the rolling bearing will rise, and it will not work normally, and the rolling elements will be stuck; if the clearance is too large, the equipment will vibrate and the roll...
