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.
