Automotive wheel bearing test machine cantilever supporting institutions and axial, radial loading mechanism
The utility model is bearing test detection technology. Automotive wheel bearings proposed testing machine cantilever supporting institutions and axial, radial loading mechanism, cantilever supporting institutions that have used the test wheel bearing inner ring positioning tooling bracket (27) and tooling panel (26), tooling transition connection flange (16) and the test wheel bearings (17) coupled and fixed to coat the loading axis (5) of the end face of the test bearing cantilevered bearing; axial load and radial load mechanism has a loading structure indirect, indirect loading structure comprises loading arm (15), loading sheath (14), tapered roller bearings (4), and the loading axis (5) end tooling transition flange coupling (16), wherein the loading arm (15) perpendicular to the loading axis (5) and with the axial loading cylinder (11) perpendicular to the radial loading cylinder (1) parallel to the load sleeve (14) and loading arm (15) fixedly connected to and between loading shaft (5) with the addition
Morse company developed and tested automotive generator bearing verifyinstallation, and commissioning work, through a type of self- lubricating taper roller bearing for friction and wear performance test to verify the test machine performance, this model also discussed joint bearing wear mechanism. The main research work is as follows: For the composite swing, high frequency, heavy self-lubricating bearings under conditions of friction and wear performance, service life and reliability of the design of the testing machine program, which implements joint bearing composite swing, breaking the current reported joint bearing testing machine wobble frequency does not exceed the limit of 1Hz to solve the wobble frequency and contact pressure can not raise conflicts. Draw a testing machine assembly diagram and drawings of each part of the process to complete the testing machine powertrain, loading system and the measuring system installation and commissioning work. Through simulation and performance tests on the test machine main parameters of the error analysis, the results showed: These parameters relative errors are less than the current literature, or equivalent, to meet the test requirements of precision. Meanwhile measurement repeatability of test data and test machine for different joint bearing friction and wear tests were evaluated for effectiveness, proven high repeatability of the test machine, and can be of different test pad bearings. Through a type of self-lubricating bearings for tribology testing, analysis of different forms of swing, swing different frequencies and different pressures on self-lubricating bearings friction and wear performance, verify the test machine of each system design is reasonable, operation stability and accuracy of measurement data, etc., to achieve the desired design goals. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and three-dimensional topography profiler on self-lubricating bearings friction and wear surface microscopic analysis, discusses its wear mechanisms under different conditions, the results showed that: mainly extrusion wear, abrasive wear, adhesive wear and fatigue wear.
