The invention relates to an angular contact
ball bearing dynamic parameter tester, comprising leveling
sizing blocks, an experiment platform, a T-shaped substrate, a displacement meter IPN (
interpenetrating polymer network) damping plate, displacement meter supports, location cylindrical pins, guide flat keys, a motor IPN damping plate, a
direct current motor, a TS-B elastic coupler, an
exciter support, an
exciter, an impedance head, an axial loading mechanism, a bearing
assembly, accelerator sensors, optical pens, a CHB digital readout instrument, a 24-V
direct current power supply, a CCS controller, a computer provided with CCSManager
software, a
signal conditioner, a
data collector, a computer provided with CRAS
software, a power
amplifier and a
motor speed regulator. Compared with the prior art, the angular contact
ball bearing dynamic parameter tester has the obvious advantages that the device is simple in structure, higher in positioning precision and test precision, capable of testing dynamic parameters of a bearing under different rotary speeds and different
axial load work conditions and strong in universality, and can be used for testing the dynamic parameters of bearings of different dimension series.
