Embodiment Construction
[0018] Structurally, the test device for the axial bearing capacity of the conical dynamic pressure spiral groove bearing consists of a mechanical part and an electric control part. The mechanical part includes: test device frame, transmission shaft, bearing seat ring, washer, damping ring, loading sleeve, split positioning ring, ball, loading lever, strain beam; the electronic control part includes: frequency converter, high frequency motor, Dynamic and static strain gauges.
[0019] The high-frequency motor is installed on the upper part of the test device frame, connected with the frequency converter, and the test bearing is connected with the motor shaft. The test housing is located inside the bearing race. The bearing race is located under the drive shaft and fits inside the damping ring. The damping ring is located between the bearing load sleeve and the bearing race. A U-shaped groove is opened in the loading sleeve, and the strain beam is embedded in it. The gasket...
