[0027] The present invention will be further described below with reference to the drawings and embodiments.
[0028] The measurement method is based on the relative displacement of the inner and outer rings of the bearing.
[0029] Combine figure 1 , A test bench for measuring radial working clearance of bearings, including drive motor 1, motor base 11, coupling 2, fulcrum one 3, left support 31, tested fulcrum 4, eddy current sensor 49, middle support 41. Hydraulic cylinder 5, rotating shaft 6, fulcrum two 7, right support 71 and bottom platform 8.
[0030] The coupling 2 is an elastic coupling or a rigid coupling, one end of which is connected to the rotating shaft 6 to drive the rotating shaft 6 to rotate, and the other end is connected to the driving motor 1; the driving motor 1 is connected to the motor base 11 through bolts The upper surface of the fulcrum 3 and the fulcrum 2 are fixedly connected; the fulcrum 1 3 and the fulcrum 2 7 adopt a double deep groove ball bearing su...
