Technical Field
[0001] The utility model relates to the technical field of bearing detection tooling, in particular to a handheld detection machine for bearing rotation torque. Background Art
[0002] According to different working conditions, the rotational torque of the bearing has different requirements. Some require low torque and low energy consumption, some require larger torque to monitor the rigidity of the bearing, and some require monitoring the influence of lubricating grease and seals on the rotational torque of the bearing. There are two traditional bearing torque detection methods. One is to fix the inner ring of the bearing, wrap a thin rope around the outer ring, apply tension to the thin rope, and obtain the bearing rotational torque by multiplying the tension value by the radius of the outer ring. The other method is to fix one bearing ring and install the other bearing ring on the torque meter. Several pre-opening holes will be opened on the inner ring and the outer ring of the bearing to be detachably connected with the external disk component through bolts. The bearing or disk component or torque meter is manually rotated to obtain the bearing rotational torque according to the torque meter reading. There are many problems with the above two detection methods. For example, the entire operation process is cumbersome and complicated, and the detection is easily disturbed by the outside world, which requires re-detection, that is, it cannot be detected efficiently. For example, the detection data is unstable. Due to artificial acceleration and rotation, the bearing rotational torque error exceeds 40%, which makes the detection result error too large.
