Middle -size and small -size angular contact bearing protrusion is weighed and is carried measuring equipment

The utility model provides a middle -size and small -size angular contact bearing protrusion is weighed and is carried measuring equipment, it detects technical field to relate to bearing protrusion volume, fix a position frock and load loading device on including setting up on the workstation, the pressure sensor who is equipped with the loading cylinder in the load loading device and is used for measuring loading cylinder power output size, on fix a position the frock and include the roof of a setting in load loading device top, be equipped with a holding ring on the roof bottom surface, the loading cylinder has the measured bearing frock of measured bearing to rise or descend through its piston main shaft drive installation, and apply the axial to the measured bearing and preload, the measured bearing is last when rising to with the holding ring contact position, the lower end face contaction of its outer lane and holding ring, the inner circle corresponds with the hole of holding ring, be equipped with displacement sensor on the roof, the hole of displacement sensor's gauge head follow holding ring stretches out downwards, and lie in by survey bearing inner race's up end position. The utility model discloses middle -size and small -size angular contact bearing can be satisfied and at the direct measurement who applys the volume of protrusion under the great condition of preloading, measurement accuracy is improved.
