Seal retention test device for self-aligning roller bearing

Abstract

The utility model discloses a kind of sealing retention test devices of self-aligning rolling bearing, including race and fixed shaft, race axial through hole, the inner peripheral wall surface of through hole is the contact surface for being contacted with the outer peripheral wall of outside bearing outer ring to be tested, fixed shaft initial end portion is provided with abutting head, the inner wall surface of abutting head is the abutting surface for being contacted with the lateral wall of outside bearing inner ring to be tested, the limit head for being matched with abutting head to realize the clamping limit of bearing inner ring to be tested is detachably connected on fixed shaft along its axial direction, fixed shaft terminal end portion is provided with the loading structure for being linked with outside hydraulic equipment to apply axial or radial or compound load to fixed shaft, limit structure for making outside bearing outer ring to be tested one-way limit is set on race.The utility model solves the problem that the operation of traditional sealing retention detection equipment of self-aligning rolling bearing is complex, resulting in detection efficiency reduction and being difficult to apply fast test, portable operation condition.
