The using method of this fixture is: pack oscillating bearing 9 into load plate 8, mandrel 14, through oscillating bearing 9, is withstood on left jacking block 5, right jacking block 12 respectively on two end faces of inner ring of oscillating bearing 9.During the test of oscillating bearing swinging wear-out life, loading system applies radial load by 8 pairs of oscillating bearings 9 of load plate, drive system uses key 15 to drive mandrel 14, mandrel 14 to drive left jacking block 5 by left flat key 4 by spindle nose, by right flat key 13, drive right jacking block 12, left jacking block 5 and right jacking block 12 are realized its periodic oscillations by frictional force drives oscillating bearing 9.
Mandrel 14 has 3 keyways, is not easy to processing, and has reduced the strength and stiffness of mandrel 14.When mandrel 14 swings, left flat key 4, right flat key 13 and spindle nose have applied load and moment with 15 pairs of mandrels of key, have increased load and moment that mandrel 14 bears.When mandrel 14 swings, left flat key 4, right flat key 13 and spindle nose produce and impact with 15 pairs of mandrels of key 14, and the probability that causes mandrel 14 to produce damage increases.In installing/dismounting process, left flat key 4, right flat key 13 and spindle nose need to be arranged in mandrel 14, left jacking block 5 and right jacking block 12 with key 15, increase installing/dismounting step, increase installing/dismounting intensity, reduce installing/dismounting efficiency.This test fixture complex structure, the probability breaking down is large, and installing/dismounting efficiency is low, and experimentation cost is high.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in structure, dependable performance, installing/dismounting intensity is little and efficiency is high, experimentation cost is low oscillating bearing swinging wear-out life test fixture.Technical solution of the present utility model is, oscillating bearing swinging wear-out life test fixture comprises a mandrel 14 without keyway, left top cover 20, right top cover 21, left support bearing 6, right support bearing 11, left support abutment 7 and right support abutment 10 and load plate 8, mandrel 14 passes successively right top cover 21, is arranged on oscillating bearing 9 and left top cover 20 in load plate 8, the flanged one end of right top cover 21 is connected with drive system, and the other end withstands on an inner ring end face of oscillating bearing 9; Mandrel 14 has the shaft shoulder, the shaft shoulder withstands on the flanged end face of right top cover 21, the spindle nose of mandrel 14 has external thread, nut 1 on mandrel 14 spindle noses, spring washer 2, plain washer 3 make another inner ring end contact of left top cover 20 and oscillating bearing 9, and left top cover 20 and right top cover 21 are clamped the inner ring of oscillating bearing 9; Left support bearing 6 is housed in left support abutment 7, right support bearing 11 is housed in right support abutment 10, left top cover 20 is contained in left support bearing 6, and right top cover 21 is contained in right support bearing 11.
The advantage the utlity model has and beneficial effect: the mandrel in this oscillating bearing swinging wear-out life test fixture, because axle body and spindle nose all do not have keyway, so increased the strength and stiffness of mandrel, has also reduced load and moment that mandrel bears.Left top cover and right top cover are utilized the shaft shoulder of mandrel and the nut on mandrel spindle nose, spring washer, plain washer clamps oscillating bearing, drive system utilizes the frictional force drives oscillating bearing between part in test fixture to realize its periodic oscillations, test fixture does not adopt key and spindle nose key for axle body, so dependable performance, simple in structure, be convenient to processing, reduced test fixture cost, easy installation and removal, reduced installing/dismounting intensity, improved installing/dismounting efficiency, avoided the impact of key, reduced testing failure probability of happening, improved the stability of test fixture, saved test period, reduced experimentation cost.
