Abstract
The invention belongs to the technical field of tests, and relates to a swing wear life test clamp of a joint bearing. The strength and the rigidity of a central spindle of the swing wear life test clamp of the joint bearing are improved due to the fact that a spindle body and a spindle head of the central spindle are respectively provided with a key groove, and the load and torque borne by the central spindle are also reduced. A left ejection sleeve and a right ejection sleeve are used for clamping the inner circle of the joint bearing through nuts, spring washers, flat washers and a spindle shoulder of the central spindle. A drive system drives the joint bearing to achieve periodic swinging through the friction force between parts in the test clamp. Spindle body keys and spindle head keys are not used in the test clamp, so that the performance is reliable, the structure is simple, machining is convenient, the test clamp cost is lowered, mounting and dismounting are convenient, the strength of mounting and dismounting is reduced, the efficiency of mounting and dismounting is improved, impact of keys is avoided, the probability of occurrence of test faults is lowered, the stability of the test clamp is improved, the test time is saved, and the test cost is lowered.

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.When the test of oscillating bearing swinging wear-out life, loading system applies radial load by load plate 8 to oscillating bearing 9, 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, drive right jacking block 12 by right flat key 13, 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 key 15 to mandrel, have increased load and moment that mandrel 21 bears.When mandrel 14 swings, left flat key 4, right flat key 13 and spindle nose produce and impact mandrel 14 with key 15, 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 object of the invention 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 invention 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 that the present invention 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 nut on the shaft shoulder and the mandrel spindle nose of mandrel, 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 axle body key and spindle nose key, so dependable performance, simple in structure, be convenient to processing, reduce test fixture cost, easy installation and removal, reduce installing/dismounting intensity, improve installing/dismounting efficiency, avoid the impact of key, reduce testing failure probability of happening, improve the stability of test fixture, save test period, reduce experimentation cost.
