Detailed Description
In a first embodiment, referring to fig. 1, the utility model discloses a joint bearing combined motion test device, it includes the bearing frame 10 that is used for installing joint bearing 70, cup joints supporting core axle 20 in joint bearing 70's the inner circle, be used for exerting the loading mechanism 30 of load to supporting core axle 20, angle adjusting block 40, change pendulum actuating mechanism 50, aligningA drive mechanism 60. The joint bearing 70 to be tested is arranged in the bearing seat 10, the bearing seat 10 is arranged on the upper surface of the angle adjusting block 40, and the angle adjusting block40Is arranged to intersect with the axis of the support spindle 20, so that the tilt angle β of the joint bearing 70 is adjustable，Thereby simulating different working conditions, the loading mechanism 30 comprises a hydraulic oil cylinder, and a piston rod of the hydraulic oil cylinder is connected withIn thatThe support mandrel 20Both ends of (2)In order to apply a pushing or pulling load, the angle adjusting block 40 is mounted on the aligning driving mechanism 60, and in this embodiment, the rotation and swing driving mechanism 50 is connected to the angle adjusting block 40 in a driving manner, so that the angle adjusting block 40 performs rotation and swing motion around the central axis of the support mandrel 20. The swing driving mechanism 50 is a servo motor or a swing cylinder, and the aligning driving mechanism 60 is a servo motor or a swing cylinder.
During the test, the aligning drive mechanism 60 drives the angle adjusting block 40 to rotate back and forth within a certain angle, so that the outer ring of the joint bearing 70 performs aligning motion; then, the rotation and swing driving mechanism 50 performs a back and forth rotation around the axis of the inner hole of the joint bearing 70 at a certain angle while performing the aligning motion, so as to drive the outer ring of the joint bearing 70 to perform the rotation and swing motion; thus, the composite motion of rotation and swing and centering of the joint bearing 70 can be realized; by controlling the movement angles and frequencies of the center adjusting drive mechanism 60 and the swing drive mechanism 50, various complex compound movements can be realized.
During the swing, the loading mechanism 30 simultaneously applies a load to the knuckle bearing 70, the load may be a tension or a compression, and the load is transferred: the loading mechanism 30 → the support core shaft 20 → the inner race of the joint bearing 70 → the outer race of the joint bearing 70 → the bearing housing 10 → the angle adjustment block 40 → the swinging drive mechanism 50 → the aligning drive mechanism 60; the angle control angle beta of the angle adjusting block 40 can be changed to simulate the working conditions of the joint bearing 70 under various composite loads.
The second embodiment, as shown in fig. 2, is different from the first embodiment in that: the rotating mechanism 70 drives the supporting mandrel 20 to perform a rotating and swinging motion around the central axis thereof, the rotation of the supporting mandrel 20 drives the rotation of the inner ring of the joint bearing 70 to further simulate a rotating or swinging motion, and the aligning motion mechanism 80 is directly connected with the angle adjusting block 40 to further simulate an aligning motion.
