Visual shaft sleeve lubrication test device for engineering machinery

Abstract

The invention relates to a visual shaft sleeve lubrication test device for engineering machinery, and belongs to the technical field of engineering machinery equipment. The device comprises a machinebase assembly, a pressure applying device, a sliding seat, a shaft seat, a hinge pin shaft, a transparent shaft sleeve and a pressure applying steel wheel device; the shaft seat for mounting the hingepin shaft is arranged on the sliding seat; the pressure applying device for pushing the sliding seat to move is arranged on one side of the sliding seat, and the pressure applying steel wheel deviceis arranged on the other side of the sliding seat; the periphery of the hinge pin shaft is sleeved with the transparent shaft sleeve; and the pressing steel wheel device is correspondingly arranged onthe outer circumference of the transparent shaft sleeve. The high-strength transparent material shaft sleeve is adopted, and the continuity and durability of a lubricating oil film generated by a grease outlet mode of the hinge pin shaft and a transparent shaft sleeve lubricating oil groove are visually observed. By changing the pressure between the transparent shaft sleeve and the pressing steelwheel, the purpose of simulating the stress condition of the actual working condition is achieved. The lubricating mechanism of engineering machinery hinge pin shaft lubricating grease is studied, ahinge pin shaft matched with engineering machinery, a lubricating oil channel of a shaft sleeve and a lubricating oil groove are developed, and the engineering machinery hinge point can work permanently and efficiently.

Description

technical field [0001] The invention relates to a visible shaft sleeve lubrication test device for construction machinery, which belongs to the technical field of construction machinery equipment. Background technique [0002] There are many kinds of construction machinery products and complex working conditions. The structure of hinged rotation on the frame and working device is widely used. Various functions of the machine are realized through the combination of various groups of rotating structures; The lubricated rotating structure with the pin shaft, due to the high intensity of the working conditions, a good lubricating oil film must be maintained between the bushing and the pin shaft to meet the requirements of continuous continuous operation of the machine. Otherwise, poor lubrication will lead to mechanical grinding sticking and shutdown if it is light; it will cause safety accidents and personal and property losses if it is serious; for this reason, the structure a...
