Abstract

The invention relates to a needle roller bushing and its auxiliary assembly structure, wherein the needle roller bushing includes a plurality of needle rollers and three end retaining rings, and the plurality of needle rollers are movably installed on the first end retaining rings. Between the ring and the second end retaining ring; a plurality of needle rollers are movably installed between the second end retaining ring and the third end retaining ring; the needle rollers include a cylindrical needle roller body and a cylindrical needle roller body The hemispheres at both ends of the first end retaining ring and the third end retaining ring are provided with a circle of grooves on the surface facing the needle; the two ends of the second end retaining ring are respectively provided with a circle of grooves; the hemisphere is movable set in the groove. The needle bushing of the invention can greatly reduce the frictional force during relative motion, improve mechanical efficiency, performance and reliability, and reduce energy consumption. The needle bushing auxiliary assembly structure of the present application can not only assist the assembly of the needle bushing, but also play a role of fixing and protection during transportation.

Description

Technical field [0001] The invention belongs to the technical field of bushings, in particular to a needle roller bushing and its auxiliary assembly structure. Background technique [0002] Bushings are widely used in automobiles or other machinery. The functions of the bushings in different structures are also different. Some have the function of rotation and wear resistance, and some have the function of rotation and flexible shock resistance. [0003] The inner ring and outer ring of the bearing rotate at a certain speed, but the bush is different from the bearing. The parts inside the bush and the parts outside the bush rotate within a certain angle range. figure 1 Part of the structure diagram of the front axle of the automobile, including wheel hub assembly 01, steering knuckle 02, outer bearing 03, inner bearing 04, lower bushing 05, tie rod ball pin 06, I-beam 07, steering knuckle arm 08, king pin 09 And the upper bushing 010; the upper bushing and the lower bushing between...
