Embodiment Construction

[0037] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0038] The invention provides a needle bushing, such as Figure 5 to Figure 11 As shown, it includes a plurality of needle rollers 1 and a cage 2; the cage 2 is cylindrical; a circle of grooves 21 is provided on the inner surface of the cage; a plurality of needle rollers 1 are movably installed In the groove 21; in the present application, the outer surface of the cage is a cylindrical surface to fit better with the inner surface of the mounting hole.

[0039] The needle roller 1 is a cylindrical structure with high cylindricity; multiple needle rollers are evenly distributed in the groove, and there is a small gap between two adjacen...

Abstract

The invention relates to a roller pin bush, comprising a plurality of roller pins and one retainer, wherein the retainer is cylindrical, the inner side surface of the retainer is provided with a circle of groove, the plurality of roller pins are movably installed in the grooves, the roller pins are of a cylinder structure, and the diameters of the roller pins are greater than the depth of the groove. The roller pin bush provided by the invention can greatly reduce frictional force during relative movement, improves mechanical efficiency, performance and reliability and lowers energy consumption. The assembly-assisting structure for the roller pin bush can assist assembly of the roller pin bush and exerts fixing and protecting effect during transport of the roller pin bush.

Description

technical field [0001] The invention belongs to the technical field of bushings, in particular to a needle roller bushing and its auxiliary structure. Background technique [0002] Bushings are widely used in automobiles or other machinery, and the functions of bushings in different structures are also different. Some of them play the role of rotating and anti-wear, and some play the role of rotating and flexible anti-seismic. [0003] The inner ring and the outer ring of the bearing rotate at a certain speed relative to each other, but the bush is different from the bearing, and the parts inside the bush and the parts outside the bush rotate within a certain angle range. figure 1 It is a schematic diagram of the structure of the front axle of the car, including 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, kingpin 09 And the upper bushing 010; wherein the upper bushing an...
