Embodiment Construction

[0042] 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.

[0043] The invention provides a needle bushing, such as Figure 5 to Figure 11 As shown, it includes a plurality of first needle rollers 1 , a plurality of second needle rollers 3 , a first cage 2 and a second cage 4 .

[0044] Both the first cage 2 and the second cage 4 are cylindrical; a circle of first grooves 21 is provided on the inner surface of the first cage 2, and a plurality of first needle rollers 1 are movably installed in the first grooves 21; in this application, the outer surfaces of the first cage and the second cage are both cylindrical, so as to fit better with the inner surface of the mounting hole.

Abstract

The invention relates to a roller pin bush. The roller pin bush comprises multiple first roller pins, multiple second roller pins, a first retainer and a second retainer. The first retainer and the second retainer are each in a barrel shape. The surface, at the inner side, of the first retainer and the surface, at the inner side, of the second retainer are each provided with a groove in a circle. The multiple first roller pins or the multiple second roller pins are each movably mounted in the corresponding groove. The diameter of each roller pin is greater than the depth of the corresponding groove. By means of the roller pin bush, friction force generated in the relative movement process can be remarkably reduced; mechanical efficiency, performance and reliability can be improved; and energy consumption can be reduced. An auxiliary assembling structure of the roller pin bush can assist in assembly of the roller pin bush and also can achieve the fixation and protection effect in the transportation process.

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, king pin 09 And the upper bushing 010; wherein the upper bushing a...
