Embodiment Construction

[0049] 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.

[0050] The invention provides a needle bushing, such as Figure 5 to Figure 14 As shown, it includes multiple needle rollers 1 and two end retaining rings (2, 3); multiple needle rollers 1 are movably installed between the two end retaining rings.

[0051] The needle roller 1 includes a cylindrical needle roller body and hemispheres at both ends of the cylindrical needle roller body; the cylindrical needle roller body has a high cylindricity, which can basically reach the accuracy of the ball in the bearing; the two ends of the needle roller are hemispheres The body is used to reduce the friction with the end retaining ring; there is a...

Abstract

The invention relates to a roller pin bush and an assembly-assisting structure. The roller pin bush comprises a plurality of roller pins and two end retaining rings, wherein the plurality of roller pins are arranged between the two end retaining rings; each roller pin comprises a cylindrical roller pin body and semi-spheres at two ends of the cylindrical roller pin body; the surface, facing the of roller pins, of each end retaining ring is provided with a circle of groove; and the semi-spheres are arranged in the grooves. 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 upper bushing 010; Wherein the upper bushing and th...
