Abstract

The invention relates to a roller pin bush and an auxiliary assembling structure of the roller pin bush. The roller pin bush comprises multiple roller pins and three end retaining rings. Multiple roller pins are movably mounted between the first end retaining ring and the second end retaining ring. Multiple roller pins are movably mounted between the second end retaining ring and the third end retaining ring. Each roller pin comprises a cylindrical roller pin body and hemispheroids at the two ends of the cylindrical roller pin body. The surface, facing the corresponding roller pins, of the first end retaining ring and the surface, facing the corresponding roller pins, of the third end retaining ring are each provided with a groove in a circle. The two ends of the second end retaining ring are each provided with a groove in a circle. The hemispheroids are movably arranged in the grooves. 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. The 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 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...
