Problems solved by technology

[0002] The existing tensioner pulley has high technical requirements for installers. If the position of the timing tensioner pulley is installed incorrectly, two problems will occur in the working process of the tensioner pulley, such as whistling and belt vibration. May excite vibrations in the tensioning spring, which can cause premature wear of the tensioning pulley and belt, affecting product and belt life

Embodiment Construction

[0028] Such as Figure 1 to Figure 9 The illustrated tensioner bearing unit with an asymmetrical damping structure includes a mandrel 4 , a sleeve 7 mounted on the mandrel, a bearing 8 mounted on the sleeve 7 , and a tensioner spring 72 . At the same time, the present invention adds a set of spring damping mechanism inside the tensioning wheel, and the spring damping mechanism includes: the first spring seat 1, the second spring seat 2 and the rectangular spring 3, the first spring seat 1 and the second spring seat 2 and the rectangular spring The springs 3 are combined and installed on the mandrel 4, the rectangular spring 3 is fixed with the first spring seat 1, so that the first spring seat 1 and the rectangular spring 3 rotate together, and the rectangular spring 3 and the second spring seat 2 are Clearance fit ensures that the automatic tensioner can rotate freely when it is working. The axial first side of the sleeve is provided with a limiting groove 71 partially exten...

Abstract

The invention discloses a nonsymmetrical damping structure tensioning wheel bearing unit. The nonsymmetrical damping structure tensioning wheel bearing unit comprises a mandrel, a sleeve and a bearing; the sleeve is mounted on the mandrel, and the bearing is mounted on the sleeve; a spring damping structure is further mounted on the mandrel, and the spring damping structure comprises a first spring seat, a second spring seat and a rectangular spring which are combined together; and the rectangular spring is fixed with the first spring seat, the rectangular spring is in clearance fit with the second spring seat, a limiting groove partially extending in the circumferential direction is formed in a first side of the axial direction of the sleeve, a limiting boss inserted into the limiting groove is arranged at a second end of the axial direction of the second spring seat, and the circumferential length of the limiting groove is longer than that of the limiting boss. According to the nonsymmetrical damping structure tensioning wheel bearing unit, vibration in the operating process of a belt is reduced, the service life of the bearing and the belt is prolonged, and the noise in the speed changing process of an automobile is reduced.

Description

technical field [0001] The invention relates to auto parts, in particular to a tensioning wheel. Background technique [0002] The existing tensioner pulley has high technical requirements for installers. If the position of the timing tensioner pulley is installed incorrectly, two problems will occur in the working process of the tensioner pulley, such as whistling and belt vibration. Vibrations may be induced in the tensioning spring, which can cause premature wear of the tensioning pulley and belt, affecting product and belt life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an asymmetrical damping structure tensioner bearing unit, which ensures that during the working process, the damping structure can rotate in the clockwise direction, and only the reserved position can be rotated in the opposite direction, and the tensioning wheel will be gradually and automatically Adjust the wheel to the best position....
