Abstract

The invention relates a kind of belt roller especially relates a kind of one-way belt roller used in cars. It has a shell and a mandrel and there is installing a one-way pillow between the shell and the mandrel; there is installed and fixed dust prevention cover; the internal sleeve of one-way pillow said above and the mandrel are the integral construction; the outer coating of one-way pillow has none edge fold and there is bindingly setting up a baffle ring at the two side faces of outer coating; there are setting up a base bearing and a supplementary bearing individually at the two terminals of one-way pillow. The one-way belt roller said about the invention has the merits like convenience assemblage, good wear-resisting property and long useful life period.

Description

technical field [0001] The invention relates to a pulley, in particular to a one-way pulley for automobiles. Background technique [0002] The pulley of the automobile generator is connected with the automobile engine through the belt, and the engine drives the generator to rotate. Therefore, when the speed of the engine changes sharply, the speed of the pulley will also change rapidly. However, due to inertia, the speed of the generator rotor and the speed of the engine are instantly out of sync, resulting in a series of problems such as belt slipping and jumping. The consequences are: [0003] 1. Severe wear occurs between the pulley, belt and tensioner, resulting in a reduction in the life of the entire gear train; [0004] 2. Generate a whistle; [0005] 3. The rapid change of speed will produce instantaneous impact force, which will affect the life of the generator. [0006] In order to overcome the above-mentioned negative effects brought about by the sudden change...
