Description

Technical Field

[0001] The utility model belongs to the technical field of tensioners, in particular to a wear-resistant structure of an engine tensioner. Background Art

[0002] The tensioner acts on the engine's timing belt or timing chain to guide and tighten it, keeping it in the best tension state at all times. It is generally divided into two modes: hydraulic and mechanical. They can automatically adjust the tension of the timing belt and timing chain.

[0003] Although the engine tensioner in the prior art can adjust the tension, it does not have good wear resistance. During long-term use, the tensioner wheel on the tensioner needs to be in friction contact with the timing belt or timing chain of the engine, which makes it easy to be damaged, shortening the service life of the engine tensioner. In order to solve the above problems, we propose an engine tensioner wear-resistant structure. Utility Model Content
