Embodiment Construction
[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0041] Such as figure 1 As shown, the cam-based chain tensioner provided by the present invention includes: a fixed shaft 100 , a tensioning cam 200 , a support arm 300 and a shock-absorbing support device 400 .
[0042] Wherein, the fixed shaft 100 is fixed and plays a fixed role, and torsion springs are arranged on both sides of the fixed shaft to ensure that the chain runs more smoothly during the transmission process.
[0043] One end of the tensioning cam 200 is sleeved on the fixed shaft 100 and can swing around it. The outer side of the tensioning cam 200 is provided with a smooth groove for placing a chain. The base circle part of the tensioning cam 200 is concentric with the fixed shaft 100. And can swing around the fixed shaft 100, the cam lift outside of the tensi...
