摘要
在齿形链传动中,链条承受周期性的交变载荷,其中链节啮入轮齿时产生的冲击载荷影响较大。通过研究标准链条分别与直齿链轮和渐开线齿链轮啮合的啮合冲击,分析发现在链轮上采用渐开线齿能减小链条与链轮啮合瞬间的法向冲击速度,进而降低链条与链轮的啮入冲击。
In odontoid chain drive, the chain bears a periodical alternating load, in which the impact load produced while the link meshes into the tooth of sprocket makes comparatively big effect. By means of researching the meshing impact in. the engagement of standard chain respectively with the spur toothed sprocket and the involute toothed sprocket, it has been discovered through analysis that by adopting the involute tooth for the sprocket could reduce the normal impact velocity in the engaging instant of chain and sprocket, thus lowered the meshing impact among chain and sprocket.
