本文论述了非共轭啮合的滚子链传动应有的正确啮合条件,指出爬链是链传动不正常啮合的集中表现。文章讨论了滚子链传动啮合过程、围链轮齿受载规律,链条节距与链轮弦节距以及链轮安装误差极限等问题,并分析了造成爬链的力学和和几何条件,最终提出了以保证传动过程中不发生爬链为前提的滚子链传动正确啮合条件。
This paper discusses the proper meshing conditions of roller chain transmission with non-conjugate meshing and points out that chain-climbing is a concentrated manifestation of abnormal meshing of chain drive. The paper discussed the meshing process of roller chains, the loading rules of the chain teeth, the pitch of the chain, the pitch of the sprocket and the limit of the error of the sprocket installation, and analyzed the mechanics and geometric conditions of the chain, finally Proposed in order to ensure that the transmission process does not occur on the premise of the correct chain roller chain meshing conditions.
