石油钻机上广泛使用着滚子链传动。延长链条使用寿命,不但可以节省大量传动链条,更有意义的是可以提高钻机的使用率并避免因断链而引起的重大事故。影响链传动工作性能和使用寿命的因素是多方面的,实践证明:正确使用是十分重要的一个方面。 由于滚子链传动是一种具有中间挠性件(链条)的非共轭啮合传动,它有其本身固有的工作特性。所谓正确使用,就是要保证链传动在良好的工作条件下服役,这主要反映在三个方面,即正确的安装、合理的张紧与足够的润滑。
Roller chain drive is widely used on oil rigs. Extend the service life of the chain, not only can save a lot of transmission chain, more meaningful is to improve the utilization rate of drilling rig and avoid the chain caused by a major accident. There are many factors affecting the performance and service life of chain drive. Practice has proved that proper use is a very important aspect. Since the roller chain drive is a non-conjugate meshing transmission with an intermediate flexure (chain), it has its own inherent operating characteristics. The so-called correct use, is to ensure that the chain drive in good working conditions in service, which is mainly reflected in three aspects, that is, the correct installation, reasonable tension and adequate lubrication.
