滚子链传动的设计与计算 摘 要 链传动是通过链条将具有特殊齿形的主动链轮的运动和动力传递到具有特殊齿形的从动链轮的一种传动方式。主要适用于要求工作要求可靠，两轴相距比较远，不适合采用齿轮传动，需要平均传动比准确但不需要瞬时传动比准确的场合。它可以用于工作条件恶劣的场合，广泛应用于建筑机械、农业机械、石油机械、起重、采矿、金属加工机床、摩托车、自行车等。 链传动有很多优点，与带传动相比，它无弹性滑动和打滑现象，平均传动比准确，工作可靠，效率高；传递功率大，过载能力强，在相同工况下的传动尺寸小，能在高温、潮湿、多尘等恶劣的场合下工作。 本毕业设计是在韩国东洋链条贩卖株式会社杭州办事处进行的。主要设计资料及进行的绘图都是在该公司完成的。首先介绍了链条的种类以及链传动的运动特性，其次根据实际工程机械出现的问题，查阅机械设计手册，进行滚子链传动的设计，并检验链速，压轴力等条件，核实是否满足实际条件，计算出具体的链条以及链轮的尺寸参数，并运用Autocad、caxa绘图软件，绘制相关的零件图和装配图，解决工程实际输送问题。 关键词：滚子链传动 链条 链轮 设计 Design of Roller Chain Drives and Calculation Student: Huang haijie Advisor: Dr. Qiang Li School of Zhejiang Abstract Chain of transmission is through the chain which have a special tooth movement and the active power transmission sprocket to the driven sprocket tooth with a special kind of drive。The main requirement for reliable, far away from the two axes, gear should not be used, requiring an average transmission ratio accurate but is not required where the instantaneous transmission ratio accurately. It can be the occasion for the poor working conditions, are widely used in agricultural machinery, construction machinery, petroleum machinery, mining, lifting, metal cutting machine tools, motorcycles, bicycles .and so on. chain drive has many advantages compared with belt drive, inelastic sliding and skidding, the average transmission ratio accurate, reliable, high efficiency; transmission power, strong overload capacity, small size, the same transmission conditions, in high temperature , humid, dusty, there is pollution and other adverse environments I do the graduation project in DONGYANG CHAIN SALES CO .LTD. Main design data and the graphics are done in the company. I first introduced the type of chain and chain drive of the motion characteristics. Second, according to the actual problems of construction machinery, access to mechanical design manual for the design of roller chain drives, and test chain speed, power and other conditions of the finale, to verify whether the ac
