摘　　要：针对目前摆线针轮减速传动需要专门的输出机构、体积大、振动大等缺点,提出了一种摆线轮作定轴传动的新型定轴摆轮传动机构。分析研究了该机构的传动原理和传动结构;推导了摆线轮基本参数计算公式和齿廓方程;设计制造样机,并在齿轮传动试验台上对该样机性能进行了测试,结果表明该减速器在额定工况下传动效率可达91.9%,最大振动速度有效值为3.09mm/s,最大结构噪声为101.6dB。The current cycloid reducer drive has the shortage of needing special output mechanism,large volume and high vibration.To solve this problem,a new gyratory fixed-spindle cycloid drive is designed.The drive principle of the reducer is introduced.Formula for calculating the basic parameters and tooth profile equation of cycloid gear are derived.On the basis of discussion of the mechanism and the principles of gear connection,a prototype is designed and manufactured.The results of the prototype test on the gear test rig indicate that the transmission efficiency of the new drive may reach 91.9% at rated operating conditions,the biggest vibration velocity effective value is 3.09 mm/s,and the biggest structure noise is 101.6 dB.
