3Z型行星齿轮减速器的设计【毕业论文+CAD图纸全套】.doc

优秀设计 3Z型行星齿轮减速器设计 摘要：这次毕业设计的内容是根据课题做一个行星齿轮减速器。通过比较，选用3Z(II)型行星齿轮减速器。 本次设计要完成的主要内容： 确定传动方案 传动方案的确定包括传动比的确定和传动类型的确定。 设计计算 每级传动结构的设计计算，大致包括：传动比的分配、传动系统运动学和动力学计算、传动零件的设计、轴的设计计算与校核、轴的选择与计算、键连接的选择与计算、箱体的设计、润滑与密封的选择和传动装置的附件说明等。 装配图以及各零件图的设计。 通过本次设计，可知行星齿轮减速器有着体积小、质量小、结构紧凑和传动效率高等特点，但由于行星齿轮减速器传动比大，力矩就比其它减速器结构小，行星齿轮减速器自锁角大止退性差而不适合启动用。 关键词：行星齿轮 减速器 设计计算 传动方案 指导老师签名： The design of 3Z planetary gear reducer Abstract: The content is based on graduate design to be a subject of planetary gear reducer. By comparing,3(II)Planetary gear reducer is selected . The design of the main elements to be completed: 1. Determine the transmission scheme Transmission scheme for the transmission ratio, including the identification and determination of transmission type. 2. Design calculations Transmission structure of each level of design and calculation, generally include: transmission ratio of the distribution, kinematics and dynamics calculation of transmission, transmission parts of the design, calculation and check of the design axis, the axis of the selection and calculation, and calculation of key connectivity options , cabinet design, lubrication and sealing selection and transmission of attachment descriptions. 3. Assembly drawing and the design of the part drawing. Through this design, known planetary gear reducer has a compact, small, compact and feature transmission efficiency, but because of planetary gear reducer transmission ratio, torque to gear structure than other small, self-locking planetary gear reducer Great angle and poor only retreat is not suitable for starting. ?
