基于MATLAB的滚柱活齿传动滑动特性研究

Research on sliding characteristics of eccentric cam roller movable toothtransmission based on MATLAB

滚柱活齿传动的接触副由两个高副和一个低副组成,高副由于接触点的切向速度不同而产生相对滑动。基于滚柱活齿传动的结构特点和工作原理推导出滚柱活齿的运动学模型和滑动模型,并提出了一种基于速度分解原理的滚柱活齿传动新的数值建模方法。研究了设计参数对滑动率和滑滚比的影响,结果表明,随着活齿转角增大滑滚比先减少再增加,对于参数研究,滑动比随着激波器半径和传动比增加而增加,随着活齿半径和偏心距的增加而减少。传动比和滚柱活齿半径的变化对滑滚比的影响较小,偏心距和激波器半径的变化对滑滚比有较大影响。研究结果为减少摩擦和提高滚柱活齿的传动效率提供了理论指导。

The contact of the roller-tooth transmission is composed of two high sidewalks and a low vice.The high vice is relatively sliding from the different cut speed of the contact point.Based on the structural characteristics and working principles of rolling living tooth transmission,this article derives the sports model and sliding model of rolling living teeth,and proposes a new numerical modeling method based on the principle of speed decomposition.The effects of design parameters on the sliding rate and slippery ratio,the results show that as the rolling rolling ratio of the living teeth increases,the ratio of slippery roller is reduced first.For parameter research,the sliding ratio is increased with the ride radius and transmission ratio of the rumor.Increase,decrease with the increase of the radius and eccentric spacing of the living tooth.The changes in the transmission ratio and the radius of the roller teeth are less impact on the slip ratio,and the changes in the eccentric spacing and the radius of the rotor have a greater impact on the slippery ratio.The results of the research provide theoretical guidance to reduce friction and improve the driving efficiency of rolling living teeth.
