摘要
为选取最优的行星离心式无级传动装置偏心曲线轨道,通过模拟计算与试验验证相结合,探讨滑块沿椭圆、余弦曲线和摆线轨道运动时,滑块对曲线轨道的作用力的影响因素,包括滑块转速、偏心率和曲线形式等。研究发现:1)滑块转速越快、偏心率越大,偏心力也越大;2)当滑块转速和轨道偏心率一定时,摆线轨道产生的偏心力最大,椭圆与余弦曲线轨道产生的偏心力接近;3)滑块在余弦轨道运转最平顺,当轨道偏心率为19.3%,滑块转速为1200 r/min时,4个0.5 kg的滑块对余弦轨道的作用力平均值可达100 N。滑块对曲线轨道作用力的平均值主要反映系统传递动力的能力,变化幅度则在一定程度上反映滑块的运行平顺性,在优选偏心曲线轨道时应综合考虑。
In order to select the optimal eccentric curve track of planetary centrifugal stepless transmission device,by combining simulation calculation with experimental verification,the influence factors of the slider’s acting force on the curve track by the slider’s rotating speed,eccentricity and curve form when the slider moves along the ellipse,cosine and cycloid tracks were discussed.Findings:1)The faster the slider rotation speed and the larger the eccentricity,the larger the eccentricity force.2)When the rotating speed of the slider and the eccentricity of the track are constant,the eccentric force generated by the cycloid track is the largest,and the eccentric force generated by the ellipse and cosine curve track is close.3)The slider runs smoothly on the cosine track.When the track eccentricity is 19.3%and the slider speed is 1200 r/min,the average force of four 0.5 kg sliders on the cosine track can reach 100 N.The average value of the force exerted by the slider on the curved track mainly reflects the power transmission ability of the system,while the variation amplitude reflects the running smoothness of the slider to a certain extent,which should be considered comprehensively when optimizing the eccentric curved tracks.
