金属推块V-带型CVT的研究Ⅱ——金属推块和环拉伸之间的压缩力

A Study of a Metal pushing V Belt Type CVT——art Ⅱ: Compression Force Between Metal Blocks and Ring Tension

本研究采用超小型测力仪插入两推块和遥测装置之间在几种固定速比下测量主动和从动带轮上推块压缩力分布。同时采用一种特别设计的推块测出了环拉力的分布。从实验结果可以作出以下结论 :( 1 )推块压缩力分布在主动带轮上明显不同于从动带轮。( 2 )环拉力在带的各边不同 ,这种现象由于两带轮间支承面速度不同造成的。

In this study distributions of block compression force on the driving and driven pulleys were measured using a ting load cell inserted between two blocks and a telementer system, under several constant speed ratios. Ring tenison distributions were also measured using a specially devised block. From the experimental results, the following conclusions were drawn: (1) Block compression force distribution on the driving pulley is significantly different from that on the driven pulley. (2) Ring tension takes different value at each side of strings. It is considered that this phenomenon is caused by difference of saddle surface speed between two pulleys.
