摘要

以自行设计的液压压紧式牵引传动装置为基础

针对装置传动过程中的自旋功率损失和滑动功率损失进行了理论研究

结合弹流润滑理论对内、外摩擦副的牵引特性进行了数学建模

并通过多重网格方法进行了联合求解

从而获得了系统的传动效率及其变化规律.研究结果表明:液压压紧式牵引传动装置具有转速高、功率大的传动特性

通过控制液压压紧力

可使传动装置的传动效率达到95.5%以上; 自旋功率损失随着传动比的增加呈现出先减后增的变化规律

滑动功率损失随着传动比的增加而减小

当传动比大于0.5时

滑动功率损失趋于稳定; 系统的效率随着传动比的增加呈现出先减后增的变化过程.

Abstract

A hydraulic clamp type traction transmission device was fabricated to theoretically investigate the spin power loss and the sliding power loss during transmission. The mathematical model of the internal and external friction traction characteristics was established with the EHL theory. The internal and external friction EHL equation was jointly solved by the multi-grid method

and the transmission efficiency of the system and its variation were achieved. The results show that the hydraulic clamp type traction transmission device has a transmission character of high speed and high power. The transmission efficiency of continuously variable transmission in the whole ratio range can be above 95.5% by controlling the hydraulic clamp force. The spin power loss decreases first and then increases with an increase in the transmission ratio. The sliding power loss decreases with an increase in the transmission ratio

and it tends to be stable when the transmission ratio is greater than 0.5. These results indicate that the transmission efficiency decreases first and then increases with an increase in the transmission ratio.
