二级转速控制液压变速器的应用

Application of the Hydraulic Transmission Controlled by Second-Stage Rotating Speed

由力士乐公司生产的二级转速控制液压变速器采用变量泵——变量马达闭式回路的二级调节系统,首次成功地应用在国内的直升机旋翼机身组合模型吹风试验台上,被证明是具有国际先进水平。本文简单介绍了它的工作原理、主要技术数据、结构特点以及调试过程的情况。

Hydrauli transmission controlled by second-stage rotating speed uses variable pump-variable motor dosed circuit for second- stage adjustable system made in Mannesmann Reaxth GmbH, it is successfuly applied to home ZMST and demonstrated on an international scale. This paper simply introduces its working principle, main technical data, structural characteristics and the case of the process of pretest.
