The Hydraulic Cylinder with Extensive Position Controlled Piston Rod
Author(s): 
Pages: 21-23
Year: Issue:  4
Journal: Hydraulics Pneumatics & Seals

Keyword:  液压缸位置可控滚珠丝杆副误差分析;
Abstract: 该文介绍了一种活塞杆伸出量可测并可控的液压缸.该缸利用滚珠丝杆将活塞杆的直线位移转化为丝杆角位移的方法进行位置测量,其结果由光栅编码器输出并传送到控制中心,由控制中心控制伺服阀的阀口方向和开口大小,从而对液压缸活塞杆产生控制作用.本文对其原理进行了阐述,并对可能存在的测量误差进行了分析.
