工程机械液压系统采用的胶管接头,一端与液压件(或钢管)连接,另一端与胶管连接。与钢管连接端的形式有卡套式、焊接式、法兰式等(本刊1975年第二期已介绍),下面着重介绍胶管连接端的接头设计计算。一、设计原则1.接头结构设计与胶管尺寸、结构及工作压力有密切关系。一般管径大的(>φ4～51mm),接头设计时着重注意接头的防拔脱能力;小管径接头(<φ16mm)要充分注意其密封性能。因为目前使用的钢丝编织胶管是
The hose joint used in the hydraulic system of the construction machinery is connected to the hydraulic part (or steel pipe) at one end and to the hose at the other end. The form of the connection with the steel pipe is in the form of a ferrule type, a welded type, a flange type, etc. (This issue was introduced in the second issue of the issue in 1975). The following describes the joint design calculation for the connection end of the hose. First, the design principle 1. Joint structure design and hose size, structure and work pressure are closely related. Generally large diameter (>φ4 ~ 51mm), the connector design focuses on the joint’s ability to prevent pull-out; small diameter joints (<φ16mm) should pay full attention to its sealing performance. Because the current wire braid hose is
