液压缸缸体与缸盖的连接型式常见的有螺纹连接、法兰及拉杆连接、法兰及螺栓连接、卡环连接等几种。对于大口径液压缸,如采用螺纹连接,其配合处易产生锈死或咬死现象;而在高压和液压缸径向尺寸较小的情况下,法兰连接也是不宜选用的。因此,在大吨位液压缸设计中,常采用卡环连接的结构。卡环连接装拆方便,强度大,在相同压力下,其径向尺寸较其它连接型 Cylinder cylinder head and cylinder head connection common thread connections, flange and tie rod connection, flange and bolt connections, snap ring connections and several other. For large-diameter hydraulic cylinder, such as the use of threaded connections, with the Department prone to rust or killed; and in the case of high-pressure and small hydraulic cylinder size, the flange connection is not suitable for use. Therefore, large-tonnage hydraulic cylinder design, often used snap ring structure. Snap ring assembly and disassembly convenience, strength, under the same pressure, the radial size than other connection type
