东方红-60T推土机旧式油缸活塞杆导向套用三瓣爪或压盖定位。新式油缸活塞杆导向套改为卡簧定位:油缸内径和导向套外径均有卡簧槽,为了便于拆装,油缸上对正卡簧槽处有与槽相通的弧形开口;导向套上有卡簧爪孔;卡簧一端有爪,另一端有拔梢。安装时,将导向套装入油缸,转动导向套,当导向套卡簧爪孔与油缸弧形开口对正时,把卡簧爪插入导向套孔,再转动导向套,使卡簧进入油缸与导向套卡簧槽内。导向套可右转,也可左转。若右转,卡簧拔梢端应在左;若左转,卡簧拔梢端应在右。拆卸、安装时导向套若是右转,拆卸时就应左转,转动时拔梢端便可从油缸弧形开口处退出,不易退出时,可用有尖的合适铁钉等引导。当转至导向套卡簧爪孔与弧形开口对正时,可将卡簧取下,最后取出导向套。新式油缸拆装简化了。但由于卡簧质量差、或对结构不了解、或拆装不得要领,卡簧爪折断便成了常见的故障。卡簧爪折断后,转动导向套时,卡簧不随着转动,卡簧无法退出。这时,可用钻钻断;无钻时,可将三
Dongfanghong -60T bulldozer old-style cylinder piston rod guide sleeve with three claws or gland positioning. The new cylinder piston rod guide sleeve into the retainer positioning: cylinder diameter and guide sleeve outer diameter have spring groove, in order to facilitate the disassembly, the cylinder on the positive snap spring groove has an arc-shaped opening communicating with the groove; guide sleeve Have a spring claw hole; retainer claw at one end, the other end of the tip. When installing, insert the guide sleeve into the oil cylinder and turn the guide sleeve. When the guide sleeve snap claw hole is aligned with the cylinder arc opening, insert the snap claw into the guide sleeve hole and turn the guide sleeve to make the circlip enter into the cylinder and guide Retaining card spring groove. Guide sleeve can turn right, but also turn left. If turn right, pull the spring should be left; if left turn, pull the spring should be in the right. When the guide sleeve is removed and installed, if the guide sleeve is turned right, turn left when dismounting, withdraw from the curved opening of the cylinder when turning, and guide with suitable nails with pointed tip when it is not easy to exit. When you turn to the guide sleeve Retaining Pawl hole and arcuate opening alignment, the card spring can be removed, and finally remove the guide sleeve. New cylinder disassembly simplified. However, due to poor quality retainer, or do not understand the structure, or disassembly can not get essentials, snap claw broken it has become a common fault. After the claw claw is broken, when turning the guide sleeve, the circlip does not rotate with the circlip, and the circlip can not exit. At this time, available drilling off; no drilling, can be three
