The switching of gear, because not needing interrupting input power, significantly increase the convenience of operation and cause remote control
Become possible to.The quantity of described O-shaped packing ring 12 is 6.The sealing effectiveness of equipment can be improved.
Operation principle：When swivel joint 1 is passed through pressure air or hydraulic oil, pressure air or hydraulic oil are defeated into power taking
Gap between shaft 2 and O-shaped packing ring 12, due to the sealing function of O-shaped packing ring 12, the pressure air or hydraulic pressure being continually fed into
Oil will push directly on 10 groups of 14 pressing friction piece of piston, the moment of torsion of power taking output gear 6 is transferred into drum 7, then pass to power taking
Output shaft 2, final power taking output gear 6 and power taking output shaft 2 rotate output torque to working equipment together.
When pressure air or hydraulic oil are cancelled at swivel joint 1, O-shaped packing ring 12 returns to initial bit under the action of the spring
Put（Fig. 1 rightmost sides）, friction plate 10 and steel disc 11 separate each other, the gap of design is remain, due to friction plate 10 and steel disc 11
Separate each other, moment of torsion can not be transmitted, therefore when power taking output gear 6 is rotated, steel disc 11 follows power taking output gear 6 to revolve
Then friction plate 10 is then static, then drum 7 is static, power taking output shaft 2 is static, and final output moment of torsion is zero.Now power taking exports
Gear 6 is dallied by needle bearing 5 on power taking output shaft 2.
