Cylinder pressure, including rotary main shaft, spindle jacket is provided with the connecting cylinder being sequentially connected with, rear cup, cylinder barrel
With front cup, main shaft one end is connected with connection screw sleeve after connecting cylinder, and the main shaft other end passes protecgulum
Connecting after Tong has flange, described inner wall of cylinder to be vertically installed with stator blade, and spindle outer wall is vertically installed with
Moving vane, stator blade and moving vane are interspersed, and the cavity between cylinder barrel and cylinder barrel forms oil pocket；Described master
Outer shaft sleeve is provided with some interior rotatory sealing, and interior rotatory sealing corresponds respectively to rear cup and front cup is arranged, institute
Stating spindle jacket and be provided with some fairleads, fairlead corresponds respectively to rear cup and front cup is arranged, described master
Outer shaft sleeve is provided with some dust plugs, and dust plug is positioned at outside fairlead, and interior rotation sealing position is in dust plug and leads
Between set；Being provided with photoelectric encoder and electrohydraulic servo valve on described connecting cylinder, electrohydraulic servo valve is by pipe
Road forms loop with oil-out and the oil-in of cylinder barrel, and photoelectric encoder connects flexible axle, elastic shaft and company
Connect the fixing connection of screw sleeve.
Further, connect between described photoelectric encoder and elastic shaft and have shaft coupling.
Further, described elastic shaft fixes connection by taper bolt with being connected screw sleeve.
The beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, easy and simple to handle,
By photoelectric encoder and the work of electrohydraulic servo valve, directly oil pressure is converted into oscillating motion, it is not necessary to extra
Drive mechanism, have that compact conformation, mechanical efficiency be high, moment of torsion output steadily, the advantages such as handling is good.
