Specifically, first connector is rotor connector, and the second connector is power input shaft connector.
The present invention also provides a kind of slide block type eccentric gearing screw pump, between the rotor and transmission shaft that solve existing screw pump
Connected by universal joint, cause that overall structure is long, fragile sealing shroud, and universal joint both ends are there are the swing of malalignment,
The problem of causing output medium unstable.
The technical solution adopted by the present invention is：Slide block type eccentric gearing screw pump, including motor, speed changer, shaft coupling, axis
Bearing and casing, motor are connected to the side of shaft coupling by speed changer, and the opposite side of shaft coupling is connected to bearing block, bearing block
Built-in transmission shaft, casing is interior to set stator and rotor, and the both sides of casing form suction room and discharge room respectively；Transmission shaft and rotor
Between be connected by any one above-mentioned slide block type radial gear, wherein be fixedly connected between the first connector and stator,
It is fixedly connected between second connector and transmission shaft.
It is further：Slide block type eccentric gearing screw pump further includes base, and motor, speed changer, bearing block and casing are equal
It is fixedly installed on base.
The beneficial effects of the invention are as follows：Pass through between the first connector and the second connector of slide block type radial gear
Sliding block is sequentially connected, and compared to the connection mode of universal joint, overall structure length is shorter；During use, if the first connector
With the axial direction of the second connector not on the same line, tune can be moved up and down between sliding block and the first connector, the second connector
Whole center, ensures that transmission device rotates passing power on the same line, ensures that transmission device is stably run.
It is connected between the transmission shaft and rotor of slide block type eccentric gearing screw pump by slide block type radial gear, it is axial
Size is obviously shortened, and with respect to the screw pump of link-type universal joint connection, similar model shortens 3/5.Slide block type eccentric gearing
For the transmission shaft and rotor of screw pump not in same axis, sliding block and the first connector, the second connector will move up and down adjustment
Center, ensures transmission shaft and rotor rotates on the same line and passing power, does not have since sliding block is limited by sliding sleeve bearing
Axial movement, makes rotor be maintained at former section rotation, ensures smoothly output medium.
