Abstract
The utility model discloses a motor for an electric hydraulic pusher, which comprises a rotor, a stator, a rotor shaft, a bearing and an end cap. The rotor is arranged on the rotor shaft, one end of the rotor shaft is connected with an on oil pump shaft of the hydraulic pusher, the end surface of the rotor shaft which is connected with the oil pump shaft of the hydraulic pusher is provided with a recess, and the recess is provided with a key slot. The recess of the rotor shaft of the motor for an electric hydraulic pusher is provided with the key slot so that a motor coupler, a pump coupler, a motor seat, an elastic quincuncial rubber ring and the like can be omitted when the rotor shaft is connected with the oil pump shaft of the hydraulic pusher. The motor for an electric hydraulic pusher is more compact in structure, reduces the volume of the electric hydraulic pusher, brings more convenience for transport and installation, and simultaneously reduces production and manufacturing costs.
Description
Technical field:
The utility model relates to a kind of motor, relates in particular to a kind of Electrohydraulic push rod motor.
Background technology:
Electrohydraulic push rod is power source with the motor, by motor just (instead) make hydraulic oil pass through the two-way oil pump pressure oil output to rotation, through the oil circuit integrated valve block, deliver to operating cylinder, realize the reciprocating motion of piston rod.What the motor of conventional type Electrohydraulic push rod and oil pump adopted is the shaft coupling connected mode.The motor energising, motor shaft rotates, and motor shaft is connected with motor coupler by key, the drive motor coupler rotates, and motor coupler drives the pump shaft coupling by elasticity plum blossom rubber ring and rotates, and the pump shaft coupling is by the key effect, the drive oil pump shaft rotates, and then drives oil pump work.The Electrohydraulic push rod complex structure, volume is big, manufacturing cost is high.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of simple and practical, volume is little, compact conformation, Electrohydraulic push rod motor that manufacturing cost is low.
The utility model Electrohydraulic push rod with the motor technology scheme is:
The Electrohydraulic push rod motor, comprise rotor, stator, armature spindle, bearing and end cap, described rotor is arranged on the armature spindle, one end of described armature spindle is connected with the oil pump shaft of hydraulic push rod, described armature spindle is provided with shrinkage pool with the end face that the oil pump shaft of hydraulic push rod is connected, and described shrinkage pool is furnished with keyway.
Described keyway is the flat key groove.
The utility model Electrohydraulic push rod motor, the armature spindle of motor with directly be connected with the oil pump shaft of hydraulic push rod, keyway is joined in perforate in armature spindle, oil pump shaft inserts in the rotor shaft hatch, is connected to each other by flat key, works as electrical power, armature spindle rotates, armature spindle directly drives oil pump shaft and rotates by being connected with the flat key of oil pump shaft, and then drives oil pump work.
The utility model has the advantages that: keyway is joined in perforate in armature spindle, has saved motor coupler, the pump shaft coupling, motor cabinet, parts such as elasticity plum blossom rubber ring, structure is compact more, dwindle the volume of Electrohydraulic push rod, made transportation easier for installation, reduced manufacturing cost simultaneously.
