Description
Technical field
The present invention relates to water pump fields, and in particular to pump motor protects equipment with output shaft.
Background technique
Water pump is the machinery for conveying liquid or being pressurized liquid.It transmits the mechanical energy of prime mover or other external energies
To liquid, increase liquid energy, is mainly used to convey liquid to include water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid gold
Belong to etc..Water pump also can transport liquid, admixture of gas and the liquid containing suspended solids.The technical parameter of pump performance has stream
Amount, suction, lift, shaft power, water power, efficiency etc..Water pump can be divided into volume water pump, vane pump according to different working principles
Etc. types.Positive displacement pump is to transmit energy using the variation of its swept volume of a single chamber；Vane pump is the phase using rotary vane and water
Energy is transmitted in interaction, there is a types such as centrifugal pump, axial-flow pump and mixed-flow pump.
The pump shaft of water pump and the output axis connection of motor, the output shaft rotation of motor, and pump shaft is driven to rotate, then drive
The pump leaf of water pump is rotated around the axis of pump shaft.When pumping the leaf fluid blockage to be driven inside pipeline, motor output shaft
The load born becomes larger, and the one end of the output shaft of motor far from water pump continues to turn according to predetermined direction under the influence of a magnetic field
It is dynamic, two contrary torques are then generated at the both ends of output shaft, when blocking is serious inside pipeline, motor output shaft quilt
It twists off.
Summary of the invention
It is an object of that present invention to provide pump motor output shafts to protect equipment, solves when the pump leaf fluid to be driven is stifled
When plug is inside pipeline, the both ends of meeting motor output shaft generate two contrary torques, then will lead to motor output shaft
The problem of being twisted off.
The present invention is achieved through the following technical solutions:
Pump motor protects equipment with output shaft, including the decelerating motor and water pump being installed on bottom plate, the deceleration
The output shaft I of motor is connect with the pump shaft of water pump, and mounting groove is provided on the upper surface of the bottom plate, and the mounting groove prolongs
It stretches direction perpendicular to the axis of output shaft I, close to one end of output shaft I is closed end on mounting groove, the other end is open end, and
There are two mounting grooves, and is symmetrically disposed on bottom plate along output shaft I；
Be provided with auxiliary-motor in the two sides of the output shaft I, the axis of the output shaft II of the auxiliary-motor each parallel to
The axis of output shaft I is provided with supporting block in the bottom of auxiliary-motor, and the supporting block and mounting groove cooperate；
Side on output shaft I close to water pump is socketed with driven gear, is socketed with driving gear on output shaft II,
Driven gear is engaged with driving gear, and II rotation direction of output shaft of two auxiliary-motors is identical, and the rotation direction phase with output shaft I
Instead；
Auxiliary-motor is bolted on bottom plate.
According to actual use operating condition, whether selectivity is mounted on auxiliary-motor on bottom plate, so that driven gear and driving tooth
Wheel engagement.
When operating condition is harsh, driven gear is engaged with driving gear, then starts decelerating motor and auxiliary-motor, so that output
Axis I and two output shaft II rotates, and II rotation direction of output shaft of two auxiliary-motors is identical and oppositely oriented with output shaft I.When
When pumping the leaf fluid blockage to be driven inside pipeline, two auxiliary-motors pass through corresponding driving gear and driven gear pair
Output shaft I increases by two thrusts, offsets the torque that a part is generated by line clogging, then to improve the same of I both ends of output shaft
Step property, the case where then preventing motor output shaft from being twisted off appearance.
Further, the mounting groove is dovetail groove, and opening size is less than slot bottom size, the cross section of the supporting block
Size is consistent with the cross sectional dimensions of mounting groove.
Auxiliary-motor is not only bolted on bottom plate, also limited perpendicular to the direction of bottom plate by dovetail groove
Position, the situation that reducing the vibration generated when motor work causes bolt thread impaired occur, protect on bolt and bottom plate
Screw thread.
Compared with prior art, the present invention having the following advantages and benefits:
1, pump motor of the present invention protects equipment with output shaft, and two auxiliary-motors are by corresponding driving gear and passively
Gear mesh output shaft I increases by two thrusts, offsets the torque that a part is generated by line clogging, then to improve I liang of output shaft
The synchronism at end, the case where then preventing motor output shaft from being twisted off appearance；
2, pump motor of the present invention protects equipment with output shaft, and auxiliary-motor is not only bolted on bottom plate, also logical
Dovetail groove is crossed limited perpendicular to the direction of bottom plate, reduce the vibration generated when motor work cause bolt thread by
The case where damage, occurs, and protects the screw thread on bolt and bottom plate.
