Abstract
The utility model relates to an integrated motor pump, which transmits coaxially and is good in reliability and small in occupied space. The integrated motor pump comprises a motor, a motor end cover is arranged at the front end of the motor, a guiding groove with a spline is arranged inside a motor shaft inside the motor, a gear pump is arranged in the front of the motor, the spline is arranged on a shaft of the gear pump, and a spline shaft on the gear pump is closely connected with the spline in the guiding groove of the motor. The gear pump is fixedly connected with the motor end cover through a bolt. The integrated motor pump has the advantages that the gear pump and the motor end cover are fixedly connected together through the bolt, the motor shaft and the gear pump shaft share the same coaxiality and transmit coaxially, transmission precision is guaranteed, and reliability is good.
Description
Technical field
The utility model relates to the electromechanical industries field, relates in particular to a kind of integral type electric-motor pump.
Background technique
Being in transmission connection between prior motor and the gear pump generally is to adopt belt to be connected or coupling connects, and the connection of this mode makes motor and the reduction of gear pump alignment, the non-constant of reliability, and occupation space is big.
Summary of the invention
The purpose of the utility model provides a kind of same shaft drive, good reliability, the integral type electric-motor pump that takes up room little.
For realizing above-mentioned purpose, the technological scheme that the utility model adopted is:
A kind of integral type electric-motor pump; Comprising: motor, its characteristics are: the Front-end Design of motor has electric motor end cap, is designed with positioning spigot on the electric motor end cap; Motor shaft in the motor is the internal spline formula; The place ahead of motor is designed with gear pump, is designed with external splines on the axle of gear pump, and the splined shaft on the gear pump closely is connected with the interior spline of motor shaft; Gear pump is fixedly connected with electric motor end cap through bolt.
The utility model has the advantages that: gear pump and electric motor end cap in the utility model link together through bolt; Guarantee coaxality through the positioning spigot on gear pump flange and the electric motor end cap; The motor female splined shaft cooperates with the gear pump male splined shaft, has guaranteed transmission accuracy, good reliability.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of integral type electric-motor pump; As shown in Figure 1, comprising: motor 6, the Front-end Design of motor 6 has electric motor end cap positioning spigot 1; Motor shaft in the motor 6 is an internal spline; The place ahead of motor 6 is designed with gear pump 5, and the axle of gear pump 5 is designed to spline, and the splined shaft 3 on the gear pump closely is connected with the positioning spigot of motor 2 interior splines; Gear pump 5 is fixedly connected with electric motor end cap 1 through bolt 4.
The beneficial effect of the utility model is: gear pump and electric motor end cap in the utility model link together through bolt, and flange that the oil hydraulic pump abutting end covers and electric motor end cap positioning spigot precision-fit have been guaranteed the coaxality of motor shaft and hydraulic pump shaft; Save coupling simultaneously, reduced installing space.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and protection domain to the utility model limits; Under the prerequisite that does not break away from the utility model design concept; Common engineers and technicians make the technological scheme of the utility model in related domain various modification and improvement all should fall into the protection domain of the utility model.
