Description
Technical field
The utility model relates to motor and oil pump connection technique field, more particularly, relates to the device of a kind of motor and oil pump integrated.
Background technique
At present, motor is generally by flat key band coupling connection (shown in Figure 1) or by inside and outside splined (shown in Figure 2) with connecting of oil pump.
Flat key connects need to use motor fixing seat 11 and coupling 12, and coupling 12 is built in motor fixing seat 11 inside, for connecting motor 13 and oil pump 14.For ensureing that motor shaft 131, coupling 12 and oil pump shaft 141 reach close-fitting requirement, flat key connects has relatively high expectations to the assembly precision of each parts, thereby assembling difficulty is larger.Although motor 21 is simple by splined assembling with oil pump 22,, the manufacturing process complexity of interior external splines, and can cause spline wearing and tearing after long-time use, thus affect the reliability of transmission.
In summary, how to provide the device of a kind of motor and oil pump integrated to make motor and oil pump assemble technical problem simple and that the those skilled in the art of being not easy to wear are urgently to be resolved hurrily.
Model utility content
In view of this, the utility model provides the device of a kind of motor and oil pump integrated, to realize the simple assembling between motor and oil pump, solves the wearing and tearing that are connected between motor and oil pump simultaneously.
A device for motor and oil pump integrated, comprising:
Motor and oil pump, the motor shaft in described motor and the oil pump shaft of described oil pump are same rotating shaft, described rotating shaft is connected as being integrated between coupling shaft and described motor, described oil pump.
Preferably, the front cover of described motor and the front cover of described oil pump are same front cover, and described same front cover is as the compatible front-end lid of described motor and described oil pump.
Preferably, described compatible front-end lid is aluminum alloy material.
Preferably, described compatible front-end lid is cast steel.
Preferably, described compatible front-end lid is connected with the outer ring of the fore bearing of described motor.
Preferably, described rotating shaft is high carbon steel material.
Preferably, described rotating shaft is stainless steel.
Preferably, the pump core adaptation of the connection part of described rotating shaft and described oil pump and described oil pump.
Can find out from above-mentioned technological scheme, the utility model provides the device of a kind of motor and oil pump integrated, comprise motor and oil pump, the motor shaft in motor and the oil pump shaft of oil pump are same rotating shaft, and this rotating shaft is connected as being integrated between coupling shaft and motor, oil pump.The utility model is by making motor and oil pump share a rotating shaft, realize the integrated design of motor and oil pump, not only assembling is simple, and the wearing and tearing that are connected between motor and oil pump are solved, ensure the concentricity of motor and oil pump, thereby improved the working life of reliability and the whole control system of transmission, very big minimizing installed the cost of producing, safeguarding aspect.
