Description
Technical field
The present invention relates to technical field of motors, refer specifically to a kind of attachment device of motor and oil pump.
Background technology
Usual oil pump needs could run well under the driving effect of motor, and connection relation is excellent between oil pump and motor
The bad working efficiency and service life for directly influencing oil pump and motor.
Between oil pump and motor common connection type it is general there are three types of, wherein the first is to add the output shaft of motor
It is long, it stretches into oil pump, the axis for making motor shaft be linked into one with oil pump shaft, second is to lengthen the input shaft of oil pump, is stretched into
In motor, the axis for making oil pump shaft be linked into one with motor shaft, both connection types are required for lengthening on the axis of junction, and one
The axis of aspect, lengthening rigidly decreases, and traveling comfort declines after motor being caused to be connect with oil pump, and failure rate increases；
On the other hand, the specification of general-purpose machine and oil pump is all certain, if desired carries out lengthening the special processing customization of needs to its axis,
Not only high processing costs, and the poor universality of the motor of custom-made or oil pump are not easy to safeguard and repair.
The third connection type between oil pump and motor is to make the power input shaft of oil pump in motor by spline knot
Structure and motor axis connection, it is although simple to operation using this kind of connection type, but due to the power input shaft and motor of oil pump
There is no security measure between axis, and there are gaps between the tooth and tooth of spline, will produce when motor drives oil pump to run at high speed
Strong vibrations not only increase running noise, and the rubbing action between spline tooth and tooth also reduces motor and oil pump
Between the reliability that connects, influence equipment traveling comfort.
In addition, when being attached oil pump and motor using the above attachment device, oil pump and the countershaft of motor and the rank of axis
It connects and is difficult to dock accurately, seriously affected the alignment being connected between oil pump and motor, further reduced the flat of equipment operation
Stability；And docked oil pump with axis with the axis of motor using shaft coupling, equipment expenditure is not only increased, oil pump and motor
Junction is exposed in air for a long time, is also inevitably infected with dust and other impurities, increases the maintenance cost of equipment；And
And the connection type between the above motor and oil pump is complicated, it is difficult to realize the dismounting and replacement of motor or oil pump.
Therefore, for the attachment device between current motor and oil pump, it is badly in need of further improved.
