The utility model discloses can conveniently adjust the relative position of oil pump and motor to can adjust the axiality of oil pump and motor.
Description
Technical field
The utility model belongs to hydraulic driving field, specifically the motor pump combination unit of the adjustable coaxality of a kind of hydraulic system.
Background technique
In hydraulic driving system, if oily Pump and Electromotor disalignment, then the mechanical efficiency of oil pump can be made to reduce and to produce very large noise simultaneously, and accelerate the loss of oil pump and motor, the working life of both shortenings.Because the seam positioning precision of current motor is not high, the rotor disalignment of seam and motor, adopts conventional motor and the compound mode of oil pump, can cause oily Pump and Electromotor disalignment, and position is therebetween not easy to regulate.
Based on this, special proposition the utility model.
Summary of the invention
In order to solve the above-mentioned technical problem that prior art exists, the utility model provides the motor pump combination unit of the adjustable coaxality of a kind of hydraulic system, can prevent the generation of motor and oil pump disalignment phenomenon.
The technical solution of the utility model is as follows:
The motor pump combination unit of the adjustable coaxality of a kind of hydraulic system, comprise base, motor, coupling, oil pump, electric machine support and oil pump bracket, motor and oil pump are separately fixed on respective support, two stands is bolted on base, and oil pump bracket is provided with multiple adjustment tapped hole and adjustment screw.
Further, described oil pump bracket comprises the level board upright plate vertical with level board with, between level board and upright plate, there are two three-support plates, described level board arranged multiple unthreaded hole and multiple adjustment tapped hole, described upright plate is arranged an axis hole and multiple unthreaded hole.Unthreaded hole on level board is used for the bolt through connecting, and adjustment tapped hole is used for being screwed into adjustment screw; Axis hole on upright plate is used for holding and passing through oil pump shaft, and the unthreaded hole on it is used for the bolt through connecting.
Further, described adjustment tapped hole has four, is distributed in the outside of unthreaded hole on described level board between two.
Further, the unthreaded hole diameter on described level board is greater than the diameter through the bolt in it.There are some small―gap suture between such level board and the bolt be connected, thus position relationship therebetween can be finely tuned, conveniently oily Pump and Electromotor is fine-tuning to coaxial state.
Advantage of the present utility model is as follows: on oil pump bracket, 1, arrange multiple tune tapped hole and adjustment screw, can adjust oil pump position in the height direction; 2, the unthreaded hole diameter on oil pump bracket, slightly larger than the diameter of connecting bolt, can finely tune oil pump position in the horizontal direction.

Embodiment
Below in conjunction with attached Fig. 1 and 2, the motor pump combination unit of the adjustable coaxality of the utility model hydraulic system is further described.
As shown in Figure 1, the motor pump combination unit of the adjustable coaxality of hydraulic system comprises base 1, motor 2, coupling 3, oil pump 4, electric machine support 5 and oil pump bracket 6, motor 2 and oil pump 4 are separately fixed on respective support (5,6), two stands (5,6) is bolted on base 1, and oil pump bracket 6 is provided with multiple adjustment tapped hole 611 and adjustment screw 7.Base 1 is arranged on vibration damper 8.
Oil pump bracket 6 comprises a level board 61 upright plate 62 vertical with level board 61 with, two three-support plates 63 are had between level board 61 and upright plate 62, described level board 61 is arranged multiple unthreaded hole 612 and multiple adjustment tapped hole 611, described upright plate 62 is arranged an axis hole 621 and multiple unthreaded hole 622.Unthreaded hole 612 on level board, for through the bolt connected, adjusts tapped hole 611 for being screwed into adjustment screw 7; Axis hole 621 on upright plate 62 is for holding and passing through oil pump shaft, and the unthreaded hole 622 on it is for the bolt through connection.
In one embodiment, adjustment tapped hole 611 is 4, is distributed in the outside of the unthreaded hole 612 on level board between two.
In one embodiment, unthreaded hole 612 diameter on level board 61 is greater than the diameter through the bolt in it.There are some small―gap suture between such level board 61 and the bolt be connected, thus position relationship therebetween can be finely tuned, conveniently oil pump 4 and motor 2 are fine-tuning to coaxial state.
Embody rule process of the present utility model is as follows: the adjustment of the coaxality of motor 2 and oil pump 4, is to realize relative to the position of base 1 by rotating adjusting screw 7 thus adjusting oil pump bracket 6.Adjustment tapped hole 611 on oil pump bracket 6 level board 61 does not have corresponding hole on base 1, regulates oil pump bracket 6 relative to the vertical position of base thus adjustment oil pump 4 and motor 2 coaxality in the vertical direction by turning adjusting screw 7; Unthreaded hole 612 diameter on level board 61 is slightly larger than the diameter of fixing bolt, certain gap is had between such unthreaded hole 612 and bolt shank, can adjust the horizontal position of oil pump bracket 6 relative to base 1, thus the coaxality achieving the substantially horizontal of oil pump 4 and motor 2 regulates.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the present utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
