Description
Technical field
The present invention relates to technical field of motors, specifically refer to the jockey of a kind of motor and oil pump.
Background technology
Usual oil pump needs could run well under the driving effect of motor, and between oily Pump and Electromotor, the quality of annexation directly has influence on operating efficiency and the useful life of oily Pump and Electromotor.
Between oil Pump and Electromotor, conventional connected mode generally has three kinds, and wherein, the first is lengthened by the output shaft of motor, stretch in oil pump, make the axle that motor shaft and oil pump shaft are linked into one, the second is lengthened by the power shaft of oil pump, stretches in motor, make the axle that oil pump shaft and motor shaft are linked into one, these two kinds of connected modes all need the axle of junction to lengthen, and on the one hand, the axle rigidity of lengthening decreases, after motor can be caused to be connected with oil pump, traveling comfort declines, and failure rate increases; On the other hand, general-purpose machine and oily pump size are all certain, and if desired carrying out lengthening to its axle needs to process customization specially, and not only processing cost is high, and the poor universality of the motor of custom-made or oil pump, be not easy to maintain and repair methods.
The third connected mode between oil Pump and Electromotor is that the power input shaft of oil pump is connected with motor shaft by spline structure in motor, although adopt this kind of connected mode simple to operation, but owing to there is no security measure between the power input shaft of oil pump and motor shaft, and there is gap between the tooth of spline and tooth, strong vibrations can be produced when driven by motor oil pump runs up, not only increase operating noise, rubbing action between spline tooth with tooth also reduces the reliability be connected between motor with oil pump, affects equipment traveling comfort.
In addition, when using above jockey to be connected by oily Pump and Electromotor, the countershaft of oily Pump and Electromotor was difficult to dock accurately with being connected of axle, had had a strong impact on the alignment be connected between oily Pump and Electromotor, reduce further equipment traveling comfort; And using shaft coupling to be docked with axle by the axle of oily Pump and Electromotor, the equipment that not only increases is paid, and the junction of oily Pump and Electromotor is exposed in air for a long time, also inevitably foreign material such as covered with dust, adds the maintenance cost of equipment; Further, the connected mode between above motor and oil pump is numerous and diverse, is difficult to the dismounting and the replacing that realize motor or oil pump.
Therefore, for the jockey between current motor and oil pump, be badly in need of doing further improvement.
Summary of the invention
Technical problem to be solved by this invention is the present situation for prior art, provide a kind of versatility good, be in transmission connection steadily and the jockey of the motor of easy accessibility and oil pump.
The present invention solves the problems of the technologies described above adopted technical scheme: the jockey of a kind of motor and oil pump, it is characterized in that: comprise the first end cap, the second end cap that are connected with motor and oil pump respectively, the corresponding bindiny mechanism being provided with coupling mutually respectively on described first end cap and the second end cap; The locking device that described motor output shaft and oil pump power shaft can be fastenedly connected is provided with in cavity between described first end cap and the second end cap; Described first end cap or the second end cap also offer the dismounting mouth for locking device described in dismounting.
As preferably, described locking device is arranged in the second end cap, and described dismounting mouth is arranged on the second end cap.
The casing of described motor has screwed hole, described bindiny mechanism is the first through hole, the second through hole that are opened in respectively on the first end cap and the second end cap, this first through hole, the second through hole are corresponding with above-mentioned screwed hole to be arranged, and a bolt is fastenedly connected through described first through hole, the second through hole and screwed hole.Adopt this bindiny mechanism, connect more convenient.
Described first end covers the first oral area having power supply machine output shaft and stretch out, and described second end cap has the second oral area that oil feed pump power shaft stretches out; The installing hole that the oil feed pump power shaft described motor output shaft with an axis inserts, and, the periphery wall of motor output shaft has vertically at least one notch communicated with described installing hole.Wherein, described notch is preferably four, and the circumference along described installing hole is arranged.
Described locking device comprises the first clamp ring and the second clamp ring, described first clamp ring has the through hole that power supply machine output shaft passes, described first clamp ring also has the opening of an axis and the periphery wall of described first clamp ring has extended to form the first taper seat and the second taper seat from centre to both sides, described first taper seat and the less one end of the second taper seat radius are arranged outwardly; Two second clamp rings be set in the first taper seat of described first clamp ring respectively and the second taper seat outer and be bolted connection.When being positioned at the second clamp ring outside the first taper seat and the second taper seat and being undertaken fastening by bolt, opening in first clamp ring reduces gradually under external force fastening effect, notch on motor output shaft also reduces thereupon, thus motor output shaft and oil pump power shaft are firmly linked together, adopt above-mentioned locking device, structure is simple and operation is convenient.
