Description
Technical field
The present invention relates to a kind of decelerator, the permanent magnetic direct current geared motor of particularly a kind of miniaturization.
Background technology
Decelerator is the case integrated device of motor and gear reduction, and it utilizes gear reduction to be the slow-speed of revolution of other rotating shafts by the high transformation of speed of motor rotary shaft, thus the power of the slow-speed of revolution required for exporting, high pulling torque.
Under some application scenario, miniaturized decelerator is absolutely necessary, but for concrete use and installation environment, owing to being subject to the restriction of all many condition, design the miniaturized decelerator not a duck soup meeting these and require.
Low-voltage vacuum switch is exactly a kind of like this device of application scenario, and it had both needed miniaturized decelerator, had extremely harsh requirement again to it.It requires that the technical parameter of this decelerator reaches output speed 12r/min on the one hand, Driving Torque 34N.m: require that again the overall dimension of this decelerator meets the requirement of low-voltage vacuum switch miniaturization on the other hand, and motor must be vertical with the connection of reduction box.
Summary of the invention
The object of this invention is to provide a kind of permanent magnetic direct current geared motor of miniaturization, to meet the requirement of low-voltage vacuum switch to miniaturized decelerator.
The object of the invention is to be achieved through the following technical solutions:
A kind of Miniature permanent magnetic direct current geared motor, comprise permanent magnet direct current motor and gear reduction box, described permanent magnet direct current motor is primarily of rotor, stator, front end housing and rear end cap composition, described front end housing there is the boss concentric with the rotating shaft of described rotor, described gear reduction box is primarily of deceleration box, first-stage worm gear worm gear box, three-stage gear reduction mechanism and gear box cover composition, described deceleration box there is the hole passed through for described rotating shaft, described boss is chimeric with this hole, described deceleration box is closely connected with described front end housing, the rotating shaft of described rotor connects with the worm screw of described first-stage worm gear worm gear box, the pinion of the first order of described three-stage gear reduction mechanism is coaxial with the worm gear of described first-stage worm gear worm gear box, wantonly two axles in the axle at the gear places at different levels of described three-stage gear reduction mechanism are parallel and coplanar in space, the output shaft of described gear reduction box is the axle at the gear wheel place of the third level of described three-stage gear reduction mechanism.
Rotating shaft in described hole is provided with thrust ball bearing.
Beneficial effect of the present invention is: compact conformation, volume are little.

Embodiment
As shown in Figures 1 to 3, Miniature permanent magnetic direct current geared motor of the present invention, comprise permanent magnet direct current motor and gear reduction box, described permanent magnet direct current motor is primarily of rotor 1, stator 2, front end housing 3 and rear end cap 4 form, described front end housing 3 there is the boss concentric with the rotating shaft of described rotor 1, described gear reduction box is primarily of deceleration box 5, first-stage worm gear worm gear box, three-stage gear reduction mechanism and gear box cover 6 form, described deceleration box 5 there is the hole passed through for described rotating shaft, described boss is chimeric with this hole, described deceleration box 5 is closely connected with described front end housing 3, the rotating shaft of described rotor 1 connects with the worm screw 7 of described first-stage worm gear worm gear box, the pinion of the first order of described three-stage gear reduction mechanism is coaxial with the worm gear of described first-stage worm gear worm gear box, wantonly two axles in the axle at the gear places at different levels of described three-stage gear reduction mechanism are parallel and coplanar in space, the output shaft 8 of described gear reduction box is the axle at the gear wheel place of the third level of described three-stage gear reduction mechanism.
Because worm screw can be subject to the effect of a deboost when transmitting torque, and Miniature permanent magnetic direct current geared motor of the present invention needs forward and reverse running, axial endplay is there is due to the change of Impact direction when changing for avoiding worm steering, worm and gear sharply worn and torn and reduces useful life, the rotating shaft in described hole being provided with thrust ball bearing 9.
The course of work of the present invention is: motor operation, the rotating shaft rotated drives the worm screw connected thereon to rotate, worm screw drives worm gear to rotate, complete the primary speed-down of turbine and worm decelerator, the three-stage gear reduction mechanism that the pinion of the first order gear reduction coaxial with worm gear drives power thereafter to transmit step by step, transmission of power is to the enterprising line output of output shaft the most at last.
The present invention is exclusively used in low-voltage vacuum switch, has compact conformation, advantage that volume is little.
