Abstract
The utility model discloses an automatic clutching geared down motor, which integrates motor, reducer and clutch together. The utility model is essentially characterized in that: the last step of output gear of the reducer is coated on the output shaft; a compression spring which can presses out the T-shaped wedge iron is arranged in the central hole of the output shaft; and the left ends of the output gear and the output shaft are respectively provided with tooth slot and combining slot for the wedge iron. The magnetclutch is positioned at the left end of the output shaft, and the motive iron core of the magnetclutch is closely contacted with the left end face of the wedge iron. The utility model has simple structure, convenient usage and steady working condition; and the utility model can simplify the design of manually operated mechanism of the load switch and the breaker, and reduce the movement moment of the manually operated mechanism, really practical.
Description
Technical field:
The utility model relates to a kind of automatic clutch gearmotor that is used for operating means such as on-load switch, loop-network switch cabinet, vacuum circuit-breaker, air circuit.
Background technology:
Be used for the necessary slow-speed of revolution of motor of electric equipments such as circuit breaker, on-load switch, loop-network switch cabinet, high moment of torsion,,, improve the output torque to reduce the rotating speed of motor so this class motor all should have decelerator.Existing device by motor and gear reduction unit combination, though can satisfy operating means such as on-load switch, circuit breaker, reach the similar required transmission requirement of occasion that requires, but do not consider the clutch problem between output shaft and motor, decelerator, and electric equipment such as on-load switch, circuit breaker all requires to have manual-operating mechanism when reality is used, use when power failure, maintenance and the abnormal condition to satisfy, cause manual-operating mechanism design component difficulty big, use inconvenience, working life is short.
Summary of the invention:
Goal of the invention of the present utility model is when solving motor operation and the automatic clutch problem of decelerator.Provide a kind of when electric equipments such as on-load switch, circuit breaker in improper operating mode, when promptly using manual operation also can be automatically separate with decelerator, and simple in structure with motor, working stability is reliable, the automatic clutch gearmotor of long service life.
The utility model comprises decelerator (2), elementary motor that is connected (1) and electromagnetic clutch (3) with decelerator (2), decelerator (2) not output gear (4) sky of level is enclosed within on the output shaft (5), be provided with in the interstitial hole of output shaft (5) and can eject the spring (6) of carving iron (7), carving iron (7) is " T " font, be positioned at the teeth groove of output gear (4) left end, output shaft (5) left end is provided with and carves the engaging groove of iron (7) coupling, and the moving iron core (8) of electromagnetic clutch (3) fits with the left side of carving iron (7).The teeth groove of said output gear (4) left side can be established four altogether, and is relative in twos, just is being " ten " font.The engaging groove of said output shaft (5) left end is provided with two on same straight line.
The utility model is in aggregates with motor, decelerator and clutch organic assembling, can separate with decelerator with motor automatically during at on-load switch, circuit breaker etc. in manual operation, thereby simplified the design of the manual-operating mechanism of on-load switch, circuit breaker etc., reduced the action moment of manual-operating mechanism greatly, and the utility model is simple in structure, operating mode is stable, and is easy to maintenance, long service life.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the end view of Fig. 1.
Accompanying drawing 3 is for being iron and the output gear released state schematic diagram carved of the present utility model.
Accompanying drawing 4 is for being iron and the output gear closure state schematic diagram carved of the present utility model.
Embodiment:
Motor of the present utility model (1) is small-power DC motor or series-wound motor.Decelerator (2) is the level Four cylinder gear speed reducer, and elementary and motor (1) link, and Ji output gear (4) sky is not enclosed within on the output shaft (5), and by electromagnetic clutch (3), carve iron (7) and output shaft (5) links.The left part axial centre of output shaft (5) has interstitial hole, is provided with spring (6) in the hole, and the left end of spring (6) withstands " T " font and carves iron (7).Output shaft (5) left end also has and can hold the in-line engaging groove of carving iron (7), and the left end of output gear (4) has and can hold the cross recess of carving iron (7), or offers the straight trough of multiple intersecting angles such as " rice " font as required.Electromagnetic clutch (3) is positioned at the left end of output shaft (5), and the moving iron core (8) of electromagnetic clutch (3) is pushed down the left side of carving iron (7).When electric operatings such as on-load switch, circuit breaker, the work of switching on simultaneously of electromagnetic clutch (3) and motor (1), the moving iron core (8) of electromagnetic clutch moves right to push down under the action of a magnetic field carves iron (7).Carve iron (7) and enter decelerator simultaneously not in the teeth groove and the link slot of output shaft (5) of level output gear (4), drive output gear (4) and rotate the mechanical output of output motor.After electric operating finishes, electromagnetic clutch (3) and motor (1) be dead electricity simultaneously, the moving iron core (8) of electromagnetic clutch and carve iron (7) and under the effect of spring (6), reset, output shaft (5) and gear reduction unit not level output gear (4) are removed the interlock state that pins, at this moment, the manual-operating mechanism of on-load switch, circuit breaker etc. is done manual operation, only drives output shaft (5) rotation, and irrelevant with the motor (1) and the decelerator (2) of front end.
Claims (3)
1, a kind of automatic clutch gearmotor, comprise decelerator (2), elementary motor that is connected (1) and electromagnetic clutch (3) with decelerator (2), it is characterized by decelerator (2) not the level output gear (4) sky be enclosed within on the output shaft (5), be provided with in the interstitial hole of output shaft (5) and can eject the spring (6) of carving iron (7), carving iron (7) is " T " font, is positioned at the teeth groove of output gear (4) left end.Output shaft (5) left end is provided with and carves the engaging groove of iron (7) coupling, and electromagnetic clutch (3) is positioned at the left end of output shaft (5), and the moving iron core (8) of electromagnetic clutch (3) fits with the left side of carving iron (7).
2, by the described a kind of automatic clutch gearmotor of claim 1, the teeth groove that it is characterized by said output gear (4) left end is established four altogether, and is relative in twos, just is being " ten " font.
3,, it is characterized by the engaging groove of said output shaft (5) left end by the described a kind of automatic clutch gearmotor of claim 1.On same straight line, be provided with two.
