Abstract
The invention discloses a speed reduction motor with a clutch function. The speed reduction motor comprises a motor body assembly and a speed reduction apparatus, wherein the speed reduction apparatus comprises a gear (16), a motor output shaft (15) and a speed reduction case body (6); a driving disc (23) is mounted on an output shaft of the motor and in the speed reduction case body; the upper part of the driving disc is matched with the gear; a clutch base (12) and a clutch fork (11), which are connected, are mounted at the lower part of the driving disc; and a spring (9) is mounted on the output shaft of the motor and between the clutch fork and the inner wall of the speed reduction case body. According to the speed reduction motor, the clutch fork is pulled to make the clutch base drive the ribs on the driving disc to protrude into or retract from openings of the gear so as to control the rotation of the gear, so that the clutch function is realized for controlling the motor to work in a speed-down manner, and the working synchronicity and regulatory precision of the motor are improved. The speed reduction motor is particularly applied to switch control of garage doors.
Description
Technical field
The present invention relates to a kind of reducing motor.
Background technology
Motor is generally made up of motor body assembly and deceleration device, wherein: motor body assembly comprises commutator (i.e. commutator), armature winding, rotor (i.e. armature core), stator (i.e. magnetic shoe), casing, armature shaft etc.; Deceleration device comprises motor output shaft, gear (i.e. worm gear), deceleration box etc.; Described casing and deceleration box cooperation tighten together, and one end of described armature shaft is snail rod shaped structure, the snail rod shaped structure of this armature shaft and gear (both engagements) composition worm-and-wheel gear (namely deceleration transmission is secondary).This motor can be applicable to civilian garage door, and it matches with the control system of garage door, and is connected with the clutch in this control system, carries out whole-process control to the switch of garage door.Because this motor and clutch are installed separately as two parts, sometimes work when coordinating and can not reach Complete Synchronization, operating efficiency, cooperation accuracy all receive certain impact, and the cost dropped into is also higher.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of reducing motor with clutch function, be intended to realize the synchronism of the deceleration of motor and clutch, improve the accuracy controlled.
The object of the invention is to realize by following technical solution: the reducing motor of band clutch function, comprise motor body assembly, deceleration device, described deceleration device comprises gear, motor output shaft, deceleration box, on described motor output shaft and at deceleration box built with drive plate, match with gear in the top of this drive plate, the bottom of this drive plate is equipped with connected clutch base and clutch yoke, on described motor output shaft and between clutch yoke and the inwall of deceleration box, spring is equipped with at place.
After adopting structure of the present invention, by clutch base, the prominent muscle on drive plate is stretched into or exits the opening of gear by stirring clutch yoke, with the rotation of control gear, realize clutch function and control the decelerating operation of motor, improving the synchronism of machine operation and the precision of regulation and control.Be applied to especially on the switch control rule of garage door.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and execution mode, the present invention is described in further detail.
Fig. 1 is the mounting structure schematic diagram of deceleration device of the present invention.
Fig. 2 is the structural representation of the reducing motor of band clutch function of the present invention.
Fig. 3 is the structural representation of drive plate in Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2 is known, the reducing motor of band clutch function of the present invention, comprise motor body assembly, deceleration device, described motor body assembly comprises commutator 19 (commutator), armature winding 20, rotor 2 (armature core), stator 3 (magnetic shoe), casing 1, armature shaft 22, carbon brush 7 (containing electrical carbon spring), described deceleration device comprises gear 16 (and gear cover plate 5), motor output shaft 15, deceleration box 6, on described motor output shaft 15, and at deceleration box 6 built with drive plate 23, match with gear 16 in the top of this drive plate 23, on the bottom of this drive plate 23 (successively) connected clutch base 12 and clutch yoke 11 are housed, on described motor output shaft 15, and spring 9 is equipped with at place between clutch yoke 11 and the inwall of deceleration box 6.Casing 1 and deceleration box 6 cooperation tighten together; Stator 3 is pasted onto in casing 1; The inner outer end of described armature shaft 22 with jackscrew 4, described armature shaft 22 has oiliness bearing 13, in order to the oiliness of the oiliness bearing on armature shaft the inner can be kept for a long time, oiliness bearing 13 on the inner of described armature shaft 22 and between casing 1 place felt circle 14 is housed, and this oiliness bearing 13 is fixed by spring pressuring ring 21; The deceleration transmission of this motor is secondary to be then made up of the snail rod shaped structure on armature shaft 22 and gear 16 (both engagements).
As shown in Figure 1, Figure 3, the top of described drive plate 23 has prominent muscle 24 (several), described gear 16 has opening 8 (several), prominent muscle 24 on this drive plate 23 matches with the opening 8 on gear 16, be conducive to the clutch return of decelerating through motor, be conducive to the de-material after its injection moulding simultaneously when being plastics for gear material and save material.The outer end of described motor output shaft 15 is equipped with spline wheel 17, the other end of described motor output shaft 15 is equipped with three-jaw jump ring 10 with deceleration box 6 touching position, this spline wheel 17 is connected with garage door by power input transfer device again.
As shown in drawings, the operation principle that clutch for clutch control of the present invention is slowed down is: when needs reducing motor job control garage door switch, then stir clutch yoke to be exited from the opening of gear by the prominent muscle of clutch base by drive plate, spring is made to be in compressive state, the armature shaft of motor rotates and driven gear rotates, and then drive motor output shaft rotates, power exports from spline wheel.When motor quits work suddenly, again can stir clutch yoke and by clutch base, the prominent muscle of drive plate be extend in the opening of gear, make spring be in stretched condition, the gear of motor is no longer rotated.Namely by clutch base, the prominent muscle of drive plate is stretched into or exited the opening of gear by stirring clutch yoke, realize the clutch function in reducing motor.
