Abstract
The invention discloses a clutch reduction gear for a motor. The clutch reduction gear comprises a gear (16), a motor output shaft (15) and a reduction gearbox body (6), wherein a driving disc (23) is mounted on the motor output shaft and in the reduction gearbox body; the upper part of the driving disc is matched with the gear; a clutch base (12) and a clutch yoke (11) which are mutually connected are mounted at the lower part of the driving disc; and a spring (9) is mounted on the motor output shaft and between the clutch yoke and the inner wall of the reduction gearbox body. According to the clutch reduction gear for the motor, through stirring the clutch yoke, the clutch base enables ribs on the driving disc to extend into or get out of openings of the gear to control the gear to rotate, so that the engaging and disengaging function is realized to control deceleration of the motor, and accordingly, the operation synchronicity and the regulation and control accuracy of the motor are improved. The clutch reduction gear is particularly applied to opening-closing control of garage doors.
Description
Technical field
The present invention relates to a kind of motor, be specifically related to a kind of speed reducer of motor.
Background technique
Motor is generally made up of motor body assembly (comprising armature shaft) and speed reducer (comprising deceleration box), 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.; Speed reducer 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 gearing down 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, working efficiency, cooperation validity 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 clutch speed reducer of motor, be intended to realize the synchronism of the deceleration of motor and clutch, improve the validity controlled.
The object of the invention is to realize by following technical solution: the clutch speed reducer of motor, comprise 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 mode of execution, the present invention is described in further detail.
Fig. 1 is the mounting structure schematic diagram of the clutch speed reducer of motor of the present invention.
The reducing motor structural representation of the band clutch function that Fig. 2 applies for the present invention.
Fig. 3 is the structural representation of drive plate in Fig. 1.
Embodiment
Known with reference to Fig. 1, the clutch speed reducer of motor of the present invention, comprise 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 between clutch yoke 11 and the inwall of deceleration box 6, spring 9 is equipped with at place.
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 unit again.
As shown in Figure 2, the reducing motor of the band clutch function that the clutch speed reducer of motor of the present invention is applied, also comprise motor body assembly, described motor body assembly comprises commutator 19 (i.e. commutator), armature winding 20, rotor 2 (i.e. armature core), stator 3 (i.e. magnetic shoe), casing 1, armature shaft 22, carbon brush 7 (containing electrical carbon spring) etc.Casing 1 and deceleration box 6 cooperation tighten together; Stator 3 is fastening to be pasted onto in casing 1; The inner outer end of described armature shaft 22 with jackscrew 4, described armature shaft 22 has oil-impregnated bearing 13, in order to the oiliness of the oil-impregnated bearing on armature shaft the inner can be kept for a long time, oil-impregnated bearing 13 on the inner of described armature shaft 22 and between casing 1 place felt circle 14 is housed, and this oil-impregnated bearing 13 is fixed by spring pressuring ring 21; The gearing down 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).
The working 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.
