Abstract
The invention discloses an anti-abrasive reducing motor with a clutch function. The anti-abrasive reducing motor comprises a motor body assembly and a speed reducer, wherein a driving disk (23) is arranged on a motor output shaft of the speed reducer and in a reduction box body; the upper part of the driving disk is matched with a gear; a clutch base (12) and a clutch shifting fork (11), which are connected with each other, are arranged at the lower part of the driving disk; and a felt ring (14) is arranged between an oil bearing (13) at the inner end of an armature shaft (22) of the motor body assembly and a machine case (1). According to the anti-abrasive reducing motor, by stirring the clutch shifting fork, a convex rib on the driving disk extends into an opening of the gear or retreats from the opening of the gear by the clutch base, so that rotation of the gear is controlled; the clutch function is realized; the working synchronicity and the regulating accuracy of the motor are improved; the oiliness of the oil bearing can be kept by the felt ring for a long period of time; and the wear-resisting property of the armature shaft is enhanced. The anti-abrasive reducing motor is especially applied to opening and closing control of a garage door.
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.And the armature shaft of motor is easily worn in the process of running up, affect its useful life.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of wear-resistant formula reducing motor with clutch function, be intended to realize the synchronism of the deceleration of motor and clutch, improve the accuracy, the abrasion resistance properties that control.
The object of the invention is achieved through the following technical solutions: the wear-resistant formula reducing motor of band clutch function, comprise motor body assembly, deceleration device, described motor body assembly comprises commutator, armature winding, rotor, stator, casing, armature shaft, carbon brush, 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, connected clutch base and clutch yoke the bottom of this drive plate be equipped with, on described motor output shaft, and spring is equipped with at place between clutch yoke and the inwall of deceleration box, the inner outer end of described armature shaft with jackscrew, described armature shaft has oiliness bearing, the oiliness bearing on the inner of described armature shaft and between casing place felt circle is housed, and this oiliness bearing and felt circle are fixed by spring pressuring ring.
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; Felt circle can keep the oiliness of oiliness bearing for a long time, enhances the anti-wear performance of armature shaft, and then extends the useful life of motor.The present invention is applied on the switch control rule of garage door especially.
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 wear-resistant formula 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 wear-resistant formula 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, the inner outer end of described armature shaft 22 with jackscrew 4, described armature shaft 22 has oiliness bearing 13, 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 and felt circle 14 are by spring pressuring ring 21 fixing (in order to keep the oiliness of the oiliness bearing on armature shaft the inner for a long time).
Wherein, casing 1 and deceleration box 6 cooperation tighten together; Stator 3 is pasted onto in casing 1; 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.
