Abstract
The utility model discloses an electromagnetic clutch, wherein a driving wheel (5) is sleeved on a shaft (1) through a bearing, an iron core (10) which is winded with a coil (8) is sleeved on the shaft (1) through the bearing, a sucker plate (6) between the driving wheel (5) and the iron core (10) is also sleeved on the shaft (1) and moved along the axial direction on the shaft (1), a key (3) is fixed on the shaft (1), the key (3) is positioned on the one lateral of the driving wheel (5) which faces the sucker plate (6), the sucker plate (6) is provided with a key groove (13) which is matched with the key (3), a pin (4) is penetrated through the driving wheel (5) and is fixed on the sucker plate (6), an offsetting spring (2) is arranged between the iron core (10) and the sucker plate (6), the root portion of the offsetting spring (2) is fixed in a spring groove of the iron core (10) which is closed to the shaft (1). The electromagnetic clutch has simple and small structure, low accurate requirement for elements, lower cost, small noise and good stability, which is particularly applied to the occasion of small power drive.
Description
Technical field
The utility model relates to a kind of magnetic clutch.
Background technique
Existing magnetic clutch mainly is high-power clutch.Permanent magnetism is also contained in some electromagnetic clutch mechanism.These electromagnetic clutch complex structures, power consumption is bigger, and component requirement on machining accuracy height is inapplicable to the occasion of small-power transmission.
As disclosed a kind of magnetic clutch among the Chinese patent ZL03105474.9, it utilizes the elastic member that adapts to leaf spring elastic force to reduce the operation noise with lower cost.Though this magnetic clutch is carefully thought out aspect noise, it is complicated that therefore mechanism also becomes, and location and part size requirement are higher, and have hidden danger in the electromagnetic coil heat radiation.
The model utility content
The purpose of this utility model just provides a kind of magnetic clutch, and it is simple in structure, small and exquisite, and the component required precision is low, and is with low cost; Noise is little during use, and good stability is particularly suitable for the occasion of small-power transmission.
The utility model solves its technical problem, the technological scheme that is adopted is: a kind of magnetic clutch, drive wheel is together on the shaft by bearing housing, the iron core that is wound with coil is together on the shaft by bearing housing, adhesive dish between drive wheel and the iron core also is linked in axle and goes up and can move axially on axle, be fixed with key on the axle, this key is positioned at the side of drive wheel towards the adhesive dish; The adhesive dish is provided with the keyway suitable with key; Pin passes drive wheel and is fixed on the adhesive dish; Be provided with Returnning spring between iron core and the adhesive dish.
Working principle of the present utility model and process are: when drive wheel rotated, drive wheel drove the adhesive dish by the pin carry-over moment and rotates.When coil blackout, Returnning spring resets, and pushes the adhesive dish to the drive wheel direction, the keyway of adhesive dish engages mutually with key on the axle, and the adhesive dribbling moving axis of rotation rotates, and this moment, clutch was in the state of " closing ", the transmission of power of drive wheel is given axle, externally output; When coil electricity, electromagnetic core attracts the adhesive dish, the elastic force that the adhesive dish overcomes Returnning spring makes the adhesive dish move to the iron core direction, key on the keyway of adhesive dish and the axle breaks away from, this moment, the rotation of drive wheel can only drive the adhesive commentaries on classics of circling or whirl in the air, together rotate and can not drive axle, clutch be in " from " state, the power of drive wheel can not pass to axially outer output.
Compared with prior art, the beneficial effects of the utility model are: utilize the key and the matching relationship of the keyway on the adhesive dish on the axle dexterously, the purpose of realization intermittently-driving.Key and the occasion that is applicable to the small-power transmission cooperating of keyway, its machining accuracy requires lower, and overall structure is simple, and volume is little, and is in light weight, and processing and fabricating is easy; In addition, the adhesive that the effect by electromagnetic coil and Returnning spring realizes adhesive dish and axle with separate, required power consumption is little.
The root of above-mentioned Returnning spring is fixed in the spring groove of iron core near the axle place.
Below in conjunction with accompanying drawing and concrete mode of execution to further detailed explanation of the utility model.
Description of drawings
Fig. 1 is the utility model embodiment, the keyway of electromagnetic coil energising, adhesive dish with spool on the structural representation of key when not cooperating.
Fig. 2 is the utility model embodiment, the keyway of electromagnetic coil outage, adhesive dish with spool on the structural representation of key when cooperating.
Embodiment
Fig. 1,2 illustrates, a kind of embodiment of the present utility model is: a kind of magnetic clutch, drive wheel 5, the iron core 10 that is wound with coil 8 are combined on the axle 1 by bearing housing, adhesive dish 6 between drive wheel 5 and the iron core 10 also is linked on the axle 1 and can moves axially on axle 1, be fixed with key 3 on the axle 1, the axial position of this key 3 is positioned at the side of drive wheel 5 towards adhesive dish 6; Adhesive dish 6 is provided with the keyway 13 suitable with key 3; Pin 4 passes drive wheel 5 and is fixed on the adhesive dish 6; Be provided with Returnning spring 2 between iron core 10 and the adhesive dish 6.The root of Returnning spring 2 is fixed in the spring groove of iron core 10 near axle 1 place.
Fig. 1 illustrates, under the situation of these routine electromagnetic coil 8 energisings, adhesive dish 6 is produced electromagnetic attraction, make adhesive dish 6 compression reseting springs 2, shift to iron core 10, thereby the key 3 near drive wheel 5 separates on the keyway 13 that makes adhesive dish 6 and the axle 1,5 drives of drive wheel this moment adhesive dish 6 rotates, axle 1 does not rotate, clutch be in " from " state, by axle 1 outputting power.
Fig. 2 illustrates, and this routine electromagnetic coil is under cold situation, and Returnning spring 2 promotes adhesive dish 6 to drive wheel one side shifting, realization resets, the keyway 13 of adhesive this moment dish 6 and the key 3 on the axle 1 agree with, and the adhesive dish 6 that drive wheel 5 drives rotates, and adhesive dish 6 drives axle 1 rotation simultaneously.Clutch is in the state of " closing ", by axle 1 outside outputting power.
Magnetic clutch of the present utility model can be used in intermittent type easily and rotate billboard, page-turning device, turns over spectrum machine etc. and need intermittently transmit on the device of small-power power; And two magnetic clutchs can be installed on same device, to drive the intermittence of realizing single motor, both direction.
