Abstract

The utility model relates to an electromagnetic clutch and transmission means which is suitable for a plurality of occasions where electromagnetic control is needed to achieve the intermittent drive relations. The utility model is also provided with a drive pulley and a transmission sleeve fixedly connected with the drive pulley, a driven shaft and electromagnetic coils and support frame casings thereof, wherein, both the drive pulley and the transmission sleeve are sheathed on the driven shaft. The utility model is characterized in that a pair of electromagnetic coils and the support frame casings thereof are free sheathed on the driven shaft, one of the electromagnetic coils and the support frame casing thereof are free sheathed on the driven shaft through the transmission sleeve, the electromagnetic coil and the transmission sleeve opposite to the support frame thereof are not in transmission connection with each other, and the two electromagnetic coils and the support frame casings thereof are spaced through a ferrule in between and left with interspace oppositely; a driving disc is sheathed on the driven shaft in the interspace, and both end surfaces of the driving disc are opposite to both end surfaces of the two electromagnetic coils, wherein, one end surface is directly corresponding to the end surface of the transmission shaft, and the driving disc is connected with the driven shaft in endwise slip fit and rotation linking matching mode.

Description

Electromagnetic clutch gearing

The utility model is applicable to the multiple occasion that needs Electromagnetic Control to realize the intermittently-driving relation about a kind of electromagnetic clutch gearing.

What the electromagnetic clutch gearing mode of structure was known has several, and with the invention more approaching also be that more novel a kind of correlation technique is disclosed on the Chinese utility model patent text CN2254970Y, these electromagnetic clutch gearing characteristics are to have changed to use elastic claw rotary driving mode in the past but employing torque spring and described brake disc, braking sleeve and driving wheel, be engaged between the driven wheel electromagnet (should be meant electromagnetic coil) electric and dead electricity alternately in, driven axle carries out the clutch transmission under torsion spring metamorphosis power is ordered about, but still there is fatal shortcoming in the electromagnetic clutch gearing of this structure, be that torsion spring distortion and wearing and tearing and transmission retardation phenomenon are inevitable, use not long with the life-span.

The purpose of the utility model is will overcome the deficiency that above-mentioned prior art exists and provide that a kind of clutch transmission is reliable rapidly, the electromagnetic clutch of compact structure passes device.

The drive sleeve that this electromagnetic clutch gearing still has driving wheel and is fixedly connected, driven axle, electromagnetic coil and support shell thereof, the equal sky of driving wheel and drive sleeve is enclosed within on the driven axle, it is characterized in that having a pair of electromagnetic coil and support shell sky thereof to be enclosed within on the driven axle, wherein an electromagnetic coil and support shell thereof are enclosed within on the driven axle by the drive sleeve sky, and the relative drive sleeve of this electromagnetic coil and support thereof is not in transmission connection yet, between two electromagnetic coils and the support shell thereof by the spacing space of leaving relatively of lasso, in this space, be with drive plate on the driven axle, the relative two electromagnetic coil end faces of drive plate both ends of the surface, wherein, one end face is directly corresponding with the transmission shaft end face, and drive plate is connected with driven axle and is axial sliding fit and rotates the mode of being linked.

Its working principle of the utility model of tool said structure characteristics is as follows, when drive plate gets electric respectively adhesive at the two relative electromagnetic coils that replace, wherein an electromagnetic coil is enclosed within on the drive sleeve that is fixedly connected with driving wheel, drive plate links with the adhesive of drive sleeve end face during by this electromagnetic coil adhesive, driven axle promptly also is driven, when otherwise drive plate is got electric adhesive by another electromagnetic coil, because this electromagnetic coil and support shell thereof and driven axle are not in transmission connection, drive plate separates with drive sleeve again, driven axle is not driven, the clutch of this clutch drive mechanism is reliable rapidly, and the member annexation is simple, and structure all is arranged on the driven axle axis, compact overall structure, in addition, do not have a structural member distortion stressed, make whole device have more reliable and practical property.

Further illustrate the utility model below in conjunction with description of drawings and provide embodiment simultaneously.

Fig. 1 is the utility model embodiment partial view.

Wherein, 1, brush spring, 2, driven axle, 3, driving wheel, 4, drive sleeve, 5, the coil external connection, 6, electromagnetic coil support shell, 7, electromagnetic coil, 8, (spacing) lasso, 9, drive plate, 10, rolling bearing, 11, electromagnetic coil, 12, pin, 13, lettering wheel carrier, 14, type wheel, 15, connect stopper rod.

As shown in the figure, this is that the utility model is applied in one of electromagnetic clutch transmission example on the seaming machine type wheel, matching parts beyond the utility model theme is simplified the omission explanation relatively, for example, being provided with electric heating tube in driven axle (2) cavity of employing center cavity also repeats no more also omitting in the structural drawing such as type wheel 14 heating.Driving wheel 3 in the present embodiment is connected with drive sleeve 4 fixed conveyor, also they can be set as one, electromagnetic coil 7 and support shell 6 thereof are enclosed within on the drive sleeve 4 and by rolling bearing 10 and drive sleeve 4 and constitute the relation that is not in transmission connection, drive sleeve 6 and active arbor wheel 3 skies thereof are enclosed within on the driven axle 2, another electromagnetic coil 11 and support shell 6 direct skies thereof are enclosed within on the driven axle 2, present embodiment is provided with rolling bearing 10 and comes this empty cover of note to be connected relation between electromagnetic coil support shell 6 and driven axle 2, this structure arrangement has guaranteed electromagnetic coil 7,11 and support shell 6 not with driving wheel 3 by any way transmission make it to rotate, two electromagnetic coils 7, be enclosed within the clearance distance that limits on the support shell 6 between the two by (spacing) lasso 8 between 11, in this clearance distance, be with drive plate 9 on the driven axle 2, being provided with pin 11 between this drive plate 9 and the driven axle 2 cooperates with drive plate 9 axial elongated slots and sets the axial sliding fit between drive plate 9 and the driven axle 2 and rotate the annexation that interlock cooperates, at this moment, drive plate 9 both ends of the surface are respectively in the face of an electromagnetic coil 7,11 end faces, wherein an end face is directly faced the end face of drive sleeve 4, in the present embodiment, the end face of this drive sleeve 4 is the ring plate-like, and relative electromagnetic coil 7 is close neighbour's drive plate 9 more, help drive sleeve 4 and drive plate 9 adhesive linkage reliabilities, drive plate 9 is at two electromagnetic coils 7, axially has certain mobile space in the relative clearance distance between 11.
