SU176760A1 - COMBINED ELECTROMAGNETIC CLUTCH IN NON-CONTACT MANUFACTURE - Google Patents

Description

Cam clutches are known, consisting of two coupling halves, one of which is fixed fixedly on the drive shaft and the other moves on the shaft or on the shaft along the driven shaft; both coupling halves are provided with end cams entering the hollows of the other coupling half. Limes are also electromagnetic non-contact electromagnetic couplings, including magnetic core with winding, intermediate dns and measles. The proposed combined electromagnetic clutch in a contactless isnolienni differs from the known ones in that it consists of one driving half coupling and two slave coupling (cam and electromagnetic) coupling half; moreover, only one of them can be involved in work by means of a gearing connecting the coupling with the drive and one of the driven shafts, which are parallel to each other outside the coupling housing. The intermediate disk by the electro-coupling of the coupling coupling, the cam coupling coupling and the coupling coupling drive coupling coupling are provided with toothed gear crowns for connecting the drive and driven shafts with the respective coupling sleeves. Such an embodiment of the clutch creates the possibility of transmitting torque to one nz of two driven shafts parallel to the drive shaft, and provides a light and simple gearshift transmission of the drive shaft rotation to one or the other driven shaft. FIG. 1 shows a diagram of the proposed coupling; on fng. 2 is a diagram of the transmission of rotational motion from the drive shaft) ia driven shafts; on fng. 3 - knnematic scheme of rotational transmission with a definite torque. The combined electromagnetic coupling contains the housing /, the magnetic conductor 2, mounted on the housing, and the shaft 3. On the latter there is a drive coupling half consisting of a core 4 with a gear ring 5 and a cam coupling half 6, and an intermediate disk 7 with a gear teeth 8 electromagnetic coupling half and cam coupling zero coupling 9 with ring gear 10. When the de-energized winding of the cam coupling, consisting of cam jaw couplings 6 and 5, is always in the price tag of the recoil spring /./. During this, between corona 4 and the intermediate disk 7 The thrust gap S required for the disconnected frictional surfaces of the core 4 and the intermediate disk 7. In this description, the described coupling transfers the torque ring from the drive shaft 12 to the driven shaft 13 through the cam clutch (Fig. 2).

The intermediate disk 7, fixed on the shaft 5, rotates freely relative to the housing /, the magnet 2, the master and the driven cam-zero couplings.

The anchor 4, the intermediate disc 7 and the cam of the half-coupling 9 are provided with gear teeth 5, 8 and 10, respectively, for connecting the drive and driven shafts with the respective coupling halves.

When power is applied to the winding of the combined electromagnetic coupling, the magnetic flux, closed through the magnetic conductor 2, the intermediate disk 7 and the measles 4, creates a force that attracts the measles 4 to the plane of the intermediate disk 7 and ensures their friction coupling. In this position, disengagement occurs - the cam clutch disengages.

Due to the friction clutch of the core 4 with the intermediate disk 7, the torque is transmitted from the drive shaft 12 connected to the ring gear 5 core to the driven shaft M connected to the ring gear 8 of the intermediate disk.

When removing the voltage from the winding of the described coupling, the friction surfaces of the core 4 and the intermediate disk 7 are uncoupled. The cam coupling half 6 engages with the driven cam coupling half 9. In this position, through the cam coupling, the gear is transmitted torque from the drive shaft 12 to the driven shaft 13.

When used in devices and mechanisms, a combined electromagnetic clutch can transmit rotational motion with a specific torque according to the following kinematic schemes:

from one kinematic chain 15 to one receiver of displacements 16 (Fig. 3 a);

from two kinematic chains 15 to one displacement receiver 16 (FIG. 3 b);

from one kinematic chain 15 alternately to two receivers of displacements 16 (Fig. Sv);

from one kinematic chain 15 to the receiver displacement 16 through the cam clutch (Fig. 3 g);

from one kinematic chain 15 to the receiver displacement 16 via electromagnetic

clutch. In this case, the cam clutch is used for braking the actuator of the receiver of displacements when the clutch winding is de-energized (Fig. 3e).

The operation of the combined electromagnetic coupling according to all kinematic schemes is carried out by the flow of the cable and the coupling of the coupling winding.

Combined electromagnetic clutch

It does not have a neutral position of the drive half coupling, because the coupling half is either always in cam engagement with the driven coupling half when the coil is de-energized, or in the friction connection with the intermediate disc 7 when the winding is on.
