Description

(54) ELASTIC-CENTRIFUGAL COUPLING

one

The invention relates to mechanical engineering and can be used in precision machines and devices, in which the transmitted torque is small in magnitude, to which increased demands are made on the uniformity of rotational motion and in which relatively large misalignments of the connected shafts are possible.

A centrifugal clutch is known, comprising a leading coupling half with two diametrically spaced figured shanks, a driven coupling half and elastic elements connecting the coupling half. Driven coupling half covers the drive and carries the fingers, which are fixed elastic elements, made in the form of a helical coil spring 1.

This coupling is designed to compensate for large torsional vibrations and transverse variable shock loads.

However, this clutch will not be able to perform its functions with increased misalignment, because of the rigid fixation in the world. home coupling half, helical coil spring, one of the leading shanks

half coupling will take the load to a greater extent than the other.

The purpose of the invention is to increase the compensating capacity of the coupling with the misalignment of the connected shafts.

The goal is achieved by the fact that the elastic elements are made in the form of two half-rings, the ends of which are provided with centrifugal weights and are interconnected by elastic plates interacting with the figured shanks of the drive coupling half, and the coupling coupling half is made with two diametrically arranged tails attached to the half rings located in the same plane perpendicular to the axis of rotation of the coupling.

FIG. 1 shows an elastic centrifugal clutch, general view; in fig. 2 is the same in FIG. 1, cross section.

The driving half coupling is made in the form of a hub 1 with diametrically located figured shanks 2 and 3, ending with semi-cylinders. The driven half coupling consists of a hub 4 with diametrically located shanks 5 and 6. Shanks 5 and 6 are provided with slots for accommodating elastic half-rings 7 and 8 ,. the ends of which are interconnected by means of elastic plates 9 and 10 and fasteners 11 and 12, which play the role of centrifugal weights. The clutch works as follows. In the static position, the figured shanks 2 and 3 of the leading half-coupling are in any position between the tensioned elastic plates 9 and 10 of the elastic element. When the leading half-coupling rotates without load, in the direction indicated by the arrow in FIG. 1, the shaped shanks of this coupling half are pressed against the elastic plates 9 and 10, forming an angle d between the common axes of the shanks 2 and 3 of the driver and 5 and 6 of the driven coupling half. Under the action of torque and at a certain frequency of rotation, the figured shanks 2 and 3 of the leading coupling half try to deform more. Elastic plates 9 and 10, reducing the angle o and compressing the half ring 7 and 8. The increase in the rotation frequency is accompanied by an increase in the centrifugal forces of the fasteners 11 and 12, acting as centrifugal weights and thereby "unclenches the elastic rings of half rings 7 and 8, straightening elastic plates 9 and 10, and thereby increasing the angle of. Thus, at steady state (a certain torsional load and rotation frequency) of the coupling operation, between the torsional load, the deformation forces of the elastic half rings 7 and 8, the plates 9 and 10, and the centrifugal forces of the centrifugal weights are determined by the deformation angle of the coupling. S Coupling coupling half elastic element made of two separate elastic half-rings, the ends of which are interconnected by means of elastic plates and fasteners acting as centrifugal weights, significantly improves the coupling and damping properties of the coupling with increased misalignment of the shafts to be joined, as figured shanks the leading coupling half, located between the elastic plates 9 and 10, can freely move along these plates. Formula of the invention: Elastic-centrifugal coupling containing the leading coupling half With two diametrically shaped figured shanks, a driven coupling half and elastic elements connecting the coupling half, characterized in that, in order to increase the compensating capacities when the shafts are misaligned, the elastic elements are made in the form of two half-rings, the ends of which are equipped with centrifugal weights and interconnected elastic plates that interact with the figured shanks of the leading coupling half, and the half-coupling is made with two diametrically arranged shanks to which the floor is attached ukolts, located in the same plane, perpendicular to the axis of rotation of the coupling, Sources of information taken into account during the examination 1.
