SU310066A1 - ELASTIC COUPLING - Google Patents

Description

The invention relates to devices for connecting coaxial rotating shafts and is an elastic coupling.

Known elastic couplings contain leading and driven coupling halves, covering one another and made with radial grooves, in which the installed packages of leaf springs.

A feature of the described invention is that the leaf springs are insulated with each other — here and there — by layers of elastic mass.

Such a difference makes it possible to eliminate the lubrication of the spring side surfaces and to reduce the operation noise of the coupling.

In order to realize a smoother transmission of torque, the leaf springs are made of different lengths, forming an inclined groove in the upper part of the package, the plates being longer in the outer parts of the package and shorter in the central part.

In order to eliminate the dead stroke when the clutch is turned on, the spring packages are inserted into the radial grooves of the coupling halves with tension.

The drawing shows the proposed coupling.

tallic plates 5. Between plastids 5 layers 6 of elastic mass are laid.

When rotating, for example, half-coupling I, the working surface of the groove deforms primarily extreme, longer plates 5. As the load increases, deformation is transferred to an increasing number of plates, and due to the special shape of the groove of the articulated coupling half, the place of application of the deforming force shifts to the base of the package plates, which increases their rigidity. The elastic mass layers 6 separating the plates 5 eliminate friction between them.

Subject invention

1. The coupling coupling, containing the driving and driven coupling halves, covering one another and made with radial grooves in which leaf spring packages are installed, characterized in that, in order to eliminate lubrication of the working side surfaces of the springs and reduce the operation noise of the coupling, the leaf springs are insulated one by one with elastic pads.

package of trapezoidal springs called, and the outer sections of the package plate have a greater length, and the central section - a smaller one.

3. Coupling on PP. 1 and 2, characterized in that, in order to eliminate the dead stroke when the coupling is turned on, the spring packages are inserted into the radial grooves of the coupling half with tension.
