Description

. (CLUTCH COUPLING

The invention relates to mechanical engineering. The known clutch is a clutch containing a driven and driving gear half coupling and a synchronous node with a flat ribbon spring placed between them. This device is closest to the invention in its technical essence and the effect achieved. This coupling does not have elastic properties. The purpose of the invention is to expand the functional capabilities of the coupling by imparting elastic properties to it. This goal is achieved by the fact that in the clutch, which contains the driven and driving gear half couplings and the synchronizing unit placed between them with a flat tape spring, the leading coupling half is made in the form of a sleeve and a cup located with the possibility of relative rotation and several tape springs placed between the sleeve and the glass and the ends fixed on them, while the synchronizing unit is made in the form of a friction spring-loaded disk relative to the driven coupling half, installed with the possibility axial movement and interaction with the leading coupling half. FIG. 1 shows a coupling with a partial axial section; in fig. 2, section A-A in FIG. 1. The coupling consists of a leading coupling half, made in the form of a sleeve 1 mounted on the shaft-2, and a cup 3 arranged coaxially with the possibility of relative rotation on the bearing Ts. Several tape-flat springs 5, are fixed between the sleeve 1 and the glass 3 on them ends. A gear ring 6 is rigidly fixed on the glass 3. The driven coupling half 7 is made in the form of a gear disk mounted with the possibility of axial movement on the splined shaft 8.

Between the drive and driven half coupling there is a friction disk 9 mounted on the shaft 8 with the possibility of axial movement. And spring-loaded spring 10.

The clutch works as follows.

Coupling is engaged in the axial direction of the coupling half 7 and moving through the spring 10 is transferred to the disk 9, which interconnects with the ring gear 6. Due to the frictional contact of the disk 9 with the crown 6, the driven shaft 8 accelerates and brakes the cup 3 connected with ring gear 6.

The angular velocities of the half couplings are equalized, providing a shock-free coupling of the teeth of the half couplings; During activation of the clutch spring 5, due to the moments of inertia, the coupling halves 7 of the shaft 8 and the cup 3 are twisted. After switching on, the excess of the accumulator accumulated by the springs 5 is transferred to the driven shaft 8, increasing its rotational speed, while the coupling has elastic properties.

The clutch is disengaged. coupling half 7.

The clutch allows the shafts to engage on the fly with a large difference in angular velocity and dampen vibrations and dynamic loads due to uirugi properties, which expands its functionality.
