Description

The invention relates to machine-building; Oio can be used in drives and machines for transmitting torque in the presence of misalignment of the connected shafts.

Gear couplings are known that contain leading and driven coupling sleeves and a gear element between them, made in the form of two gear sectors with shanks intertwined in engagement, loose on the fingers fixed to the flange of the driving half coupling and fitted with spherical rollers that interact with grooves, and watched in the driven half of the clutch.

The proposed gear coupling differs from those known in that the gear element is made in the form of a nlesterni fixed on the drive half coupling, on which a swinging lever with a hole is freely mounted, and a kinematically gear connected with it mounted in the said hole of the lever and having an eccentric bore for secured in the half drive coupling pin with the support.

This embodiment of the coupling increases its reliability and simplifies the constitution.

FIG. 1 shows the described coupling in section; in fig. 2 shows a section along L-ka of FIG. one.

The described coupling consists of a driving loader / with a fixed gear 2, kinematically connected with a gear wheel 3, mounted with its shank in a bore of a swinging lever 4, mounted on a gear hub. At the end of the flange of the driven coupling half 5, the pin 6 is rigidly fixed, bearing a rolling bearing 7. The latter enters an eccentric bore provided at the end of the gear.

The torque is transmitted from the driving half coupling / gear 2, centered to the gear 3, and then perceived by the driven coupling half 5 through the pin 6 with a bearing of quality 7.

The compensation of the radial shift of the axes of the connected shafts is achieved by the relative rotation of the gear wheel 3 and the swing of the lever 4 around gear 2.

To compensate for the angular displacement of the axes of the shafts, the bearing is adopted of a radial two-row spherical type, which ensures the self-alignment of the outer ring when the finger axis is tilted relative to the axis of the eccentric bore in the gear wheel 5.

Subject invention

A toothed clutch containing a driving and driven half coupling and a toothed element between them, characterized in that, with uCvTbio, increasing the reliability of operation with misalignment of the shaft connection, the toothed element is designed as a pinion fixed on the leading coupling half, on which a freely waving lever with a hole, of a kinematically gear mounted therewith mounted in said lever hole and having an eccentric boring for a pin with a bearing fixed in the driven coupling half,
