Description

FIELD OF THE INVENTION The invention relates to hoisting mechanisms, in particular to crane winches, and can be used in hoisting machines.

The purpose of the invention is to reduce the complexity and ease of installation of the winch.

In FIG. 1 shows a crane winch, general view; in FIG. 2 - the same side view; in FIG. 3 is a section A-A of FIG. 1; in FIG. 4 is a section BB in FIG. 1.

The crane winch comprises a gearbox 1, an electric motor 2, a brake 3 of a cable drum 4. A flange-mounted electric motor is rigidly fixed to the gearbox 1 and connected to its high-speed shaft. A hub 5 is fixedly mounted on the output shaft of the gearbox, bolted to the drum. The gearbox 1 and drum 2, which are a single unit, are mounted on the crane metal structures using three spherical supports. The spherical bearing 6 is mounted in the end face of the drum 2 coaxially with the output shaft of the gearbox 1, and the spherical bearing 7 is mounted in the gearbox housing also coaxially with its output

The supports 6 and 7 are provided with axles 8 and 9,

fixed on the crane metalwork in split supports 10 and 11.

The third spherical support is made in the form of a link 12 with spherical bearings at the ends at the points of connection with the gearbox 1 and the crane metal structure.

To mount the winch on the metalwork, it is necessary to install the axle shafts 8 and 9 of the detachable support 10 and 11 and fix it firmly. Then mount the rod 12, connecting it with the metal structure and the ice gear through spherical bearings 13.

No further adjustments are required.

The winch works as follows.

Torque from flanged electric. the rod 2 through the gear 1 is transmitted to the cable drum 4 through the hub 5 and the bolts.

All the winch loads from the rope are transmitted through the spherical bearings 6 and 7 on the axle shafts 8 and 9 installed in the split supports 10 and 11. on the crane metal structure.

The reactive moment from the winch is transmitted through an articulated bearing 13 on a thrust, and then through a second bearing 13 to the crane metal structure.

Claims (1)

The claims A crane winch containing a rope drum and a gearbox, the output shaft of which is rigidly connected to the hub of the drum, while the drum and gearbox are mounted on the crane metalwork using three spherical supports, one of which, located coaxially with the output shaft of the gearbox, has a drum mounted, and on two other bearings mounted gear with a rigidly mounted electric motor on it, characterized in that, in order to reduce the complexity and ease of installation of the winch, the drum is mounted on the specified spherical bearing its end, the gearbox is mounted on the first spherical bearing with its body, and the second spherical bearing of the gearbox is made in the form of a rod with spherical bearings at the ends, while the spherical bearing of the drum and the first spherical bearing of the gearbox are equipped with axles rigidly fixed to the crane metal structure.
