Description

Single-shaft double-drum friction winches for scraper and shunting work are known. They contain a forcibly rotated longitudinally movable shaft, equipped with threaded shanks with nuts screwed on them that do not have axial movement, when braking the shaft interlacing shaft with the inclusion of a corresponding frictional clutch. Remote control of such a winch is difficult.

In the winch being described, from the control of the control of it, it was used one, permanently closed by the brake, and the electric motor was made reversible.

In drawing P 3, image 1a is a general scheme of a winch.

From the electric motor / through a reducer 2 c about the daily shaft 3 with gear 4, freely, ia to the shaft 5 rotates the gear wheel 6, which is provided with conical pads 7 at both ends. On the same shaft 5 it is also free on both sides of the wheel about the t drums 8 and I with recesses

its brake pulleys OTK 1-L IMPACT with the POD 7. 3

the ends of the shaft 5, weed out in the form of a cut shank and it is covered by a nut 10 devoid of axial movement, covered constantly by the 3aN KHymy brake //.

When the electric motor is reversed, the h / shaft 5 moves to the axillary axis and turns on the corresponding drum. the electrode and the torch is remotely operated.

Subject invention

A winch for scraper and shunting work, made of a single-shaft double-drum friction clutch and hinged on a forcibly rotating shaft with a mounted mn in the middle of 1e with its gear wheel, fitted with end friction elements and a threaded shaft, covered with a nut, for axial movement of the shaft, an axle friction element, and a nut for the axial movement of the shaft, for the axial movement of an axle friction element and a threaded shaft covered by a gear for axial movement
