Description

Chaga 23, installed in the winch's corn and tightened to the turns of the cable 24 on the drum.

The driven element 25 of the variator is clamped to the driving element 19 by means of the spring 26. The rollers 15 and 16 are mounted in the carriage 27, movable along the axis of the drum with the driving screw 28.

When winding or winding the cable, rotation from the drum through the gears 5-12, the drive 19 and the driven 25 elements of the speed variator and the mechanism for changing the gear ratio 13 is transmitted to the rollers

15 and 16, rotating faster (when winding up) or slower (when winding) relative to the converging coil of the cable, thereby providing a snap of the cable.

In this case, the gear ratio of the gearbox set is chosen on the basis of advancing (not winding) the rotation of the rollers relative to the cable turn of the uppermost row having a maximum speed, and ensuring that the rollers do not rotate relative to the turn of the cable of the first row having a minimum speed 2-4%.

Change the speed of rotation of the rollers 15 and

16, the carriage at the reverse is automatically provided by the mechanism for changing the gear ratio 13.

When the winch is operating, the spring-loaded lever 23 tracks the cable and gets angular deviations when the coils move from one row to another, i.e. when the cable speed changes due to a change in the piling radius of its turns on the drum.

These angular deviations of the lever 23 are transmitted to the gear 22, which is engaged with the rail 21, which through the pulley 20 converts the rotation of the lever into the translational movement of the leading element 19 of the speed variator, thereby changing its gear ratio according to the cable's regularity.

At the same time, when the cable is transferred from the upper row to the lower leading element of the variator, it moves to the left, the gearbox gearbox gear ratio increases and the speed of the rollers 15 and 16 is reduced by an amount corresponding to a decrease in the cable speed. Also, the gear ratio of the treadslayer gearbox and the transition of the cable from the lower row to the upper, but

In this case, the driving element receives an axial movement to the right and the gear ratio of the gearbox decreases, whereby the carriage rollers increase their speed correspondingly to an increase in the speed of the cable with

transition to the next upper p.

Thanks to the above-described treadsheet construction, a constant optimal speed difference between the carriage rollers and the coil of the converging cable is ensured

from the happyness of the latter.

This greatly increases the durability of the cable and, consequently, the reliability of the winch trough-laying. ,
