Abstract: According to a control device for a hydraulic winch, a regulator controls a motor capacity of a hydraulic motor having variable capacity functioning as a driving source of the hydraulic winch in response to a load pressure, a negative brake stops and retains the hydraulic motor at an automatic shutoff for prevention of overloading, and a controller sends signals to the regulator via a regulator-controlling valve at the automatic shutoff to set the motor capacity at a large value. Thus, the delay to recover the motor capacity at the time of returning from the automatic shutoff that is activated during winding-up of a load does not occur, and a control response is increased.

This arrangement represents a simple device for compensating a torque produced by the gyrostatic effect on a movable axle of machine tolls and production machines.

Abstract: An eccentric planetary traction drive transmission which includes at least two planetary rollers, sun roller member, and a carrier member. One of the planetary rollers is flexible and is positioned between and in contact with an outer ring member and the sun roller member. Rotation of either the outer ring member or the sun roller member wedges the flexible planetary roller within a convergent wedge gap which squeezes the flexible planetary roller between the outer ring member and the sun roll member. Friction between the flexible planetary roller, the sun roller member, and the outer ring member transmits rotational motion and torque between the outer ring member and the sun roller member. The other at least one supporting planetary roller is a supporting roller which supports the sun roller member and the carrier member. A plurality of bearings supports the sun roller member within the outer ring member and the at least one supporting planetary roller.
