FIELD: machine building.
SUBSTANCE: invention relates to gearings. Sliding screw — nut gearing comprises a screw with an external trapezoidal thread and a female nut with a similar internal thread. On side surfaces of the nut there are pockets connected through throttles to the oil supply channel from the pump. Diametrical surfaces of the nut are made with holes connected to the oil drain channel to the hydraulic tank. Gearing is equipped with an adjustable additional throttle connected to the oil drain channel and a gearbox-multiplier. Hydraulic pump is gear-type reversible, and screw is kinematically connected to its drive shaft through gearbox-multiplier.
EFFECT: reduced wear of gearing.
