The utility model discloses a hydraulic friction clutch for an anchor gear and a winch reduction gearbox. The hydraulic friction clutch comprises a main shaft, a movable cylinder, a first friction plate group, a second friction plate group, a first gear and a second gear, wherein the main shaft is internally provided with a first oil cavity and a second oil cavity; an annular bulge end is arranged on the external circumference of the main shaft; the movable cylinder comprises a first moving block, a second moving block and a telescopic spring; the first moving block comprises a first oil pressing end and a first external fixing end; the second moving block comprises a second oil pressing end and a second external fixing end; the first oil pressing end and the second oil pressing end are separated by the annular bulge end of the main shaft; the first oil pressing end and the second oil pressing end are internally provided with an oil pressing cavity; the telescopic spring is arranged in the oil pressing cavity; the first external fixing end and the second external fixing end are fixed together; each of the first friction plate group and the second friction plate group comprises kinetic friction pieces and static friction pieces at intervals. The hydraulic friction clutch can solve the technical problems about dynamic meshing of gears, stable meshing and small impact.
