Abstract
A transmission includes a shaft-hub connection designed as a serration and having an axial extent along a shaft axis, and an oil supply line to the serration in order to lubricate a relative movement in the serration between a shaft side and a hub side of the shaft-hub connection. The oil supply line is designed to open from radially inward directly into a cavity on the serration to enable supply of oil to the serration at an oil pressure that prevails in the cavity.
Claims16
A transmission, comprising:
- a shaft-hub connection designed as a serration and having an axial extent along a shaft axis;
- and
- an oil supply line to the serration in order to lubricate a relative movement in the serration between a shaft side and a hub side of the shaft-hub connection, said oil supply line designed to open from radially inward directly into a cavity on the serration to enable supply of oil to the serration at an oil pressure that prevails in the cavity, wherein a shaft of the shaft-hub connection at least partially delimits an axially extending supply channel communicating with the oil supply line, and the supply channel is delimited radially inwardly by a pitch tube which corotates with the shaft, and the shaft and the pitch tube form a double-walled pitch tube.
A wind turbine, comprising a transmission, said transmission comprising a shaft-hub connection designed as a serration and having an axial extent along a shaft axis, and an oil supply line to the serration in order to lubricate a relative movement in the serration between a shaft side and a hub side of the shaft-hub connection, said oil supply line designed to open from radially inward directly into a cavity on the serration to enable supply of oil to the serration at an oil pressure that prevails in the cavity, wherein a shaft of the shaft-hub connection at least partially delimits an axially extending supply channel communication with the oil supply line, and the supply channel is delimited radially inwardly by a pitch tube which corotates with the shaft, and the shaft and the pitch tube form a double-walled pitch tube.
