Abstract
A planet stage of an epicyclic gearing includes a gearing housing with a ring gear arranged in a fixed position, at least two planet wheels mounted in a planet web that has at least one cheek, and a sun wheel. The planet web is connected to an input shaft, and there is a connection between the input shaft and a component of a further planet stage. The planet stage of the epicyclic gearing, in particular the planet web, has a reduced torsional loading. The reduced torsional loading is achieved in that the connection is a connecting web which is connected to that cheek of the planet web which is acted upon by an admission of load/moment, and is arranged in the region between two planet wheels and within the ring gear.
Claims16
A planetary stage of a planetary gear mechanism, comprising:
- a gear mechanism housing;
- an internal gear;
- a planet spider fixedly connected to an input shaft and including at least one cheek;
- at least two planetary gears mounted on the planet spider;
- a sun gear;
- and
- a connecting web arranged within the internal gear in a circumferential region defined between two adjacent planetary gears of the at least two planetary gears, the connecting web connecting the cheek to a component of a further planetary stage so as to rotationally couple the input shaft and the component of the further planetary stage,
- wherein the at least one cheek is loaded by an introduction of load/torque.
A wind power plant, comprising:
- an input shaft;
- a planetary gear mechanism including a planetary stage and a further planetary stage, the planetary stage including:
- a gear mechanism housing;
- an internal gear;
- a planet spider fixedly connected to the input shaft and including at least one cheek;
- at least two planetary gears mounted on the planet spider;
- a sun gear;
- and
- a connecting web arranged within the internal gear in a circumferential region between two adjacent planetary gears of the at least two planetary gears, the connecting web connecting the cheek to a component of the further planetary stage so as to rotationally couple the input shaft and the component of the further planetary stage,
- wherein the cheek is loaded by an introduction of load/torque.
