Abstract
In order to facilitate the disassembly of a transmission shaft in a turbomachine, an arm for turbomachine casing comprises a body provided with a recess housing a removable part which delimits a shaft housing and is capable of being inserted through a first opening of the recess by means of sliding movement of the removable part parallel to the direction of a central axis of the shaft housing, the first opening of the recess being configured for being arranged opposite an orifice within a casing outer shell ring of the turbomachine.
Claims10
An arm for a turbomachine casing, the arm extending along a longitudinal direction and having:
- a first longitudinal end provided with first attachment means configured for being attached to a casing outer shell ring,
- a second longitudinal end provided with second attachment means configured for being attached to a casing hub,
- two aerodynamic outer surfaces connected to one another at a leading edge of the arm,
- the arm comprising:
- a shaft housing having a central axis which extends in the longitudinal direction of the arm and which is configured to house at least partially a secondary turbomachine transmission shaft, and
- a body forming a first part of each of the two aerodynamic outer surfaces, and comprising at least a part of the first attachment means, and at least a part of the second attachment means,
- the arm being characterised in that:
- the body comprises a recess arranged between a first part of the body situated on a leading edge side and a second part of the body situated on an opposite side, the recess leading to each of the two aerodynamic outer surfaces,
- the recess has a first opening and a second opening which open respectively at the first longitudinal end of the arm and at the second longitudinal end of the arm,
- the arm comprises a removable part housed in the recess so as to form a second part of each of the two aerodynamic outer surfaces,
- the removable part is configured so as to be able to be inserted in the recess through the first opening by sliding movement of the removable part parallel to the direction of the central axis, and
- the removable part delimits at least a part of the shaft housing extending from the first longitudinal end of the arm up to the second longitudinal end of the arm.
