Abstract
An adapting part is designed to be held on a casing of a turbo-engine, partially covering the casing. The adapting part includes, in the extension of one of its axial ends, a first connector to engage with a first complementary connector associated with the casing to form a sliding connection. The adapting part also includes, at its other axial end, a second connector to be secured to a second complementary connector associated with the casing to form a rigid connection.
Claims8
An adapting part designed to transmit forces between a tubular casing of a turbo-engine and a suspension of the turbo-engine to a pylon of an aircraft, by partially covering the tubular casing, the adapting part comprising:
- a hoop portion of predetermined angular sector;
- suspension devises arranged on a face of the hoop portion which faces outwards and designed to connect the adapting part to the suspension;
- in an extension of a first axial end of the adapting part, a projecting tab extending axially from the hoop portion and configured to engage with a groove of a connecting member associated with said tubular casing to form an axial sliding connection;
- and
- at a second axial end of the adapting part, a flange configured to be secured to a flange of said tubular casing to form a rigid connection,
- wherein the projecting tab is entirely circular or extends circumferentially over the predetermined angular sector.
A system, comprising:
- an adapting part comprising:
- a hoop portion of predetermined angular sector;
- suspension devises arranged on a face of the hoop portion which faces outwards and designed to connect the adapting part to the suspension;
- in an extension of a first axial end of the adapting part, a projecting tab extending axially from the hoop portion;
- and
- at a second axial end of the adapting part, a flange,
- wherein the projecting tab is entirely circular or extends circumferentially over the predetermined angular sector:
- a tubular casing of a turbo-engine arranged for holding, to the tubular casing, the adapting part;
- a groove of a connecting member associated with said tubular casing which engages with the projecting tab of the adapting part to form an axial sliding connection in a first axial end of the tubular casing;
- and
- a flange of said tubular casing which engages with the flange of the adapting part to form a rigid connection in a second axial end of the tubular casing.
