Abstract
A method for attaching a plastic barrel configured to guide an output shaft of a mechanical device to a housing for the mechanical device is disclosed. The housing includes a chimney delimited by an upper edge and a base, the chimney being arranged to partially surround the output shaft, the plastic barrel having a lateral protuberance. The method involves at least the following steps: inserting a first end of the plastic barrel into the chimney of the housing until the lateral protuberance axially abuts against the upper edge of the chimney, and at least partially deforming the first end of the plastic barrel in order to form an axial counter-abutment.

A method for attaching a plastic barrel configured to guide an output shaft of a mechanical device to a housing of said mechanical device, said housing comprising a chimney delimited by an upper edge and a base, said chimney being arranged to partially surround the output shaft, the plastic barrel comprising a lateral protuberance, the method comprising:
- inserting a first end of the plastic barrel into the chimney of the housing until the lateral protuberance-axially abuts against the upper edge of the chimney;
- and
- at least partially deforming the first end of the plastic barrel in order to form an axial counter-abutment.
An assembly of a housing for a mechanical device comprising:
- a chimney configured to at least partially surround an output shaft of the mechanical device, wherein the chimney comprises a base comprising a substantially conical inner shape flared towards the inside of said housing:
- and
- a plastic barrel comprising a lateral protuberance forming an abutment and delimiting a first end,
- wherein the first end is inserted into the chimney of the housing around the output shaft of the mechanical device, and
- wherein the first end is deformed to form an axial counter abutment.
