Abstract
A coupling device (10) for a gear wheel (12), a pulley or other similar units comprising a support (18) for a gear wheel (16) or an operating portion of the pulley or unit, means for centering and drawing the crown gear (16) or the operating portion on the support and means for holding the crown gear (16) or operating portion against the support (18) along a parallel direction relative to a rotation axis of the gear wheel or pulley or unit, said means comprising a locking member (34) suitable to be fixed to the support (18) for defining an abutment for the crown gear (16) or operating portion.

A coupling device (10) of a gear wheel (12), a pulley o other similar units comprising a support (18) for a gear wheel (16) or an operating portion of the pulley or unit, means for centering and drawing the crown gear (16) or the operating portion on the support and means for holding the crown gear (16) or the operating portion against the support (18) along a direction parallel to a rotation axis of the gear wheel or pulley or unit, said means comprising a locking member (34) suitable to be fixed to the support (18) for defining an abutment for the crown gear (16) or the operating portion.
The coupling device according to claim 12, wherein the at least one tooth (36) is formed at a spoke (30) connecting a central portion (20) to a peripheral portion (32) of the support (18).
The coupling device according to at least one of preceding claims, wherein the support (18) is suitable to be splined or coupled to a shaft (14).
The coupling device according to one of preceding claims, wherein the means for centering and drawing the crown gear (16) comprise projections of the support (18) that are suitable to be fitted within seats of the crown gear, or pins or threaded dowels (24) suitable to be axially fitted within relative seats (26 and 28) of the crown gear (16) and support (18), respectively.
A method (10) for coupling a gear wheel (12), a pulley or other similar units comprising a support (18) for a crown gear (16) or an operating portion of the pulley or unit, said coupling method comprising the steps of:
- centering the crown gear (16) or the operating portion on the support (18);
- associating a locking member (34) to the support (18) such that this locking member (34) defines a constraint in the axial direction between the crown gear (16) and the support,
- fixing the locking member (34) to the support (18) for defining an abutment for the crown gear (16) or the operating portion.
