Method of forming a retaining collar, in particular, a collar retaining a bearing on a hub of a wheel

摘要

A method of forming an annular collar (11) that is essentially radial on the hollow annular end portion (12) of a part (7), said method comprising the following steps:-radially deforming the end portion (12) by means of a first tool (16), the axis (18) of the tool (16) and the axis (5) of the end portion (12) forming a non-zero angle alpha between them, so as to obtain a collar preform (17) that is essentially radial; and-deploying said preform (17) by means of a second tool (23), so as to obtain final shaping of the collar (11) by pressing. The invention also relates to a method of retaining a bearing (1) on a shaft (7), and to an assembly comprising a shaft (7) and a bearing (1).
