ARRANGEMENT FOR ASSEMBLING AN ADJUSTMENT CAP AND A PROTECTOR FOR THE SLIP RING ASSEMBLY OF A ROTARY ELECTRICAL MACHINE

摘要

The invention relates to an arrangement for assembling an annular adjustment cap (40) and a protector (20) which caps a slip ring assembly (10) formed in a rear end section (14) of a rotor (16) of a rotary electrical machine, of the type in which the protector (20) is overall in the form of a cylindrical tube which has an axial opening (34) in a front end section (36) and of the type in which the cap (40) comprises a rear radial partition (60) which has a through hole (61) for the rotor (16) and a rear radial face (59) facing the protector (20) and an annular axial skirt (42) which is intended to house an outer ring (48) of a rolling bearing (50), the bearing (50) being connected such that it rotates as one with the rotor (16). According to the invention, the arrangement comprises means of assembling the front end section (36) of the protector (20) with the radial partition (60) of the cap (20), the assembly means comprising a tubular cylindrical section (36) which can be fitted axially against at least one cylindrical face (63a, 63b) of an additional cylindrical baffle (58).
