  • Patent number: 10498186
    Abstract: A cap for a rotating electric machine, the cap comprising at least a rolling bearing receiving portion (2) for receiving a rolling bearing (R) having an outer race (E), the rolling bearing receiving portion (2) comprising a radially resilient central portion (3) configured to exert pressure on the outer race (E) of the rolling bearing.

  • Publication number: 20180262076
    Abstract: A closure system between the cap and the stator in an electric rotating machine, wherein the stator (1) comprises at least one closure hole (1a) defining an inner wall (1b). The cap (2) comprises at least one contact portion (2a), the end of the contact portion comprising at least one through-hole (2c); the through-hole (2c) being substantially aligned with the closure hole (1a) when the end of the contact portion (2a) contacts the stator (1); and wherein a polymer (P) is injected through the through-hole (2c) in the inner wall (1b) of the closure hole. In the closing process of the present invention, the concentricity between the rolling bearing and the stator rotor accommodating bore is ensured by the fact that the geometry of the rolling bearing receiving portion (2e) allows the alignment to be made on the basis of the outer race (E) of the rolling bearing when it is already accommodated in the receiving portion (2e).
