Abstract: A device for uncoupling a bearing carrier in a turbomachine, the bearing carrier including an upstream part and a downstream part including a plurality of upstream orifices respectively facing a plurality of downstream orifices. The uncoupling device includes rupture screws each passing through an upstream orifice and a downstream orifice, and at least a mechanism for double centering of a rupture screw with respect to the upstream orifice and to the downstream orifice respectively. The mechanism for double centering is independent of the upstream and downstream parts of the bearing carrier and of the rupture screw, and is configured to collaborate with the upstream part of the rupture screw such that when the rupture screw breaks, the upstream part carries with it the mechanism for double centering. A turbomachine can include such an uncoupling device.

Abstract: The invention relates to a device for decoupling a bearing bracket in a turbomachine, said bearing bracket having an upstream part and a downstream part respectively comprising a plurality of upstream holes and downstream holes through which stress-limiting screws pass, which device comprises, between each upstream hole and the stress-limiting screw that passes through it, a clearance that prevents any contact between the upstream hole and the stress-limiting screw, and is a device wherein the upstream part and the downstream part of the bearing bracket are in mutual contact via surfaces that form a dual centering means.
