Bearing and housing support for intermediate drive shaft
A bearing and housing support including a bearing outer ring overmolded with a thermoplastic bearing housing. The support arranged to support and engage with an intermediate drive shaft of a vehicle.
Turbocharger and method
A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes an outer bearing race element and an inner bearing race element rotatably disposed within the outer bearing race element. The inner bearing race element forms a hollow extension extending up to the compressor wheel, the extension having a hollow cylindrical shape that surrounds a portion of the shaft that is connected on one end to the compressor wheel and at another end is disposed adjacent to a seat formed on the extension portion around the shaft, and a nut engaged on the shaft and disposed within the extension at an offset distance from the seat.
Turbocharger bearing damper assembly
A turbocharger system can include a housing that includes a bore defined at least in part by a bore wall; a rolling element bearing unit that includes an outer race; and a mixed-element damper assembly disposed at least in part between the outer race and the bore wall where the mixed-element damper assembly includes a lobed-spring element and a squeeze film damper element.
Distributed load bearing with an outer flex ring
A distributed load bearing including an outer flex ring, a load distribution spring, and a retainer. The outer flex ring is configured to be positioned radially outwards of a shaft. The load distribution spring is preloaded and positioned radially outwards of the outer flex ring. A radially inner surface of the load distribution spring contacts the outer flex ring. The radially inner surface is an arc defined by a first radius when the load distribution spring is in a lower load distribution mode, and a second radius when the load distribution spring is in a higher load distribution mode. The retainer is positioned radially outwards of the load distribution spring, and the retainer angularly and radially positions the load distribution spring.
Turbomachine bearing support structure
A centering spring assembly of a turbomachine according to an exemplary aspect of the present disclosure includes, among other things, a damper beam, a bearing support, and a spanner nut. At least a portion of the damper beam axially overlaps at least a portion of the spanner nut relative to a rotational axis of the turbomachine.

Turbocharger and method
A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes first and second bearings formed between an outer bearing race element disposed within the bearing bore an inner bearing race element disposed within the outer bearing race element and between the outer bearing race element and the shaft. The inner bearing race element rotates with the shaft and forms an extension segment having an open channel that, together with an annular surface on an inner side of a back of the compressor wheel, forms a U-shaped channel into which a ring seal is disposed. The ring seal sealably engages the inner bearing race element and also slidably and sealably engages the inner bore of the bearing retainer.
Mechanical component, mechanical component manufacturing method, movement, and timepiece
A mechanical component configured to rotate with a shaft member includes a component main body having a through-hole through which the shaft member is passed, and one or more shaft support portions formed on the inner surface of the through-hole to fix the shaft member to the component main body. The one or more shaft support portions protrude from the inner surface of the through-hole and are capable of retaining the shaft member due to an elastic force. The one or more shaft support portions are made of material having a larger elongation percentage than that of the material of the component main body thereby preventing breakage of the mechanical component due to stress created when the shaft member is forced through the through-hole in the component main body.
Distributed Load Bearing with an Outer Flex Ring
A distributed load bearing including an outer flex ring, a load distribution spring, and a retainer. The outer flex ring is configured to be positioned radially outwards of a shaft. The load distribution spring is preloaded and positioned radially outwards of the outer flex ring. A radially inner surface of the load distribution spring contacts the outer flex ring. The radially inner surface is an arc defined by a first radius when the load distribution spring is in a lower load distribution mode, and a second radius when the load distribution spring is in a higher load distribution mode. The retainer is positioned radially outwards of the load distribution spring, and the retainer angularly and radially positions the load distribution spring.
Turbocharger and method
A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes first and second bearings formed within an outer bearing race element having an outer wall that engages a bearing bore along four bearing surfaces that are disposed in pairs around two oil feed galleys formed in the outer wall, the outer wall further forming peripherally extending oil drainage grooves disposed such that oil provided from the oil feed galleys that passes through some of the bearing surfaces drains through the peripherally extending oil drainage grooves.
