20140205374 | Torque Limiting Tolerance Ring - A torque limiting tolerance ring is disclosed and can include a generally cylindrical body having a sidewall. The sidewall can include an unformed section. A plurality of projections can extend from the unformed section of the sidewall and the plurality of projections can be arranged in a first circumferential row and a second circumferential row. The torque limiting tolerance ring can include a frangible portion that can extend circumferentially around the tolerance ring between the first and second rows of projections. | 07-24-2014 |
20140185164 | Tolerance Ring With Discrete Tolerance Ring Panels - A tolerance ring for a hard disc drive assembly is disclosed and can include a plurality of discrete tolerance ring panels. Each tolerance ring panel can include an arcuate sidewall that can include an unformed portion and at least one projection extending from the arcuate sidewall. The projection can be surrounded by the unformed portion of the arcuate sidewall and the tolerance ring can be configured to be deployed in an interference fit between an inner component and an outer component to provide torque coupling between an inner component and an outer component. | 07-03-2014 |
20140166423 | Torque Limiting Tolerance Ring - A torque limiting tolerance ring that is configured to be installed between an inner component and an outer component is disclosed. The torque limiting tolerance ring can include a generally cylindrical body that can have a sidewall. The sidewall can include an unformed section and a plurality of projections can extend from the unformed section of the sidewall. The projections can be configured to engage the inner component or the outer component. During use, the torque limiting tolerance ring can move from an engaged configuration, in which the inner component is statically coupled to the outer component, to a disengaged configuration, in which the inner component is disengaged from the outer component. | 06-19-2014 |

20110271512 | Assembly of a Shaft and a Housing Assembly - A shaft is held in place within the bore of a housing by means of a band of resilient material that is located between the shaft and the housing and has a series of projections extending radially inwards. The shaft surface has a first part that lies closer to the longitudinal axis of the bore than a second part, when the shaft and housing are assembled. The shaft is initially inserted into the resilient band, which is held within the bore, such that the first part of the shaft surface is oriented towards one of the projections of the resilient band. In this orientation of the shaft, the projection is not compressed. By orienting the second part of the shaft surface the projection, the projection is brought under compression and the shaft is held firmly within the bore. | 11-10-2011 |
20110097144 | COMBINATION MOUNTING RING - A combination mounting ring of resilient material, for connecting a shaft within a bore of a housing, has a hollow cylindrical part having radially extending projections. This part is for locating between the outer surface of the shaft and the inner surface of the bore, the radially extending projections being under compression and thus securing the shaft within the bore. The combination mounting ring further has an axial spring element extending radially inward from the cylindrical part and having two portions at different axial positions. The axial spring element is for locating between the shaft and a body axially displaced from the shaft, and serves to minimize axial movement of the shaft within the bore of the housing. The axial spring element may either be an annular part or a tab extending from an axial edge of the cylindrical part. | 04-28-2011 |
20110076096 | SYSTEM, METHOD AND APPARATUS FOR TOLERANCE RING CONTROL OF SLIP INTERFACE SLIDING FORCES - A tolerance ring comprising a metallic band for spring features and a complementary low friction material for frictional considerations is disclosed. The tolerance ring is designed to operate within a precisely controlled torque or axial force band to provide a defined amount of resistance and sliding force control between components that move relative to each other. Isolated portions of the tolerance ring form regions of contact with adjacent ones of the components. Other surfaces of the tolerance ring comprise portions with spring features that have geometry suitable for their spring rate, rather than conforming to mating surfaces of the adjacent components. | 03-31-2011 |
20100321833 | TOLERANCE RING ASSEMBLY - A tolerance ring has a band ( | 12-23-2010 |
20100321832 | TOLERANCE RING ASSEMBLY - A tolerance ring has a band with outwardly extending corrugated protrusions forming waves that engage an outer surface of a shaft. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to a bore of a housing to assist during assembly. | 12-23-2010 |
20100138005 | PROCESS CONTROL OF TOLERANCE RINGS - A method of process control including constraining a tolerance ring relative to one of an inner and an outer component. The tolerance ring including an annular band of resilient material having a plurality of projections projecting radially therefrom. Additionally, the method includes moving the other of the inner or outer component with respect to the constrained tolerance ring so as to compress the projections of the tolerance ring between the inner and outer components, and continuing movement of the inner or outer component, respectively, beyond the projections. The method further including measuring a force required for continuing movement, and using the force for process control. | 06-03-2010 |
20100120543 | COMBINATION MOUNTING RING - A combination mounting ring of resilient material, for connecting a shaft within a bore of a housing, has a hollow cylindrical part having radially extending projections. This part is for locating between the outer surface of the shaft and the inner surface of the bore, the radially extending projections being under compression and thus securing the shaft within the bore. The combination mounting ring further has an axial spring element extending radially inward from the cylindrical part and having two portions at different axial positions. The axial spring element is for locating between the shaft and a body axially displaced from the shaft, and serves to minimize axial movement of the shaft within the bore of the housing. The axial spring element may either be an annular part or a tab extending from an axial edge of the cylindrical part. | 05-13-2010 |
