Steering Device

Номер: US20120193901A1
Принадлежит: NSK LTD

A steering device contains a rolling bearing that axially supports a steering shaft to allow rotation, and whose upper column and lower column engage along the axis in a sliding motion in order to provide improved steering wheel operating stability during high-speed driving. The elastic force of an O-ring tightens the outer circumferential surface of a female steering shaft against the cylindrical surface of a bushing. A specific frictional force therefore occurs between the cylindrical surface of the bushing and the outer circumferential surface of the female steering shaft so that handling stability of the steering wheel during high-speed driving is improved. Moreover, vehicle vibrations are prevented from being conveyed to the steering wheel by the O-ring crushed due to the pressing force of the inner circumferential surface of the first lower column and that absorbs the vibration of the female steering shaft.

To solve both axial and rotational constraint problems in turbochargers with rolling element bearings (REBs), a REB sleeve or outer race is mounted to the bearing housing in a way that is not axially and radially rigid, thus allowing for oil damping films both radially and axially. At the same time, the REB sleeve or outer race is held so that the REB sleeve or outer race does not rotate relative to the bearing housing. This dual purpose is achieved using an anti-rotation ring and a damping ring. The anti-rotation ring includes at least one anti-rotation feature for engaging the bearing housing and at least one anti-rotation feature for engaging the REB cartridge, preventing rotation of the REB cartridge sleeve or outer race. The damping ring axially locates the REB cartridge and dampens axial movement and cushions axial thrust. 1.

A gas turbine shaft bearing system (bearing and/or seal component) service method and service tool that applies biasing force between a gas turbine shaft and a bearing system component supporting the shaft, so that the bearing system component can be removed or installed. The bearing system service tool is coupled directly to the bearing system component and the shaft, preferably without the need for external fixtures. A biasing force generator, such as a hydraulic unit applies a force on the bearing system component to cause component movement on or off the shaft. Counter-biasing forces are resisted by the fixed position turbine shaft. By exerting biasing force directly between the turbine shaft and bearing system component the service tool can be constructed of smaller, man portable components that are more easily maneuvered within relatively confined turbine service spaces, which are common in field installations.
