Abstract: A gear reduction mechanism includes a gearbox housing, a first gear having a first axis of rotation about a first shaft and the second gear having a second axis of rotation about a second shaft. The first and second gears are rotatably mounted in a gearbox housing so that the first and second gears mesh with each other such that the first axis of the first gear is substantially perpendicular to the second axis of the second gear. The gear isolator assembly is preferably disposed within the gearbox housing about the second gear for reducing noise generated between the first and second gears during operation of the mechanism.

Abstract: A method and apparatus for determining a pinion bearing move to correct pinion-to-gear alignment based on pinion null t overcoming the aforementioned drawbacks are provided. Using a realistic visual representation of a gear to pinion mesh showing pressure angles of the gear and pinion as well as the angle of the pinion down from the mill center line allows for a quick and accurate determination of a pinion bearing to align a pinion-to-gear assembly move. Using temperature differential data of the pinion under load conditions, the present invention allows for an easy and efficient means of determining a pinion bearing move to align a pinion-to-gear assembly without requiring complicated manual calculations or data input to a computer program. Furthermore, the present invention is lightweight and portable thereby avoiding the drawbacks often associated with handheld electrical devices and laptop computers.

Abstract: A screw drive with rolling elements, optionally a ball screw drive, includes a screw spindle with a spindle axis and a double nut running on the screw spindle, with two separately formed single nuts which are substantially rigidly joined in the direction of the axis of the spindle. In order to set a desired play or bias relative to the screw spindle, the two single nuts can be turned continuously about the axis of the spindle relative to each other and fixed in any relative rotary position corresponding to the desired play or bias. According to the invention, a first of the two single nuts or an intermediate element joined thereto and arranged between the two single nuts has at least one peripheral section pressed into an associated aperture in one of the single nuts. In one embodiment, the intermediate element is an annular disk that is arranged orthogonally to the spindle axis.

Abstract: A nut member which is rotated by power transmission from a motor in a rack housing is supported by a thrust bearing fitted and fixed in a first housing having an integrally formed fixing section for fastening to a vehicle body so that the nut member cannot move in both directions along an axial direction. Thrust loads applied in both directions to the nut member with the conversion of rotation into movement of a steering shaft in an axial direction are carried by the first housing through the thrust bearing. The structure of the connection section of the first housing and second housing is simplified, and the housing is fixed in a stable manner to prevent deterioration in steering feeling.
