摘要： A telescopic steering column assembly includes at least one support bearing assembly that comprises an inner bearing race which is located on the steering shaft, an outer bearing race that is located on an inner face of a shroud, and a set of ball bearings that are located between the inner bearing race and the outer bearing race and are free to roll along bearing surfaces defined by the bearing races. Each of the bearing races comprises a pair of annular bearing race parts, defining a circumferentially extending bearing surface arranged coaxially and spaced apart from each other axially such that varying the spacing between the two parts varies the effective radius of the bearing race. The support bearing assembly further comprising an inner annular support sleeve that is located between the inner bearing race and the inner shaft, an outer annular support sleeve that is located between the outer bearing race and the shroud, and a biasing means that in use applies an axially directed thrust between a first one of the annular support sleeves and one of the respective bearing race parts, and the bearing assembly is arranged such that the axial thrust applied by the biasing means is converted into a radial thrust that is applied to the inner bearing race and outer bearing race to force them into engagement with the inner and outer sleeves respectively.

摘要： A motor shaft of an electric motor is produced by producing and interconnecting a first module and an additional module of the motor shaft. The first module of the motor shaft and/or the additional module of the motor shaft is or are provided with a module-end connection element by cold forming and/or by warm forming and/or by hot forming a base module. The first module of the motor shaft produced in this way and the additional module of the motor shaft produced in this way are then interconnected by joining the module-end connection elements on both ends. A motor shaft produced according to this method is formed of a correspondingly configured first module and a correspondingly configured additional module.

摘要： Example torque tube assemblies for use with aircraft high lift devices are described herein. An example apparatus includes a spline coupling having a first yoke, a sliding splined shaft having a second yoke and a torque tube having a first end and a second end opposite the first end. A first fitting with a third yoke is coupled to the first end of the torque tube, and a second fitting with a fourth yoke is coupled to the second end of the torque tube. The third yoke is coupled to the first yoke to form a first U-joint, and the fourth yoke is coupled to the second yoke to form a second U-joint. The spline coupling is to be coupled to a first high lift device drive shaft and the sliding splined shaft is to be coupled to a second high lift device drive shaft.

摘要： The rolling surface of each ball and a radially outside surface of the inside guide plate are in contact with each other only at two circumferentially set-apart inside contact parts. The rolling surface of each ball and a radially inside surface of the outside guide plate are in contact with each other only at two circumferentially set-apart outside contact parts. At a state after the extensible rotation transmission shaft is assembled, at least the inner surface of the inner-side concave groove is elastically deformed more radially inwards than a state before the assembling, thereby preloading the respective balls.

Solution: an extendible working machine is provided with a rotation/drive section, a working section, and a rod section which connects the rotation/drive section and the working section, transmits rotational force to the working section, and can be extended and retracted. The rod section is provided with a tube body which can be extended and retracted, and also with a shaft body which extends in the axial direction within the tube body and which can be extended and retracted together with the tube body. The tube body is provided, with an outer tube and with an inner tube which can move within the outer tube. The shaft body is provided with a drive shaft which is supported within the outer tube by bearings in a rotatable manner, and also with a pipe shaft which is supported within the inner tube in a rotatable manner. Helical grooves are formed in the surface of the drive shaft, and the drive shaft is connected to the pipe shaft such that the pipe shaft can move in the axial direction along the outer surface of the drive shaft and such that the rotation of the drive shaft is transmitted to the pipe shaft.

摘要： A rotation transmitting apparatus includes a first shaft on which multiple external teeth are formed so as to be arranged in a circumferential direction, and a second shaft in which multiple internal teeth are formed so as to be arranged in the circumferential direction, the second shaft being fitted to the first shaft so as to be slidable relative to the first shaft in the axial direction and so as to be engageable with the first shaft in a rotational direction through the use of the external teeth and the internal teeth. A protrusion is formed on the tooth flank of one of the external tooth and the internal tooth, the protrusion being projected toward the corresponding tooth flank of the other of the external tooth and the internal tooth. The protrusion is made of a resin that is more elastically deformable than the tooth flank.
