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 butterfly valve for controlling gas flow is disclosed. The butterfly valve may include a valve body, the valve body defining a bore and a shaft configured for rotatable motion with respect to the valve body and including a shoulder. The butterfly valve may further include a disk housed within the bore, operatively coupled with the shaft, and configured to control gas flow through the bore based on a rotational position of the shaft relative to the valve body. The butterfly valve may further include a ball bearing operatively coupled with the shaft and including a ball and a race. The butterfly may further includes a spring configured to provide an axial force on the shaft, the axial force configured to press the shoulder of the shaft against the race of the ball bearing to prevent an outer edge of the disk from contacting an inner wall of the bore.

摘要： A fuel-saving apparatus using a variable preload of vehicle bearings is provided. The fuel-saving apparatus includes a housing that supports a driving shaft of a vehicle, a bearing that is mounted in the housing and rotatably supports the driving shaft, and a variable preload unit that is provided at the housing or a side adjacent to the housing and applies a preload to an outer wheel or an inner wheel of the bearing. The fuel-saving apparatus using such a variable preload may reduce a driving load acting on the driving shaft by a fixed preload acting by the bearing, thereby reducing the driving load of an engine and saving fuel.

摘要： An electric power steering device includes a worm which is swingably connected to the rotation shaft of an electric motor through a joint. A first end portion and second end portion of the worm are supported by a first bearing and a second bearing, respectively. A pair of elastic members elastically urge the worm to an axial neutral position. An annular leaf spring which is held by a housing urges the second end portion toward a worm wheel through the second bearing. A synthetic resin member having a sliding contact surface which is in contact with the leaf spring is integrally disposed on the second bearing.
