A seat adjuster assembly includes an electric motor having an output shaft with a worm gear positioned in a gearbox, a spur gear meshing with the worm gear in the gearbox, a spindle shaft fixed to and driven by the spur gear coacting with a nut contained in a tube, and a linkage system connected to both a vertically movable upper vehicle seat part and a non-vertically movable lower vehicle seat part that positions vertically the upper vehicle seat part responsive to the position of the nut relative to the spindle shaft. At least one washer is provided on the spindle shaft. The spur gear is a plastic spur gear molded over the washer. A pair of leaf springs disposed in the gearbox bears against the spur gear and a wall of the gearbox.

The single-part chamber (4) of the pump (1) surrounds a motor rotor (5).

A power steering system with a circulating ball spindle mechanism, an extending element of the circulating ball spindle mechanism being support rotatably over a bearing and the bearing of the element making possible a swiveling motion corresponding to the direction of action of interfering forces.

The invention relates to an accessory gearbox capable of driving the accessory devices of a gas turbine engine, such as an aircraft engine. Said accessory gearbox includes a housing and a plurality of gear wheels having axes that are parallel to one another inside the housing. The housing includes a means for attaching the accessory devices to the wall of the housing and driving them, via the gear wheels, through openings in the wall of the housing. The gear wheels are supported in the housing by rolling-element bearings. Each rolling element includes a first ring that is stationary relative to the housing, and a movable ring, secured to the gear wheel, wherein at least one (110) of said gear wheels is supported by a single rolling element (120).

The invention provides a manual auxiliary support. Fixing bolts are arranged on the periphery under a base. A guide hole is vertically formed in the middle of the base. An ejector rod is arranged in the guide hole in a matched mode. A spring is arranged under the ejector rod. The ejector rod stretches out of the base from the guide hole. A clamping sleeve used for clamping an opening is also arranged in the guide hole. The ejector rod is installed in the clamping sleeve in a matched mode. A locking screw corresponding to the clamping sleeve is arranged on the side wall of the base. A positioning hole is formed in the side wall of the clamping sleeve. A fixing screw matched with the positioning hole is arranged on the side face of the base. A cover plate is arranged at the top of the base. The ejector rod stretches out of the cover plate. An adjustment bolt is arranged at the bottom of the spring. An air outlet is further formed in the position, on the lower portion of the ejector rod, of the side wall of the base. According to the manual auxiliary support, the ejector rod has a floating supporting effect relative to the spring, the locking purpose can be achieved manually through surface contact of the clamping sleeve, and convenience and rapidness are achieved; the manual auxiliary support is mainly used for designing clamps for poor-rigidity parts such as thin-walled parts and parts in irregular shapes, rapid fixing and installing are achieved, the structure is simple, and the manual auxiliary support is economical and practical.
