  • Publication number: 20110033149
    Abstract: A double roller bearing which has an outer and inner bearing ring and ball rollers, which have lateral faces and are arranged next to each other in rows, arranged between the bearing rings. The rollers roll in raceways incorporated into the inner face of the outer bearing ring and outer face of the inner bearing ring. The raceways run in parallel and have pressure angle axes that are pitched at a pressure angle relative to a bearing radial axis. The rollers have a distance relative to each other which excludes mutual frictional contacts. For this purpose, the distance of the pressure angle axes of the raceways is enlarged and both rows of rollers are guided in separate bearing cages, while the raceway of the rollers of the row with the larger reference circle arranged on the inner bearing ring has a one-sided axial extension using the distance.

  • Patent number: 7882815
    Abstract: A hydraulic cam follower for simultaneous actuation of several equal-acting gas-exchange valves, especially for a tappet pushrod valve train of an engine, includes an outer part, whose base forms a cam contacting surface, and from whose head hollow-cylindrical guides extend in the same number as the valves in a direction towards the base. A housing of a hydraulic play compensation element is provided in each guide and sits with its bottom side on an inside of the bottom of the outer part. A concentric pressure piston is guided in a borehole starting from a head end of each housing so it can move axially. A non-return valve is located at a bottom-side base of the piston and a high-pressure space is formed axially between the base and the bottom side of the housing. A reservoir for hydraulic medium is formed between the base and a head end of the piston.

  • Publication number: 20110028254
    Abstract: A belt drive is provided, especially a timing-belt drive for an internal-combustion engine, with a driving gear of a driveshaft, at least one driven gear of a driven shaft, and a belt means, wherein the driving or the driven gear imparts additional irregularity to the belt drive due to its noncircular shape and its phase position, which leads to stable running of the belt means. A noncircular gear that can be mounted easily and in phase, as well as with a fixed position, is realized in that the driving or driven noncircular gear has in its in-phase rotational position a rotationally fixed connection to its driving or driven shaft.

  • Publication number: 20110028226
    Abstract: A universal joint or a pivot pin cross with a universal joint pivot pin. The universal joint pivot pin is fastened a bearing bush seal and absorbs an axially directed force. A universal joint is to be provided which is simple and can be manufactured inexpensively, which makes no compromises with respect to the sealing effect. For this purpose, a bearing bush seal is provided which deflects an axially directed force into a radial direction. This makes an axial stop at the universal joint pivot pin unnecessary. Moreover, pivot pin are accomplished in a single manufacturing step.
