摘要： A tensioning or guide rail for a chain drive, in particular for a chain drive of an internal combustion engine, comprises two spaced-apart contact sections and one non-contact section arranged therebetween, the contact sections each having a sliding surface which is adapted to be brought into contact with a chain, and the non-contact section interconnecting the two contact sections as a support structure. Such a rail is to be configured such that the installation space available can be utilized more advantageously. To this end, the support structure of the non-contact section comprises an opening extending continuously from a front to a rear of the tensioning or guide rail and separating the contact sections provided with the sliding surfaces. The invention also relates to an endless drive of the type in question.

摘要： A link chain has alternating inner and outer chain links connected by a chain articulation, having a direction of motion, wherein each inner chain link has at least one inner plate, and each outer chain link has at least two outer plates and two chain link pins connecting these plates, each pin being rotationally fixed in a pin opening of the associated outer plate and extending through a link opening of the associated inner chain link to form a chain articulation. The inner and/or outer chain links have plate backs contactable with a tensioning rail or guide rail. A forward region of the plate backs in the direction of motion of a part of the inner and/or outer plates extends at an angle to a plane projected between the center lines of the pin openings or link openings. The vertex of the angle points away from the direction of motion.

摘要： A rocker joint for a bush chain or roller chain, comprises a bush having a through-passage running along the bush longitudinal axis, a first rocker surface formed in the through-passage, and a pin arranged in the through-passage of the bush and which has a second rocker surface formed thereon. A chain comprises inner and outer chain links, which are offset relative to each other, the inner and outer chain links being connected by rocker joints, each of which comprises a bush and a pin. A friction-reducing joint and a chain with reduced friction and less wear are provided, and thus a reduced CO2 emission of the associated internal combustion engine, the chain being stable and easy to produce. This is achieved in that the bush is configured as a straight circular cylinder in which the through-passage is arranged in the bush eccentrically with respect to the longitudinal axis of the bush.
