Link chain with inclined plate backs

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.

1. A link chain comprising:
alternating inner and outer chain links connected to one another by a chain articulation and 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 the at least one inner plate and the at least two outer plates to one another, each chain link pin is arranged in a rotationally fixed manner in a pin opening of the associated outer plates and extends through a link opening of the associated inner plate to form the chain articulation, wherein the inner and/or outer plates have plate backs that extend between center lines of the link opening of the at least one inner plate or the pin openings of the at least two outer plates for contacting a tensioning rail or a guide rail, wherein at least a forward region of the plate backs in the direction of motion of at least a part of the inner and/or outer plates includes a length that extends at a constant angle to a plane projected between the center lines of the pin openings or link openings, and the forward region of the plate backs is inclined towards the plane when traced in the direction of motion, and wherein the plate backs further include a parallel portion with a straight length, the straight length of the parallel portion being parallel to the plane projected between the center lines of the pin openings or link openings.
