Abstract

The invention relates to an articulated chain comprising at least an inner connecting plate (1), an outer connecting plate (2), a sleeve (3) and a pin (4) forming a chain joint, wherein the external connection is A labyrinth sealing device is arranged between the plate (2) and the inner connecting plate (1), the labyrinth sealing device comprises at least one raised part (41) and at least one groove (42), wherein the at least one raised part (41) and at least one A groove ( 42 ) is formed in length (LN) or depth (TN) between 10% and 50% of the corresponding average web thickness (D), and wherein the labyrinth seal is designed such that it is In the event of overloading, the path of the force flow within the articulated chain is partially changed by the labyrinth surface formed by the at least one projection (41) and the at least one groove (42).

Description

technical field [0001] The present invention relates to an articulated chain. Background technique [0002] An articulated link chain, in particular a sleeve chain, essentially consists of two elements which are arranged endlessly on one another. These elements are also referred to as inner and outer link plates. The outer link plates generally comprise two outer connecting plates, which are fixedly connected to each other by two pins. The inner link plate is usually composed of two inner connecting plates and two sleeves, which respectively form a chain joint with the pins of the adjacent outer link plates. These joints enable the joint chain, for example, to be wound around sprockets in the drive train. [0003] An important criterion for the use of an articulated chain is its transmittable tensile force. In principle, corresponding transmittable tensile forces are achieved, for example, by the material selection, heat treatment and material thickness of the individual...
