A method and a device for reducing the vibrations of a control chain in a camshaft drive of an internal combustion engine. At least one engine parameter is measured that is indicative of the vibrational state of the engine. The at least one engine parameter is used to determine the vibrational state and to adjust the tension of the control chain. Thus, the built-up of resonances and of strong vibrations may be avoided.

A method for joining a plate chain link is to be improved, in which at least one plate is connected to at least one bolt by way of a pressing and aligning process. This is achieved by the measures that the bolt is centered in relation to a main chain axis by the simultaneous active application of symmetrical clamping forces to the faces and the least one plate is pushed by a joining lift relative to the bolt into a position symmetrical to the main chain axis. Furthermore, the invention relates to a device for carrying out the method.

Method for joining a flat-link articulated chain element

A plate chain comprising outer and inner chain links which are interconnected at joint places formed as slide bearings, with each joint place formed by a sleeve of the inner chain link and by a pin bolt of the outer chain link which rotates in the sleeve substantially about its own axis. The wear characteristics of the resulting joint places are improved. At least one portion of the lateral surface of the pin bolt and an associated portion of the inner surface of the sleeve have a different circumferential contour at the pulling side, so that the pin bolt is supported on the sleeve at least two circumferentially spaced-apart points or lines of contact at the pulling side. A method for producing chain members includes forming a sleeve with a joint trough.

Plate chains with wear-resistant chain joints

A conveyor apparatus having a conveyor chain and at least one supporting arm used for attaching thereto objects which are to be conveyed. The supporting arm has one of its ends connected to the conveyor chain via an overload protection means. The overload protection means has a tilting joint which is provided between the supporting arm and the conveyor chain and permitting reversible tilting of the supporting arm relative to the conveyor chain in response to a predetermined load. In the structural design of the conveyor apparatus the tilting joint is acted upon by a helical tension spring.
