Although balancer shaft drives generally bridge only small distances, they should contain guide rails that calm the chain in the areas between the sprockets. Furthermore, depending on the type of tensioner (linear or rotary tensioner), tensioning rails or pads are used to transmit the force of the tensioning element to the chain. The chain slides with little friction and wear over a plastic sliding layer. Both the available space and the loads acting on the rail are decisive in determining the material to be used for the load-bearing substructure of the rail.
The following options are available:
Finite element calculations and related analyses can be used to achieve maximum rigidity while maintaining minimal cost and design space. Mounting on the engine is matched individually to the conditions present.
