FITTING CHAINS TO SPROCKETS
The chain should be fitted so that the hook opening is outwards.
Chains may be driven in either direction, but will wear less if the hook trails. Exept when used in fine grained abrasive materials where the hook should lead.
SHAFT SPACING
Should be adjustable; or if not possible, a tensioner could be fitted in the application.
The use of connection links simplifies chain assembly in cases where the shafts are fixed or not adjutable.
SPROCKET BEARINGS
If two or more chains rusn parallel on one common shaft, the driven sprockets should be independently journal to avoid unnecessary stress in the chain.
CHAIN SPEED
The recommended speed is depended on the number of teeth on the sprockets. The table below shows the recommended maximum values.
SPROCKETS
Sprockets are avaliable for all chain sizes. The spockets listed below are avaliable
All raw material used as well as each stage of manufacture is carefully and continously controlled. Chains manufactured by Kohlswa are subjected to test loading, dimensional checks and optical inspection as a matter of routine. Futhermore, the extensive resources of the modern works laboratory are avaliable for steel analysis, hardness tests and ultimate strength tests. The recommended working loads on the preceding page have been chosen to allow for generous safety margins.
