C hain drives are used to transmit forces and motion between parallel shafts.
They are used whenever spindle/shaft spacings have to be bridged which
cannot be achieved with gear wheels or with belt drives because of
unfavorable space or transmission conditions. Chain drives are preferred to as
“positive envelope drives”. One or more sprockets are “enveloped” by an endless
chain. They offer slip-free power transmission. If properly designed, they combine the
advantages of a positive belt-drive with those of a positive gear wheel drive. Any
shocks, which can endanger service reliability, are largely absorbed by chain drives,
unlike spur gears, where elastic couplings have to be used. The mechanical efficiency of
chain drives is ŋ = 0.93 to 0.99.
A variety of types of sprocket chains are used as drive chains or load chains for power
transmissions, such as:
Heavy duty roller chains; closed pitch or precision roller chains; flat top crate conveyor
chains; ‘duplex’ or ‘triplex’ roller chains; malleable iron link chains; inverted-tooth or
silent chains.
Because of its versatility, the roller chain should be seen as the most impo
