Abstract
A multiple strand drive chain for transmitting power from toothed sprockets to an endless belt constructed of toothed links. The strand which cooperates with the toothed links has a plurality of spaced rollers, with alternate rollers, which have a first predetermined diameter, being constructed of a deformable, resilient material. The intervening rollers, which have a smaller diameter than the first predetermined diameter, are constructed of a substantially non-deformable, rigid material. The deformable rollers normally share the driving load in a substantially uniform manner, but as the chain wears the sharing becomes disproportionate. The non-deformable rollers greatly extend chain life by limiting the maximum driving load placed on any one deformable roller.
