Abstract
This invention relates to a guide bar for a drive chain, provided with two orifices for passage of a pintle pin, each orifice being substantially triangular in shape, with substantially identical edges, in the form of arc of circle and concave. The bar is provided with a recess which extends, from an outer edge of the bar, in the direction of an opposite edge, between the afore-mentioned orifices. The bar comprises, on either side of the recess, two series of two convex edges in the form of an arc of circle, each of these convex edges being centred on the geometrical centre of one of the concave edges of a triangular orifice.
Claims22
Guide bar for a drive chain, said bar being provided with two spaced orifices for passage of a pintle pin, each orifice being substantially triangular in shape and defined by three substantially identical edges, each in a form of an arc of circle and concave, said bar being provided with a recess intermediate said orifices which extends from a first outer edge of said bar in a direction toward an opposite edge of said bar which is between said orifices, wherein said bar comprises, on either side of said recess, two series of two convex edges each in a form of arc of circle, each of said convex edges being centered on a geometrical center of one of said concave edges of an adjacent orifice.
