Document Type and Number:
Japanese Patent JP6621856
Kind Code:
B2
Abstract:
A method is provided for producing chain link plates for a plate link chain with alternating inner chain links and outer chain links, where the contour of the chain link plates has several punch sections and two face side and rear side contact sections which, after punching out the punch sections from the sheet metal strip provided, are first connected to complementary contact sections of adjoining chain link plates and separated in a subsequent separation cut. Further provided are bush or roller chains with outer chain link plates thus produced and a corresponding chain drive for an internal combustion engine with such a bush or roller chain. The method comprises the steps of: providing a sheet metal strip, punching out the punch sections of the chain link plates from the sheet metal strip, where a further rear side contact section, in addition to the face side contact sections, is respectively connected at the head portions of the chain link plates to a complementary contact section of adjoining chain link plates, and separating the face side contact sections and the rear side contact sections of the head portions of the chain link plates by way of a substantially waste-free separation cut.
