Abstract
Link plates of a silent chain are produced by first shaving the inner surfaces of the connecting pin holes, the sprocket tooth-engaging surfaces, and the backs of the link plates, and then forming dimples on those surfaces by shot-peening.
Claims8
A method of making a silent chain comprising the steps of:
- providing link plates having sprocket tooth-engaging surfaces and pin-receiving holes, said pin-receiving holes having inner surfaces;
- providing connecting pins;
- subjecting said inner surfaces of said pin-receiving holes in said link plates to shot peening and thereby forming dimples on said inner surfaces;
- arranging said link plates in interleaved rows;
- and
- interconnecting said interleaved rows by inserting one of said connecting pins through each of the dimpled pin-receiving holes;
- in which the shot peening of the inner surface of each pin-receiving hole is preceded by shaving of said inner surface.

- providing link plates having sprocket tooth-engaging surfaces and pin-receiving holes, said pin-receiving holes having inner surfaces;
- providing connecting pins;
- subjecting said inner surfaces of said pin-receiving holes in said link plates to shot peening and thereby forming dimples on said inner surfaces;
- arranging said link plates in interleaved rows;
- interconnecting said interleaved rows by inserting one of said connecting pins through each of the dimpled pin-receiving holes;
- and
- forming dimples on said sprocket tooth-engaging surfaces;
- in which the formation of dimples on each said sprocket tooth-engaging surface by shot-peening is preceded by shaving of said sprocket tooth-engaging surface.
A method of making a silent chain comprising the steps of:
- providing link plates having sprocket tooth-engaging surfaces, back surfaces, and pin-receiving holes, said pin-receiving holes having inner surfaces;
- providing connecting pins;
- subjecting said inner surfaces of said pin-receiving holes in said link plates to shot peening and thereby forming dimples on said inner surfaces;
- arranging said link plates in interleaved rows;
- interconnecting said interleaved rows by inserting one of said connecting pins through each of the dimpled pin-receiving holes;
- and
- forming dimples on the back surfaces of said link plates by shot peening;
- in which the formation of dimples on each said back surfaces by shot peening is preceded by shaving of said back surfaces.
A silent chain comprising rows of link plates having sprocket tooth-engaging surfaces and pin-receiving holes, and connecting pins extending through said pin-receiving holes in the link plates and connecting the link plates in interleaved relationship, in which each said pin-receiving hole has a dimpled inner surface formed by shot-peening, and in which each said dimpled inner surface of a pin-receiving hole is formed by subjecting a pin-receiving hole to shaving before shot-peening.
A silent chain comprising rows of link plates having sprocket tooth-engaging surfaces and pin-receiving holes, and connecting pins extending through said pin-receiving holes in the link plates and connecting the link plates in interleaved relationship, in which each said pin-receiving hole has a dimpled inner surface formed by shot-peening, in which each said sprocket tooth engaging surface is a dimpled surface formed by shot-peening, and in which each said dimpled sprocket-tooth engaging surface is formed by subjecting a sprocket tooth engaging surface to shaving before shot-peening.
A silent chain comprising rows of link plates having sprocket tooth-engaging surfaces and pin-receiving holes, and connecting pins extending through said pin-receiving holes in the link plates and connecting the link plates in interleaved relationship, in which each said pin-receiving hole has a dimpled inner surface formed by shot-peening, in which each link plate has a dimpled back surface formed by shot peening, and in which each said dimpled back surface of a link plate is formed by subjecting a back surface of a link plate to shaving before shot-peening.
