Abstract:
1. A transfer guide for use with a high-speed power transmission, comprising; a transmission chain travelling at a fixed first speed; said transmission chain includes rollers having radii; said chain and said rollers have an inner circumferential side and an outer circumferential side; a sprocket rotating at a fixed angular speed and moving said transmission chain at a second fixed speed; a travel limiting guide pressing said inner circumferential side of said chain and said roller such that said chain and said rollers are positioned to enter said sprocket and a transfer guide; said rollers of said transmission chain being meshed with said sprocket; a curved track; said curved track cancels any change in speed of said rollers of said transmission chain; said chain moving polygonally after said rollers of said chain mesh with said sprocket; said rollers spaced apart at desired chain pitches; said outer circumferential side of said chain being open; said curved track includes an outer guide for engaging said inner circumferential side of said rollers; wherein said curved track is formed by two continuous arc-shaped curves, and, said arc-shaped curves have a common inflection point, and, said outer guide and said travel limiting guide are movable and press on said rollers of said chain enabling rollers of different radii to be used.
