Abstract
For enhanced durability, a traveling guide shoe for a roller chain has a cross-sectional shape with a base slide guide surface 12 which engages only the bottoms of the side link plates of the chain on a chain-incoming-end, a projecting rolling guide surface 13 which engages only the rollers of the chain at an intermediate portion of the shoe. The base surface 12 and the projecting surface 13 are connected with each other through a continuous transfer surface 13.
Claims13
A traveling guide shoe for use with an associated roller chain comprising transverse rollers rotatably mounted between transversely-spaced parallel longitudinal link plates, said shoe having an incoming end, an exit end, and a shape for pressure-bearing contact with the associated roller chain adapted to move into contact with the shoe at said incoming end and to move out of contact with the shoe at said exit end, a longitudinal base slide guide surface at at least one of said incoming end and said exit end, adapted to engage the associated roller chain, and adapted to bear only on the chain link plates of the associated roller chain, a longitudinal projecting rolling guide surface adapted to engage the associated roller chain and adapted to bear only on the transverse chain rollers of the associated roller chain, said rolling guide surface being positioned at an intermediate portion of the shoe between said incoming and exit ends, and being spaced from said at least one of said ends to provide a space between said rolling guide surface and said at least one end,
- said base surface and said projecting surface being connected with each other through a continuous transfer surface in said space.
