Abstract

The figure illustrates a chain or belt tensioner comprising a molded tractor guide 1 having a hollow recess in one end, into which a tensioner bearing block 2 is inserted on top of a spring 3 disposed in molded guide 1. When belt or chain 4 is passed around the top of tensioner 2, the spring 3 is partially compressed to exert a constant stretching or tensioning force on the belt or chain 4, which is driven by the drive sprocket or roll 5 at the lower end of belt 4. This device maintains the belt or chain tension throughout the working life of the part without need for adjustment, and thereby reduces maintenance downtime.
