Abstract
This disclosure relates to methods and apparatuses of employing belts for an angular drive. A twisted geometry is applied to a first free span of the belt. A sheave supports the first free span of the belt at a first extremity of the first free span and sheave is at least one of positioning and orienting the rotating sheave or the driven sheave so as to misalign a geometric centerline of the first free span of belt at a given fleet angle with respect to a second extremity of the first free span.
Claims10
An apparatus for employing a belt for an angular drive, the apparatus comprising:
- a belt having a free span configured in a twisted geometry;
- at least one of a freely rotating sheave and a driven sheave supporting a first end of the free span of belt;
- and
- a sheave support assembly configured to position at least one of the freely rotating sheave or driven sheave so as to misalign a geometric centerline of the free span of the belt configured in the twisted geometry, the free span of belt misaligned at a given fleet angle with respect to a stationary sheave positioned at a second end of the free span of belt, the sheave support assembly configured to retain the at least one of the freely rotating sheave or driven sheave at the given fleet angle to maintain the misalignment.
