Abstract
An pneumatic tensioner apparatus is disclosed, the apparatus including: a main drive belt; a chuck assembly, suspended from the main drive belt, having a spinning member and a drive contact portion; a first frictional drive belt in a first track, the first frictional drive belt in contact with the drive contact portion operative to spin the chuck assembly; and a first tension adjusting device having at least one pneumatic tension adjustment member operative to apply pressure to the first frictional drive belt tangentially to the drive contact portion.
Claims17
An pneumatic tensioner apparatus, comprising:
- a main drive belt;
- a chuck assembly, suspended from said main drive belt, having a spinning member and a drive contact portion;
- a first frictional drive belt in a first track, said first frictional drive belt in contact with said drive contact portion operative to spin said chuck assembly;
- and
- a first tension adjusting device having at least one pneumatic tension adjustment member operative to apply pressure to said first frictional drive belt tangentially to said drive contact portion.
An pneumatic tensioner apparatus comprising:
- a main drive belt;
- a chuck assembly, suspended from said main drive belt, having a spinning member and a drive contact portion;
- a first frictional drive belt in a first floating track, said first frictional drive belt in contact with said drive contact portion operative to spin said chuck assembly;
- a first tension adjusting device having at least one pneumatic tension adjustment member operative to apply pressure through said first floating track to said first frictional drive belt tangentially to said drive contact portion;
- a second frictional drive belt in a second floating track in contact with said drive contact portion and disposed on an opposite side of said chuck assembly to said first frictional drive belt and moving in a direction opposite said first frictional drive belt;
- and
- a second tension adjusting device having at least one pneumatic tension adjustment member operative to apply pressure through said second floating track to said second frictional drive belt tangentially to said drive contact portion;
- wherein said first and second pneumatic tension adjustment members each comprise a flexible elastic tube filled with a compressed substance, and wherein said pressure applied by said tube is adjusted by varying the amount of said compressed substance in said tube.
