Abstract
Official abstract text for this publication.
An apparatus ( 10 ) for imparting tension to multiple strands of an endless power transferring member loop ( 12 ) encircling a drive sprocket ( 14 ) and at least one driven sprocket ( 16 a, 16 b ). Two tensioning arms ( 18 a, 18 b ) are spaced apart and have guided movement relative to at least one fixed pin ( 26 ), and support inwardly facing shoes ( 20 a, 20 b ) with power-transferring-member-sliding faces ( 22 a, 22 b ). A link assembly ( 60 ) includes at least two link members ( 32 a, 32 b ) pivotally connected to one another at respective first ends ( 40 a, 40 b ). The connected first ends ( 40 a, 40 b ) are constrained for limited movement along a fixed slot ( 36 ) extending generally along a centerline of the power transferring member loop ( 12 ) between the drive sprocket ( 14 ) and the driven sprockets ( 16 a, 16 b ). The link members ( 32 a, 32 b ) are pivotally connected individually to opposite ends of the two spaced apart tensioning arms ( 18 a, 18 b ) at second locations ( 42 a, 42 b ).
First claim
Opening claim text (preview).
What is claimed is: 1. A tensioning system for imparting tension to an endless loop power transferring member encircling a drive sprocket and at least one driven sprocket comprising: a pair of tensioning arms, each tensioning arm having an arm movement guide mechanism, a link pivot and a shoe with a power-transferring-member-sliding face; at least two link members, each link member having a first end and a second end, each second end connected to corresponding link pivots of the…
