Abstract
A sprocket for an inverted tooth chain includes at least one and typically first and second resilient cushion rings for adapted to be engaged by the guide links of an associated inverted tooth chain. The sprocket is usable with conventional inverted tooth chains and/or with a new inverted tooth chain that includes guide links for each row of the chain.
Claims19
A sprocket for an inverted tooth chain, said sprocket comprising:
- a hub;
- a plurality of teeth projecting radially outward from said hub and defining a ring that extends circumferentially around said hub, each of said teeth connected to adjacent teeth by a root surface and each of said teeth separated from adjacent teeth by an open tooth space;
- a first cushion ring connected to said hub on a first axial side of said ring of teeth, said first cushion ring comprising a plurality of first compression pads, said first compression pads located adjacent first axial faces of said plurality of teeth, respectively, each of said first compression pads comprising a first outer face adapted to engage guide links of an associated inverted tooth chain;
- and,
- a second cushion ring connected to said hub on a second axial side of said ring of teeth, said second cushion ring comprising a plurality of second compression pads, said second compression pads located adjacent second axial faces of said plurality of teeth, respectively, each of said second compression pads comprising a second outer face adapted to engage guide links of an associated inverted tooth chain.

An inverted tooth chain drive system comprising:
- a sprocket comprising:
- (i) a plurality of teeth separated by tooth spaces;
- and, (ii) at least one resilient cushion ring located adjacent said teeth;
- an inverted tooth chain engaged with said teeth of said sprocket, said inverted tooth chain comprising guide links in contact with said at least one resilient cushion ring.

An inverted tooth chain drive system comprising:
- a sprocket comprising:
- (i) a plurality of teeth separated by tooth spaces;
- and, (ii) first and second cushion rings located respectively adjacent first and second axial sides of said teeth;
- an inverted tooth chain engaged with said sprocket and comprising a plurality of links interconnected in an endless series, said links comprising alternating first and second link types wherein:
- said first link type comprises:
- (i) an aligned plurality of inside links each comprising first and second toes located in said tooth spaces of said sprocket;
- and (ii) first and second inside guide links between which said aligned plurality of inside links are located, said first and second inside guide links located respectively adjacent said first and second axial tooth faces and respectively engaging said first and second cushion rings;
- said second link type comprises first and second outside guide links located respectively adjacent said first and second axial tooth faces and respectively engaging said first and second cushion rings.

An inverted tooth chain comprising:
- a plurality of links interconnected in an endless series, said links comprising alternating first and second link types wherein:
- said first link type comprises:
- (i) an aligned plurality of inside links each comprising first and second toes adapted for receipt in tooth spaces of an associated sprocket;
- and, (ii) first and second inside guide links between which said aligned plurality of inside links are located, said first and second inside guide links at least partially overlapping said first and second toes and a space defined between said toes, and said first and second inside guide links adapted to receive a tooth of the associated sprocket there between;
- said second link type comprises first and second outside guide links adapted to receive a tooth of the associated sprocket there between.
