Abstract
A drive assembly for a dual coacting roller machine having a driven sprocket mounted onto a first roller shaft, a drive sprocket mounted onto a second roller shaft, and a pair of idler sprockets connected by a belt to the driven sprocket and drive sprocket, wherein one of the idler sprockets is mounted onto a mounting bracket connected to the driven sprocket, such that repositioning of the driven sprocket relative to the drive sprocket produces a corresponding repositioning of the mounting bracket and idler sprocket, such that the tension on the belt remains essentially the same.
Claims18
A dual coacting roller machine, said roller machine having a first roller shaft and first roller and a second roller shaft and second roller mounted in parallel to define a gap between said first roller and said second roller, wherein said gap may be increased or decreased by repositioning said first roller shaft and said first roller relative to said second roller shaft and said second roller, said roller machine further comprising a drive assembly comprising:
- a drive sprocket connected to said second roller shaft, such that rotation of said drive sprocket rotates said second roller shaft and said second roller;
- power means for rotation of said drive sprocket;
- a driven sprocket connected to said first roller shaft, such that rotation of said driven sprocket rotates said first roller shaft and said first roller;
- a pair of idler sprockets;
- a fixed mounting bracket connecting said drive sprocket to one of said pair of idler sprockets, and an adjustable mounting bracket connecting said driven sprocket to the other of said pair of idler sprockets in a fixed spatial relationship, such that repositioning of said driven sprocket results in corresponding repositioning of said other of said pair of idler sprockets;
- a belt connecting said drive sprocket, said driven sprocket and said pair of idler sprockets, such that rotation of said drive sprocket results in rotation of said driven sprocket and said pair of idler sprockets;
- whereby repositioning said first roller shaft relative to said second roller shaft results in corresponding movement of said adjustable mounting bracket relative to said fixed mounting bracket.
A drive assembly for a dual coacting roller machine, said roller machine having a first roller shaft and a first roller and a second roller shaft and second roller mounted in parallel to define a gap between said first roller and said second roller, wherein said gap may be increased or decreased by repositioning said first roller shaft and said first roller relative to said second roller shaft and said second roller, and wherein said first roller shaft and said first roller relative rotate in a direction opposite to said second roller shaft and said second roller, said drive assembly comprising:
- a drive sprocket connected to said second roller shaft;
- a driven sprocket connected to said first roller shaft;
- a pair of idler sprockets;
- a belt connecting said drive sprocket, said driven sprocket and said pair of idler sprockets, such that rotation of said drive sprocket results in rotation of said driven sprocket and said pair of idler sprockets;
- and
- a mounting bracket connecting said driven sprocket to one of said pair of idler sprockets in a fixed spatial relationship, such that repositioning of said driven sprocket relative to said drive sprocket results in corresponding repositioning of said one of said pair of idler sprockets.
A dual coacting roller machine, said roller machine having a first roller shaft and a first roller and a second roller shaft and second roller mounted in parallel to define a gap between said first roller and said second roller, wherein said gap may be increased or decreased by repositioning said first roller shaft and said first roller relative to said second roller shaft and said second roller, and wherein said first roller shaft and said first roller relative rotate in a direction opposite to said second roller shaft and said second roller, and further comprising a drive assembly comprising:
- a drive sprocket connected to said second roller shaft;
- a driven sprocket connected to said first roller shaft;
- a pair of idler sprockets;
- a belt connecting said drive sprocket, said driven sprocket and said pair of idler sprockets, such that rotation of said drive sprocket results in rotation of said driven sprocket and said pair of idler sprockets;
- power means to rotate said drive sprocket;
- and
- a mounting bracket connecting said driven sprocket to one of said pair of idler sprockets in a fixed spatial relationship, such that repositioning of said driven sprocket relative to said drive sprocket results in corresponding repositioning of said one of said pair of idler sprockets.
