Abstract
The drive system is used for spinning, twisting or false-twisting machines. The spindles are driven by a tangential drive belt which is tensioned between a drive roll and a tensioning roll. The tensioning roll is mounted by a lever to pivot about a fixed axis. In addition, a rotatable axle is mounted about the fixed axis in order to drive additional working elements of the machine. The tangential belt is maintained under constant tension by a biasing means which biases the lever about the fixed axis.
Claims12
A drive system for a spindle frame of a spinning machine having a plurality of spindles arranged in a row, said drive system comprising
- a drive roll,
- a tensioning roll,
- a tangential drive belt tensioned between said drive roll and said tensioning roll for engaging and driving the spindles,
- a first axle secured to said tensioning roll for rotation therewith about a first axis,
- a second axle rotatably mounted about a fixed second axis,
- a lever journalled on said first axle and said second axle,
- means secured to said lever for biasing said lever to pivot about said second axis in a plane parallel to said tangential drive belt,
- drive transmitting means disposed between said first and second axles for rotating said second axle off said first axle, and
- a drive means interconnected to said second axle for driving additional working elements of the spinning machine.
In combination with a spindle frame having two rows of spindles, a drive system for each said row of spindles, each said drive system comprising
- a drive roll,
- a tensioning roll,
- a tangential drive belt tensioned between said drive roll and said tensioning roll for engaging and driving the spindles,
- a first axle secured to said tensioning roll for rotation therewith about a first axis,
- a second axle rotatably mounted about a fixed second axis,
- a lever journalled on said first axle and said second axle,
- means secured to said lever for biasing said lever to pivot about said second axis in a plane parallel to said tangential drive belt, and
- a drive transmitting means disposed between said second axle and first axle for rotating said second axle off said first axle.
