Claims19
A vibratory screen comprising first and second sidewalls and at least a first classifying deck supported between the sidewalls, and an eccentric shaft operably coupled to the sidewalls in order to vibrate the sidewalls and the first classifying deck, the vibratory screen comprising:
- a motor;
- a belt driven by said motor, said belt operably coupled to the eccentric shaft;
- a belt tensioning assembly configured to adjust a tension in said belt, the tensioning assembly comprising:
- a support bracket;
- a belt engagement assembly operably engaging said belt;
- a torsion spring, said torsion spring operably coupling said belt engagement assembly to said support bracket, said torsion spring mounted to a spring support;
- an adjustment arm operably coupled to said support bracket and said spring support, a position of said adjustment arm being adjustable by a user, wherein adjustment of said position of said adjustment arm adjusts a tension in said torsion spring;
- and
- a fastener removably coupling said adjustment arm, wherein tightening of said fastener secures said position of said adjustment arm.
A tensioning assembly for use with a vibratory screen comprising first and second sidewalls and at least a first classifying deck supported between the sidewalls, and an eccentric shaft operably coupled to the sidewalls in order to vibrate the sidewalls and the first classifying deck, a motor, a belt driven by the motor and operably coupled to the eccentric shaft, wherein the tensioning assembly is adapted to adjust a tension in the belt, the tensioning assembly comprising:
- a support bracket;
- a belt engagement assembly configured to operably engage the belt;
- a torsion spring, said torsion spring operably coupling said belt engagement assembly to said support bracket, said torsion spring mounted to a spring support;
- an adjustment arm operably coupled to said support bracket and said spring support, a position of said adjustment arm being adjustable by a user, wherein adjustment of said position of said adjustment arm adjusts a tension in said torsion spring;
- and
- a fastener removably coupling said adjustment arm, wherein tightening of said fastener secures said position of said adjustment arm.
