Abstract
A compactor includes a plate, a frame coupled to the plate, and an exciter assembly coupled to the plate and including an exciter shaft, an exciter pulley on the exciter shaft, and an eccentric weight on the exciter shaft. The compactor also includes a motor coupled to the frame and having an output shaft and a drive pulley on the output shaft, a belt wrapped around the exciter pulley and the drive pulley at a minimum tension value for transferring torque from the drive pulley to the exciter pulley, causing it to rotate, and a sensing circuit configured to detect if the tension in the belt is below the minimum tension value.
Claims20
A compactor comprising:
- a plate;
- a frame coupled to the plate;
- an exciter assembly coupled to the plate and including an exciter shaft, an exciter pulley on the exciter shaft, and an eccentric weight on the exciter shaft;
- a motor coupled to the frame and having an output shaft and a drive pulley on the output shaft, the motor output shaft being separate and distinct from the exciter shaft;
- a belt wrapped around the exciter pulley and the drive pulley at a minimum tension value for transferring torque from the drive pulley to the exciter pulley, causing it to rotate;
- and
- a sensing circuit configured to detect if the tension in the belt is below the minimum tension value.
An outdoor power equipment comprising:
- a drive assembly including a drive shaft;
- a working assembly including a driven shaft separate and distinct from the drive shaft;
- a belt operatively coupled to the drive assembly and to the working assembly, the belt configured to transfer torque from the drive shaft to the driven shaft;
- and
- a sensing circuit configured to detect if an amount of tension in the belt is below a minimum tension value,
- wherein the sensing circuit indirectly determines the amount of tension in the belt.
An outdoor power equipment comprising:
- a drive assembly including a drive shaft;
- a working assembly including a driven shaft separate and distinct from the drive shaft;
- a belt operatively coupled to the drive assembly and to the working assembly, the belt configured to transfer torque from the drive shaft to the driven shaft;
- and
- a sensing circuit configured to detect an amount of tension in the belt and to provide an indication to an operator of the outdoor power equipment if the amount of tension in the belt is below a minimum tension value.
