Abstract
A compactor including a plate, an electric motor coupled to the plate and including a motor shaft configured to rotate about a rotational axis, and an exciter coupled to the plate and configured to vibrate the plate in response to receiving torque from the electric motor. The exciter includes an exciter shaft and an eccentric mass attached thereto. The compactor additionally includes a battery configured to provide power to the electric motor, and a gear train to transfer torque from the motor shaft to the exciter shaft. The gear train permits the exciter to be driven at a rotational speed that is faster or slower than a rotational speed of the electric motor.
Claims16
A compactor comprising:
- a plate;
- an electric motor coupled to the plate and including a motor shaft configured to rotate about a rotational axis;
- an exciter coupled to the plate and configured to vibrate the plate in response to receiving torque from the electric motor, wherein the exciter includes an exciter shaft and an eccentric mass attached thereto, wherein the exciter shaft is configured to receive torque from the motor shaft to rotate the eccentric mass to impart vibration to the plate, and wherein the exciter shaft is parallel with the rotational axis;
- a battery configured to provide power to the electric motor;
- and
- a gear train to transfer torque from the motor shaft to the exciter shaft, wherein the gear train permits the exciter to be driven at a rotational speed that is faster than, slower than, or a same speed as a rotational speed of the electric motor.
A compactor comprising:
- a plate;
- an electric motor coupled to the plate and including a motor shaft configured to rotate about a rotational axis;
- an exciter coupled to the plate and configured to vibrate the plate in response to receiving torque from the electric motor, wherein the exciter includes an exciter shaft parallel with the rotational axis and an eccentric mass attached thereto;
- a battery configured to provide power to the electric motor;
- and
- a gear train rotationally coupling the motor shaft and the exciter shaft, wherein the gear train transfers torque from the electric motor to the exciter, causing the eccentric mass to rotate.
A compactor comprising:
- a plate;
- an electric motor coupled to the plate and including a motor shaft configured to rotate about a rotational axis;
- an exciter coupled to the plate and configured to vibrate the plate in response to receiving torque from the electric motor, wherein the exciter includes an exciter shaft coaxial with the rotational axis and an eccentric mass attached thereto;
- and
- a gear train positioned on the rotational axis and rotationally coupling the electric motor and the exciter, wherein the gear train and the exciter are located on one side of the electric motor, and wherein the gear train is configured to transfer torque from the electric motor to the exciter, causing the eccentric mass to rotate.
