Abstract
A table saw includes a lower guard assembly, a first airflow fan, a motor, and a drivetrain system. The lower guard assembly has a dust exhaust chute and is configured to at least partially enclose a lower portion of a saw blade. The first airflow fan is positioned in the lower guard assembly and is configured to produce a first airflow directed through the lower guard assembly toward the dust exhaust chute. The motor is configured to rotationally drive an output shaft, and the drivetrain system connects the output shaft to the first airflow fan and the saw blade to enable the motor to rotationally drive the first airflow fan and the saw blade simultaneously.
Claims15
A table saw comprising:
- a lower guard assembly including a dust exhaust chute, the lower guard assembly being configured to at least partially enclose a lower portion of a saw blade;
- a first airflow fan positioned in the lower guard assembly and configured and arranged to produce a first airflow directed through the lower guard assembly toward the dust exhaust chute;
- a second airflow fan positioned in the lower guard assembly and configured to produce a second airflow directed through the lower guard assembly toward the dust exhaust chute, the first and second airflows forming a combined airflow directed toward the dust exhaust chute;
- a motor configured to rotationally drive an output shaft;
- and
- a drivetrain system connecting the output shaft to the first airflow fan and the saw blade to enable the motor to rotationally drive the first airflow fan, the second airflow fan, and the saw blade simultaneously.
