PARTICLE SEPERATION ASSEMBLY FOR POWER TOOL

摘要

A power tool is provided including a having a field case portion and a gear case portion, a motor disposed in the field case portion of the housing, a gear set disposed in the gear case portion of the housing and operatively connected to the motor via a motor spindle, a fan rotatably connected to the motor, a plurality of intake conduits disposed along the housing, and a particle separation assembly in fluid communication with the plurality of intake conduits. The particle separation assembly includes a baffle and a centrifugal chamber, where the baffle is operable to direct airflow from the intake conduits into the centrifugal chamber in a cyclonic path, and the centrifugal chamber includes a radial gap forming a particle dispersion port in the cyclonic path of the airflow to eject contamination from the airflow. Additionally or alternatively, the centrifugal chamber includes a plurality of air-directing fins arranged angularly to direct contamination from the airflow towards the particle dispersion port.
