摘要： A power tool cooling system comprises a cooling fan disposed on a motor in a position between the upper field coil and the lower commutator. A transmission housing encapsulates the transmission mechanism. During operation, the fan is driven by the motor and draws air axially through the motor and expels the air radially outwardly through holes in the outer housing of the motor. This causes air to be drawn in through the air vents formed on the top of a tool housing, in the side of the housing and between the housing and a battery pack. The cool air flows outside of the transmission housing, but inside the tool housing such that air does not pass through the transmission mechanism. A plurality of motor openings are also formed in the outer housing of the motor to enable cool air to pass into the motor to cool the motor.

摘要： A transmission housing for a hammer drill 320 is formed from three housing portions. A generally L-shaped first housing portion 380a accommodates a spindle 348, a hollow piston 358, the respective spindle and hollow piston drive mechanisms and a mode change mechanism. The first housing portion 380a is mounted to a second housing portion 380b such that a first O-ring 382a is trapped between the two portions to prevent the ingress of dust. The second housing portion 380b holds the lower part of the transmission mechanism inside the first housing portion 380a. The second housing portion 380b forms a motor output aperture 390 for enabling the motor output shaft 336 to engage the transmission mechanism. A third transmission housing portion 380c is mounted to the front of the first housing portion 380a such that spindle 348 projects out of the third transmission housing portion 380c. A second O-ring 382b seals the join between the first and third transmission housing portions 380a, 380c.
