ABSTRACT:
An impact mechanism, such as an impact wrench is provided and includes a motor, a shaft rotatable about an axis and coupled to the motor and having a first shaft groove with first and second axial ends and a hammer disposed about the shaft and having a first hammer groove. A ball is disposed in the first hammer groove and in the first shaft groove and couples the hammer to the shaft for relative axial and rotatable movement, with the ball moveable along the grooves. The wrench also includes a rotatable anvil for coupling to a load, a bias member resiliently biasing the hammer axially into engagement with the anvil and stop structure disposed along the shaft for engagement with the hammer to limit axial movement of the hammer away from the anvil so as to prevent the ball from contacting the second axial end of the first shaft groove.
