摘要
A rotary power tool operable in a first speed mode and a second speed mode comprising a motor shaft (6), a driveshaft (10) with an axis of rotation (42), a gear (24, 74) that is a component of a transmission (8) for transmitting torque from the motor shaft (6) to the driveshaft (10), a support member (48, 70), at least one bearing member (54, 76) which contacts the gear (24, 74), wherein the gear (24, 74), the support member (48, 70) and the at least one bearing member (54, 76) form an assembly that is in a first position along the axis of rotation (42) when the tool is operating in the first speed mode and is in a second position along the axis of rotation (42) when the tool is operating in the second speed mode, and wherein the at least one bearing member (54, 76) protrudes from the support member (48, 70) in the direction of the gear (24, 74) and rotates when the gear (24, 74) rotates.
