摘要： A power tool having a drive component and a housing. In one form, the drive component can be a transmission having a planetary stage with planet gears rotatably mounted on pins of a planet carrier. The pins are spaced circumferentially around the planet carrier such that each pair of adjacent pins is spaced apart by a spacing angle. At least two different spacing angles are employed. In another form, the drive component is selected from at least one of a motor, a transmission and a clutch and the housing is configured with first and second housing components and at least one set of mating conically-shaped features that can cooperate to align the housing components to an axis.

摘要： A power tool with a housing, a transmission and a switch mechanism. The switch mechanism has an actuator, a rail, a switch and first and second springs. The actuator is non-rotatably but slidably coupled to the housing for movement along a longitudinal axis of the transmission between a plurality of positions to selectively engage one or more members of the transmission at each of the positions such that the transmission operates in one of a plurality of different overall speed ratios. The rail is fixedly coupled to the actuator and is received through the switch such that the switch is slidably mounted on the rail. The first and second springs are configured to bias the switch relative to the actuator in different directions.
