摘要： A drill includes a housing and a motor coupled to an output member by a transmission. The transmission can selectively couple the output member to an output spindle through a low speed output gear or a high speed output gear for rotating the output spindle at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch that limits the speed of the motor. A rotatably fixed hammer member and a rotatable hammer member can be mounted around the output spindle. A mode collar can be rotatably mounted on the housing and around the output member for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission operates in the high speed mode.

摘要： A multi-speed drill includes a housing with a motor including an output member. A constant mesh parallel axis transmission can be disposed in the housing and can include a high speed and low speed gears. A clutch member can be associated with the low speed gear. A conical spring can bias the low speed gear and the clutch member together for torque transfer up to a predetermined torque level. Above the predetermined level, cam surfaces between the low speed gear and the clutch member move them apart, thereby limiting torque transfer to the output spindle. In the high speed mode the torque transfer between the input pinion and the output spindle bypasses the clutch member. The maximum torque level capable of being generated at the output spindle in the high speed mode can be less than the predetermined torque level.
