摘要： One aspect of the invention includes a speed changing device which can be switched from a high-speed low-torque output state to a low-speed high-torque output state. In the high-speed low-torque state, a second stage internal gear rotates together with a first stage carrier. The low-speed high-torque output state is caused as the second stage internal gear is disconnected from the first stage carrier so as to be restricted from rotating. The timing of resetting the speed changing device is shifted relative to the timing of stopping the electric motor by an OFF operation of the switch lever with a delay mechanism, so that the second stage internal gear is engaged with the first stage carrier after the rotation through inertia is stopped, whereby its impact is reduced.

摘要： In a speed change device of an electrical power tool, a reset arm is provided separately from a switch lever, which arm is operated by a reset motor. Due to tilting motion of the reset arm, a lock ring can be returned to an unlocking position in which a second stage internal gear can be rotated, so that the speed change device can be rest to a high speed low torque mode.

摘要： A switchable gear in a handheld power tool has at least two gear stages which are to be engaged via an adjustable switching member, the switching member being in a latched position via a retaining element fixedly held against a housing in a first gear stage. Furthermore, a spindle for receiving a tool may be driven via an axially spring-loaded gear wheel, the gear wheel being axially supported on the retaining element on the side opposite the switching member.

摘要： An electrical power tool may include a speed change device that is capable of being automatically changed as an external torque applied to a spindle is increased. In a high speed low torque mode before an automatic speed change, an extremely high output rotation speed in which an output torque sufficient to progress the screw tightening operation to the end cannot be generated is set. The output rotation speed before the speed changing operation is set in a range of about 4.5 times to 6.0 times the output rotation speed after the speed changing operation. Thus, in an initial stage of the screw tightening operation, it is possible to quickly performing the operation with a high speed rotation than ever before. Conversely, after the automatic speed change, it is possible to complete the screw tightening operation with the large output torque.

摘要： The present invention has disclosed a variable speed tool and a variable speed control method. The tool includes a switch; a gearbox housing; a motor; an outputting shaft; a multistage transmitting gear train and a gearshift ring which are mated with the motor and the outputting shaft, the gearshift ring having inner teeth; a gearshift fork mated with the gearshift ring; a tension spring arranged between the gearbox housing and the gearshift fork; and a torque sensing ring provided with a sliding groove in which the gearshift fork is movably disposed. When the load of the outputting shaft has reached to a predetermined value, the torque sensing ring makes the gearshift fork move axially in the sliding groove under the action of the tension spring, thus bringing the gearshift ring to move axially. The variable speed tool of the present invention may automatically adjust the rotating speed and the torque of the outputting shaft according to a variation of the load torque.

摘要： A transmission assembly is powered by an electric motor and includes a transmission having an outer ring gear, a connector moveable relative to the outer ring gear between a first position, in which the connector is rotatable with the transmission in response to torque received from the motor, and a second position, in which the connector and the outer ring gear are non-rotatable, and a control mechanism operable to detect the operating current of the motor and compare the operating current to a threshold current. The control mechanism is operable to move the connector from the first position to the second position in response to the motor operating current exceeding the threshold current.
