Problems solved by technology
Obviously, the transmission device with single speed ratio cannot adjust the output speed of the output device, so it cannot adapt to the change of working conditions, so that the prime mover cannot work at the maximum efficiency, resulting in waste of energy; while the transmission device with double speed ratio It can adjust the output speed of the output device, but it can only have two outputs, so it cannot adapt to any working environment, and it will also cause waste of energy, and it also requires manual adjustment of the speed ratio, which affects work efficiency

The invention discloses a transmission device. The transmission device comprises a guide piece, a driving shaft, a driven shaft, transmission wheels, a wheel carrier and an eccentric press piece, wherein the driving shaft can rotate relative to the guide piece; the driven shaft can coaxially rotate relative to the guide piece together with the driving shaft; the transmission wheels can rotate relative to the guide piece; the wheel carrier is used for supporting rotating shafts of the transmission wheels; the eccentric press piece eccentrically presses the wheel carrier to enable the rotating shafts of the transmission wheels to move along a rotation axis parallel to the driving shaft; the driving shaft further comprises a first contact part used for driving the transmission wheels to rotate; the driven shaft further comprises a second contact part used for enabling the driven shaft to be driven by the transmission wheels; at one side of the rotating shafts of the transmission wheels, the first contact part is in contact with the transmission wheels; at the other side of the rotating shafts of the transmission wheels, the second contact part is in contact with the transmission wheels; and the guide piece further comprises a guiding part used for guiding the wheel carrier to move along the rotation axis parallel to the driving shaft during movement of the wheel carrier. The transmission device can realize stepless speed regulation.
Description
technical field [0001] The invention relates to a power tool, in particular to a power tool and a transmission device thereof. Background technique [0002] A power tool generally includes a prime mover, a transmission device and an output device, wherein, in order to increase the output torque of the output device, the transmission device can also reduce the rotation speed of the output device relative to the output rotation speed of the prime mover. Existing power tools usually use single-speed or double-speed transmissions for power transmission, and the two-speed transmissions also need manual switching to adapt to changes in working conditions. Obviously, the transmission device with single speed ratio cannot adjust the output speed of the output device, so it cannot adapt to the change of working conditions, so that the prime mover cannot work at the maximum efficiency, resulting in waste of energy; while the transmission device with double speed ratio The output spee...
