The present invention relates to a deceleration device for excavator auger.
The auger bucket deceleration device of the present invention, the housing, the planetary gear unit, is composed of the output shaft with respect to the speed reducing apparatus for an auger excavator for delivering the appropriate number of revolutions and torque for drilling soil and rock in the auger, the planetary gears unit, but a vertical connection to the reduction gear ratio is another multi-stage other planetary gear unit, that each stage of the planetary gear and the ring gear is made of upper and lower two-stage structure, respectively, each as the planetary gear and the ring gear and the same two-stage structure the speed varying means perimeter ring gear to the side and corresponding connection, wherein the planetary gear and the ring upper planet gear and meshing with the upper ring gear in accordance with the gear of the upper side to the operation of the speed varying unit of the two-stage structure through the pressure or the pressure release the upper ring to control the gear rotation of the reduced rotation and one for the number of stages: being made to rotate 1, on the other hand in accordance with the operation of the lower speed varying means lower ring the transfer gear with the functional upper planetary gears of the bottom and the lower side as all of the planetary gear is engaged or separated one for the number of stages: characterized in that configured to include a first rotation, the reduced rotation is made of the structure.
Therefore, in accordance with the present invention, thereby to slow down some or all of the planetary gear unit in accordance with the working environment should freely adjust the reduction ratio of the reduction gear and, at the same time, such that be provided with a different number of revolutions and the torque into a single auger excavator excellent there is an effect.
