Torque tool
摘要:
The torque tool comprises a torque converter including three planet carriers which encase three planetary gears. Each of the three planetary gears includes a sun gear and three planet pinions. Each of the three planet carriers has an input disc-shaped plate, directed towards an input shaft of the torque tool and an output disc-shaped plate directed towards an output shaft of the torque tool. The input and output shafts constitute the main shafts of the torque tool. Two of the three planet carriers, which are next to the input shaft, have their output disc-shaped plates extending into sun gears with which they form unitary structures. A stepped pin is centrally disposed in a needle bearing of a first sun gear adjacent the input shaft and extends through sliding bearings located in the following sun gears. A first large diameter of the stepped pin is commensurate with an interior diameter of the needle bearing and a second small diameter of the stepped pin is commensurate with interior equal diameters of the sliding bearings inserted in the following sun gears. The planet pinions of one of the three planet gears, which is adjacent to the output gear, arc each provided with a multiplicity of roll needles closely spaced together, the multiplicity of roll needles being inserted between each of the at least three planet gears and an axle for supporting.
