A traction machine for an elevator is disclosed wherein a reduction gear for the traction machine rotatably mounts a first and second parallel spaced shafts such as an output and intermediate shafts therein by the wall of the gear box, the shafts fixedly securing thereon a first and second rotors such as helical gears, respectively, so as to mesh with each other, and at least one of the shafts having each end supported by the wall through a support element comprising a first and second support members that are rotatably supported by the outer and inner cylindrical peripheries thereof, respectively, the eccentric inner cylindrical periphery formed in the outer cylindrical periphery of the first support member being adapted to rotatably support the end of the shaft, whereas the outer cylindrical periphery of the second support member within which is formed the inner cylindrical periphery eccentrically thereto is adapted to be secured to the wall of the gear box with the rotational position relative thereto as well as to the first support member being suitably adjusted for the purpose of reducing or adjusting the backlash or the mesh of the rotor. |
