A traction machine for an elevator wherein a reduction gear for the traction machine rotatably mounts a first and second parallel spaced shafts such as an output and intermediate shafts inside the gear box by the wall of the gear box. First and second rotors such as helical gears are fixed on the shafts so as to mesh with each other, and at least one of the shafts has each end supported by the wall through a support element which includes first and second support members that are respectively rotatably supported by their outer and inner cylindrical peripheries, 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 eccentrically formed the inner cylindrical periphery is adapted to be secured to the wall of the gear box with the relative rotational position 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 rotors. |
