Lıft-Centerıng System Wheel Lathe

The invention relates to wheel lathe with a lifting- centering system, intended for installation in a pit below the rail head in indoor heated rooms, and can be used for lifting and centering wheel sets and brake discs of rolling stock when processing surface rolling and with a maximum load of up to 40 tons per axle. In a wheel lathe containing a lift-centering system, including two symmetrically located balancers with spindle rollers, and two drive racks made with the possibility of vertical movement and impact on the balancers to transmit rotational motion to the wheel being processed, each rack is made in the form of a trapezoidal screw connected to the drive motor shaft , and installed on the specified screw by means of the internal thread of the quill, which is fixed against rotation and is provided from above with an end support with push rollers. The technical result consists in increasing the strength and expanding the possibilities of varying the processing modes due to the developed lifting centering system 4 fails, 6 pics. TR 2020 17159 U5
