10 SPECIAL - PURPOSE RAILWAY WHEEL LATHE Model 836M.0. APPLICATION Special-purpose wheel lathe, model 836M.0, is designed for machining new wheel sets and reprofiling worn- out tyres of wheel sets used in diesel and electrical locomotives, coaches and commuter trains with railroad gauge of mm and tread diameter mm. Wheel sets are machined by carbide tools made in SANDVIK-KOROMANT, Sweden. 2. DESIGN FEATURES Main assembly components of the lathe are: bed, spindle heads (LH & RH), reducer, drive motor of faceplate and spindle heads, carriages (LH & RH), jack, control panel. Configuration of the lathe is symmetric arrangement of the components in regard to middle line perpendicular to a centers line. Wheel set is loaded onto rollers of hydraulic jack by overhead crane to position below the center line 5-0 mm. Then, the spindle heads are brought together simultaneously to clamp a wheel set in quill centers. Further movement of spindle heads retracts the quills, and the driven jaws thrust against ends of wheels, thus transmitting a torque from the gearbox to a wheel set. Jaw plungers pockets on each faceplate are linked together. That allows to distribute a clamping force uniformly. Spindle speed control is infinitely variable by rotating a dial located on the control panel. After loading wheel set, reducer is to be switched from heads movement to faceplate rotation by the button on the lathe control panel. Thereafter, an operator manually sets templates in stand by position. Profile is to be machined in consequent scanning all along with straight- turning tools. Carriages are provided with bi-dimensional hydraulic servo system. Feed rate is controlled infinitely variable. Highly motorized, the lathe provides easy and convenient service. 3.
