    In an underfloor wheel set lathe for reprofiling the wheel tyre contours (16, 17) of railway wheel sets (5), having four driven friction rollers (18, 19, 20, 21) two rotational supports (30, 31) and a machine control (52) it being possible to press the friction rollers in pairs against one wheel tyre contour (16, 17) each of a wheel set (5), a slipping of the friction rollers on the wheel tyre contours is avoided in that a device (54, 55, 56, 57) for determining the slip occuring between a friction roller and a wheel tyre contour is provided which controls the advancing speed of the rotational supports (30, 31) as a function of the determined slip. <IMAGE>

    The invention relates to a machine tool industry, in particular to machine tools for turning wheel sets in order to restore the profile of railway wheels.
    The purpose of the invention is to increase the productivity of machining by eliminating the slip of the wheelset during turning when the rotation of it is transmitted from the drive friction rollers.
    Fig. 1 shows a machine for turning wheel pairs without rolling out with a pair of wheels, a longitudinal section, partially showing the vehicle body and foundation, a section; Fig. 2 shows a section A - A in Fig. 1.
    The machine for turning wheel pairs without rolling out is mounted on several support elements 1 and 2, which are adjustable in height and in the horizontal plane, which are located on foundation 3.
    A pair of wheels 4 mounted on a rail vehicle 5 is fixed by its axle boxes 6 and 7 with the help of two support devices 8 and 9 and two clamping devices 10 and 11.
    Support 8 and 9 and clamping 10 and 11 devices are equipped with hydraulic cylinders 12-15.
    With both profiles 16 and 17 of the tires of the wheelset 4, two friction rollers 18-21 installed with the possibility of rotation, each of which are driven by the engine 22-25, interact.
    Each friction roller 18 - 21 is equipped with a drive 26 - 29 rotation.
    The machine contains two rotary calipers 30 and 31, which are equipped with longitudinal 32 and 33 and transverse 34 and 35 carriages.
    Each of the longitudinal carriages 32 and 33 is driven from the engine 36 and 37, and each of the transverse carriages 34 and 35 is driven from the engine 38 and 39.
    Each of the transverse carriages 34 and 35 carries a turning tool 40 and 41, which is adjustable in the longitudinal (double arrow 42) and transverse (double arrow 43) feed directions.
    The motors 22-25, which are driven by the friction rollers 18-21, and the motors 36-39 of the swivel supports 30 and 31 are connected by wires 44-51 to the machine control system 52. The control system 52 is powered from the network 53.
    The machine is provided with a comparator unit 54 for detecting slippage that occurs between the friction roller 20 and the band profile 17.
    The comparator unit 54 has a sensor 55 for measuring the peripheral speed Va of the friction roller 20, a sensor 56 for measuring the peripheral speed VB of the profile 17 of the band.
    Comparison unit 54 by lines 57.- 59 is connected to sensors 55 and 56 and to control system 52. Sensor 55 is a rev counter associated with engine 24.
    The sensor 56 has a measuring disk 60 which is pressed against the inner side 61 of the profile 17 of the band. The pressing of the measuring disk 60 is carried out by the movement mechanism 62 mounted on the lifting device 63. The lifting device 63 is screwed to the bed 64 of the rotary support 31.
    When idling the machine, the circumferential speed Va of the friction roller 20 is equal to the peripheral speed VB of the profile 17 of the bandage, since the frictional forces transmitted to the wheel set 4 are very small.
    Comparison unit 54 takes this into account by forming a ratio

    q circumferential speed Va
     the processing time of the wheelset 4, the comparator unit 54 detects slippage between the drive friction roller 20 and the band profile 17 by forming a ratio.
    Vai-Vci VBI
    qi VaiVai
    Depending on the qi value, the comparator unit 54 controls the feed rate of the rotary support 30 and 31.
    If, for example, when machining a wheel pair, qi decreases, then comparator 54 prevents the friction rollers 18-21 from slipping along profile 16 and 17 by reducing the feed rate. As qi increases, comparator unit 54 increases the feed rate, thereby increasing the efficiency of machine tool turning for wheel sets.
