  • the present invention relates generally to the reworking of wheels on a rail vehicle, and more particularly to an apparatus for reworking worn wheel rims of wheels on a rail vehicle. Still more specifically the invention relates to reworking which is carried out with the wheels on the vehicle.
  • the type of apparatus capable of providing for reworking of the rail wheels while the same are on the rail vehicle may be two-fold, that is there are two basic different types.
  • One of these provides for centering of the wheels on dead centers or in axle bearings, and the other type does not utilize centers and the wheels with their flanges still being worked are supported on drive rollers with their circumferential surfaces uncentered.
  • centrically adjusted wheels obtain, when turned, centrically turned circumferential surfaces.
  • Those adjusted by means of dead centers further make possible a proper setting of the tools, the prerequisite for this being that devices are provided for aligning the centers with respect to their height, because the centers are height adjustable.
  • the setting of the tools is problematical because it is not possible to take measurements for the starting position.
  • the wheel rims on the circumference of the wheel flange copy the accuracy of these aforementioned surfaces of rotation for those of the profile which is to be newly produced.
  • the trueness of revolution is dependent exclusively upon the starting or initial profile.
  • the worn wheels are eccentric and are measured too large by double this eccentricity.
  • the rolling surfaces are not round but, because of braking action and the like may be polygonal and that on the measuring surfaces rust, dirt or welds may be present which in turn disadvantageously influence the accuracy of measurement.
  • the gauge measurement is one of the most important wheels profile measurements but has considerably tighter tolerances than the so-called AR measurements, the measurements of the wheel spacing from the center between the wheels, so that when reworking is carrier out in accordance with what has been set forth above, the gauge measurements often cannot be maintained, particularly if one wheel has the proper lateral spacing from the center between the two wheels and only the otherwheel is shifted on the axle. ln this case the total deviation from the intended gauge measurement falls to only one of the wheels and the result may be that of the flange of this one wheel is weakened to an impermissible extent.
  • an object of the present invention to provide an apparatus for reworking worn wheel rims of wheels on a rail vehicle.
  • the rail which is supported so that its wheels have freedom to rotate, and the transversely spaced wheels which are also are mounted on a common axle are also engaged and supported.
  • the wheel flanges are then turned until they are centrical and cylindrical and the diameter of the thus turned wheel flanges is thereupon measured.
  • the desired new circumferential configuration of the wheel rims is determined as a function of measurement taken with reference to the axis of rotation of the wheels and with reference to the diameter of the wheel flanges, and the wheel flanges are then turned to the thus determined new circumferential configuration.
  • the measurement taken on this surface guarantees that during the subsequent profile renewal the wheel will turn true-to-round in the uncentered wheel flange support, in accordance with the already mentioned factor that the new rotational diameter is copied by its support surface.
  • the present invention provides for an improved measurement of the wheel circumference and therefore for a more accurate diameter measurement because the surface on which measurements are taken is round and central, as well as being clean, free of grease and free of all faults.
  • This newly turned surface also constitutes a proper measuring basis for measuring the worn spots of the vehicle rim and it permits an even distribution of deviation from the gauge dimension to both wheels as well as an adherence to the proper gauge dimension.
  • a further factor to be considered is the fact that rail vehicle speeds are being increased in accordance with modern requirements. This, in turn, requires a greater precision in manufacturing the components, particularly the drive components of such vehicles, and especially in the manufacture of the wheels.
  • an extremely high accuracy of 0.3% diameter deviation of all wheels of an entire group of sets of wheels can be achieved without difficulty.
  • accuracy was not attainable on the type of machines used for turning the wheels when they are not removed from the vehicle.
  • the accuracy achieved under the circumstances could not be achieved in this manner, and on the other hand the accuracy achievable depends even more than on other types of machines on the accuracy with which measurements can be taken.
  • an apparatus according to the present invention comprises a separate measuring station which is arranged ahead of the actual reworking station because then the measuring of the nextfollowing set of wheels can be carried out while the preceding set is being reworked. This results in a considerable increase in the productivity of these machines. Multiple reworking of any set of wheels is reduced to the irreducible minimum.
  • the present invention may of course be carried out at the reworking station itself, also.
  • Devices for producing the measuring basis, that is turning machines, are already present so that only the necessary measuring devices need be supplied in order to obtain the advantages according to the present invention.
  • two measuring sliders are provided which are shiftable parallel to the axle on which a set of wheels is mounted, and these are shifted by means of a diflerential gear in mutually opposite direction, being provided with abutments which abut against the inner side of the respective wheels.
  • This arrangement makes it possible to obtain an advantageous and precise axial setting of both measuring supports on which the turning and measuring devices are mounted and in particular each measuring slider may be provided with an indicator which shifis against a stationary scale and there indicates deviations of the spacing of the inner sides of the two wheels (AR measurement) from the nominal center of the distance between the two wheels, and such deviations can be corrected if necessary.
  • Known measuring wheels for measuring the circumference are used as diameter measuring devices, and these are applied to the newly turned measuring surfaces on the wheel flanges and thus produce precise measurements because the measuring surface is round, centric and clean as well as free of form deviations.
  • holders are provided either on the measuring supports or adjacent them, and are formed with guides in which sliders are shiftable which are in turn provided with abutment rollers.
  • Feeler rollers are mounted on the sliders and are under spring biassed pressure, being deflectable with a scale being provided on the slider which indicates their deflection.
  • This device provides for a measurement of the wear of the wheel rim from the measuring basis, that is from a basis whose diameter is known because of the previous measurement. It furthermore provides a measurement of the distance to the rolling surface nominal profile, so that the feeler directly indicates the radial depth of cut adjustment while the new wheel rim diameter for supports with positioning devices can be calculated.
  • an abutment which is tiltable away is provided, together with a marker which are adjustable with reference to a diameter scale provided on the adjustable cam-carrier transverse slider or table.
  • the diameter scale of each support is set to the exact diameter value of the turned measuring basis on the wheel flange and the measured value of the largest profile wear is readjusted on the basis of this scale so that the machine is immediately set for the new turning diameter.

I, is moved on the rails 2 until it is above the pit 3 and is there lifted by hydraulic or other piston arrangements 4 which engage under the axle supports 5, until the wheel rims 6 of the two wheels are slightly spaced above the rails 2, for instance approximately 20 mm.
  • the wheels can be rotated by the friction rollers 7 which contact their rolling surface and which are mounted in rockers 8. These latter are tumable in the gear housing I0 about the axis of the tri-wheel 9 and are provided with gears 11 and I2 transmitting the drive to the friction rollers 7.

  • Both of the members 21 are linked via the spindles 27 and 28 with one another, and of the spindles 27 and 28 one is provided with a right-hand thread and the other with a left-hand thread.
  • a nut 29 which connects both spindles and a bevel gear 31 is provided on the nut 29 and is shiftable via a tongue and groove arrangement on the nut 29.

  • the measuring devices must be adjusted with reference to the set.
  • the nut 29 is turned via the bevel gear 31 and the hand wheel 32 and both of the members 21 are moved axially outwardly until first one abutment 91 contacts the associated inner wheel side.
  • the hand wheel 32 now only causes movement of the other member 21 until its abutment 91 also contacts the associated inner wheel side.
  • the housing 30 shifts in the same direction half the distance which is traversed by the other still moving member 21.
  • both abutments 91 abut against the respective inner wheel sides, the members 21 are properly positioned with reference to the wheels. Their spacing can be read off the scales 93.
  • both abutments 91 When both abutments 91 are in contact with their respective wheels the abutments are turned through 90 out of engagement with the wheel, and the housing 30 is clamped by known non-illustrated means to the measuring means 17.

Now the members 21 are retracted by turning the hand wheel 32, and such retraction is towards the middle until they reach the abutments 53. Thereupon the transverse members 23 are adjusted for instance by 1 mm by turning of the hand wheel 26 and thereby a measuring surface of approximately l mm width is produced on the wheel flange. After the customary clamping of the supports by means of non-illustrated but very well known clamping arrangements, the wheel flange is manually turned by turning of the hand wheel 32.
  • This basis must now be measured which is accomplished in known manner by a measuring wheel 37 of 100 mm diameter which is applied to the measuring surface 38 and whose rotations during precisely one turn of the wheels of the set 1 can be measured and read off the counter 41.

  • the measured diameter values of the measuring basis are now entered in a record, and from these values are deducted on the one hand double the flange height (2 X 27 54 mm) les l mm each of material removed by milling equals 52 mm, and on the other hand the measured wear of the wheel rim rolling surface, that is double the depth of material removal.
