专利说明:

The invention of OTHocHtcH is to a machine tool industry and can be used for turning wheel sets without rollout to re-profile the tire on the wheel set of railway rolling stock,
The aim of the invention is to reduce the processing time by transferring the full frictional force to the wheelset.
Fig, 1 schematically shows a machine dp turning wheel pairs with a partial section along the base; Fig. 2 shows a horizontal projection of a machine for turning wheel sets, with a wheel set depicted in phantom lines; on fig.Z - section aa on fig, 1; Figures 4-9 show different phases of the reprofiling of the wheelset.
The wheel turning machine I, which is rigidly connected to the base 2, is used for the re-profiling of the wheel brace along profile 3 and 4 of the wheel set 5 mounted on the railway rolling stock 6
The machine for turning wheel pairs 1 has two unified units 7 and 8, each of which contains two friction rollers 9, 10 and 11, 12, two oscillating drives 13, 14 and 15, 16 and two rotary 17, 18 and 19, 20 movements for friction rollers 9, 10 and 11, 12, pressure 21, 22 and support 23, 24 devices for axle boxes 25 and 26 of wheel set 5, and also rotary supports 27 and 28,
. The machine for turning wheel pairs I includes a running track 29 with two rolling 30 and 31 and pitched 32 and 33 rails, as well as two flip rails 34 and 35 to overlap the rolling 30 and 31 and pitched rails 32 and 33,
The transfer arms 34 and 35 are disposed in the direction of the running track 36 so that they can be removed from the working area of the rotary support 27 and 28,
The friction rollers 9-12 are driven into rotation by four hydraulic motors 37-40,
Each friction roller 9-12 has rotation axes 42-45 parallel to the axis of the wheelset 41;
Each rotary actuator 17-20 is supported by swinging arms 46-49a.
The swing arms .46-49 can be rotated around a swing axle axis 50-53, which is parallel to the axis of the wheelset 41 and, accordingly, is articulated with a drive of the oscillating motion 13-16.
When installing the wheel set 5 on the wheel turning machine
it first rolls along rolls 30 and 31 and reversible 34 and 35 rails in the direction of the track 36 to the middle of the machine 54. Then the wheel pair 5 due to the deflection of the friction rollers 9-12 in the direction of the axis of the wheel pair 41 is slightly elevated above the level of the path.
In the elevated position of the pair of wheels 5 alternately from the work area
calipers 27 and 28 are shifted reversible, rails 34 and 35 in the direction of the running track 36 and both box boxes 25 and 26 are fixed by clamping 21 and 22 and supporting 23 and 24 device-.
(Fig. 1 and 3) ..
In the positions of the wheel pair 5 shown in FIGS. 1 and 3, the re-profiling of the tires on profile 3 and 4 is carried out by means of the swivel supports 27 and 28, each of which
equipped with turning tools 55 and 56.
Of the four friction rollers driven 9-12, two of them 9 and 10 with their circumferential surface 57 and 58 relate to the left tire 59, and two 11 and 12 to the circumferential surface .. 60 and 61 to the right tire.
Each circumferential surface 57, 58, 60, and 61 should be understood as the working surface of the cut cone.
The circumferential surfaces 60 and 61 of the friction rollers 11 and 12 are approximately twice the circumference of the surfaces 57 and 58 of the friction rollers 9 and 10.
The circumferential surfaces 57 and 58 of the friction rollers 9 and 10 are located at some distance 62 from the center of the wheel set 63.
The circumferential surfaces 60 and 61 of the friction rollers 11 and 12 are located from the middle of the wheelset 63 at a distance 64, which is greater than the distance 62, as is the width 65 of the side surfaces 60 and 61 less than that
with a width of 66 circumferential surfaces 57 and 58.
Due to the different removal of 62 and 64 circumferential surfaces 57, 58 and 60, 61 from the center of the wheelset 63
it is ensured that of the four friction rollers 9-12 at least two of them can transmit the full friction force to the wheel pair (Figs. 5-9),
If the circumferential surfaces 57, 58 and 60, 61 are removed at different distances from the center of the wheelset 63, then of the four friction rollers 9-12, at least three of them can transmit the full friction force to the wheelset 5,
During the reprofiling process, each of the turning tools 55 and 56 cuts a new profile of band 67 and 68 (Fig. 4-9).
After the re-profiling of the tires on the profile 3 and 4 swivel calipers
27 and 28 are alternately outputted from the working 2o wheelset, each fricking zone, reversing rails 34 and 35 are moved into the zone between the rolling 30 and 31 and the pitched 32 and 33 rails and the wheelset 5 due to the deflection of the friction rollers 9-12 lowered onto the rails 34 and 35.
Then the pair of wheels 5 along the rocker 34 and 35 and the pitched 32 and 33 of the relational roller is made with the possibility of rotation around the swing axis, which, in order to reduce the turning time, are surrounded by 25 the surfaces of two friction rollers are removed from the axis of symmetry of the wheel pair fixation device over a greater distance than the circumferential surfaces of the other two.

he rolls himself off the wheel set. After that, the machine for turning wheel pairs 1 is ready dp to re-profile the tire on the profile of another wheel pair,

Invention Formula
Machine for turning wheel pairs without rolling out to reprocess the tire on the wheel set of railway rolling stock, containing two noBOpoTHbfx calipers, a symmetric device for fixing the wheel pair, two pairs of drive friction rollers, each of which is designed to interact with one circumferential surface of the tire
The rotational roller is rotatable around the swing axis, characterized in that, in order to reduce the turning time, the circumferential surfaces of the two friction rollers are spaced more apart from the axis of symmetry of the wheel pair locking device than the circumferential surfaces of the other two.
