2. The device according to claim 1, about tl and - the fact that the synchronization mechanism is complete in the form of a central synchronizing bevel gear, which is perpendicular to the axis of the yakatnik, and two bevel gears installed along the axis of the knurls with the possibility of interacting with the central sync wheel

The invention relates to the processing of metals by pressure and can be used in the manufacture of gears for machining the ends of the teeth.

The purpose of the invention is to improve the quality of processing by hardening the ends of the teeth of the wheel to be machined.

1 shows a device for processing the ends of the teeth of gear wheels; Fig. 2 is a diagram of the interaction of the nakatnik with the gear wheel being processed; in FIG. 3, view A in FIG. 2.

The device contains synchronizing bevel gear 1, knurling 2, rigidly connected with pins 3 and bolts 4 with synchronizing gear gears 5 mounted on axis 6 using bearings 7. Axle 6 is installed in floating rod 8. Clamp 9 is used to set the wheel to be machined 10 in a certain position relative to the synchronization gear 1 on the mandrel 11 with quick-change washer 12.

The device works as follows.

The machined wheel 10 is mounted on the mandrel 11 and fixed in position along the tooth in the required position: with a latch 9. A quick-change washer 12 is installed, the mandrel is fed down, for example, with a pneumatic cylinder, and the machined wheel 10 is clamped in the tool.

Bevel gears 5, on which the knuckles 2 are mounted, are engaged with the synchronizing gear43.

each one of the bevel gears is rigidly connected to the respective knurling gear.

3. A device according to claim 1, characterized in that radial recesses are made at the end of the teeth of the knurser to interact with the corresponding tooth end of the wheel to be machined.

Thorn I. Nakatnik self-aligning with the surface to be treated due to the presence of a gap in the gears of gears 1 and 5

and floating rod.

Through the rod 8 from the loading device, the tensioners are loaded with the required force and are rotated around the axis of the rod. After a predetermined number of revolutions, a reverse is performed to ensure uniform processing.

After reaching the required degree of hardening of the end surfaces of the teeth, the rotation of the rod 8 is stopped, the load is removed, the gears 5 are continuously disengaged from the gear 1, the mandrel 11 is fed up, the washer 12 is removed and the machined wheel 10 is removed from the device.

There is no engagement between the reamer and the gear to be machined. The working surface of the nakatnik during processing is with a shock, the load comes in contact with the tooth surface being treated with the entire surface at the same time and then comes out of contact with it. Next, the next face of the knurling wheel interacts with the front face of the next tooth. In this way, all gear teeth are sequentially processed.

In the device, the processed gear wheel 10 together with the synchronous bevel gear 1
