Key result
| EQUIPMENT | SERVICE RUN AFTER TREATMENT | WHAT WAS MEASURED |
|---|---|---|
| Passenger car No. 13585, reduction gear with bevel gear drive | 10,000 km in the ‘Baku — St. Petersburg’ train | Thickness of two diametrically opposite gear wheel teeth at a height of 2.82 mm from the tip — at the outer, mid and inner diameter of the rim |
Bevel gear wheel tooth thickness — three points across the rim width
| MEASUREMENT POINT | BEFORE, mm | AFTER 10,000 KM, mm | CHANGE, mm |
