IE S050TRKP GEARBOX No. 0935 TEST REPORT
TRKP wagon gearbox: teeth back to nominal, bearing play reduced
Wheel teeth built up metal to the drawing nominal, radial clearances in the bearings decreased. 6.7–15.4 % — gear wheel tooth thickness at constant chord on the worn points, 3.5–3.9 → 4.04–4.16 mm (2001).

Key result
| GEARBOX COMPONENT | CONDITION BEFORE TREATMENT | WHAT WAS MEASURED |
|---|---|---|
| Gear wheel dwg. 81.26.153 | Tooth thickness 3.5–4.0 mm — worn below the drawing tolerance field | Tooth thickness at constant chord, five points |
| Pinion shaft dwg. 81.26.159 | Ran in mesh with the worn gear wheel | Tooth thickness at constant chord, seven points |
| Gearbox ball bearings | Play recorded | Radial clearance, commission inspection |
Gear wheel dwg. 81.26.153 — tooth thickness at constant chord
| MEASUREMENT POINT | BEFORE TREATMENT, mm | AFTER TREATMENT, mm | GAIN |
|---|---|---|---|
| Point 1 | 3.8 | 4.16 | +0.36 mm · +9.5 % |
| Point 2 | 4.0 | 4.06 | +0.06 mm · +1.5 % |
| Point 3 | 3.5 | 4.04 | +0.54 mm · +15.4 % |
| Point 4 | 3.86 | 4.14 | +0.28 mm · +7.3 % |
| Point 5 | 3.9 | 4.16 | +0.26 mm · +6.7 % |
Drawing nominal — 4.16 mm. Tooth thickness of the pinion shaft dwg. 81.26.159 after treatment — 3.98–4.16 mm at the same nominal.
Gearbox ball bearings — commission assessment
| COMPONENT | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Ball bearings of TRKP gearbox No. 0935 | Play recorded | Play reduced considerably against the initial measurements |
Wording of the commission following its inspection; the conclusion of the report records a reduction of the radial clearances in the ball bearings of this gearbox.
