WHEEL SETS REPAIR
Our company conducts intermediate and complete checkup of wheel tread with turning and without it, a complete checkup of wheel thread with overlaying welding and turning.
Wheel set consists of axle, all-rolled wheels, axial gear, labyrinth seals of bearings and cups whereon axial gear box is mounted. Diameter of wheel rolling circle is 1050 mm. Wheels and gears are fitted by thermal method. Wheel set axle is made of OSL steel, neck surfaces, wheel seat and section before wheel seat are burnished with rollers at 2500 kg load per roller, thereafter these surfaces are polished. Roller burnishing several times increases necks fatigue strength and reduces its wear at repressions of bearings. On one side of the axle there is a drilling whereto square hole sleeve is pressed under speedometer drive shank. The sleeve is made of steel and heat treated to hardness in order to avoid rapid wear of square hole.
