Technology approval of locomotive wheel production

This paper presents the results of measurements of some particular dimensions aimed to confirm the adequacy of technology of making wheel Φ1250 mm of electric locomotive type HŽ 1141 and HŽ 1142. The row material is one piece, made as monoblock. We analyzed technology requirements (request circularity, tolerance of holes) and accuracy of making after heat treatment and hard turning. For this analysis we used the Student distribution test. The wheel was made of carbon steel (chilled steel) and material before turning must be annealed.
