FIELD: process engineering.SUBSTANCE: this process relates to reshaping of railway vehicle mounted axles running in bearings. This is made at mounted axle turning machines without rolling out from under rolling stock. Said machines incorporate cutting tools, machine system for control over machining tools, drive rollers, axial guide rollers, measuring rollers and mounted axle bearing housing grippers. To decrease amount of removed material at turning, mounted axle with the help of drive rollers is lifted above the track and cocked up, axle bearing housings are locked between drive rollers and clamps. Axial guide roller is fed to inner side of every wheel of said mounted axle and locked at this position. Drive rollers are loaded with extra force. Measuring roller is used to define the actual diameter and wear profile of every wheel. Proceeding from measurement data measured is the smallest actual diameter and, with preset machining allowance, is loaded as preset diameter to machine control system for machining tools.EFFECT: decreased removed ply of material.11 cl, 5 dwg |
