METHOD FOR MAKING OR REPAIRING RAILWAY ROAD WHEEL PAIRS Russian patent published in 2001 - IPC

FIELD: manufacture or restoration of wheel pairs of transport vehicles moving along rail tracks. SUBSTANCE: method comprises steps of measuring geometry parameters of wheel pair, performing magnetic and ultrasonic flaw detection of wheel pair in main line; simultaneously realizing the same operations with additional wheel pair in additional line; transferring all wheel pairs with regular wheels for turning circle of rolling and wheel pairs with defective wheels - to demounting position; in shop feeding new axles instead of defective ones; accumulating new and regular axles by several streams arranged one over another with use of gravitation force for their motion; then supplying to shop wheels preliminarily pressed onto axle and after final pressing of wheels onto axles forming wheel pairs; after passing wheel pairs through positions for turning circle of rolling, accumulating wheel pairs in accumulators placed in parallel in main and by-pass lines. Wheel pairs with regular wheels are transferred along by-pass line for turning circle of rolling through several zones of transportation in motion track. Buffer zones for placing several wheel pairs are used for transferring wheel pairs. EFFECT: enhanced efficiency of process for making or repairing wheel pairs. 8 dwg
