Description
Затем трубу-заготовку сво-бодно насаживают на вал с учетом технологического припуска (по 50-100 мм с каждого торца вала) производ т автоматическую наплавку на трубу-заготовку сло высоколегированной нержавеющей Стали не менее, чем за два прохода сварочного автомата.Then, the billet pipe is loosely mounted on the shaft, taking into account the technological allowance (50-100 mm from each shaft end), automatic welding on the pipe-billet of a high-alloyed stainless steel layer is made in no less than two passes of the welding machine.
При этом в трубе-заготовке возникают сварочные напр жени сжати , достаточные дл создани необходимого .нат га в соединении облицовки с валом. Технологический припуск по длине заготовки необходим вследствие деформации концов трубы-заготовки при наплавке, вызывающей отставание от вала . В завершение выполн ют механическую обработку облицовйи - обточку на станке до заданного наружного диаметра и обрезку технологических припускав по торцам. Предлагаемый способ обеспечивает соединение облицовки с судовым валом без переналр жени тела вала, устран ет сложные технологические операции гор чей насадки и сварки стыков частей труб-заготовок, чем существенно повышаетс надежность облицовки, исключает необходимость в сложном оборудовании и снижает трудоемкость монтажа облицовки на судовом валу.In this case, compression stresses occur in the blank pipe, which are sufficient to create the required voltage in the joint between the lining and the shaft. Technological allowance along the length of the workpiece is necessary due to the deformation of the ends of the pipe-billet during surfacing, causing a lag from the shaft. In conclusion, they perform the mechanical treatment of the facing - turning on the machine to the specified outer diameter and cutting the technological pripuskav on the ends. The proposed method allows the liner to be connected to the ship shaft without rewiring the shaft body, eliminates the complicated technological operations of the hot nozzle and welding the joints of the parts of the pipe billets, which significantly improves the reliability of the liner, eliminates the need for complex equipment and reduces the laboriousness of installing the liner on the ship shaft.
