Description
(54) СПОСОБ ИЗГОТОВЛЕНИЯ РОТОРА ВИНТОВОГО (54) METHOD OF MANUFACTURING A SCREW ROTOR
1one
Изобретение относитс к компрессоростроению , а именно к винтовым компрессора .м.This invention relates to a compressor industry, namely to a screw compressor.
Известен способ изготовлени ротора винтового компрессора путем обработки цилиндрической заготовки, например, дисковой фрезой 1.A known method of manufacturing a rotor of a screw compressor by machining a cylindrical billet, for example, a disk cutter 1.
Однако при изготовлении ротора указанным способом не учитываютс температурные расширени ротора, возникающие при его работе, что приводит к несовпадению рабочих и технологических зазоров в компрессоре .However, in the manufacture of the rotor in this way, the temperature expansions of the rotor arising from its operation are not taken into account, which leads to a mismatch of workers and technological gaps in the compressor.
Цель изобретени - повышение точности обработки.The purpose of the invention is to improve the accuracy of processing.
Указанна цель достигаетс тем, что согласно способу изготовлени ротора винтового компрессора путем обработки цилиндрической заготовки, заготовку предварительно нагревают до рабочей температуры ротора в компрессоре и поддерживают ее при обработке заготовки, а нагрев за .готовки осуществл ют или в масл ной ванне путем прокачки через нее вдоль заготовки, гор чего масла, или в масл ной ванне Электрическим током с одновременной .подачей охлаждающего масла вдоль заготовки, а КОМПРЕССОРАThis goal is achieved in that according to the method of manufacturing the rotor of a screw compressor by machining a cylindrical billet, the billet is preheated to the operating temperature of the rotor in the compressor and maintained during the processing of the billet, and the heating of the billet is carried out either hot oil, or in an oil bath by an electric current with simultaneous supply of cooling oil along the workpiece, and the COMPRESSOR
при выполнении заготовки полой ее нагрев осуществл ют прокачкой гор чей жидкости через полость заготовки.when a hollow blank is made, it is heated by pumping hot liquid through the blank cavity.
На фиг. 1 изображено устройство дл нагрева заготовки гор чим маслом; на фиг. 2 -- то же, дл нагрева заготовки электрическим током; на фиг .3 - то же, дл нагрева полой заготовки.FIG. 1 shows a device for heating a billet with hot oil; in fig. 2 is the same for heating the workpiece with electric current; Fig. 3 is the same for heating the hollow billet.
Устройство дл нагрева заготовки содержит масл ную ванну 1, захваты 2 дл креплени заготовки 3 с полостью 4 и обрабатывающий инструмент 5.The device for heating the workpiece comprises an oil bath 1, grips 2 for securing the workpiece 3 with a cavity 4 and a machining tool 5.
Ротор по предлагаемому способу изготавливаетс следующим образом.The rotor of the proposed method is manufactured as follows.
Заготовку 3 закрепл ют в захватах 2, предварительно нагрева до рабочей темis пературы ротора в компрессоре, и паддерживают ее при обработке заготовки 3 обрабатывающим инструментом 5.The workpiece 3 is fixed in the grippers 2, preheated to the working temperature of the rotor in the compressor, and held while processing the workpiece 3 with a processing tool 5.
Нагрев заготовки 3 осуществл ют в масл ной ванне 1 путем прокачки через нее вдоль заготовки 3 гор чего масла. Кроме ° этого, нагрев заготовки 3 можно осуществл ть в масл нной ванне 1 электрическим током, подведенным к захватам 2, с одновременной подачей охлаждающего масла вдоль заготовки. При выполнении заготовкиThe preform 3 is heated in the oil bath 1 by pumping hot oil through it along the preform 3. In addition, the heating of the workpiece 3 can be carried out in the oil bath 1 by an electric current supplied to the grippers 2, with simultaneous supply of cooling oil along the workpiece. When performing the workpiece
