一、概况热轧齿轮是热滚轧工艺的一种,国外约在1860年就开始试验研究,但收效不大.直到1935年发明了高频感应加热方法之后,它才得到了实质性的发展.目前,苏联、日本、西德等国通过大量的试验研究后,已在某些齿轮厂用于实际生产.其轧制模数可达12,轧制直径范圈为30～1000mm,精度可达8～9级.它应用在生产中有三种形式:1)热轧后齿轮不再机械加工,可用于精度要求较低的零件,如电动凿岩机等:2)热轧后齿形进行冷精轧整形,精度达8级,可用于拖拉机上;3)热轧后齿形进行精密机械加工,可用于汽车、拖拉机上。
First, the overview Hot-rolled gear is a kind of hot rolling technology, the foreign about 1860 began experimental study, but with little success until 1935 invented high-frequency induction heating method, it has been a substantial development At present, the Soviet Union, Japan, West Germany and other countries through a large number of experimental studies, has been used in some gear factory for the actual production of its rolling modulus up to 12, the rolling diameter range of 30 ~ 1000mm, the accuracy of Up to 8 to 9. It is used in production in three forms: 1) after hot rolling gear is no longer machined, can be used for parts with lower precision requirements, such as electric rock drill, etc .: 2) Roll shaping, accuracy of 8, can be used on tractors; 3) After hot-rolled toothed shape for precision machining, can be used in cars, tractors.
