国内对于“热轧齿输”这门具有高生产率的齿输生产技术,几年来由于党的关怀和各方面不懈的试验研究,已取得了不少成绩。我厂郑富有同志所创造的用煤炭炉加热轧坯的“土热轧齿输法”,经几年来的摸索,可以肯定在一定条件和要求下是能用于正式生产的。我厂以此法大量生产各型汽车曲轴正时齿输,产品质量(精度和机械性能)稳定,符合技术要求。这种方法的特点,主要是依靠将其中某几道工序倒置,以及采取某些技术措施来保证产品的精度。现将我厂所获初步经验简介于后。生产方式:轧坯用反射炉加热,在卧式轧齿机上以双辊轴向(水平)送进轧制,依次用石墨粉、薄机油润滑。
The domestic production technology of “high-productivity tooth transmission” has been achieved domestically for years. Thanks to the care of the party and unrelenting experimental studies in various fields, many successes have been achieved. After years of exploration, it is certain that under the condition of certain requirements and requirements, the “hot-rolled tooth method” created by our company, Comrade Zheng Fuyou, can use it for formal production. I plant in mass production of various types of automotive crankshaft timing teeth lose, product quality (accuracy and mechanical properties) stability, in line with technical requirements. The characteristics of this method depend mainly on the inversion of certain processes among them and the adoption of certain technical measures to ensure the accuracy of the product. Now I plant the initial experience gained after the brief. Production methods: Billet heated with a reverberatory furnace, in the horizontal roller gear to the double-roll axial (horizontal) into the rolling, followed by graphite powder, thin oil lubrication.
