大型减速器在重型、矿山、起重运输等机械的传动系统中有重要地位,而减速器的寿命主要取决于其齿轮对的好坏。近几年来,我国大型减速器产量和质量有很大的提高,基本上满足了需求。但在使用寿命上,与国外先进水平相比,还有一定差距。提高齿轮的承载能力和使用寿命,仍然是机械工业中的一项重要任务。 Large reducer in heavy duty, mining, lifting and other mechanical transmission system has an important position, and reducer life depends mainly on the quality of its gear pair. In recent years, China’s large reducer output and quality have greatly improved, basically to meet the demand. However, in the service life, compared with the advanced level abroad, there is still a certain gap. Increasing the carrying capacity and service life of gears remains an important task in the machinery industry.
