一、椭圆形轴瓦的概念椭圆形轴瓦也叫径向变厚度轴瓦(或称不等厚轴瓦)。该轴瓦的特点是径向厚度不一致,是一种新型结构的产品。目前,椭圆形轴瓦已应用到90系列、95系列、105系列等国产柴油机上。据有关资料介绍,4115T、4125A型柴油机,也开始试用椭圆形轴瓦了。 First, the concept of oval bush Oval bush also known as the radial variable thickness bush (or unequal thickness bush). The bearing is characterized by inconsistent radial thickness, is a new structure of the product. At present, oval bearings have been applied to 90 series, 95 series, 105 series and other domestic diesel engine. According to the relevant information, 4115T, 4125A diesel engine, also began trial oval bushings.
