目前小四轮拖拉机和手扶拖拉机的发动机大多是195型柴油机,其型号主要有 S195、X195、山东195与 L195型等。为使用户对上述机器的轴瓦性能有所了解,以便正确装配、选用,提高轴瓦的使用寿命,特作如下简介。一、轴瓦的材料及质量要求195型柴油机轴瓦采用20%高锡铝合金—钢双金属条制造,制造时根据主轴瓦及连杆瓦的规格,选择不同厚度,长度、宽度的金属条。双金属条的底板为08号钢,工作层为20%高锡铝合金经轧制复合组成。
At present, the engines of small four-wheel tractors and walking tractors are mostly 195 type diesel engines. The models mainly include S195, X195, Shandong 195 and L195. To enable users to understand the performance of the bearing bush, in order to correctly assembly, selection, to improve the service life of bearing, especially for the following introduction. First, the bearing material and quality requirements 195-type diesel engine bearing with 20% high-tin alloy - steel bimetal strip manufacturing, according to the main bearing and connecting rod tile specifications, choose different thickness, length, width of the metal strip. The bottom of the bimetal bar is 08 steel, the working layer is 20% high tin aluminum alloy by rolling composite composition.
