铜铅合金轴承制造的一些问题铜铅合金是一种比较新的轴承合金,主要应用在高速柴油发动机等方面,因为这些发动机的轴承,单位面积压力很大(一般在每平方公分2O公斤以上),磨擦速度也很高(每分钟在600公尺以上),而白合金(俗称硬铅)因为耐疲性和高温强度太差(一般的锡基白合金在室温时,硬度有布氏22－26,但到10℃时,就只有布氏7—10),不能在这种情况下使用。所以随着目前工业上的需要,铜铅合金轴承的应用也就跟着拓展了。到目前,许多高压力的轴承如铁路机车轴承和某些轧钢机、工具机的轴承,也都在开始采用了。
Copper-lead alloy bearing some of the problems Copper-lead alloy is a relatively new bearing alloy, mainly used in high-speed diesel engines, etc., because these engine bearings, the unit area pressure (typically more than 2O kg per square centimeter) , Friction speed is also high (600 meters per minute or more), and white metal (commonly known as hard lead) because of fatigue resistance and high temperature strength is too poor (general tin-based white metal at room temperature, the hardness of 22- 26, but to 10 ℃, only Brinell 7-10), can not be used in this case. So with the current industrial needs, the application of copper-lead alloy bearings also will be expanded. So far, many high-pressure bearings such as railway locomotive bearings and some rolling mills, machine tool bearings, are also beginning to be used.
