一、汽缸壁滚辗储油沟槽改善汽缸配合副的润滑条件,一般都着重在改进和完善发动机的结构,忽视了缸壁本身储油能力的重要作用。显然,即使在现有发动机结构不变的条件下,如能改进缸壁储存润滑油的能力,也将能收到同样的效果。增加缸壁储油能力,可有两种途径,一是改变汽缸材料结构,使其形成具有一定储油能力的微细空穴;另一是通过机械加工,在已珩磨好的缸壁上造成储油沟槽或网眼。我们采用机械加工法,用振动钢珠滚辗缸 First, the cylinder wall rolling oil storage groove to improve the lubrication conditions of the cylinder mating pair, generally focus on improving and improving the structure of the engine, ignoring the cylinder wall itself, the important role of oil storage capacity. Obviously, even if the existing engine structure remains unchanged, the same effect can be obtained if the ability of the cylinder wall to store lubricating oil can be improved. There are two ways to increase the cylinder wall oil storage capacity. One is to change the material structure of the cylinder so that it forms a small cavity with a certain oil storage capacity; the other is to create a reservoir on the already well-ground cylinder wall by machining. Oil groove or mesh. We use mechanical processing method, using vibrating steel ball rolling cylinder
