人们可能知道“栽树”,是使树在土中生根,拔不出来。“栽丝”也是这样,螺栓“栽”入基体中,并在基体中“生根”。 国产的某些492系列汽油机的气缸体多采用ZL104铝合金以低压铸造成型。气缸体是发动机的基体,气缸体上部“栽”有缸盖螺栓。缸体上还装有飞轮离合器壳、主轴承盖、正时齿轮盖、机油盘和凸轮轴总成等零部件,这些联接件都采用螺栓联接,也多为“栽”植螺栓,因为“栽丝”是一种可靠的螺栓联接方法。
People may know that “planting trees” is to make the tree take root in the soil and can not pull it out. The same is true of “planting silk,” bolts “planted” into the matrix, and “rooted” in the matrix. Some domestic 492 series gasoline engine cylinder body more use ZL104 aluminum alloy to low pressure casting molding. The cylinder block is the base of the engine. The upper part of the cylinder block is “planted” with cylinder head bolts. Cylinder body is also equipped with flywheel clutch housing, the main bearing cover, timing gear cover, oil pan and camshaft assembly and other parts, these connections are used bolt connection, but also mostly “planted” plant bolts, because “planted Wire ”is a reliable method of bolting.
