与平键联接比较，花键联接在强度、工艺和使用方面有下列特点：在轴上与毂孔上直接而均匀地制出较多的齿与槽，故联接受力较为均匀；因槽较浅，齿根处应力集中较小，轴与毂的强度削弱较少。

Compared with the flat bond connection， the spline connection has the following characteristics in strength，圣霖国际联接机选购， process and use.More teeth and grooves are made directly and evenly on the shaft and hub hole， so the joint force i*ore uniform.

Because of the shallow groove，圣霖国际联接机价格， the stress at the root of the tooth is *all，圣霖国际联接机， and the strength of the shaft and hub is weakened less.

花键联接由内花键和外花键组成。内、外花键均为多齿零件，在内圆柱表面上的花键为内花键，在外圆柱表面上的花键为外花键。显然，花键联接是平键联接在数目上的发展。

The connection of the splinde up of the inner and outer spline. The inner and outer spline are multi tooth parts， and the spline on the surface of the inner cylinder is the inner spline， and the spline on the outer cylindrical surface is the outer spline. It is that the spline connection is the developme*f the number of flat bond connecti*.

销联接一般用来传递不大的载荷或作安全装置；另一作用是起*作用。常与带孔螺栓和六角开槽螺母配对使用，把销插入螺栓的孔与螺母的槽中，以防螺母松脱。销按形状分为圆柱销、圆锥销和异形销三类。

Pin connecti* are generally used to transfer *all loads or safety devices; the other is to play the role of . It is often paired with hole bolts and six angle slotting nuts to insert the pin i* the hole of the bolt and the slot in the nut so as to prevent the loosening of the nut. The pin is divided i* three types: cylindrical pin， conical pin and special pin.
