圆柱销用途十分广泛。有些用于装配件的定位或定心或用于增强联接件的联接。有些则用于传递扭矩和动力。而另一些在铰接和销轴联接中则起到支承件的作用。在应用中,销子除了比联接件强度高外,还主要起到定位或定心的作用。销的尺寸按经验公式很容易确定,但是,如果销用来传递大的扭矩或动力,或销的强度比被联接件弱时,就需要进行各种强度验算。经验公式:如销承受剪切力,销的直径 Cylindrical pin uses a very wide range. Some are for positioning or centering of the fitting or for enhancing the coupling of the coupling. Some are used to transmit torque and power. While others act as supports in the articulation and pinning. In the application, the pin in addition to the high strength than the coupling, but also play a major role in positioning or centering. The size of the pin is easily determined by empirical formulas, however, various tests of strength are required if the pin is used to transmit large torque or power or if the pin strength is weaker than that of the coupling. Experience formula: If the pin withstands the shear force, the diameter of the pin
