摩擦力與O型圈的應(yīng)用在動密封裝置中，摩擦與磨損是O型圈損壞的重要影響因素。磨損程度主要取決于摩擦力的大小。當(dāng)液體壓力微小時，O型圈摩擦力的大小取決于它的預(yù)壓縮量。當(dāng)工作液體承受壓力時，摩擦力隨之工作壓力的增加而增大。在工作壓力小于20MPa的情況下，近似地呈線形關(guān)系。壓力大于20MPa時，隨著壓力的增加，O型圈與金屬表面接觸面積的增加也逐漸緩慢，摩擦力的增加也相應(yīng)緩慢。在正常情況下，O型圈的使用壽命隨著液體壓力的升高將會近似的呈平方關(guān)系而減小。摩擦力的增加，使得旋轉(zhuǎn)或往復(fù)運動的軸與O形密封圈之間產(chǎn)生大量的摩擦熱。由于多數(shù)O型圈都是用橡膠制成的，導(dǎo)熱性極差。因此，摩擦熱就會引起橡膠的老化，導(dǎo)致O型圈實效，破壞其密封性能。摩擦還會引起O型圈表面損傷，使壓縮量減小。嚴(yán)重的摩擦?xí)芸煲餙型圈的表面損壞，失去密封性。作氣動往復(fù)運動用密封時，摩擦熱還會引起粘著，造成摩擦力進(jìn)一步增加。運動用密封在低速運動時，摩擦阻力還是引起爬行的一個因素，影響元件和系統(tǒng)的工作性能。所以對運動密封來說，摩擦性是重要性能之一。摩擦系數(shù)是摩擦特性的一個評價指標(biāo)，合成橡膠摩擦系數(shù)較大，由于密封在運動狀態(tài)時。
