油封弹簧规格的选择及适用性分析

Specification Selection and Applicability Analysis of Oil Seal Spring

介绍油封弹簧径向力(P)的一种计算方法,并进行试验验证。选取8种常用规格(0.30×1.6,0.36×2.0,0.45×2.5,0.50×3.0,0.60×3.5,0.80×4.0,1.00×5.0和1.20×7.0)的油封弹簧,在不同轴径(50~1600 mm)和不同伸长率(<10%)下分别计算P;依据P的推荐取值,得出适合规格油封弹簧轴径的适用范围,为油封弹簧的选型和设计提供参考。

A calculation method of the radial force of oil seal spring(P)was introduced,and the verification test was carried out.8 kinds of common oil seal springs(0.30×1.6,0.36×2.0,0.45×2.5,0.50×3.0,0.60×3.5,0.80×4.0,1.00×5.0 and 1.20×7.0)were selected,and P values were calculated under different shaft diameters(50~1600 mm)and different elongation(<10%).According to the recommended P values,the applicable ranges of the shaft diameter of suitable specifications of oil seal spring were obtained,and a reference for the selection and design of the oil seal spring was provided.
