橡胶件的漏油问题是一个比较普遍而又复杂的技术问题,影响向因素很多。一般认为除了橡胶材料质量原因外,主要有三个因素影响其封严效果及使用寿命:1.封严部位的表面状况(光洁度、偏心度、切削沟纹等):2.装配质量;3.橡胶件的工作尺寸变化。这种变化与橡胶和工作油介质的匹配情况有着密切的关系。试验证明,橡胶件在油介质中的尺寸变化与其体积变化、重量变化是等效果的,即尺寸胀大则其重量增加,体积增大。因此,可从橡胶在油中的重量、体积变化预测出尺寸变化,
Oil spill problem is a more common and complex technical issues, the impact of a lot of factors. Generally believed that in addition to the rubber material quality reasons, there are three main factors that affect the sealing effect and service life: 1. Sealing parts of the surface conditions (finish, eccentricity, cutting grooves, etc.): 2. Assembly quality; 3. Rubber Work piece size changes. This change is closely related to the match between rubber and working oil media. Tests show that rubber parts in the oil medium size change and its volume change, weight change is the equivalent effect, that is, the size of the expansion of the weight increase, the volume increases. Therefore, the rubber in the oil from the weight and volume changes predicted changes in size,
