机械传动中,密封是必不可少的机构。尤其是动密封,是密封中的难题。要维持机构转动,传递力矩,就需留有合理的间隙;而对密封要求来说,又不能有间隙,所以正确处理这一矛盾,对保持设备性能,提高轴承寿命有着重要的实际意义。下面通过我厂改进前后两种密封形式的对比,来说明其新结构的优越性。 1.改进前的密封结构 图1为原来设计的密封结构。这是一种采用传统的毛毡槽加油毛毡进行轴端动密封,以使左端机体内
Mechanical transmission, the seal is an essential body. In particular, the dynamic seal is a problem in the seal. To maintain the body rotation, transmission torque, you need to leave a reasonable gap; and the sealing requirements, but also can not have gaps, so the correct handling of this contradiction, to maintain equipment performance and improve bearing life has important practical significance. The following through the improvement of our plant before and after the two forms of seal comparison, to illustrate the superiority of its new structure. 1. Before improving the seal structure Figure 1 is the original design of the seal structure. This is a use of the traditional blanket felt fills the shaft end seal, so that the left end of the body
