动力结构油封是现代机械设备和运输工具的一种理想的高效率油封,与普通油封比较,不但能胜任高速旋转密封,而且密封效果好,还可提高工作寿命若干倍,此种油封在发达国家应用比较广泛。为加速动力结构油封在我国推广应用。本文将常见的国外动力结构油封的主要设计参数以及它的基本特性概要地作一粗浅析述,供油封设计和应用者参考。一.动力结构油封的密封原理与特性动力结构油封好似一个微型泵,它的工作原理如图1所示,在螺纹轴的作用下,利用螺旋斜面,把具有一定粘度的油推向油侧。动力结构油封运用了这个
Power structure oil seal is a modern machinery and equipment and transportation of an ideal high efficiency oil seal, compared with the ordinary oil seal, not only capable of high-speed rotary seal, and sealing effect, but also improve the working life of several times, such oil seal in developed countries Wide range of applications. To accelerate the dynamic structure of oil seal in our country to promote the application. This article will be a common foreign dynamic structure of the main oil seal design parameters and its basic characteristics of a brief summary of the oil seal design and application of reference. First, the dynamic structure of the oil seal sealing principle and characteristics of the dynamic structure of the oil seal resembles a micro-pump, its working principle shown in Figure 1, the role of the threaded shaft, the use of spiral bevel, the viscosity of a certain oil to the oil side. Power structure oil seal used this
