The invention relates to a universal rotary joint for aviation refueling equipment. The universal rotary joint comprises a universal rotary joint body, and a first workpiece and a second workpiece that are connected with two ends of the universal rotary joint body, wherein the first workpiece and the second workpiece are both formed by fixedly connecting workpiece bodies with connecting plates, two fastening screws and flat spring washers are arranged outside the universal rotary joint body, an outer lining and an inner lining which are through are arranged inside and outside the part, between the first workpiece and the second workpiece, of the universal rotary joint body, the outer lining and the inner lining are connected through balls and pin rollers and limit axial movement of the outer lining and the inner lining, and four sealing layers are arranged between the outer lining and the inner lining for sealing the outer lining and the inner lining. The universal rotary joint has the advantages that the first workpiece and the second workpiece can rotate at a relative angle through the universal rotary joint body, flowing and loss of fluid in the middle are not affected, corrosion resistance, permeation resistance, high efficiency and high stability are achieved, and the workpieces can effectively rotate by 360 degrees.
本发明涉及一种航空加油设备用万向旋转关节,包括万向旋转关节及其两端连接的第一工件与第二工件,第一工件与第二工件均由其工件与连接板固定连接组成,万向旋转关节外部设有两个紧固螺丝和平弹垫;第一工件与第二工件之间的万向旋转关节内外设有贯穿的外衬套及内衬套,外衬套与内衬套之间通过滚珠、滚柱进行连接及限制外衬套与内衬套的轴向移动;外衬套与内衬套之间设有四道密封层进行两者的密封。本发明的优点是,实现第一工件与第二工件通过万向旋转关节进行相对角度的旋转,且不影响中间内部流体的流动及流失,耐腐蚀、耐渗透、高效率、高稳定性,且工件能有效进行360°旋转。
