Removing fluid coupling new methods and special tools

Mining machinery plexus less mechanized mining face in the work for many years, two mechanized mining work t two scraper conveyor with hydraulic coupling on the reducer shaft some benefits over a half key connection, with more closely, it is difficult demolition the coupling shell material is aluminum alloy, can not be a greater impact force J a configurable split hydraulic coupling bolts fine thread will thread damage during disassembly, it is difficult to remove the fluid coupling, sometimes need to take a long time to smash the fluid coupling can remove the sleeve, so that it can not be seized  Hydraulic pipe fittings  coupling repair Sichuan, bring children to use the unit thousand economic losses, but also seriously affect the production the author, after much thought, came up with a method of removing fluid coupling Sichuan tools and expertise, through use to good effect. Hydraulic coupling disassembly works shown in Figure l, the demolition of the shaft with the special tool shown in Figure 2 closely. Reducer I use hydraulic coupling shaft surface and the center of the inner sleeve larvae L} pressed into an empty month empty the working principle of the use of tanks, can I axis as piston rods, hydraulic coupling sleeve as removing fluid coupling and reducer bushing center
