Bushing is a matching part used outside of mechanical parts to achieve sealing, wear protection, etc. It refers to a ring sleeve that acts as a gasket. In the field of valve applications, it is generally used in the valve cover, using corrosion-resistant materials such as polytetrafluoroethylene or graphite for sealing. So how much other knowledge do you know about it? Let’s take a look at the editor of Cheapest Self-lubricating sleeve!
1. Installation: Bushing has been lubricated before leaving the factory and can be installed and used directly. When installing, it is necessary to first screw three bolts into the screw holes of the flange of the other part and distribute them evenly along the circumference to open the inner sleeve and outer sleeve. Then put the expansion sleeve into the hub hole at the designed position, and use the force measuring wrench to tighten the bolts. The method of tightening is that each bolt is only tightened to 1/4 of the rated torque at a time. The tightening sequence is bounded by the slit. Tighten the screws in a symmetrical direction to ensure that the rated torque is reached.
2. Disassembly: Loosen all bolts a few turns before disassembling. Then screw the bolt top loose expansion sleeves crosswise into the disassembled screw holes.
3. Protection: Prevent the expansion sleeve from being polluted during installation. On machines operating in the open air or in a poor working environment, anti-rust grease should be regularly applied to the exposed end faces and bolts of the expansion sleeve, and the expansion sleeve type with better rust resistance should be selected. Expansion coupling sleeve is a modern new advanced mechanical basic part. It is a new type of non-key coupling device widely used in the world to realize the connection of mechanical parts and shafts. It is a new type of non-key coupling device that realizes load transmission by tightening the pressure and friction force between the containing surface by tightening the 12.9 grade high-strength screws.
In summary, the editor of Cheapest Self-lubricating sleeve tells: a brief introduction to the relevant knowledge of Bushing, I hope you can learn more through the introduction of the above editor.
