What is a Mechanical Bushing?

Bushing is a matching piece used outside the 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, the bushing is inside the valve cover, and generally anti-corrosive materials such as polytetrafluoroethylene or graphite are used for sealing.

1. The taper angle difference of the adapter sleeve must be good. The national standard is expressed by D1mp- d3mp. The tolerance of different size segments is from + 0.0180.09. Must cooperate with contact, small end of cone can be a little

Applications: Packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, various machine tools and interchangeable mechanical transmission linkages. For example: belt pulleys, sprocket wheels, gears, propellers, large fans, and various other connections; characteristics: large torque, high accuracy, easy assembly and disassembly, simple operation, good positioning, reducing the scrap rate of the mated shaft and hub, Reusable without damaging the mating surface, it is the most ideal and economical choice at present.

1. Installation: The bushing has been lubricated at the factory and can be directly installed and used. When installing, first screw three bolts into the screw holes of the flanges of the other parts and distribute them along the circumference to open the inner sleeve and outer jacket. Then put the expansion sleeve into the hub hole in the design position, and use a force-measuring wrench to tighten the bolts. The tightening method is that each bolt is only tightened to 1/4 of the rated torque at a time. The left and right crosses are tightened one after another to ensure that the rated torque is reached.

2. Disassembly: When disassembling, loosen all bolts a few times. Then screw in the top of the bolt loosening sleeve in the disassembled screw hole.

3. Protection: Prevent expansion sleeve pollution during installation. On open-air operations or machines with poor working environments, the exposed end faces of the expansion sleeves and bolts should be regularly coated with anti-rust grease, and an expansion sleeve type with better rust resistance should be selected. Expansion tight coupling sleeve is a modern new type of advanced mechanical foundation piece. It is a new type of keyless coupling device that is widely used in today's world to realize the connection between mechanical parts and shafts, and to realize the load transfer by tightening the pressure and friction generated between the containment surfaces by tightening 12.9 high-strength screws. ^[3]
