Bushing
Introduction
Bushings are suitable for rotating, oscillating and linear movements, whereas straight (cylindrical) bushings can accommodate radial loads only and flanged bushings can accommodate radial and axial loads in one direction.
Each combination of bushing design and material has characteristic properties and makes a bushing particularly suitable for certain applications.
The bushing is used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.
Structural Features
Large torque, high accuracy, convenient and quick assembly and disassembly, simple operation, good positioning, reduce the scrap rate of matched shafts and hubs, reusable, and do not damage the mating surface. It is currently the most ideal and economical choice.
Features and Benefits
● Low friction resistance: The steel ball can perform stable linear motion with very small friction resistance due to the correct orientation of the retainer.
● Stainless steel: stainless steel series are also available, suitable for applications requiring corrosion resistance.
● Exquisite design: The size is extremely small and can be designed in exquisite mechanical equipment.
● Rich variations: In addition to the standard type, there are also a series of high-rigidity long types, which can be selected according to the purpose.
Function
●The flexibility of the bushing is relatively high, and it can play many functions. In general, the bushing is a kind of component that protects the equipment. The use of bushings can reduce equipment wear, vibration and noise, and has an anti-corrosion effect. The use of the bushing can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of the equipment.
●The role of the bushing in actual work has a lot to do with its application environment and purpose. In the field of valve applications, the bushing is installed in the valve cover to cover the valve stem to reduce valve leakage and achieve a sealing effect. In the bearing application field, the use of bushings can reduce the wear between the bearing and the shaft seat and avoid the effect of increasing the gap between the shaft and the hole.
Application
Application: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, various types of machine tools and interchangeable machinery transmission connection. For example: pulleys, sprockets, gears, propellers, large fans and various other connections.
