Function of bushing
Bushing has high flexibility and can play many roles. Generally speaking, bushing is a kind of component to protect equipment. The use of bushing can reduce the wear, vibration and noise of equipment, and has anti-corrosion effect. The use of bushing can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of equipment.
The function of bushing in practical work is closely related to its application environment and purpose. In the field of valve application, the bushing is installed in the valve cover to cover the valve stem, so as to reduce the leakage of the valve and achieve the sealing effect. In the field of bearing application, the use of bushing can reduce the wear between bearing and shaft seat and avoid the increase of clearance between shaft and hole. [2]
Material of bushing
The materials of bushings are mostly soft metal, rubber, nylon and non-metallic polymers. These materials have relatively soft texture and low price and cost. In various harsh working environments, the bushing bears vibration, friction and corrosion to protect the wrapped parts, and the bushing itself has the advantages of convenient replacement, low cost and good economy after damage.
Bushing selection factors
Bushing has a wide range of applications and many types. To select a suitable bushing, we must consider its purpose and select different types of bushings under different working conditions. The main conditions to be considered in the bushing selection are the pressure, speed, pressure speed product and load properties to be borne by the bushing. In addition, whether the bushing is lubricated and the state of lubrication also determines its service effect and service life.
