Screw pump Coupling Rod bush action
The function is to support the shaft, avoid grinding of direct drive shaft and coupling rod, Reduce the damage on the drive shaft and a shaft coupling device, play a protective effect, and make the shaft composite rotary motion in the bushing.
Bushing can not only reduce the wear, vibration and noise of equipment, and has the effect of corrosion prevention. It can also facilitate the maintenance of mechanical equipment, simplify the structure and manufacturing process of equipment
Screw pump Coupling Rod bush material
Commonly used materials are 45 steel, 40Cr alloy steel, medium carbon steel, bearing steel GCr15 and spring steel 65Mn, as well as 20CrMoTi, 20Mn2B, 20Cr, etc.
The material of Coupling Rod bush my company commonly used :
Design and application of screw pump Coupling Rod bush
Screw pump bushing is used for coupling rod ends, which is an important part of the universal joint assembly of connecting the rotor and the drive shaft
In these moving parts, due to the friction of the long-term caused by friction, parts need to be replaced when Parts need to be replaced when the axial gap and hole wear to a certain degree of time, Therefore, we must select the material with better wear resistance for the bushing, which can reduce the wear and tear between the shaft to shaft. We must choose a better wear resistance material for the bushing, which can reduce the wear between the shaft and the shaft. When the bushing is worn to a certain extent, it can be replaced, so that it can save the high cost caused by the replacement shaft. When the bushing is worn to a certain extent, it will be replaced, this can save the high cost of replacement shaft, In general, the installation of bushing and shaft is clearance fit, this installation method cannot avoid wear, can only choose to extend the life of parts, The bushing type parts are relatively easy to produce,, the cost is relatively low.
