Introduction of drive shaft
1. Drive shaft is the part for connecting and assembling various accessories, and turning cylindrical object parts.
2. The drive shaft is composed of a shaft tube, rubber sheath, seal and a universal joint .
3.The screw pump drive shaft is the drive power transmission to the coupling rod, thus driving the rotor rotation. Several components are connected by a universal joint or a flexible shaft.
4.The drive shaft material has 304, 316L, 40Cr, 2Cr13, 2205, 904L, also needs to make the adjustment qualityor surface treatment of hard chromium .
The material of drive shaft we commonly used:
SUS304 ; 304, 316L, 40Cr, 2Cr13, 2205, 904L
Screw pump drive shaft common sense:
1.The overall layout of the screw pump determines the dimensions of the drive shaft and their range of change. If the drive shaft is damaged, worn, deformed, and loses its dynamic balance, will cause abnormal sound and vibration in the running screw pump,When serious, it can cause the related parts to be damaged,So the rationality of the drive shaft design will directly affect lifetime of universal joint assembly and drive shaft, and efficiency of universal drive and stability of screw pump operation
2.To usedrive shafts along with different drive products, the surrounding work environment is more complex, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive medium, saline, radiation and other conditions, these are important factors to be considered when selecting the drive shaft
3. The drive shaft is a rotating body with a high rotational speed and less support, it is dynamic balance is very important.In general, the drive shaft before the factory to carry out a dynamic balancing test, need to adjust on the balance machine.
There are 6 major functions of the drive shaft
1. Improve the rotor and its composition of product quality;
2. Reduce noise;
3. Reduce vibration;
4. Improve the support components (such as the joint shaft, coupling, universal Joint Assembly) life;
5.Reduce the user’s discomfort;
6.Reduce the power consumption of the product;
