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, Russia warehouse High quality Nema 34 Stepper Motor 12v dc motor 8.5N.m for CNC coupling, universal Joint Assembly) life;
5.Reduce the user’s discomfort;
6.Reduce the power consumption of the product;

Screw Shaft TypesIf you’re looking for a screw shaft, but aren’t sure which type to buy, you’re in luck. In this article, we’ll talk about the different types, including Threaded shank, Round head, and Machined. Once you’ve read it, you’ll know which type to buy. Then, you can decide whether you want a ball screw nut or a threaded shank. Machined screw shaftsBesides the standard stainless steel shaft, manufacturers also provide a variety of other materials, such as titanium, bronze, and brass. In addition to stainless steel, manufacturers also provide a variety of top-coating options, including zinc, brass, and chromium. Aluminum screws are not particularly durable and are easily affected by weather. Most screw shafts feature self-locking mechanisms. They are especially useful in C-clamps, vises, and screw-top container lids. Ball screw nutsIf you have a screw shaft, the last thing you want to worry about is the ball nut slipping off. To prevent this, you can place a temporary stop in the shaft’s grooves to ensure that the ball nut does not slide off. When you remove the stop, you can then install the ball screw nut. But, before you can install the ball screw nut, you have to make sure that you have a good grip on the shaft. Threaded shankWood screws are usually not fully threaded because the shank has an unthreaded portion at the top. This shoulder part forces the screw to compress two pieces of wood, which prevents the screw from overheating and compromising the materials strength. As the screw is threaded partially up, it is not as difficult to remove as a fully threaded screw. However, it is important to note that a wood screw will not hold as tightly as one with a fully threaded shank. Round headA round head screw is the most common type used for machine screws. Other common types include truss head, flat head, and hexed head. Each has a different profile and are used for different purposes. A round head screw is typically wider than a flat or a hexed head, and has a slightly rounded surface. These screws are useful for projects involving sheet metal or sheet-metal parts. Round heads are usually slightly wider than a hex head screw, and they may also be used as a substitute for washers in certain applications. However, truss heads are not necessary for every project. Self-locking mechanismA self-locking mechanism for a screw shaft is a device that secures the screw to its supporting member in a failure position. The locking mechanism provides a positive connection between the screw shaft and the control surface during normal operation, and locks the screw to its supporting member when the screw fails. Previous attempts to solve this problem have typically used secondary nuts with free play on the screw, which were intentionally designed to jam when loaded. However, such a device can be unreliable, which is why the present invention offers a more robust and reliable locking mechanism.
