Types of screw rods

There are some differences in the application of ball screws and trapezoidal screws. The application systems of original equipment manufacturers often require products that are "exactly right", and trapezoidal screws are often the right choice. The trapezoidal screw product is easy to adjust based on specific applications to achieve expected performance while keeping costs at a low level. In some cases, life testing may be required during the design phase, but for original equipment manufacturers, conducting such additional work in the early stages can help reduce product costs. The ball screw can operate continuously, withstand much higher loads, and achieve faster speeds, which is worth the additional cost. For end users of Zui, ball screws have good predictability, making them the best choice for ensuring fast integration and reliability. For example, factory automation systems heavily rely on ball screw technology. Of course, many original equipment manufacturers also require ball screws for their application systems, such as in the machine tool industry.

The multi head screw manufacturer tells you what are the characteristics of the screw

1. High axial stiffness

The ball screw pair can be pre pressed, as the pre pressure can cause the axial clearance to reach a negative value, thereby obtaining higher rigidity (by applying pressure to the ball in the ball screw, when used in mechanical devices, the repulsive force of the ball can enhance the rigidity of the threaded part).

2. Due to the rolling motion of many balls between the screw shaft and the screw nut of the ball screw pair, high motion efficiency can be achieved. Compared with the past sliding screw pair, the driving torque reaches less than 1/3, which means that the power required to achieve the same motion result is 1/3 of the power required to use the sliding screw pair. It is very helpful in saving electricity.

3. Cannot self lock and has reversible transmission

Precautions for safety and adjustment of machine tool ball screws

In the installation and adjustment of ball screws, in order to ensure that the transmission position accuracy of the ball screw feed system meets relevant standards, we must strictly control the axial displacement of the ball screw. Specifically, firstly, the assembly of the bearings inside the bearing seat of the servo motor end is crucial, as it plays an important role in the rolling screw drive and can effectively control the axial displacement of the ball screw, always keeping it within the standard range. Secondly, sufficient attention should be paid to the assembly work of the bearing inside the other end bearing seat, always ensuring that the axial displacement is maintained within 0.01. Only in this way can the accuracy and stiffness of the ball screw feed system be fully guaranteed. Once again, the pre stretching of the ball screw shaft is also a crucial step, which is an effective means to further improve the accuracy and stiffness of the ball screw feed system.

Simple operation of large ball screw

At present, large ball screws generally use medium frequency induction quenching. In production, it is often found that after intermediate frequency quenching (tempering), after grinding the thread, axial or mesh cracks often appear on the arc of the thread raceway through magnetic inspection. Even during the grinding process, they can be detected only by the naked eye, resulting in the scrapping of the screw. This not only causes direct economic losses to the enterprise, but also puts significant pressure on frontline production operators due to the multifaceted factors that cause this problem. The author has been engaged in the technical work of heat treatment for ball screws for a long time. Through the failure analysis and process tracing of a large number of grinding cracked large screws, the causes and control measures of such cracks were summarized, and the effectiveness was confirmed through mass production.
