What precautions must be taken before using a ball screw?

The ball screw is a typical example of contemporary technology. With the development of technology, a growing number of mechanical components have entered people’s lives. There is no denying that the ball screw plays an important and essential role in contemporary industry, it has so many advantages that it can be applied in many sectors.

A ball screw is a type of mechanical linear actuator that converts rotary motion into linear motion. This report will illustrate some precautions that must be taken before using a ball screw.

The types of a ball screw.

There are two most common types of circulation for ball screws: external circulation and internal circulation. The balls that are sometimes out of contact with the screw during the cycle are called external cycles; those that are always in contact with the screw are called internal cycles. The criterion for distinguishing between these two types of ball screws is the size of the connection.

How to maintain a ball screw?

Maintaining is an important part of using a ball screw. Although ball screws have a long service life, regular maintenance is necessary. It is understood that ball screws are prone to dust and foreign matter, rolling bearings also have the same problems. This problem will reduce service life. Therefore, it must be protected by a screw protector before using a ball screw.

In general, covers are available in the form of rigid spiral belts, telescopic sleeves, tapered sleeves, and folding plastic or artificial leather.

Besides, when ball screws are in long-term operation, regular greasing not only reduces friction but also improves efficiency.

The potential issues with a ball screw.

Although a ball screw has a lot of advantages, it also has some drawbacks that need to be noted.

One drawback of ball screws is that they are heavily lubricated. Regular maintenance is necessary, which is in to prevent corrosion and reduce friction. Only by ensuring efficient operation can the service life be extended. In addition to this, the choice of lubricant is also important. Noticeably, lubricants are divided into two main categories: lubricants and greases.

There are a number of potential problems that are likely to occur with the increasing use of ball screws. The faults caused by ball screws are varied and there is no fixed pattern. This is because identifying the cause of the malfunction is a prerequisite for quick and accurate repairs.

The following are common types of faults that require different repairs depending on the situation. There are three main types, inspection and repair of the ball screw nut pair and support system clearance, poor lubrication of bearings and screw nut pair, and servo motor drive problems.

For example, the automatic lubrication system of the ball screw nut is often blocked and cannot be automatically lubricated after a long period of operation. Therefore, the best solution is to add high-temperature resistant grease to the bearings and nuts.
