Shaft to see how good quality is not good?

The rotating shaft is a shaft that is used to connect the parts and main parts of the product during rotating work, while bearing bending moment and torque. In everyday products, as long as a certain degree of rotation or flip is used, the axis of rotation will be used. For example, turning the upper and lower covers of notebook computers requires a rotating shaft, as well as the previous flip phone, desk lamp, newly folded mobile phone rotating shaft, TWS earphone charging box rotating shaft, etc. The application of rotating shaft can be seen everywhere in life. Therefore, it is particularly important to master the quality judgment of the shaft.

Do you know about the rotating shaft? What is the role of notebook computers?

The structural design of the shaft is an important step in determining the reasonable shape of the shaft and all structural dimensions. It is related to the type, size and position of the parts installed on the shaft, the fixing method of the parts, the nature, direction, size and distribution of the load, the type and size of the bearing, the blank, the manufacturing and assembly process, the installation and transportation of the shaft, and the shaft Deformation and other factors are related.

Characteristics of screw rod

Screw characteristics: 1 low friction loss and high transmission efficiency. Since there is a large amount of ball rolling between the screw shaft and the screw nut of the ball screw pair, a higher motion efficiency can be obtained. Compared with the sliding spiral pair in the past, the driving torque is less than 1/3, that is, the power required to achieve the same motion result is 1/3 of the sliding spiral pair. This is very helpful to save electricity.

Inspection and maintenance of screw rod

There are many kinds of faults caused by ball screw, and there is no fixed law. Some failures are progressive failures and require a development process. As the use time increases, they become more and more serious; sometimes they are sudden failures, generally without obvious signs, but they occur suddenly. This kind of failure is multifaceted and is caused by The interaction of unfavorable factors and the outside world. Therefore, determining the cause of the failure through correct detection is the premise of rapid and accurate maintenance.
