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.
How does the shaft look good? Four ways to judge the quality of the shaft:
First, look at the flow of the axis of rotation
Check whether the surface treatment of the rotating shaft is smooth and flat. General good quality of the shaft process is perfect. Look at the appearance, should be no burr, plating adhesion is strong, no black. When the shaft is closed and opened, whether the torque is uniform will directly affect the service life, which also directly reflects the manufacturing level of the shaft manufacturer.
Second, look at the shaft material
The shaft is one of the most frequently used parts in the finished structural parts, so the most important basis for judging the quality of the shaft is whether it is easy to rust or wear. Ordinary high-quality rotating shaft is made of imported SK7 and stainless steel, which has strong wear resistance and can improve the anti-corrosion function of the rotating shaft, while ordinary rotating shaft is made of inferior stainless steel or cut corners in the production process, resulting in rust or corrosion after the rotating shaft is used for a period of time.
Third, the experimental data of the measurement axis
The first two methods only preliminarily judge the quality of the rotating shaft through the surface, and the most direct method is to judge the quality of the rotating shaft through experimental data. The rotating shaft is generally made of high-quality materials and exquisite craftsmanship. The shaft life test can reach about 3W times, and the torque attenuation rate is less than 20%. On the contrary, the ordinary inferior shaft has a short service life and is easy to break during use.
Fourth, look at the shaft brand
The establishment of the shaft brand must first ensure the quality, so when buying, it is best to choose brand products with good reputation.
The shaft plays a big role. If the shaft is not selected well, it will directly affect the life and experience of the finished product. Therefore, when buying a rotating shaft, you should also pay attention to the following points in advance. There are three points to note when selecting a shaft:
1. Understand the qualification, economic strength and pre-sales and after-sales service of the shaft manufacturer to avoid some unnecessary troubles.
2. Request test reports and environmental protection reports to ensure that the quality of the shaft meets the requirements of use.
3. Clear the use requirements of the selected shaft. Choosing the right does not mean that the higher the price, the better the quality. Reduce unnecessary waste.
The shaft plays a very important role in industrial products, if you need to know what the shaft. You can contact us. We are the production of rotating shaft manufacturers, with many years of production experience, will explain more about the shaft of knowledge, to facilitate you to better purchase.
