Four Methods of Judgment and Purchase of Rotating Shaft Quality
The rotating shaft refers to the shaft required to connect the main parts of the product parts to bear both bending moment and torque during the rotating operation. In everyday products, the axis of rotation is used when rotating or flipping with a certain degree of force. For example, the upper and lower covers of a notebook need hinges, which can be seen everywhere in life, such as previous flip phones, brackets, new folding mobile phone hinges, TWS headset charging box hinges, etc. Therefore, it is particularly important to master the quality judgment of the rotating shaft. Then, let's understand the four methods of judging and purchasing the quality of the rotating shaft!
Four ways to judge the quality of the shaft: image description
1 Look at the rotating shaft technology
Check whether the surface treatment of the rotating shaft is smooth and flat. Generally better quality shaft technology is more perfect. The appearance shall be free of burrs, the coating shall have strong writing force and no black blocks. When the shaft is closed, whether the torque is uniform or not will directly affect the service life. This also directly indicates the level of shaft factory technology manufacturing.
2. see the shaft material
The shaft is a component that is used more frequently in the finished structural part. Therefore, what kind of material is selected and easy to rust has become an important basis for judging the quality of the shaft. The common rotating shaft used for the rotating shaft is made of imported SK7 and stainless steel, which has high wear resistance and can improve the anti-corrosion function of the rotating shaft. However, the ordinary rotating shaft uses inferior stainless steel, or it is out of hand during the manufacturing process, and the rotating shaft is rusted during use.
Three. Experimental data for measuring shafts
The two methods are only through the surface of the initial determination of the quality of the rotating shaft is good or bad, directly through the experimental data to determine the quality of the rotating shaft. The rotating shaft usually uses good materials and excellent technology. The life test of the rotating shaft reaches about 3W times, and the attenuation rate of the torsion force is within 20%. On the contrary, a generally inferior rotating shaft has a short life and may be easily broken during use.
The shaft plays a great role, and the selection of the shaft will directly affect the life and use experience of the finished product. Therefore, please pay attention to the following points when planning to purchase a shaft.
Matters needing attention in the purchase of rotating shaft:
1. Understand the qualification, economic strength and pre-sales and after-sales service content of the rotating shaft factory. avoid unnecessary trouble
2. Test reports and environmental protection reports are required to ensure that the quality of the shaft meets the requirements of use.
3, clearly choose the use requirements of the shaft, choose the right is not the higher the price, the better the quality, reduce unnecessary waste.
The above introduction is the four methods of judging and purchasing the quality of the rotating shaft. If you want to know more about the relevant knowledge of the rotating shaft, please feel free to contact us!
