Why does the metal shaft vibrate?
Hardware spindle as we all know, rotation is a product can be connected, so that the product can rotate, twist. We all know that there is a rotation axis, damping rotation axis, table lamp rotation axis, laptop rotation axis. According to the characteristics of rotation axis, it can be divided into axial rotation axis, torsional rotation axis and transverse rotation axis. The horizontal axis is closely related to the product. In the process of working, the rotating shaft sometimes appears vibration, so what is the cause of vibration? What does it do? A lot of people have this problem. Today, I'm going to explain to you why there are synchronous and subsynchronous vibrations in the form of vibrations on the axis of rotation. The reason of synchronous vibration is that due to incorrect coupling, sub-synchronous vibration is very harmful. As a sudden sub-synchronous vibration, if it occurs at high speed, the rotor will be out of balance, and it is likely that the rotor speed will be lower than the rotor shaft, resulting in a disconnection accident. Hardware shaft, when the shaft vibration, be sure to stop for testing, if it is synchronous vibration, the coupling performance is good, if it is synchronous vibration, then the shaft should be replaced. If you do not know what can find professional manufacturers for testing, replacement and so on. Small shaft large function, safe and reliable shaft makes you safer. Shaft, in machinery is Z common, can be used to connect the product parts of small parts, machinery common shaft, spindle, drive shaft and so on. These three are common mechanical shafts, but the range of use and function are not the same. Today's small series of rotating shafts will give you an analysis of the shaft, spindle and drive shaft.

1. Spindle: The shaft used to support rotating parts but can only bend. Spindles are divided into rotating spindles and fixed spindles, spindles that can be turned, such as that of railway vehicles, and spindles that cannot be turned, such as that of pulleys.

2. Transmission shaft: high-speed, small bearing rotation shaft. Before leaving the factory, the balancing test should be carried out and adjusted on the balancing machine.

3. Rotating shaft: It is a kind of shaft that can bear both bending moment and torque. This is a necessary part of connecting products. Common mobile phone shaft, laptop shaft, portable dvd shaft, led table lamp shaft, etc.
