Structural Analysis and Application of Damping Shaft
The damping shaft is simply a shaft with damping. The shaft that bears both bending moment and torque in the rotating operation required to connect product parts is defined as the damping shaft. Then let's learn about the structural analysis and application of the damping shaft together!
damping shaft principle:
The principle of damping the rotating shaft is actually to generate friction force by pressing between the washer and the washer. The size of the friction is related to the number of washers installed and the degree of tightness of the nut. For example, when opening the laptop screen, the rotation axis of the laptop requires a certain degree of force, but this force may not be very large. In addition, even if the rotation is stopped, the screen will not shake up and down, left and right and fall, and the laptop screen can be fixed in the desired position through the friction of the rotating shaft.
Damping shaft structure:
Damping shaft structure according to the application scenario and classification, can be divided into single text damping shaft, lap damping shaft, shrapnel damping shaft,
Application of damping shaft:
Common damping shafts include notebook computer damping shafts, mobile phone damping shafts, bracket damping shafts, display damping shafts, camera damping shafts, point-of-sale machine damping shafts, etc.
damping shaft frequently asked questions:
The common problem of damping shaft is the wear of the gasket between the shafts, and it is also a common equipment problem in the use of the shaft. This is mainly due to the metallic nature of the inter-axle gaskets. Metal hardness is high, but poor escape (deformation can not be restored), poor impact resistance, poor fatigue resistance, easy to cause adhesive wear, abrasive wear, fatigue wear, fretting wear and so on. Most of the damping shafts are difficult to notice even if they are worn. They can only be noticed when the arbitrary stop amplitude of the damping is large, abnormal noise is generated, etc., but before people notice, most of the drive shafts are worn out, so the damping effect becomes smaller.
Damping shaft regular maintenance of the main role:
1. Damping shaft: Imported bearings must strive to maintain, overhaul and prevent accidents, ensure stable operation, improve consumption and economy, and maintain good original performance for as long as possible. According to the working specifications of the machine operating conditions, regular shutdown. The content includes monitoring of the operating state, replenishment or replacement of lubricants, and regular disassembly and inspection. The inspection items during operation include the rotating sound, vibration, temperature and lubricant status of the imported bearing.
2. Damping shaft inspection: bearing cleaning: when removing the bearing for inspection, the appearance of the imported bearing should be recorded first, the residual amount of lubricant should be confirmed, the lubricant for inspection should be sampled, and then the bearing should be cleaned. Ordinary use of gasoline, kerosene as a cleaning agent.
The cleaning of the imported bearing removed from the damping shaft is divided into rough washing and fine washing, which are put into the container respectively, and the metal mesh pad is placed to prevent the bearing from directly contacting the container dirt. During rough washing, if the bearing is rotated with dirt, the rolling surface of the imported bearing may be damaged, please pay attention. In the rough wash oil, with a brush to remove smooth grease, sticky matter, basic clean, into the fine wash. Fine washing refers to careful cleaning while rotating the bearing in the cleaning oil. In addition, wash oil should always adhere to clean.
The above is the analysis and application of the lower damping shaft structure. If you want to know more, please feel free to contact us!
