Coupling Has Strong Flexibility
Coupling is a two-axis axial joint and the transmission of torque and movement of the components and has a certain compensation for the two-axis migration, in order to reduce the vibration of mechanical transmission system, reduce the impact of peak load, coupling should also have a certain buffer damping performance. Couplings sometimes also have overload safety protection. Couplings are part of the general mechanical parts of machinery that are used to connect two axes (active and driven) in different bodies to rotate them together to deliver torque. Voss Push in Couplings In the high speed and heavy load power transmission, some couplings have the function of buffering, damping and improving the dynamic performance of the shafting. The coupling consists of two halves, which are connected with the active shaft and the driven shaft respectively. Most of the general Power machine with the aid of coupling and working machines, Voss Push in Couplings is the mechanical product shafting transmission is the most commonly used joint components. In the late 20th century, domestic and foreign coupling products developed quickly, in the product design how to choose from a variety of varieties, performance of various couplings to meet the machine requirements of the coupling, for most designers, is always a problem.
Coupling has a strong flexibility, so allow to be connected to the rotor has a relatively large eccentricity, the vibration of the transmission is not sensitive, but due to complex structure, Voss Push in Couplings transmission torque is also small, generally used in small units.
The coupling is simple in structure, reliable in work, can transmit great torque, the connection rigidity is strong, and does not allow the connected rotor to produce relative axial and radial displacement, so the axial force and radial force can be transmitted in addition to the transmission torque. The rotor of the coupling can be shared with a thrust bearing. The main disadvantage is that the vibration of the connected rotor is transmitted to each other, Voss Push in Couplings and when vibration occurs, it is often difficult to find the cause. However, it is widely used in high-power units because of its high transmission power and some other advantages.
Coupling with the shaft, according to different forms can be divided into key connection, clamping-type connection and expansion ring connection, Voss Push in Couplings several forms have advantages but also have disadvantages. We introduce, convenient for the user to choose the connection form of coupling to reference, for better transmission.
1. Key connection: The transmission torque is big, the structure is simple, the cost is low, the space size is small, but the high speed rotates, its dynamic balance is not good. Key connections work in the same way as normal mechanical device keys.
2. Clamping-Type connection: simple structure, low cost, small space size. However, Voss Push in Couplings when the locking force is not enough, it will cause axial slipping between the coupling and the shaft. The clamping connection is through the fastening screws at both ends, the "opening" is closed, and the clamping torque is enlarged.
3. Expansion ring Connection: The transmission torque is big, the related processing size requirements are high, the structure is complex, the coupling volume is large. The work principle of the account ring clamping is: Locking through the end cover, when pressing the end cover, at the same time pressure tight the expansion ring, bulge ring and the outer ring, the shape is tapered, so when there is pressure, Voss Push in Couplings its inner ring will be pressed on the shaft, the outer ring pressure on the coupling sleeve. This completes the connection between the shaft and the coupling.
