The universal coupling is used to connect two shafts together, so that the two shafts cannot be separated when the machine is working, and the two shafts can only be separated when the universal coupling is removed.
There are many types of universal couplings. When selecting applications, universal couplings need to determine the actual rotation speed of the transmission shaft, how much load it can carry, and the accuracy of installation required to connect the two shafts. Whether the shaft is stable and will not shake when rotating, the purchase price, etc.Users need to understand the performance of universal couplings and their respective characteristics when purchasing, and use a universal coupling suitable for their own equipment.If you choose to use it after purchase, you should report to the manufacturer in time if there is a problem, and do not wait for the final equipment to completely strike before refurbishing.In fact, the best thing is to make the manufacturer make a reasonable recommendation just like the manufacturer's description of the demand for the equipment.
Universal coupling is a machine used to achieve continuous rotation of two shafts of different mechanisms, and can reliably transmit torque and motionUniversal couplingComponents.The feature of its mechanism is that the two shafts are not on the same axis, and there is an angle with the axis.The biggest feature of the universal coupling is its large angular compensation capability, compact structure and high transmission efficiency.Universal couplings often encounter unbalanced transmission or vibration during operation.In order to improve the transmission efficiency of the universal joint and make the universal joint work smoothly, it is necessary to understand the reasons why this phenomenon occurs in order to find a solution.
Reasons that affect the unbalance of universal coupling:
1. The part design is deviated, or the material is unqualified, or it is caused by uneven wear.
2. The centering surface of the universal joint and the shaft is eccentric, causing imbalance.
3. The gap between the universal joint parts is unreasonable, or the accessories are unevenly distributed and asymmetrical.
Reasons affecting the vibration of universal coupling:
1. The balance sheet has not been compensated for dynamic balance.
2. The universal joints are not in the same plane.
3. Problems such as bending of the coupling,Universal couplingDestroy the original dynamic balance.
4. The spline is worn or the gap is too large.
Universal coupling is a kind of transmission parts. It uses the characteristics of its mechanism to make the two shafts not on the same axis, but at a certain angle for continuous rotation.The biggest feature of the universal coupling is its large angular compensation capability, compact structure and high transmission efficiency.There are many structural types of universal couplings, among which the cross shaft type is the most common, and the ball cage type is the second.In practical applications, universal couplings are also classified into heavy, medium, light and small according to their transmission torque.In order to better use the universal coupling, it is necessary to know what will cause damage.
1. Human factors: improper selection, poor machining accuracy of universal coupling, poor maintenance, poor alignment, etc.
2. Environmental factors: corrosion caused by deterioration of lubricating oil, corrosion of acid and alkali gases, etc.
3. Damage caused by wear: The universal coupling runs continuously in the machine, and wear occurs between the relatively moving components.
4,Universal coupling, Fracture: Exceeding the fatigue limit of the universal joint causes the component to break.
5. Connecting bolts: Improper design, selection and installation of connecting bolts.
Coupling is a mechanical part used to connect the driving shaft and the driven shaft in different mechanisms and make them rotate together to transmit torque.In high-speed and heavy-duty power transmission occasions, some couplings can also play a role in buffering, damping, and improving the dynamic performance of the shafting.The coupling consists of two parts, which are respectively connected with the driving shaft and the driven shaft.Generally, the power machine and the working machine are not directly connected, but are connected with the working machine by means of a coupling.
As a special type of coupling, the universal joint, due to its structural characteristics, makes the driving shaft and the driven shaft not on the same axis. When there is an angle between the axes, it can realize the continuous rotation of the connected two shafts and is reliable. To transmit torque and motion.The biggest difference of the universal coupling is that its structure has greater angular compensation capability, compact structure and high transmission efficiency.This is why universal couplings are so popular.
