How to choose the right coupling
Coupling is a very important part of mechanical equipment in the operation and transmission process. The appropriateness and quality of the coupling will affect the operation of the equipment. The choice of coupling must consider many aspects. Now I will teach you how to choose the right one. Coupling!
The selection of the coupling must consider many factors, and the proper choice can exert the maximum function of the coupling. The specific selection process is as follows:
Coupling
Select the type and type of coupling:
There are many types of couplings, and the application characteristics of different couplings are different. According to the type of prime mover and working load, working speed, transmission accuracy, two-axis offset, temperature, humidity, working environment and other comprehensive factors Select the type of coupling.For example, when overload protection is required, safety couplings and long-distance transmission should be selected. When the axial size of the connection is large, it is advisable to choose an intermediate shaft type or an intermediate sleeve type.
Coupling torque calculation:
The power of the power machine in the transmission system should be greater than the power required by the work machine.According to the power and speed of the power machine, the theoretical torque T of the high-speed end connected to the power machine can be calculated; according to the working condition coefficient K and other related coefficients, the calculated torque T of the coupling can be calculated.
Coupling model selection:
According to the calculated torque Tc, an approximate nominal torque Tn can be selected from the standard series, and the selection should satisfy Tn≥Tc.The initially selected coupling size, that is, the shaft hole diameter d and the shaft hole length L, should meet the requirements of the main and driven end shaft diameters, otherwise the coupling specifications must be adjusted according to the shaft diameter d.It is a common phenomenon that the shaft diameters of the driving and driven ends are different. When the torque and speed are the same, and the shaft diameters of the driving and driven ends are different, the coupling model should be selected according to the larger shaft diameter.
Choose connection type:
The choice of coupling connection type depends on the connection type of the main and driven ends and the shaft. Generally, key connection is adopted, which is a unified key connection type and code. There are 3852 keyway types and 7 types specified in CGB/T 4. For keyless connections, the A-type key (flat key with single keyway) is more commonly used.
Pay attention to the quality of the coupling:
After determining the type and size of the coupling, pay attention to the product quality of the coupling manufacturer. The quality of the coupling will also affect the normal operation of the equipment, so we must pay more attention to the quality of the coupling. .
The above is the specific process of choosing a suitable coupling, which requires a certain degree of professionalism. If the customer is not clear about how to choose a coupling, we can calculate and plan a suitable product plan for you according to the demand situation provided, and provide you with high-quality Transmission parts such as couplings, pulleys, and taper sleeves.for reference only.
