What are the advantages of universal coupling and how to choose it

Advantages of universal coupling:

1, the use of expansion sleeve to make the host parts manufacturing and installation are very simple. The machining of shafts and holes where expansion sleeves are installed does not require the same high precision manufacturing tolerances as interference fit. Expansion sleeve installation without heating, cooling or pressurizing equipment, as long as the bolt according to the required torque can be tightened. And easy to adjust, you can easily adjust the hub to the desired position on the shaft. Expansion sleeve can also be used to join parts with poor weldability. Our company specializes in the production of diaphragm coupling

2, the use of longer life, high strength. Expansion sleeve depends on friction transmission, there is no keyway to weaken the connected parts, also do not have relative movement, the work will not produce wear and tear.

3. When overloading the sleeve, it will lose the coupling effect and protect the equipment from being damaged.

4, universal coupling shaft can withstand multiple loads, its structure can be made into a variety of styles. According to the installation load, you can also use multiple expansion sleeve in series.

5, the swelling sleeve is easy to disassemble, and has good interchangeability. Because the expansion sleeve can be combined with the larger gap of the shaft hub, the disassembly will be loosened when the bolt, can make the coupling easy to disassemble. When bulging, the contact surface is tight and easy to stick without rust, and also convenient to disassemble.

How to choose the universal coupling correctly

1, high power, heavy parts can choose the tooth coupling. The bearing capacity of tooth coupling is better, and it has high elasticity and is not easy to be damaged.

2, for the universal coupling of the number of revolutions is more accurate, the balance force is also relatively high requirements, can choose the diaphragm coupling, diaphragm coupling accuracy is relatively high.

3, if you want to consider the cost, installation and easy to operate, you can choose the quincund-shaped elastic coupling, the structure of the quincund-shaped elastic coupling is simple, easy to operate, easy to install, and low cost, convenient maintenance.
