What are the principles and characteristics of the locking sleeve?

2021-09-21 12:00:00

It is an advanced basic component that is widely used in the world for mechanical coupling under heavy loads. In the coupling of wheels and shafts, it is one of the means to achieve load transmission by tightening high-strength bolts to generate pressure and friction between the containing surfaces. This kind of keyless coupling device is a transmission part product with a keyless coupling structure. Under the action of axial force, the inner and outer sleeves of the expansion sleeve contract inward and outward to make the shaft and the hub fit closely to produce enough friction to Transmit torque, so as to achieve the purpose of mechanism operation.

Therefore, the locking sleeve has the following characteristics:

1. The centering performance of the connection is good; no heating is required during assembly;

2. It is convenient to adjust the corresponding position of the shaft and the hub;

3. There is no stress concentration; strong bearing capacity; large torque; good stability; high precision; no damage to the mating surface.

4. Internal and external swelling type;

5. Rich in size and structure, suitable for various structural forms;

6. High transmission accuracy, no gap transmission, no noise;

7. Realize overload protection, easy to disassemble and assemble;

8. High-performance screws, using high-performance 12.9-level screws, imported quality

Locking sleeves are widely used in

Packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, engineering machinery, various types of machine tools and interchangeable machinery transmission connection. For example: belt pulleys, sprockets, gears, umbrella wheels, impellers, synchronous belt wheels, propellers, large and small fans, blowers or directly connected to shafts, hubs and other various transmission connections.
