الوصف

The expansion sleeve is a keyless coupling structure of transmission
 products, under the action of the axial force, expansion sleeve 
retracted outside up to the shaft and the hub tightly together to 
generate enough friction to transfer torque to achieve means is
 operated purposes.
Links centering performance, without heating the assembly to adjust the shaft and the hub of the corresponding location convenient, stress concentration, carrying capacity, torque, good stability, high accuracy, and do not damage the mating surfaces.
The products are widely used: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, engineering machinery, all kinds of machine tools and interchangeable mechanical transmission links.For example: pulleys, sprockets, gears, bevel wheel, impeller, timing belt pulleys, propeller, large and small fan, blower or direct links with the shaft and the hub as well as a variety of other transmission links, etc..
