Expansion coupling sleeve is an advanced basic component widely used in the international market for mechanical coupling under heavy load. In the connection of shaft and wheel, it is a keyless coupling device to realise load transmission by tightening the pressure and friction generated between the accommodating surfaces of high-strength bolts.
Low machining accuracy required for shaft holes, no need for heating/pressurising equipment, only need to tighten bolts diagonally according to torque.
Allows hubs to be repositioned on the shaft and supports couplings with poorly welded materials.
No keyway weakening structure, no relative motion wear, long life.
Automatic failure in case of overload protects equipment safety.
can withstand multiple loads, support the use of multiple expansion sleeves in series to increase the load.
Easy to disassemble (just loosen the bolts), anti-rust design of the contact surface to ensure repeated use.
