![LLA Rubber Flexible Couplings,LLA Tyre Coupling]()
LLA Tyre Coupling
The LLA Tyre Coupling uses two semi-couplings to connect both sides of the elastic tyre body through internal pressing plates and bolts, making it easy to replace the elastic tyre body. The LLA Tyre Coupling is a kind of high elastic coupling, with good damping buffer and superior offset compensation performance.The working temperature of 20~80 degrees Celsius, transmitting torque 10~20000NM, suitable for damp, dust, shock, vibration, reversing the changeable and frequent starting working conditions, and convenient assembly and disassembly, no lubrication, durable and reliable. Non standard couplings are made in accordance with special needs. In overloading work and half coupling, there will be no malignant accidents.View More -

UL Tyre Coupling
UL Tyre Coupling adopts the structure of vulcanizing and bonding the tyre body with the metal connecting plate with threaded holes, which is then directly connected to the two semi-couplings by bolts for torque transmission and other displacement compensation.UL Tyre Couplings are flexible shaft coupling. UL type tire has good buffering performance. Operating temperature: -20~+80℃. Torque range: 10~25000N.M.UL Tyre Coupling mainly used in damp, dusty, vibration working environment. Because the elastic part is the whole tire, so, easy to disassemble and assemble. No lubrication is required.View More
Rubber flexible coupling is a mechanical transmission device with rubber elastic elements as the core components, and belongs to an important branch of flexible couplings with elastic elements. It effectively compensates for axial, radial, and angular offsets between two shafts while transmitting torque through the high elastic deformation ability of rubber materials, and significantly reduces vibration and impact.
Typical structural composition
Metal connector: a main and secondary end flange usually made of cast iron or aluminum alloy material, connected to the shaft through keyway or bolt
Rubber elastomer: designed with a polygonal (6-angle or 8-angle) cross-section, bonded to metal parts through vulcanization process
Protection mechanism: V-shaped section protection ring design to prevent rubber from being damaged due to excessive deformation
Pre compression structure: Ensuring transmission stability through radial bolt pre tightening
Rubber components achieve displacement compensation through three deformation modes:
Shear deformation: cope with radial offset (up to ± 1.5mm)
Compression deformation: absorbs axial displacement (± 3mm)
Twisted deformation: Adjust angular deviation (± 4 °)
The high damping characteristics of rubber can absorb system vibration energy and reduce the transmission of impact loads by 15% -20%. Experimental data shows that its vibration reduction effect is more than three times higher than that of a non elastic component coupling.
Main types and application comparison
Compression type rubber coupling
Plum shaped elastic coupling: transmits torque through compression of convex claws and rubber pads, suitable for pumps and fans with moderate loads (<5000N · m)
Rubber sleeve column pin coupling: The column pin is covered with a rubber sleeve, with a compensation capacity of ± 1.2mm radial offset, and is commonly used in textile machineryShear type rubber coupling
Tire type coupling: Full rubber ring structure with angular compensation of up to 5 °, specifically designed for difficult installation and alignment of heavy equipment
Rubber metal ring coupling: metal ring and rubber are alternately laminated, with adjustable torsional stiffness, suitable for precision servo systems
