TL Elastic Sleeve Pin Coupling

Its core design is to place the polyurethane elastic sleeve ‌ on the pin bolt to achieve the connection of the two shafts. During operation, the compressive deformation of the elastic sleeve can absorb shock, attenuate vibration, and compensate for the ‌ radial, angular and axial minor deviations ‌ generated during installation. Its structure is simple and compact, consisting of two half couplings, pin groups and elastic sleeves. It features ‌ no lubrication, corrosion resistance and electrical insulation ‌. During maintenance, only the worn elastic sleeves need to be replaced without moving the main shaft of the equipment. It is suitable for transmission scenarios of ‌ medium and low speed ‌ and medium and small loads ‌, such as water pumps, fans, conveyors, etc., providing a cost-effective solution between vibration suppression and economy.

1.Elastic shock absorption and vibration damping

The bolts and pins are wrapped with ‌ polyurethane elastic sleeves ‌ to absorb the impact and vibration during transmission through compression deformation, reduce equipment noise and protect the connecting components.

2.Displacement compensation capacity ‌

It can automatically compensate for installation deviations in the axial, radial and angular directions, and adapt to slight shaft alignment errors.

3.simple and compact structure

It is composed of two half couplings, pin groups and elastic sleeves, with no complex components, small volume, light weight and low installation space requirements.

4.Maintenance-free maintenance

No need to add lubricating oil, avoiding oil contamination problems. The ‌ elastic sleeve is the only vulnerable part ‌. When replacing it, there is no need to disassemble the main shaft of the equipment, and the maintenance cost is low.

5. Corrosion resistance and insulation ‌

The elastic sleeve is made of polyurethane material, which is oil-resistant, acid and alkali resistant, and has electrical insulation properties. It can be used in damp or corrosive environments.

6. Economical and practical ‌

Low manufacturing cost, suitable for ‌ medium and low speed ‌, ‌ medium and small load ‌ scenarios (such as water pumps, fans, conveyor belts, etc.), with high cost performance.
