Plum coupling is a widely used coupling, also known as claw coupling, which consists of two metal claw discs and an elastic body. The two metal claw discs are usually 45 gauge steel, but aluminum alloys are also useful when sensitive loads are required.
The plum-blossom coupling has a simple structure, no lubrication, easy maintenance, easy inspection, maintenance-free, and can run continuously for a long time. Stable and reliable work, with good vibration damping, buffering and electrical insulation properties. Has large axial, radial and angular compensation capabilities. Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions. High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large bearing capacity, long service life, and are safe and reliable.
Scope of application
Plum couplings are widely used in CNC machine tools, CNC lathes, machining centers, engraving machines, CNC milling machines, computer gongs, metallurgical machinery, mining machinery, petroleum machinery, chemical machinery, lifting machinery, transportation machinery, light industry machinery, textile machinery , pumps, fans, etc.
Changzhou Tianniu Factory is a professional manufacturer of plum couplings, rigid couplings, universal couplings, cross slide couplings, winding couplings, bellows couplings, double membrane couplings and other products. The processing company has a complete and scientific quality management system.
