The plum blossom coupling is a widely used 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, easy maintenance, no need for lubrication, convenient inspection, maintenance-free, and can run continuously for a long time. It has good vibration damping, buffering and electrical insulation properties, and works stably and reliably. Has large axial, radial and angular compensation capabilities. 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 coupling, rigid coupling, universal coupling, cross sliding coupling, winding coupling, bellows coupling, double membrane coupling and other products. The processing company has a complete and scientific quality management system.
It can produce dozens of varieties of star couplings of various styles. The company undertakes the design and manufacture of various non-standard couplings. Short construction period (production cycle 4-7 days), reliable quality, reasonable price, completely replace imports, sufficient inventory, and sufficient product supply.
