The 701YB-45 coupling is a typical heavy-duty high elasticity coupling designed specifically for medium to high power transmission applications. Structurally, it usually consists of two high-strength cast steel or forged steel wheels, a pre compressed rubber elastic ring, and a quick detachable pressure plate assembly; The rubber component is embedded with multiple layers of nylon cord or aramid fiber, which not only ensures high torque transmission, but also has excellent shock absorption, noise reduction, and compensation capabilities. Unlike precision small couplings such as Huco, the shaft diameter range of 701YB-45 is generally between 80-220 mm, with a maximum allowable speed of 1500-1800 r/min, angular compensation of ± 1.5 °, and radial compensation of 2-4 mm. It can meet the safe operation requirements of large units under thermal expansion, foundation settlement, or installation errors.

Due to its high damping, lubrication free, and low maintenance characteristics, 701YB-45 is widely used in heavy industries such as power, petrochemicals, mining, metallurgy, and ships. In thermal power plants, it is used as a flexible connection between feed pumps, blowers, and electric motors, which can effectively absorb impact torsional vibrations during start stop processes; On mining belt conveyors or bucket wheel stacker reclaimers, it can compensate for axial displacement caused by temperature differences in long-distance transmission shaft systems; In the main propulsion system of large ships, it acts as an elastic link between the diesel engine and gearbox, reducing the risk of shaft resonance. During installation, simply move the hub axially to complete the replacement of the elastic body, greatly reducing maintenance time; Its rubber parts have a temperature resistance range of -40 ℃ to+120 ℃, and can provide oil resistant, seawater resistant, or flame-retardant formulas according to on-site requirements. In summary, the coupling 701YB-45 has become an indispensable key component in heavy-duty transmission chains due to its high reliability, long lifespan, and low maintenance costs.
