Botou drum gear coupling has the following characteristics: 
 Drum gear coupling), the compensation performance. Sleeve outer teeth drum gear coupling work to avoid internal and external teeth angular contact, allowing two axes of the axis of angular displacement of ± 1.5o, when the angular displacement in 2 ~ 3o reliable work is generally recommended to allow angular displacement 1o30 2o30; 
 2), able to withstand heavy load and impact load, the same angular displacement than the straight gear coupling carrying capacity increased by 15 ~ 20%; 
 3), high efficiency, up to 0.99; 
 4), good sealing, use, handling, maintenance is more convenient; drum gear coupling 
 Drum gear coupling with straight teeth coupling compared to the small size, carrying capacity, reliable work at high speed. For smelting, steel rolling, heavy machinery, steam turbine, petrochemical industry, shipbuilding industry. 
 Coupling expansion sets - bulging tight coupling is the world's widely used in mechanical couplings in the heavy load of an advanced basic components in the wheel hub and shaft connection, it is rely on Tighten high strength bolts to the inclusion surface pressure and friction to transmit the load is a key connection device. It is an economical, efficient and preferred connection methods, models z1, z2, z3, z4, z5, z6, z7, z8, the z9 z10 z20 full range of timely delivery, reasonable price. drum gear coupling
