There is a reason for the damage of every item, and there are corresponding reasons for the damage of the same drum gear coupling. Since the production of couplings, the company has been receiving every customer under the premise of quality, so that customers can use our products with more confidence and trust us more and more. However, this type of coupling has high rigidity, flexibility, and inelasticity, so it is not suitable for machinery that requires strict vibration reduction, buffering, and two-axis alignment.

Rigidity of drum gear coupling:

The drum gear coupling has a strong load-bearing capacity. Under the same outer diameter of the inner gear sleeve and the larger outer diameter of the coupling, its load-bearing capacity is increased by 15% to 20% on average compared with the straight-toothed coupling. ten. The tooth end of the outer tooth sleeve is in the shape of a trumpet, which makes the assembly and disassembly of the inner and outer teeth convenient. The transmission efficiency is as high as 99.7%. The drum-shaped tooth surface improves the contact condition of the inner and outer teeth, avoiding the disadvantages of straight tooth edge extrusion and stress concentration under the condition of angular displacement. At the same time, the friction and wear of the tooth surface reduce the noise and maintenance cycle long. Large amount of angular displacement compensation. When the radial displacement is equal to zero, the allowable angular displacement of the straight gear coupling is 1&ordm, while the allowable angular displacement of the drum gear coupling is 1&ordm30, which is increased by 50%. At the same modulus, In terms of the number of teeth and tooth width, the allowable angular displacement of drum-shaped teeth is larger than that of straight teeth.

Causes of damage to the drum gear coupling:

When using couplings, the equipment in the shafting system, such as diesel engines, gearboxes, shafting systems and highly elastic couplings, should complement each other in design and use, and their design and manufacturing levels are also relatively high, so that The quality of the designed ships is also very high. The main reason is that the shock absorber of the main engine sinks, which makes the shafting of the coupling appear asymmetrical, thereby increasing the additional torque, which makes the highly elastic coupling Fracture accident occurred due to fever. Because the scope of use of the coupling is relatively wide, it is widely used in many industries. It may be used improperly in specific situations, or it may not be considered carefully during use, which will also cause the coupling to be damaged during use.
