Drum gear coupling

The drum type gear coupling is a rigid flexible coupling with radial, axial, and angular axis deviation compensation capabilities. Compared to the CL type straight tooth coupling, it has the advantages of compact structure, small turning radius, large bearing capacity, good transmission efficiency, low noise, and long maintenance cycle.

Characteristics of drum gear coupling (compared to straight gear coupling, it has the following characteristics)


1. Good bearing capacity. Under the same outer diameter of the inner gear sleeve and the larger outer diameter of the coupling, the load carrying capacity of the drum gear coupling is increased by 15-20% on average compared to the straight gear coupling;


2. Large amount of angular displacement compensation. When the radial displacement is equal to zero, the allowable angular displacement of the straight tooth coupling is 1º, The allowable angular displacement of the drum gear coupling is 1º 30 '', increased by 50%. Under the same modulus, number of teeth, and tooth width, the allowable angular displacement of drum shaped teeth is greater than that of straight teeth;


3. The drum shaped tooth surface greatly affects the contact conditions of the inner and outer teeth, avoiding the drawbacks of extrusion of the edge edges of the straight teeth under angular displacement conditions and stress concentration. At the same time, the actual effect mainly focuses on the friction and wear conditions of the tooth surface, reducing noise, and long maintenance cycles;


4. The tooth end of the outer gear sleeve assumes a horn shape, making it convenient to install and disassemble the inner and outer teeth.


5. The transmission efficiency is up to 90%. Based on the economic characteristics, drum shaped teeth have been widely used in many regions to replace straight tooth couplings.


There are various types and specifications of drum gear couplings, and they meet corresponding standards. The drum shaped gear coupling is characterized by high rigidity, flexibility, and inelasticity, so it is not suitable for machinery that requires strict vibration reduction, cushioning, and two shaft alignment requirements.
