What are the characteristics of drum gear couplings

　　The characteristics of drum gear coupling

　　1. The drum-shaped gear coupling has strong carrying capacity.With the same outer diameter of the inner gear sleeve and the large outer diameter of the coupling, the load-bearing capacity of the drum gear coupling is on average 15～20% higher than that of the straight gear coupling;

　　2. Large angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1º; while the allowable angular displacement of the drum gear coupling is 1º-30”, which is increased by 50%, at the same modulus , The number of teeth, and the width of the teeth, the angular displacement of the drum gear is larger than that of the straight tooth;

　　3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of squeezing the edge of the straight tooth under the condition of angular displacement, and stress concentration. At the same time, it reduces the friction and wear of the tooth surface and reduces the noise. , Long maintenance period;

　　4. The tooth end of the outer gear sleeve is in the shape of a horn, which makes the assembly and disassembly of the inner and outer gears easy
