Based on the various advantages of the drum gear coupling, it can replace the straight gear coupling.In terms of angular compensation, drum gear couplings are much larger than straight gear couplings. Generally speaking, the tooth end of the outer gear sleeve of the drum-shaped gear coupling is in the shape of a horn, so the assembly and disassembly of the inner and outer teeth is very convenient. The angular displacement can avoid the disadvantages of edge extrusion and stress concentration of the straight teeth, the friction and wear of the tooth surface has been improved, and the long noise maintenance period has also been changed. When the radial displacement is equal to zero, the straight The allowable angular displacement of the gear coupling is 1o and the drum gear coupling is 1o30, which is a 50% increase in comparison. Under the condition of the same number of teeth and tooth width, the angular displacement of the drum tooth is larger than that of the straight tooth.7%. And the transmission efficiency of the drum gear coupling is CV Joint&boots Suppliers as high as 99. , So what are the advantages of drum gear couplings compared to straight gear couplings? What are the reasons why drum gear couplings replace straight gear couplings? Under the conditions of the same outer diameter and maximum outer diameter of the inner gear sleeve, the bearing capacity of the drum gear coupling is increased by 15 to 20% on the basis of the straight gear coupling. The contact conditions of the inner and outer teeth of the drum gear coupling are also greatly improved because of the drum tooth surface. Therefore, drum gear couplings are now being used at home and abroad instead of straight gear couplings
