product details

Drum gear coupling is a kind of flexible coupling with high strength and high durability, which is suitable for medium and low speed transmission system. Its performance is better than that of rigid coupling, and it also has the function of compensating a certain relative displacement. Drum-shaped gear coupling is mainly suitable for medium and low speed transmission system, so it is generally used for large load and has certain impact and reciprocating transmission state.

Because of the advantages of the drum gear coupling and the working condition, it is required that the drum gear coupling should have high strength and fatigue strength, so the material selection and the corresponding heat treatment process of the drum gear coupling are very important.

Generally, drum gear couplings are forged with 45# steel and normalized, tempered and tempered with high frequency treatment of tooth surface. If the fatigue strength is more demanding, high-quality materials such as 40CR or 42CRMO should be selected, and the corresponding heat treatment process should be adopted. In special cases, the whole nitriding treatment should be adopted to enhance the overall table of the coupling. Surface hardness. Of course, the modulus of the teeth in the standard coupling and the clearance between the side of the teeth and the side of the outer teeth and the inner teeth are strictly regulated.
