Product Details

The drum gear coupling is a high-strength and high-durability non-elastic element flexible coupling suitable for medium and low-speed transmission systems. Its performance is better than that of rigid couplings and it has the function of compensating for a certain relative displacement.Drum gear couplings are mainly used in medium and low speed transmission systems. Therefore, they are generally used for relatively large loads and certain impact and reciprocating transmission conditions.

      Due to the advantages and working conditions of the drum gear coupling, the drum gear coupling is required to have high strength and high fatigue strength. Therefore, the material selection of the drum gear coupling and The corresponding heat treatment process is very important.

      Generally, the drum-shaped gear coupling is forged with 45# steel and undergoes normalizing treatment + quenching and tempering treatment + tooth surface high frequency treatment. For higher fatigue strength requirements, high-quality coupling materials such as 40CR or 42CRMO should be used, and Corresponding heat treatment process, special conditions should use overall nitriding treatment to enhance the overall surface hardness of the coupling.Of course, the modulus of the teeth in the coupling standard and the tooth side clearance and the clearance on both sides of the external and internal teeth are strictly regulated.
