Cost-effective problem of drum gear coupling

The cost-effectiveness of the coupling is obviously the price ratio, but the performance of the coupling is related to the stability of the transmission system and the service life and cost of use. The cost-effectiveness of the drum gear coupling is the key.First, there are many kinds of materials for drum gear couplings, such as 45#, 40CR, 42CRMO, etc. The corresponding heat treatment processes for these materials are different, such as normalizing, quenching and tempering treatment, high-frequency treatment, and nitriding treatment. Wait, most coupling users just ask what is the price of the specific coupling model?Although some coupling users mentioned the material of the coupling, they did not specify the overall strength performance requirements of the coupling (coupling tooth surface hardness, coupling matrix strength, etc.). At this time, The coupling manufacturers should communicate the coupling performance requirements with the coupling users, and determine the follow-up status of the coupling material and heat treatment process. For example, for large drum gear couplings above GICL15, The material utilization rate of cast steel materials and forging materials is very different, and the strength performance of forging materials is greater than that of cast steel materials, and the prices of couplings made of these two materials are obviously different, and the performance is different.Furthermore, the degree of structural optimization of the coupling of the same coupling model is different, including the modulus of the coupling teeth, the width of the teeth, the thickness of the flange, the diameter and number of the coupling bolts and the strength level , Tooth surface hardness and tooth side clearance, etc., these are the key issues related to the quality of the coupling.The coupling manufacturer must have a responsible coupling technician for the high-quality design of the drum gear coupling (according to the specific working conditions of the coupling user), and improve the coupling on the basis of the coupling standard At the same time of quality, the design and manufacturing process are optimized, the manufacturing cost is reduced, and the coupling with excellent cost performance is manufactured.
