Requirements for the interchangeability of drum gear coupling parts

Drum gear couplingThe requirement of exchange of essential parts is worthy of our attention: every part of the drum gear coupling can be exchanged. If one of the parts is damaged, it can be replaced with a single spare part instead of all replacements, which saves money. Maintenance time is convenient for users.

In our country, the drum-shaped teeth of ordinary hard tooth surfaces are all treated by nitriding, and the hardened layer is small and the service life is not illusory. Erzhong Group Corporation and Erzhong Base Parts Factory have successfully developed carburized and ground in recent years. Hard tooth surface drum-shaped gear coupling, the product is used by Baosteel, Tianjin Steel Pipe Company, etc.

The problem of parts exchange: Because of the reasons for the cost of manufacturing, we use CNC machine tools to meet the requirements of the user, but from the perspective of the development situation, the exchangeability of the product parts should be guaranteed regardless of whether the user requires it or not. .

Production and sales and market speculation

In 1 years, we started to develop drum gear couplings and formulated the national standards and machinery industry standards. It has been nearly 2 years since its publication and implementation. It has completely replaced the original spur gear couplings because it is compact in structure and capable of carrying capacity. It is widely used in all kinds of mechanical transmission, and the coupling itself is a vulnerable part. It needs to be changed every XNUMX to XNUMX years, so the market demand The volume is large. The annual sales volume of drum gear couplings in Deyang alone is more than ten million yuan. It is estimated that the annual demand for domestic machinery, metallurgy, and heavy lifting and transportation will not be less than XNUMX million yuan. I hope that each manufacturer will increase it. Invest in skills, update equipment, and produce drum-shaped gear couplings that meet market demand as soon as possible, and make due contributions to the development of China's skills.
