1、 Design and Manufacturing Factors

Structural Design

A reasonable structure can make the coupling uniformly stressed during operation. For example, a coupling with a good shaft offset compensation structure can reduce additional stress caused by shaft misalignment, thereby extending its service life. However, unreasonable structural design may lead to stress concentration, which can easily cause fatigue cracks in local areas and reduce service life.

In industrial production, as a key component connecting different shaft systems, the correctness of the selection of Dalian couplings directly affects the performance and stability of the entire mechanical system. The following are the key indicators and precautions for choosing a coupling.

Helical gears commonly come in the following types:

I. Left-Hand Helical Gears and Right-Hand Helical Gears

Determine appropriate parameters such as module, number of teeth, and helix angle. The larger the module, the higher the strength of the gear, but it will also increase the weight and cost. The selection of the number of teeth should consider the transmission ratio and contact ratio. 

（1） Strong carrying capacity

Due to its large size and reasonable tooth profile design, it can withstand high torque and radial force, making it suitable for heavy-duty transmission applications.

In many fields of modern industry, large helical gears play an important role. They are widely used in the transmission systems of large equipment such as heavy machinery, ships, and wind power generation. Their manufacturing process and performance characteristics directly affect the operational efficiency, stability, and reliability of the entire equipment.
