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.

As one of the important components in the field of transportation, the optimization of the performance of steel wheel forgings is crucial to ensure the safe and reliable operation of transportation vehicles. Heat treatment process plays a very important role in the manufacturing of steel wheel forgings. Through reasonable heat treatment process, the hardness, wear resistance, and fatigue resistance of steel wheel forgings can be improved, thereby optimizing their performance. The following is the relevant content on the heat treatment process and performance optimization of steel wheel forgings:
