Helical gear shaft

As an important mechanical transmission component, large helical gear shafts play an important role in mechanical equipment with their excellent meshing performance, high overlap and compact structural design. Our company can provide customized services according to customer needs.

Produce description

Large helical gear shafts have a sturdy structure and excellent performance. Its design fully considers the needs of mechanical transmission, and ensures the strength and wear resistance of the gear shaft through precise size control and material selection. In addition, the tooth shape of the helical gear shaft is at a certain angle to the gear shaft. This design enables the gear to run more smoothly during the transmission process and reduce vibration and noise.
Advantages and characteristics:
1. Excellent meshing performance: The meshing process of the helical gear is a smooth transition, and the force changes from small to large and then decreases, which enables the large helical gear shaft to maintain stable transmission performance under high-speed and heavy-load working conditions.
2. Overlap: The overlap of the helical gear shaft is large, which means that it has a stronger load-bearing capacity and can cope with larger loads. At the same time, the increase in overlap also extends the service life of the gear and improves the economy of the equipment.
3. Compact structure: Despite its large size, the helical gear shaft has a very compact structural design, which enables it to exert greater transmission efficiency in a limited space.
Processing technology:
The processing technology of large helical gear shafts is complex and delicate, including forging, heat treatment, rough machining, finishing and other links. During the forging process, the material is precisely controlled by temperature and pressure to achieve the ideal shape and performance. Heat treatment is used to eliminate the internal stress generated during the forging process and improve the strength and toughness of the gear shaft. Rough machining and finishing further ensure the dimensional accuracy and surface quality of the gear shaft.
In addition, with the development of modern CNC technology, more and more advanced processing equipment and technologies are applied to the production of large helical gear shafts, such as CNC milling machines, CNC grinders, etc. These equipment and technologies can greatly improve processing accuracy and efficiency and ensure product quality.
