Publish Time: 2024-08-21
Bevel Gear plays an important role in mechanical transmission, and different helix angles give Bevel Gear transmission unique characteristics.
Bevel Gear transmission with a smaller helix angle has the following characteristics. First, its axial force is relatively small. This is advantageous in some installation occasions that are sensitive to axial force and can reduce the requirements for supporting structures. Second, it is relatively easy to process. Due to the small helix angle, the design and manufacturing difficulty of the tool is reduced, and the processing accuracy is easier to ensure. Furthermore, the overlap of this Bevel Gear transmission is relatively low, which may generate greater vibration and noise during the transmission process. However, in light-load and low-speed application scenarios, its performance is still stable and the cost is relatively low.
Bevel Gear transmission with a larger helix angle presents different characteristics. On the one hand, the overlap is higher. This means that during the transmission process, the contact time of the gear teeth is longer, the transmission is smoother, and vibration and noise can be effectively reduced. At the same time, the higher overlap also improves the bearing capacity of the gear, which is suitable for heavy-load and high-speed working conditions. On the other hand, a larger helix angle will produce a larger axial force, which requires a stronger support structure and a more complex axial positioning device. In addition, Bevel Gear with a larger helix angle is more difficult to process, and has higher requirements for processing equipment and processes, and the cost increases accordingly.
In practical applications, the selection of Bevel Gear transmission with different helix angles requires comprehensive consideration of multiple factors. If the transmission stability and load-bearing capacity are required to be high, and it can withstand large axial forces and high costs, then Bevel Gear with a larger helix angle is a better choice. In some cost-sensitive occasions with low axial force requirements, Bevel Gear with a smaller helix angle is more suitable. In short, understanding the characteristics of Bevel Gear transmission with different helix angles will help make reasonable choices based on specific application requirements to achieve the best transmission effect.
