3.1 Performance characteristics of helical gears

3.1.1 Advantages Analysis

Helical gears have many significant advantages. Firstly, the meshing performance is good. The meshing process between the teeth of helical cylindrical gears is a transitional process, and the force on the teeth gradually increases from small to large, and then from large to small. This makes helical gears suitable for high-speed and heavy-duty situations. For example, in some large industrial equipment, helical gears can stably transmit enormous power, ensuring the normal operation of the equipment. Secondly, the high degree of coincidence increases the load-bearing capacity of the gears, thereby prolonging their lifespan. The degree of coincidence mainly depends on the meshing time, and the long meshing time and large contact area of helical gears reduce stress, smooth transmission, and increase their economy. In practical applications, some high-precision mechanical transmission systems use helical gears, which can improve the efficiency and stability of the entire system. Finally, the structure is compact, and the fewer the minimum number of teeth, the more compact the structure. This enables helical gears to play an important role in equipment with limited space, providing more possibilities for equipment design.

3.1.2 Disadvantages Response

Helical gears also have some drawbacks, such as large axial force and manufacturing difficulties. Axial force is harmful to gear transmission as it increases the friction between devices, making them susceptible to wear or damage. To reduce the influence of axial force, herringbone gears can be used, but manufacturing herringbone gears is more complicated and uneconomical. For the problem of manufacturing trouble, due to the complex tooth profile of helical gears, the manufacturing difficulty is high and the cost is relatively high. To solve this problem, on the one hand, we can continuously improve manufacturing processes, increase production efficiency, and reduce costs. On the other hand, it is possible to strengthen technological research and development, develop new manufacturing technologies and materials, and improve the performance and quality of helical gears.

3.2 Comparison of different types of helical gears

3.2.1 Involute helical gear reducer

The involute helical gear reducer has the characteristics of small size, light weight, high load-bearing capacity, high efficiency, long service life, easy installation, wide range of motor power, and fine gear ratio grading. In terms of application fields, it can be widely applied to devices that require deceleration in various industries. For example, in industries such as metallurgy, mining, lifting, light industry, chemical industry, transportation, and construction, involute helical gear reducers can meet the deceleration needs of different equipment, improving the operational efficiency and stability of the equipment. Its efficient transmission ratio and fine grading characteristics enable it to make precise adjustments according to different working conditions and adapt to various complex working environments.

3.2.2 helical gear worm gear reducer

The helical gear worm gear reducer adopts a motor direct connection form, with a structure of one stage helical gear and one stage worm gear transmission. The output is shaft mounted and has six basic installation forms. Its structural advantage lies in its ability to rotate forward and backward, and the helical gear adopts a hard tooth surface for smooth operation and high load-bearing capacity. The temperature range of the working environment is -10 ℃ to 40 ℃, which has the characteristics of large speed variation range, compact structure, and easy installation compared to similar products. In terms of applicable scenarios, it can be widely used as a reduction mechanism for various mechanical equipment such as metallurgy, mining, lifting, light industry, chemical industry, transportation, and construction. For example, in some equipment that requires frequent forward and reverse rotation, helical gear worm gear reducers can stably transmit power to ensure the normal operation of the equipment. Meanwhile, its six basic installation forms provide more choices for the installation of different devices, meeting various complex installation requirements.
