The working principle of helical planetary gearboxes is to reduce the input speed and output greater torque through the meshing of helical gears and the revolution and rotation of planetary gears. The helical tooth surface of the helical gear enables multiple teeth to mesh at the same time, which improves the smoothness and reliability of the transmission. The layout of the planetary gears enables multiple planetary gears to rotate around the sun gear, further reducing the speed and increasing the torque.

1.Helical gear transmission: The design of the helical gear makes the transmission smoother, capable of bearing greater loads, and reducing noise. The tooth surface of the helical gear is spiral, and the contact line is longer during the transmission process, which can achieve multiple teeth meshing at the same time, thereby improving the smoothness and load-bearing capacity of the transmission.

2.Planetary gear transmission: Planetary gear transmission achieves efficient transmission of power in the planetary gear system through the synergy of multiple gears. The planetary gear not only rotates around its own axis, but also rotates around the axis of other gears with the planetary carrier. This transmission method has a complex structure but superior performance, and is widely used in heavy machinery and automobile manufacturing and other fields.

‌1.Core component: helical gear‌: The design of helical gear is the key to helical planetary gearbox. The tooth surface of helical gear is spiral. This special tooth shape makes the contact line longer during the transmission process, and multiple teeth can be meshed at the same time, thereby improving the smoothness and efficiency of the transmission. ‌

2.Planetary gear train layout‌: The helical planetary gearbox adopts a planetary gear train structure, which consists of a sun gear, a planetary gear and an inner ring gear. The sun gear is usually connected to the input shaft, and the planetary gear rotates around the sun gear and rotates at the same time, while the inner ring gear is fixed. This layout makes the reducer small in size and light in weight, suitable for use in environments with limited space. ‌

3.High-precision manufacturing‌: The helical planetary gearbox is processed by high-precision CNC machine tools to ensure that the size and surface quality of each gear reaches micron-level precision, ensuring the smoothness and reliability of the transmission. ‌

4.Multi-stage transmission‌: Through the combination of multi-stage planetary gears, a larger reduction ratio can be achieved to meet the needs of different application scenarios. This design not only improves the transmission efficiency, but also enhances the load capacity and can withstand large torque and impact.

‌5.Compact structure‌: The structural design of the helical planetary gearbox is optimized, making it smaller and lighter, and easy to install and maintain. This compact design has obvious advantages in aerospace, precision machinery and other fields.

‌6.Low noise design‌: The meshing characteristics of the helical gears make the helical planetary reducer generate lower noise during operation, which is suitable for occasions with high noise requirements, such as medical equipment, precision instruments, etc.

‌1.Regular inspection and maintenance‌: Regularly check the combination and fastening of the relevant parts of the gearbox to ensure that there is no looseness or damage. Clean the gearbox regularly and replace the gear oil to ensure cleanliness and avoid impurities. In addition, regularly check the sealing of the oil seal and gasket, and replace them when necessary to ensure the normal operation of the gearbox.

‌2.Optimize the operating environment and operating specifications‌: Ensure that the temperature of the gearbox operating environment is suitable and avoid excessively high or low temperatures. In high temperature environment, heat dissipation devices such as radiators or cooling fans can be installed; in low temperature environment, the preheating device can be used to ensure the normal flow of lubricating oil. Avoid overload and impact, use strictly according to the rated torque and power, and reduce the impact load during starting and stopping.

‌3.Use high-quality lubricating oil: Use the correct gear oil to ensure its cleanliness and avoid impurities. Change the lubricating oil regularly, and release the old oil while it is hot and clean it when changing the oil. Using high-quality gear reducer grease can reduce friction, prevent scratches, reduce noise, and prevent rust, but it should be noted that the working environment temperature does not exceed 80℃.

‌4.Keep the working environment clean: Prevent dust, impurities and other pollutants from entering the gearbox, increasing the risk of wear and corrosion. In a dusty working environment, use oil seals and dust seals with good sealing performance to prevent dust and moisture from entering. Clean the gearbox housing and the surrounding environment regularly to avoid accumulation of debris.

‌5.Reasonable design and material selection: The helical planetary reducer has a reasonable structural design, and the components have high matching precision, which can effectively reduce friction and wear. High-strength and high-wear-resistant materials such as high-quality alloy steel are used, and special treatments such as tempering and nitriding surface treatment are performed to enhance the strength and life of the product.
