‌‌1.Definition of helical planetary gearboxes

A helical planetary gearbox is a transmission device that combines the characteristics of helical gears and planetary gears. It converts the input power into actual movement that can achieve a specific purpose through the transmission of multiple gears. Helical planetary gearboxes usually include helical gears, planetary gears, bearings, shafts and other components, and have the characteristics of reverse synchronous speed and compact structure when transmitting power.

A helical planetary gearbox is mainly composed of an electric motor, a reduction gearbox and a planetary gear system. The electric motor provides power, the reduction gearbox works through the meshing of multiple gears, and the planetary gear system achieves multi-stage reduction through the combination of multiple planetary gears to improve transmission efficiency. The helical gear design makes the meshing smoother and effectively reduces noise and vibration.

1.High transmission accuracy: The helical gear design can increase the contact area of ​​the gears, reduce noise and vibration, and thus improve the transmission accuracy. The gear accuracy of the precision helical planetary reducer can reach micron level, ensuring high accuracy and low error during the transmission process. 

‌2.High transmission efficiency‌: The helical gear design can effectively reduce the friction loss during the meshing process, and the transmission efficiency can usually reach more than 95%. The combination of multi-stage planetary gears further improves the transmission efficiency and reduces energy loss.

3.Low noise‌: The meshing characteristics of the helical gears make the gear meshing smoother, effectively reducing the noise and vibration during operation, and is suitable for occasions with high noise requirements.

4.Strong load capacity‌: The multi-gear meshing design enables the helical gear planetary gearbox to withstand large torque and impact force, and is suitable for high-load conditions.

5.Compact structure‌: The helical gear planetary reducer has a compact structure, small size and light weight, which is suitable for use in environments with limited space. This design is not only easy to install and maintain, but also can achieve efficient deceleration and power transmission in a limited space.

6.High reliability‌: The use of high-quality materials and advanced manufacturing processes ensures that the reducer maintains stable performance during long-term operation. The characteristics of multi-tooth meshing can evenly distribute the load, reduce the force on a single gear, and improve the reliability and service life of the reducer.

7.Wide application: Helical planetary reducers are widely used in industrial automation, precision instruments, aerospace, new energy and other fields. Its high precision, high efficiency and low noise characteristics make it perform well in these fields.

1.Reduction ratio: The reduction ratio is one of the most important parameters when selecting a helical planetary gearbox. It determines the relationship between output speed and torque. Different application scenarios require different reduction ratios. For example, robot joints usually require a higher reduction ratio to achieve high-precision movement.

2.Rated torque: The rated torque refers to the maximum torque that the reducer can withstand under normal working conditions. When selecting, make sure that the rated torque of the reducer is greater than or equal to the torque required by the equipment.

3.Input speed: The input speed refers to the speed of the motor or other drive device. Different input speeds will affect the output performance of the reducer, and the appropriate input speed range needs to be selected according to actual needs.

4.Output speed: The output speed is the actual speed of the reducer when it is working. Select the appropriate output speed according to the operating speed requirements of the equipment.

‌5.Installation method‌: There are many installation methods for helical planetary gearboxes, such as flange installation, shaft installation, etc. Choosing the right installation method can ensure the perfect match between the reducer and the equipment‌.

‌6.Protection level‌: The protection level determines the dust and water resistance of the reducer. For occasions with harsh working environments, choosing a reducer with a high protection level can extend its service life‌.

‌7.Lubrication method‌: The lubrication methods of helical planetary gearboxes include oil bath lubrication, grease lubrication, etc. Choosing a suitable lubrication method can improve the operating efficiency and life of the reducer‌.

‌8.Working environment‌: Different helical planetary gearboxes adapt to different working environments, such as high temperature, low temperature, strong magnetism, etc., and need to be selected according to actual needs‌.

‌9.Accuracy requirements‌: The accuracy requirements of the helical planetary gearbox are also one of the important considerations. The higher the accuracy, the longer the service life‌.
