1. The helical gear precision planetary reducer has lower error than the spur gear precision planetary reducer. The helical gear planetary reducer uses helical gears. In terms of gear processing, the helical teeth require higher precision.In the gear meshing process, the helical gear meshes tighter than the spur gear, and the gap is smaller, so the accuracy is higher.

　　2. Helical gears have higher transmission efficiency, thanks to the processing complexity and the precision of the gear structure: helical gear precision planetary reducers perform better in transmission accuracy, especially on high-power planetary reducers. High torque and more stable transmission, low-power gear reducers will also use helical gears to reduce transmission errors; helical gears can effectively compensate for the error of each lamella gear. This compensation is very effective for the elasticity of the gear teeth. As a result, gears with an error of less than 10mm can average the error, thereby greatly reducing vibration, so that under load, they can run as smoothly as gears with an error of less than 1mm.Because at any instant, there will be two teeth meshing in about half the time (assuming the coincidence is about 1.5), which brings additional benefits in terms of strength, so the stress can be established at 1.5 times the tooth width instead of one tooth width On the basis of.

　　3. The helical gear precision planetary reducer runs more smoothly than the straight tooth precision planetary reducer, and the gear meshing degree is very high. When the gear rotates, it reduces the vibration of the reducer caused by heavy load.

　　4. The helical gear precision planetary reducer has a greater load. When the spur gear is meshed with the gear, only one tooth is kept in the state of occluding, while the helical tooth can always keep 2 to 3 gears in occluding together, so the load bears heavier.

　　5. Straight gear precision reducer is easy to process and the technology is relatively mature. The helical gear precision planetary reducer has high processing and assembly technology. Therefore, the price of straight gear is much cheaper than that of helical gear. Choose the right product according to the equipment accuracy and load requirements. It is difficult and uneconomical to use electromechanical integration to manufacture and assemble a large number of thin spur gears in assembly and manufacturing. Therefore, it is manufactured into a helical gear with the teeth along the spiral direction.Helical gears are not like spur gears, which can cause undesirable axial forces, but the benefits in terms of vibration and strength far outweigh the disadvantages caused by axial thrust and increased manufacturing costs.Therefore, without considering the cost, it is theoretically a good choice to use a helical gear precision planetary reducer instead of a spur gear precision planetary reducer transmission.
