Do you know the difference between the spur gear and the helical gear of the planetary reducer?

The planetary reducer has the characteristics of small size, light weight, high carrying capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency, and safe performance. It is widely used in lifting transportation, construction machinery, Metallurgy, mining, petrochemical, construction machinery, light industry textiles, medical equipment, instrumentation, chemical industry, shipbuilding, weapons, aerospace and other industrial fields.Planetary reducers have straight teeth and helical teeth.Do you know the difference between them?I have sorted out the following three differences for your reference, hoping to help friends who buy planetary reducers.

1. Different structure

Straight tooth planetary reducer: the inner sun gear, large planetary gear, and transmission gear are all straight teeth.

Helical gear planetary reducer: the inner sun gear, large planetary gear and transmission gear are all helical gears.

Second, the accuracy is different

Straight-tooth planetary reducer: the first-level accuracy is within 10 minutes of arc, and the accuracy is within 6 minutes of arc.

Helical planetary reducer: the first-level accuracy is about 5 minutes of arc, and the accuracy is within 1 minute of arc.

3. The transmission torque and efficiency are different

Straight-toothed planetary reducer: Under the same motor shaft, the torque transmitted by the straight-toothed gear is lower than that of the helical-toothed planetary reducer, and the transmission efficiency is low.

Helical gear planetary reducer: Under the same motor shaft, the helical gear meshes, and the transmission torque is larger than that of the linear planetary reducer.The transmission device is stable, with high tensile strength and high efficiency.

Generally speaking, the precision of the helical planetary reducer is higher than that of the linear planetary reducer, and the deviation is small.In fact, the transmission system efficiency of the planetary reducer is higher.On the high-power planetary reducer, the torque is larger and the transmission system is more stable.Reducers with small output power will also use helical gears to reduce the error of the transmission system.
