How does the noise performance of hard tooth surface reducers and soft tooth surface reducers differ at different speeds

There are indeed differences in the noise performance of hard tooth and soft tooth reducers at different speeds. Let me help you sort out the key points:

1、 Hard tooth surface reducer

At high speeds: Noise is usually lower because hard toothed gears have high machining accuracy, can withstand larger loads and higher speeds, operate more smoothly, and produce less noise due to friction and impact. For example, at an input speed of 3000rpm, the noise level of the planet gearbox on the planet planet planet is 52dB~68dB.

At low speeds: the noise is relatively low, but attention should be paid to the installation method (such as horizontal or vertical) for its impact on lubrication and stress. Improper installation may increase noise.

2、 Soft tooth surface reducer

At high speeds: The noise may be higher because the hardness of the soft tooth surface gear is lower, and it is prone to wear at high speeds, resulting in increased noise. For example, the noise performance of the Shuntai ZQ250 soft tooth reducer may not be as good as that of the hard tooth reducer at high speeds.

At low speeds: the noise is low, and the soft tooth surface gear has good shock absorption performance, making it suitable for low load, low-speed applications such as packaging machines, conveyors, etc. For example, the Taiyuan ZSH soft tooth surface reducer has low noise at low speeds and strong environmental adaptability.

3、 Summary

Hard tooth surface: Low noise at both high and low speeds, suitable for high load and high-precision applications.

Soft tooth surface: The noise is higher at high speeds and lower at low speeds, making it suitable for low load and low-speed situations.
