Performance differences between helical gear reducers and worm gear reducers

Helical gear reducers and worm gear reducers are two common mechanical transmission devices. The performance differences between them are as follows:

Transmission efficiency: The transmission efficiency of helical gear reducer is higher than that of worm gear reducer, generally above 98%, while the transmission efficiency of worm gear reducer is generally above 90%.

Transmission ratio range: The worm gear reducer has a large transmission ratio range, which can generally reach 10-100, or even higher, while the helical gear reducer has a smaller transmission ratio range.

Stability: During the transmission process of the worm gear reducer, the transmission stability is relatively good and it is not prone to tooth skipping, vibration and other phenomena, while the transmission stability of the helical gear reducer is relatively poor.

Noise: The transmission noise of worm gear reducer is small, while the transmission noise of helical gear reducer is relatively large.

Volume and weight: Worm gear reducers are small in size and light in weight, while helical gear reducers are larger in size and heavier in weight.

Reliability: Worm gear reducers are simple to operate, are not prone to failure, and are also more convenient for maintenance. However, helical gear reducers have a short service life and require frequent replacement of gears.

Helical gear reducers and worm gear reducers each have their own advantages and disadvantages, and the appropriate mechanical transmission device should be selected according to the specific application and requirements.Helical gear reducers are suitable for occasions that require large transmission power and high transmission efficiency, while worm gear reducers are suitable for applications that require large transmission ratios, low noise, small size, and light weight.
