What are the advantages of NGW112-110 planetary gearbox compared to ordinary gear gearbox
The NGW112-110 planetary reducer has significant advantages in structural design, transmission performance, and applicable working conditions compared to ordinary gear reducers, especially in high load, high-precision, and space limited application scenarios. The following is a specific comparative analysis:
1、 More compact structure, smaller volume, and lighter weight
NGW112-110 adopts the principle of planetary transmission, where power is evenly distributed through multiple planetary gears to achieve power splitting, making the structure more compact under the same power.
Compared to ordinary parallel axis gear reducers of the same specifications, its volume can be reduced by 30% to 50%, making it more suitable for equipment layouts with limited installation space.
For example, in mining conveying systems or metallurgical equipment, installation space can be saved without sacrificing output torque.
2、 Stronger load-bearing capacity and more stable transmission
The design of multi-point meshing of planetary gears allows the load to be shared by multiple gears, significantly improving the overall load-bearing capacity.
The NGW series can withstand large radial and axial loads and is suitable for working conditions with frequent impact loads, such as heavy-duty machinery such as crushers and roller presses.
Ordinary gear reducers are mostly single pair or two-stage gear transmissions, with concentrated loads, and are prone to local fatigue damage.
3、 High transmission efficiency and significant energy-saving effect
The single-stage transmission efficiency of NGW112-110 planetary gearbox can reach over 97%, and the two-stage series connection can still maintain around 94%.
Due to the long transmission path and high friction loss, the efficiency of ordinary gear reducers is usually between 90% and 93%, and long-term operation consumes more energy.
4、 Large transmission ratio and wide range
NGW112 is a two-stage deceleration model with a speed ratio of 110, belonging to the medium to high speed ratio range, and can achieve a larger transmission ratio through combination.
The new standard NGW series offers two-stage speed ratios from 14 to 125 and three-stage speed ratios from 180 to 2000, covering a much wider range than ordinary gear reducers.
If ordinary gear reducers need to achieve the same speed ratio, they often require three or even four stages of transmission, with complex structures and multiple fault points.
5、 Smooth operation with low noise
The evenly distributed structure of multiple planetary gears effectively balances centrifugal and inertial forces, with minimal vibration and smooth operation.
Although some data suggests that planetary gearboxes may have high noise levels (due to multi-point contact friction), modern precision machining technology has significantly reduced the noise level and actual performance is better than ordinary gearboxes of the same power.

6、 Low maintenance cost and high reliability
Although the initial procurement cost is slightly higher, due to its compact structure, good sealing performance, and high integration of the lubrication system, there is less need for daily maintenance.
Under continuous operation in the factory workshop environment, the average time between failures (MTBF) of NGW type reducers can reach more than 1.5 times that of ordinary products, making them suitable for production systems that are sensitive to downtime.
