NBD planetary gear reducer

The new NGW planetary reducer includes: NAD, NAZD, NBD, NBZD, NCD, NCZD, NAF, NBF, NCF, NAZF, NBZF, NCZF twelve series.

The new generation of star gear reducer is a brand new internal gear transmission. Its advanced transmission principle has won the National Invention Award and the invention patent rights of China, the United States and Britain. The Ministry of Machinery has issued the technical standard of the product. Can be widely used in metallurgy, mining, electrician, lifting, transportation, petrochemical, light industrial machinery and other equipment, especially in the field of heavy-duty continuous transmission, making breakthrough progress. The unitization, generalization and standardization of the internal transmission mechanism of the reducer are realized, and the reliability and carrying capacity of the product are greatly improved, and the different needs of users can be satisfied in a wider range.

Second, the characteristics

1. High transmission efficiency.

The force splitting structure of the internal meshing gear pair with high meshing efficiency transmits the torque and the rotational speed continuously and purely through the rolling bearing of the high load capacity, so that it has the advantage of high efficiency, and the HJ single-stage efficiency can reach more than 95%, HN type The efficiency can reach 93%, and the HH two-stage series efficiency can reach 90%.

2. High carrying capacity and compact structure.

Because the star wheel reducer has the advantages of "high speed ratio, large torque and small volume", its unit weight transmission torque is as high as 76N. Above m/kg, the transmission torque range is 0.098-1029kN.m; the transmission power range is 0.25-2000KW. It can be used for 30-50% of material in low-speed heavy-duty transmission field, which is about 40% lighter than other types of reducer. .

3. The transmission is stable and the noise is low.

The core unit of the reducer has up to 14-28 pairs of teeth meshed at the same time. Therefore, the product not only has the advantages of impact resistance, but also has the characteristics of reliable operation, stable transmission, low noise, long service life and long-term maintenance-free use of the gear.

4, the speed ratio range is large, the transmission ratio is wide.

The transmission ratio range is wide and dense. The transmission ratio of the first stage deceleration is 18-80, the transmission ratio of the series expansion stage is 75-600, and the transmission ratio of the two-stage series is 450-5000. The required ratio can be selected between 4-25000. Transmission ratio.

5. The core unit is modular and easy to maintain.

The reducer consists of a modular star wheel core unit with reliable performance and easy maintenance. Due to the precise structural parameters and thermal balance design, the reducer is made of high-quality materials and special processes. Most of the models allow the input speed to be as high as 3000r/min, which expands the range of current reducer series products.

Compared with the NGW planetary gear reducer, the star wheel reducer has the following significant advantages:

NGW planetary gear reducer: small transmission ratio, large transmission torque and large volume.

Star wheel reducer: large transmission ratio, large transmission torque and small volume.
