Product Description: The new NGW planetary reducer includes twelve series: NAD, NAZD, NBD reducer, NBZD, NCD, NCZD, NAF, NBF, NCF, NAZF, NBZF, NCZF. The new generation of star wheel reducer is a brand new internal meshing gear transmission device that can be widely used in equipment such as metallurgy, mining, electrical engineering, lifting, transportation, petrochemicals, and light industry machinery, especially in the field of heavy-duty continuous transmission, achieving breakthrough progress. The modularization, generalization, and standardization of the internal transmission mechanism of the reducer have been achieved, greatly improving the reliability and load-bearing capacity of the product, which can meet the different needs of users on a larger scale.
2、 Characteristics:
1. High transmission efficiency. The force splitting structure of the internal meshing gear pair with high meshing efficiency is adopted, which continuously transmits torque and speed through the high load-bearing capacity rolling star wheel, thus having the advantage of high efficiency. The HJ single-stage efficiency can reach over 95%, the HN type efficiency can reach 93%, and the HH two-stage series efficiency can reach 90%.
2. High load-bearing capacity and compact structure. Due to the advantages of combining "high speed ratio, high torque, and small size", the star wheel reducer can transmit torque of over 76N. m per unit weight, with a transmission torque range of 0.098-1029kN. m; The transmission power range is 0.25-2000KW. It can save 30-50% of material when used in low-speed heavy-duty transmission fields, with an average weight reduction of about 40% compared to other types of reducers.
3. Smooth transmission and low noise. The core unit of the reducer has up to 14-28 pairs of teeth meshing simultaneously. Therefore, the product not only has the advantage of impact resistance performance, but also has the characteristics of reliable operation, smooth transmission, low noise, long service life, and long-term maintenance free use of gears.
4. Large speed ratio range and wide transmission ratio density. The transmission ratio range is wide and dense, with a transmission ratio of 18-80 for first stage deceleration, 75-600 for series expansion stage transmission, and 450-5000 for two-stage series transmission. The required transmission ratio can be selected between 4-25000 as needed.
5. The core unit is modular and easy to maintain. This reducer is composed of modular star wheel core units, with reliable performance and easy maintenance. Due to precise structural parameters and thermal balance design, as well as the use of high-quality materials and special processes, most varieties of this reducer allow input speeds up to 3000r/min, expanding the current range of reducer series products. Compared with NGW planetary gear reducers, star wheel reducers have the following significant advantages: NGW planetary gear reducers have smaller transmission ratios, larger torque transmission, and larger volume. Star wheel reducer: large transmission ratio, high torque transmission, small size.
