I. overview

Planetary gear reducer is a large and wide range of products, almost in all areas of the national economy, it is indispensable. This product is widely used in metallurgy, mining, overweight,

Transport, cement, construction, chemical, textile, printing and dyeing, pharmaceutical, food, environmental protection and other industries are suitable for the gear circle speed, 12m/s input speed is not big

1500r/min. working environment temperature of -40 degrees -45 degrees of transmission machinery, can be positive and negative direction of operation in two directions.

NGW series reducer is an involute straight tooth planetary gear reducer. With advanced technology and novel structure, it is mainly used in metallurgy, mining, cement, lifting and transportation,

Textile, printing and dyeing, chemical industry, light industry and other industries.

Two, characteristics

1 light weight, small size, compared with commonly used cylindrical gear reducer, weight reduction of more than 1 Tuo, volume can be reduced by 1/2-1

2, high transmission efficiency, single stage transmission efficiency of 0.97; two, optional 094, three, optional 0.91

3 drive power range from 1 kW to 1300 kw

4, the use of hardened surface technology, long service life, wide applicability.

Three, applicable conditions

1 high speed shaft, the maximum speed is not more than 1500 rev / min.

2 the circumferential speed of the gear shall not exceed 10 meters per second
