NGW planetary gear reducer features and scope of application

一,NGW planetary gear reducer features and scope:

    The NGW planetary gear reducer is mainly constructed with a sun gear, a planetary gear, an inner ring gear and a planet carrier.

   In order to evenly distribute the loads of the three planet wheels, a toothed floating mechanism is used, that is, the sun gear or the planet carrier floats, or both the sun gear and the planet carrier float at the same time. The gears in the reducer are straight-tooth involute cylindrical gears. Has the following characteristics:

  1. Small in size and light in weight. Under the same conditions, it is 1/2 or more lighter than the ordinary involute cylindrical gear reducer, and the volume is 1/2 to 1/3.

    2, the transmission efficiency is high: single-stage planetary gear reducer reaches 97% ~ 98%; two-stage planetary gear reducer reaches 94% ~ 96%; three-stage planetary gear reducer 91% ~ 94%.

    3, the transmission power range is large: can be from less than 1KW to 1300KW, or even larger.

    4, the transmission range is large: i = 2.8 ~ 2000

    5, adaptability and durability. The main parts are made of high-quality alloy steel by carburizing and quenching or nitriding. The planetary gear reducer runs smoothly, with low noise and is used for more than 10 times.

    6, use and applicable conditions

The NGW planetary gear reducer has three horizontal series (NGW11-NGW121) and two levels (NGW42-NGW122) three (NGW73-NGW123). It is mainly used in metallurgy, mining, lifting and transportation machinery and equipment, and can also be used for power transmission under other similar industrial and mining conditions.

 

The maximum speed of the high speed shaft does not exceed 1500r/min

     The peripheral speed of the gear does not exceed 10m/s;

     Working environment temperature is -40 ° C -45 ° C;

     It can be operated in both forward and reverse directions.
