I. Overview

　　This standard includes two series of single-stage and two-stage NGW-L vertical traveling planetary gears: mainly connected to metallurgy, lifting, transportation, light industry, and general machinery and equipment.

　　The applicable conditions are as follows

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

　　2 Gear circumferential speed does not exceed 15m/s,

　　3 The working environment temperature is 40℃-45℃

　　4 It can run in both directions.

　　XNUMX. Model and mark

　　The model of the reducer includes the series code of the reducer, the frame number, the number of transmission stages, and the nominal transmission ratio.
