Heavy Duty Zq400 / Zq400 Cylindrical Gear Reducer Soft Tooth Surface

ZQ400 cylindrical gear reducer-ZQ400 series cylindrical gear crane special reducer is mainly used in mining machinery, metallurgy, cement, construction, chemical, textile, light industry and other industries as a reduction device for lifting, transmission, and automatic mechanical transportation. Its role It connects the power part and the execution part in the mechanical transmission, and achieves the purpose of deceleration through it. Its use is very wide, the parts are durable, the maintenance is simple, the work is safe and reliable, and it has great versatility and interchangeability.
The ZQ400 cylindrical gear reducer is mainly used in hoisting machinery, but also in general equipment such as mining machinery, chemical industry, light industry, etc. The same type of crane reducer is mainly used in the lifting industry, and its applicable conditions are as follows:

1. The circumferential speed of the reducer gear transmission is not more than 4 m/s;
2, the speed of the high-speed shaft of the reducer is not more than 1500 rpm;
3, the reducer is used for forward and reverse rotation;
4, the working environment temperature of the reducer is -40℃ to +40℃

zq400 reducer model mark
ZQ-500-20-II-Z
(1) ZQ represents the reducer model
(2) 500 means total center distance (mm)
(3) 20 is the nominal transmission ratio
(4) II means that the assembly form is II assembly, for other assembly forms, see: installation dimensions of zq reducer
(5) Z means that the output shaft of the ZQ series reducer is a cylindrical shaft end. In addition, there are cross block shaft ends (code F) and gear shaft ends (code C, CA). For specific dimensions, see: ZQ series speed reducer Machine installation size

Zq400 reducer model example
The total center distance of the ZQ series reducer is 500mm, and the speed ratio i=40.17 (here we are talking about the actual transmission ratio, see the table below for the comparison between the nominal transmission ratio of the zq reducer and the actual transmission ratio), the assembly form is II, the output shaft It is a C gear type, and the specific model is marked as:
ZQ-500-40-II-C
