Introduction ：
The Cylindrical Gear Reducer with Hard Tooth Surface is produced according to the professional standard of  China (JB/T8853-2001 "Cylindrical gear reducer"), mainly including ZDY(single stage)ZLY(two stage)ZSY(three stage) three series are used in metallurgy, mining, transportation, cement, construction, chemical, textile, light industry energy and other industries. The speed of the high-speed shaft of the reducer is not more than 1500r/min. Reducer gear cycle speed is not more than 20m/s. The operating temperature of the reducer is -40~+45℃. Below 0℃, the lubricating oil should be preheated before starting.
Advantage :

1. Gear and gear shaft are made of high-strength low-carbon alloy steel by carburizing and quenching, and the tooth surface hardness reaches HRC54-62.

2.Gear grinding process, high precision, good contact effect

3.Transmission efficiency, single stage up to 98%, two levels up to 96%, three levels up to 94%.

4.Longer life than soft gear reducer
