Product introduction  :ZLY series reducer of hard toothed surface by external involute helical cylindrical gear reducer national professional standard ZBJ19004 production.

product features

1 .gear is made of high strength low carbon alloy steel after carburizing and quenching and become, tooth surface hardness up to HRC58-62, gear adopt CNC gear grinding technology, high precision, good contact.

2 transmission rate is high: single level greater than 96.5%, the double level greater than 93%, three more than 90%.

3 smooth running, low noise.

4 has the advantages of small volume, light weight, long service life, high carrying capacity.

5 easy dismantling, easy to install.

ZLY series reducer of hard toothed surface is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical etc..

The following conditions of Surface Hardened reducer ZLY series:

1 high speed shaft is not greater than 1500 rpm.

2 gear circumferential speed of not more than 20 m / s..

3 the working environment temperature of -40-45 ℃, if less than 0 ℃, before the start of the lubricating oil should be above preheat to 0 ℃, the speed reducer can be used for the operation of two opposite direction.
