All the gears and shafts we use are hobbed, ground and carburizing hardened. They are the top brand in the

domestic market.

The reducers include 4 kinds of series: ZDY(single-stage), ZLY(two-stage), ZSY(three-stage), ZFY(four-stage), and 57

kinds of sized, 54 kinds of speed ratios (People's Republic Of China major standard: JB/T8853-2001). They are

mainly used in metallurgy, mine, transportation, power, cement, building, chemical, textile and light industry.

Features:
1. Compared with the former reducers, the dimensions of hard teethface reducers are decreased by 56%, and the

weight are decreased by 40%, but service life are increased by 3~4 times, and carrying capacity are increased by

8~10 times.
2. Housing not inly has compact construction, artistic outline, but also has higher rigidity.
3. Main spare parts such as gears, shafts are made if high-strength alloy steel and treated with carburization,

quencher, gear grinding. The precision of gear is grade 6.

4. The running efficiency of each stage is 98%~99%.

5. The reducer can be assembled with backstop.

Products:
ZDY, ZLY, ZSY, ZFY

Equipment method:

1. Foot installment, 9 methods for installment
2. Backpressure valve can be equipped to meet the rotation with single direction.
3. Big power can be equipped to complete the capacity of heavy bearing.

Technique parameter:

Ratio:
single-stage:   1.25~6.3
double-stage:  6.3~20
three-stage:    22.47~100
