1.High in transmission efficiency
2.Smooth and stable in run, low noise
3.Compact, light, long life, high bearing capacity

Products specification 

ZQA (PJ) type reducer is mainly used in lifting, mining, textile and light industries, the applicable conditions are as follows;

Reducer gear transmission circumference speed is not more than 160 m/s

High speed reducer shaft speed is not more than 1500 r/min

Reducer is used for the two to work

Reducer working environment temperature-40-+ 50 degrees Celsius

The speed reducer nine transmission ratio, nine configuration forms and three kinds of low speed shaft axis end form

Model have ZQA25, 35, 40, 50, 65, 75, 85, 100.

ZQA type reducer is in ZQ model type reducer design improvement on the basis of the gear, to improve the bearing capacity, and convenient for alternative ZQ model type reducer, in appearance, axial end and installation size under the condition of invariable, change gear shaft axis of the tooth material, 42 CrMo, big gear for 35 CrMo. The tempering hardness gear axle for 291 ~ 323 HB, big gear for 255 ~ 286 HB

Mark examples: ZQ model improved reducer always center from 500 mm, nominal transmission ratio 25, the first3 kind of assembly form, cylindrical axis, mark out for: reducer ZQA500-25-3 z.

2. The transmission ratio

ZQA type reducer is the actual ratio = 25.02 and ZQ model type reducer is = 23.34 differences. The rest the same

3. Appearance, axial end and installation size

ZQA type reducer, the appearance of the axial end and installation size and type reducer ZQ model the same
