ZZ planetary gear reducer

ZZ planetary gear reducer is widely used in machinery and equipment in mining, metallurgy, cement, light chemical, energy, building materials, lifting and transportation industries.

The main transmission structure of planetary reducer includes planetary gear, sun gear, internal ring gear.

ZZ type planetary gear reducer model, we PRM can design and manufacture planetary gear reducer includes: single-stage transmission(ZZD), two-stage transmission(ZZL),three-stage transmission(ZZS), single-stage derived transmission(ZZDP) and two-stage derived transmission(ZZLP). The two derived series have 1~4 assembly types respectively.

Technical data:

Transfer power: 0 kW-1800 kW

Transmission ratio：i=4-400

Maximum torque up t 2056 kN.m

Features of Planetary gear reducer

Planetary gear reducer is widely used in different industrials, it has the same quality as military grade reducer, but with the Competitive price as industrial reducer.

There are many advantages for Planetary gear reducer such as small volume body, small weight, high bearing capacity, long service life, smooth operation and low noise. also with power distribution, multi-tooth mesh unique characteristics. the max input power is up to 104kW.

Planetary gear reducer is easy to lubricate, it can be fully lubricated with Lubricating greases.

Non-standard design according to user requirement..

ZZ planetary gear reducer working principle

1.Internal ring gear is fixed, sun gear is driver and planet carrier is driven. Speed down transmission, speed ratio is 2.5-5, same transmission direction. 

2.Internal ring gear is fixed, sun gear is driven and planet carrier is driver. Speed up transmission, speed ratio is 0.2-0.4, same transmission direction.

3.Sun gear is fixed, ring gear is driver and planet carrier is driven. Speed down transmission, speed ratio is 1.25-1.67, same transmission direction.

4.Sun gear is fixed, planet carrier is driver and ring gear is driven. Speed up transmission, speed ratio is0.6-0.8, same transmission direction.

5.Planetary carrier is fixed, sun gear is driver, and ring gear is driven, speed up transmission, speed ratio is 1.5-4,opposite transmission direction.

6.Planetary carrier is fixed, ring gear is driver and sun gear is driven, speed up transmission, speed ratio is 0.25-0.67, opposite transmission direction.
