As the "heart" of industrial transmission systems, the performance of reducers directly affects equipment efficiency, energy consumption, and lifespan. In the face of different working conditions, incorrect selection may lead to a cost increase of over 30%.

1、 Gear reducer: the leader in the heavy-duty field
Technical Characteristics

Transmission efficiency: helical gear>95%, spur gear 92% -94%

Torque range: Single stage can reach 200kN · m

Impact resistance: Gear tooth surface hardness HRC58-62 (carburizing and quenching process)

Classic applications

Mining ball mill: three-stage gear reduction, output torque ≥ 650kN · m

Cement vertical mill: hard toothed gear+forced lubrication system, with a lifespan of over 100000 hours

Port unloader: anti salt spray corrosion coating, suitable for environments with humidity>90%

2、 Planetary gearbox: the benchmark for precision transmission
Accuracy index

Backgap level: P1 level ≤ 3 arc minutes, P0 level ≤ 1 arc minute

Repetitive positioning accuracy: ± 0.001 ° (for machine tool turntable applications)

Non standard automation field

Six axis robot joint: average reduction ratio of 80-120, instantaneous overload capacity of 200%

There are many applications of various high-precision non-standard devices.

Selection trap

Avoid axial force exceeding 5% of rated load (causing deformation of the planetary carrier)

High dynamic scenes require verification of angular acceleration (>500rad/s ² requires special design)

3、 Worm gear reducer: self-locking safety guard
Core advantages

Self locking condition: Reverse efficiency<35% when speed ratio ≥ 40

Noise reduction performance: Sliding friction noise ≤ 65dB (A), better than gear transmission by 10dB

Used for lifting and dragging devices with high loads

Cycloid pinwheel reducer: impact resistance expert

Innovation Structure

Cycloid wheel: Double eccentric structure, theoretical zero backlash (actual ≤ 2 arc minutes)

Needle tooth shell: elastic pin shaft design, increased impact load absorption rate by 40%
