New Standard High Load Planetary Gearbox

Detailed Product Description

Features: Planetary gear speed reducers from SR are compact and light, comparing with shaft-fixed driving cylindrical gear reducers with hard tooth surfaces, the weight is 1/2~1/3 lower, and the volume is 1/2~1/3 less. It is of high driving efficiency, bearing capacity and driving power. The outline shapes are varied, and they will run steadilly and at low noise. It employs high-quality Alloy steel that is hardened and nitrided, so it isi of better performance.

Applicable range: Planetary gear speed reducers from SR are mainly applicable for more than 10 fields e. Gt. Metallurgy, mine, machinery, craning, transportation, light industry, textile, architrcture, building material, water conservancy, hydropower, pharmacy, food, energy, communications, logistic and environmental protection, etc.

The soeed for high-speed shaft is 1500-750rpm.
Peripheral speed of gear driving is not more than 15m/s for straigt gear, and not more than 20 m/s for bevel gear.
Can be used for run in both positive and negative direction.
