Nc Series of Planetary Gearbox for Decanter Centrifuge

NC-type planetary gearbox is used in decanter centrifuge, it owns the advantages of high carrying capacity, small diameter, compact structure, high transmission efficiency and big difference ratio range etc. It fits perfectly in the greater power, speed and differential speed, special in the centrifuge of high separation factors and large output torque.
 
NC-type gearbox generally use two drives, and input pulley generally have radial unloading device that it can bear greater radial force.
 
Precision hardened gear and internal gear, advanced design and  manufacturing process are coordinating with advanced processing equipment, the major parts have passed the balancing test that can meet the performance of the centrifuge under the high speed and small vibration frequency.
 
When NC-type gearbox is debugged, it should allow both ends of the outer cover to fix by balancing correction. After deduplication, corresponding mark should be signed on both ends of the cover and the corresponding position on the internal gear so that it can be disassembled again.


Ordering notice:
Please provide type, transmission ratio, and pulley parameters when you order the NC series products.
NC series products have two lubrication methods:
1. Input pulley unloading device has been added 3 # lithium base grease before they go out the factory, and grease can be injected after three months used. When too much grease injected, they may squeeze out from a crack in the pulley and the input cover after the initial operation, but it will not impact use.
2. Gearbox host uses thin oil lubrication and do not inject grease when leave the factory. So, it must be injected N220 extreme pressure gear oil (for winter) or N320 extreme pressure gear oil (for summer), or other lubricating oil has the same properties. The amount is 80% of the volume, or max after unbolt with the oil filling port 30 degrees from the highest point of vertical deflection. The oil should be changed after first 300 hours usage. Meanwhile, the residual oil should be removed completely during changing. After the first oil change, it needs to change the oil per every use of 1000 ~ 1500 hours (according to the working condition).
3. It is strictly prohibited running under the conditions of oil shortage.
We also can make non-standard design according to customer's requirements.
