Output Speed(r/min): 1-1200
Transmission Ratio: 1.25-450
Output Torque (N.m): top to 952000
Motor Power (KW): top to 4800
- Structures: horizontal mounting, vertical mounting, and outputs can be solid output shaft, hollow output shaft, hollow shaft with shrink disc
- Modular design enables standardization of many basic components, interchangeability improved and quality guaranteed;
- Sound-absorbing and large surface of housing adopted to reduce noise, and big fan and new-type fan cover help to reduce temperature
- Gears and gear shafts made of high-quality low-carbon alloy steel 20CrMnTi, output shaft made of high-quality low-carbon alloy steel 40Cr, the gearbox housing made of high-strength casting iron HT250, may also adopt better material as requested;
- High efficiency up to 98%per stage, low noise <70-80dB, and temperature rise <40-50a , and high precision grade up to 6 or better of ISO1328;
- Gears and gear shafts through carburizing and quenching then advanced fine profile grinding process to improve stability and transmit power more efficiently, gearbox housing through aging treatment then annealing to relieve stress twice, therefore the bearing capacity very high;
- Best China bearings used on products, may apply other bearings like SKF, NSK and FAG, and double-lip oil seal make sure no oil leak;
- Every gearbox 100 percent tested prior to delivery.
