Product description

Output Torque top to 18000N.m solid shaft helical gear reducer gear box

Product description:

1. Highly standard modular designed

The products are easily connected with and driven by different types of motors or other kinds of input power. The same type geared motor can be adapted to optioned powers of motors. It’s therefore easy to realize different solutions for varied requirements.

2. Ratio
Featured many closely divided ratios and wide range of them. Very big ratios can be obtained through combined units to reach extremely low output speeds.

3. Mounting arrangement
No strict limitation to the mounting arrangement.

4. High strength,compact dimension
Housings are made of high strength cast iron. Gears and shaft gears are finished with gas carburising process and precise grounding to sequentially get high capacity of per certain volume.

5. Long service life
under the condition of accurately selecting type size and the normal maintenance and use, main components (except those easily-disabled parts) can last as long as up to more than 25000 hours. Easily disabled parts include lubricating oil,oil seals, and bearings.

6. Low noise
All key components are finished by precisely machining, accurate assembly, and finally tested,and therefore, fairly low noise is reached.

7. High efficiency
The efficiency of gear unit can reach 95%. The efficiency of worm gear can reach 89%

8. Large radial loading ability
