Helical Bevel Gear Reducer for Construction Hoist or Passenger Hoist

1. Introduction

This Helical Bevel Gear Reducer is mainly applied in the construction hoist or passenger hoist, it has following features:

1. Vertical shaft helical bevel gearing arrangement gearbox.

2. Input shaft and output shaft are vertical in the helical bevel gear reducer.

3. No strict limitation to the mounting type.

4. Easily connected with and driven by different types of motors or other kinds of input power. The same type can be adapted to optioned powers of motors. It is therefore easy to realize different solutions for varied requirements.

5. Ratio: Wide range, very big final ratios can be obtained through combined unites to reach extremely low output speeds.

6. High Strength, Compact Structure: Housings are made of high strength cast iron. Gears and shaft gears are finished with gas carburizing process and precise grounding to sequentially get high loading capacity of per certain volume.

7. 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 25,000 hours. Vulnerable parts include lubricating oil, oil seals, and bearings.

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

9. Stable running, excellent performance, large load, low consumption, high efficiency, low temperature rise.
