Problem:
Gear motors installed in bucket elevators did not meet the requirements for reliability and safety. Their operation was accompanied by noise, vibrations, heating, and constant oil leakage. Gearbox breakages with complete equipment shutdowns also happened from time to time.
Solution:
Bonfiglioli A 90 gear motors are used as bucket elevator drives. These gear motors have a series of design features allowing all problems mentioned above to disappear. The main are as follows:
- The three-phase configuration of such gear motors increases the reliability of each unit and reduces the heating level of gear motors.
- The low-speed bevel gear and pinion on the second phase have an increased capacity and reduce operating noise.
- Gears and housing are of high processing precision
- Seals and bearings are of top quality
Result:
- Trouble-free operation of the bucket elevator
- No oil leaks
- No need for temperature control
- Significant noise reduction
- No vibrations
- 300% of oil saving during scheduled replacements
