Fenner Helical Worm Gearbox Replacement
Our company offers several advantages in replacing Fenner brand gearboxes:
- High-quality replacements at affordable prices
- Our products are replacement parts, not original equipment. If you require original equipment, please contact the original supplier for purchasing.
The Worm Reducer is composed of the following parts:
- Worm shaft
- Worm wheel
- Gear housing
- Output shaft
- Bearings
- Sealing components
Installations
The installation of the reducer is crucial for its performance. Here are the installation instructions:
- Shaft Mounting: Ensure the shaft and the gearbox unit hole are clean and free from burrs. Apply a sufficient amount of lubricating oil to the shaft and hole to aid assembly and prevent friction corrosion. Slide the unit onto the drive shaft and fit the key.
- Foot Mounting: Securely mount the unit on a sturdy structure. Install the output extended shaft if required. The connection between shafts should use flexible couplings, and ensure the shaft deviation is within the coupling's tolerance. When installing pulleys or sprockets on both shafts, it is recommended to mount them closer to the gearbox. Do not strike the shaft when installing or removing transmission components, as it may damage the bearings.
The lubrication and maintenance of the Worm Reducer are essential for its optimal performance. Here are the lubrication and maintenance guidelines:
- Oil Change: Gearboxes of size 870 and 871 are lubricated for life, excluding cases where they operate in explosive environments. All other sizes of gearboxes require oil change based on the working temperature of the equipment. Half of the oil should be replaced in new gearboxes after 1000 hours of operation or one year, or as per the specified service life.
- Additional maintenance guidelines can be expanded upon based on your specific requirements.
Possible issues that may arise when using the Worm Reducer, their causes, and solutions are listed in the table below:
| Issue | Cause | Solution |
|---|---|---|
| Noise or vibration | Lack of lubrication or misalignment | Ensure proper lubrication and alignment |
| Overheating | Excessive load or lack of lubrication | Reduce the load or increase lubrication |
| Leakage of oil | Damaged seals or improper assembly | Replace seals or ensure proper assembly |
| Loss of efficiency | Wear and tear of gears or misalignment | Inspect and replace worn gears and align properly |
| Difficulty in shifting gears | Sticky or damaged gear teeth | Clean or replace gears as needed |
| Shaft breakage | Excessive load or improper installation | Reduce the load or ensure proper installation |
| Severe wear of bearings | Insufficient lubrication or excessive load | Ensure proper lubrication and reduce the load |
| Electrical faults | Motor or electrical connection issues | Check motor and electrical connections |
