The SNU-U Worm Gear Unit is a part of the Worm Reducer-Replacement of Elecon SNU Modular Universal Mounting series. It is known for its wide ribs, which increase the heat dissipation area. The streamlined oil sump can hold more oil, and the larger fan increases the thermal rating of the gearbox. These features result in increased continuous load capacity without a significant rise in temperature. The gearbox can be easily replaced by moving the fan and fan cover from one end of the worm shaft to the other, eliminating the need to open the gearbox manually. Our company offers Elecon-branded replacement worm gearboxes that are of high quality and competitively priced. It is important to note that our products are only replacement parts for the original equipment and not original manufacturer parts. If you need to purchase original manufacturer parts, please contact the original supplier. 
The gearbox casing is designed with a streamlined shape and made of strong fine-grain cast iron. It is fully oil and dust-proof, allowing for outdoor installation without the need for separate covers. The surface and bores are precisely drilled and machined using the latest precision machinery to ensure perfect alignment and interchangeability.
The worm is made of carburized alloy steel that has been ground and polished, and it is integrated with the shaft. The bearing journals of the shaft are precisely ground. The worm wheel is made of phosphor bronze wheel rims cast centrifugally. The worm is machined on a dedicated worm milling machine and undergoes gas carburizing and grinding on an automated workpiece grinder. The worm wheel is hobbed with high precision gear cutters on a precision gear hobbing machine. Each worm wheel is inspected and matched with the main worm to ensure complete interchangeability.
The worm and worm wheel are supported by ball or roller anti-friction bearings, which provide sufficient safety margin to withstand the required shaft and thrust loads. Cantilever loads generated by chain or small gears are generally permissible as the gearbox and bearings are designed for this purpose. However, complete detailed information should be provided to confirm. In cases where the cantilever load is heavy, additional roller bearings can be provided.
The shaft is made of high-strength carbon steel. With its large diameter, it can withstand torsional and bending loads caused by cantilever drives. 
The single-piece universal housing has top and bottom flanges, as well as support flanges, allowing the gearbox to be installed in various positions such as low speed, high speed, and vertical. Hence, the internal components are interchangeable for all installation positions. Simply invert the device and change the positions of the drain plug, breather plug, and oil level indicator to quickly switch the installation position from low speed to high speed and vice versa. The robust and compact streamlined design provides ample heat capacity. 
| Problem | Cause | Solution |
|---|---|---|
| Excessive noise | Worn gears or improper lubrication | Inspect and replace worn gears, and ensure proper lubrication |
| Overheating | Insufficient cooling or excessive load | Check cooling system and reduce load if necessary |
| Leakage of oil | Damaged seals or loose fittings | Replace damaged seals and tighten fittings |
| Abnormal vibration | Imbalanced gears or misalignment | Balance gears and ensure proper alignment |
| Shaft breakage | Excessive torque or material defects | Reduce torque and inspect for material defects |
