Product Features
Body Structure
The shell of the gearbox is made of high-quality FG-260 grade C.I. The gearbox is equipped with well-designed cooling fins and a suitable fan to effectively dissipate heat. The entire design is based on BS 721:1963, with an accuracy rating of A. The gearbox is designed to be interchangeable with standard gearboxes.
Worm Shaft and Worm Wheel
The worm shaft is made of high-quality surface-hardened steel, which is very precisely generated and ground for better performance. The worm wheel is made of extremely high-quality phosphor bronze, with a large cross-section (combined with hub rigidity). The worm shaft and worm wheel are installed on high-quality tapered roller/angular contact bearings to withstand axial thrust and suspended loads.
Gearbox Maintenance
No maintenance is required for the gearbox. Check the oil level once every two weeks.
Transmission Ratio
The transmission ratio of all worm gearboxes ranges from 5:1 to 70:1.
Product Structure
The worm reducer consists of the following parts:
- Worm shaft
- Worm wheel
- Gearbox housing
- Coupling
- Bearing
- Oil seal
- Output shaft
- Output flange
- Bolt
The worm shaft and worm wheel are the key components of the worm reducer, responsible for transmitting the power. The gearbox housing provides a protective casing for the worm shaft and worm wheel. The coupling connects the gearbox to the motor. The bearing supports the shaft and reduces friction. The oil seal prevents lubricant leakage. The output shaft and output flange are used to connect the gearbox to other equipment.
Selection of Suitable Worm Gearbox
The selection of suitable worm gearboxes is done by comparing the actual transmission load with the catalog rated value. However, actual load conditions may vary or fluctuate depending on the application type, and in order to deal with the same problem, it is necessary to consider the use coefficient to achieve equivalent load or design power. Therefore, the equivalent load = actual load x use coefficient. Mechanical rated value and service coefficient mechanical rated value are used to measure capacity, assuming continuous operation for 10 hours per day under uniform load conditions. If the equipment operates more than 10 hours per day, the mechanical service coefficient should be selected based on the type of prime mover, the number of hours of operation per day, and the application type and load characteristics of the equipment connected to it to ensure proper gear life. The catalog rated value of the selected equipment should be at least equal to or greater than half of the maximum overload reached during its operation. By comparing the actual transmission load with the catalog rated value, the service life of the gearbox can be determined. The steps are as follows:
- Calculate the required ratio
- Calculate the design power based on the load type, working time, and service coefficient
- Calculate the output torque
- Select the device based on the data
Possible Issues with Worm Gearbox and Solutions
| Problem | Cause | Solution |
|---|---|---|
| Overheating of gearbox | Excessive friction, insufficient cooling | Improve lubrication, enhance cooling |
| Noise of gearbox | Worm wheel or worm shaft wear, improper meshing | Replace worn parts, adjust meshing |
| Vibration | Loose parts, bearing wear | Tighten screws, replace bearings |
| Oil leakage | Sealing failure | Replace seal |
| Non-working gearbox | Motor failure, electrical failure | Check and repair motor and electrical system |
| Abnormal noise of gearbox | Foreign object intrusion, gear damage | Clean, inspect and replace gears if necessary |
| Excessive load on gearbox | Excessive transmission load, design failure of gearbox | Reduce transmission load, replace gearbox if necessary |
| Worm shaft wear | Poor lubrication, long-term overload | Improve lubrication, reduce load |

Installation Notes for Gearbox
The gearbox should be securely installed to minimize the impact of vibration or heavy loads. Make sure it is properly aligned and use dowels to position the gears in the appropriate position, preferably in a diagonal direction. The use of flexible couplings (gear coupling flanges/tire couplings with rubber liners) is important for improving gearbox performance. The couplings should be aligned to avoid angular and eccentric misalignment.
Motors for Worm Gear Reducers
The worm gear reducer and electric motor are closely related and interdependent. The worm gear reducer relies on the electric motor for power, while the electric motor relies on the worm gear reducer for speed reduction and torque increase. Our company provides a wide variety of electric motors for use with our worm gear reducers. Our electric motors are of high quality and reasonably priced.
