Features

• The casing is made of FG-260 grade C.I.
• The gearbox is equipped with well-designed fins and a suitable fan that can fully dissipate the heat generated.
• The entire design is based on BS 721:1963 with an accuracy level of A.
• The gearbox is designed to be interchangeable with standard gearboxes.
• The worm shaft is made of high-quality surface-hardened steel and is very precisely generated and ground for better performance.
• The worm wheel is made of extremely high-quality phosphor bronze, which is casted/ spun and has a very large cross-section (combining with the hub rigidity).
• The worm shaft and worm wheel shaft are both mounted on high-quality tapered roller/ angular contact bearings to withstand axial thrust and suspended loads.
• The minimum gear life of all gearboxes is 20,000 hours under full load with a temperature limit of 90 degrees Celsius.
• The gearbox requires no additional maintenance and only needs to be checked for oil level every two weeks.
• The transmission ratio of all worm gearboxes is from 5:1 to 70:1.

Structure of Worm Reducer

The Worm Reducer consists of the following parts:

• Worm wheel
• Worm shaft
• Housing
• Oil seal
• Bearing
• Input shaft
• Output shaft

The worm wheel and worm shaft are the key components in the Worm Reducer, responsible for the power transmission and gear reduction. The housing provides support and protection for the internal components. The oil seal prevents lubricant from leaking out of the housing and dirt from getting inside. The bearing supports the input and output shafts and acts as a load-bearing component.

Choosing the Right Worm Gearbox

The selection of the gearbox is completed 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 handle the same problem, a utilization factor must be considered to achieve equivalent load or design power. Therefore, the equivalent load = actual load x utilization factor.

Capacity is measured by mechanical rated value and service factor mechanical rated value for life and/or strength under uniform load conditions assuming continuous operation for 10 hours a day. If the equipment operates for more than 10 hours a day, the mechanical service factor should be selected based on the original motor type, hours of operation per day, and the type of application and its load characteristics connected to the equipment to ensure the appropriate gear life catalog rated values allow for momentary 100% overload during start-up, braking or operation and up to 10 times a day. Therefore, 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.

The gearbox's service life can be determined by comparing the actual transmission load with the catalog rated value. The following steps are involved:

1. Calculate the required ratio.
2. Calculate the design power by load type, operating time, and service factor.
3. Calculate the output torque.
4. Select the device based on the data.

Troubleshooting

Problem	Cause	Solution
Gearbox overheat	Insufficient lubrication or excessive load	Increase lubrication or reduce the load
Gearbox noise	Misaligned gears or worn bearings	Realign gears or replace bearings
Vibration	Misaligned gears or rotor imbalance	Realign gears or balance the rotor
Oil leakage	Damaged oil seal or cracked housing	Replace oil seal or housing
Gearbox not working	Power failure or broken input shaft	Check power supply or replace input shaft
Excessive backlash	Worn gears or incorrect gear installation	Replace gears or reinstall correctly
Gearbox seizing	Insufficient lubrication or excessive load	Increase lubrication or reduce the load
Gear wear	Insufficient lubrication or excessive load	Increase lubrication or reduce the load
