Product Features

• The housing is made of high-density FG-260 cast iron
• The gearbox is equipped with well-designed heat dissipation fins and suitable fans
• The entire design is based on BS 721:1963 with accuracy grade A
• The gearbox is designed to be interchangeable with standard gearboxes
• The worm shaft is made of high-quality surface-hardened steel, precisely generated and ground
• The worm wheel is made of high-quality phosphor bronze, with a large cross-section for enhanced rigidity
• The worm shaft and worm wheel shaft are mounted on high-quality tapered roller/angular contact bearings to withstand axial thrust and radial loads
• The minimum gear life of all gearboxes is 20,000 hours under full load and 90??C temperature limitation
• No maintenance is required for the gearbox, only check the oil level every two weeks
• All worm gearboxes have a transmission ratio ranging from 5:1 to 70:1

Structure of the Worm Reducer

The Worm Reducer consists of the following components:

1. Worm shaft
2. Worm wheel
3. Housing
4. Heat dissipation fins
5. Fans
6. Bearings

Selection of Suitable Worm Gearbox

The selection of the worm gearbox is done by comparing the actual transmission load with the catalog rated values. However, actual load conditions may vary or fluctuate depending on the application type, and equivalent loads or design powers must be considered to handle the same problem. Therefore, the equivalent load = actual load x service factor x mechanical rated value. The capacity is measured in terms of life and/or strength, assuming continuous operation for 10 hours per day under uniform load conditions. If the equipment operates for more than 10 hours per day, the mechanical service factor should be selected based on the type of prime mover, number of hours of operation per day, application type to which the equipment is connected, and its load characteristics 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. The gearbox's service life can be determined by comparing the actual transmission load with the catalog rated values. Follow these steps:

1. Calculate the required ratio
2. Calculate the design power based on load type and working hours
3. Calculate the output torque
4. Select the appropriate device based on the data

Installation Considerations

It is important to securely install the gearbox to minimize the impact of vibrations or heavy loads. Ensure proper alignment and use dowel pins to position the gears correctly, preferably in a diagonal direction. The use of flexible couplings (gear couplings with rubber inserts / tire couplings) is crucial for improving the performance of the gearbox. The couplings should be aligned to avoid angular and eccentric misalignment.
