Worm Reducer-Replacement of Fenner FV Type Worm Gearbox FV800

Our company provides Fenner brand replacement worm gearboxes, which are high quality and offered at competitive prices. Please note that our products are replacement parts and not original equipment manufacturer (OEM) parts. If you require OEM parts, please contact the original supplier for purchase.

Product Features

• The housing is made of high-quality FG-260 grade C.I. for durability.
• The gearbox is equipped with well-designed cooling fins and a suitable fan to dissipate heat effectively.
• The entire design is based on BS 721:1963 with precision 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 for enhanced performance.
• The worm wheel is made of high-quality phosphor bronze, with a substantial cross-section for rigid coupling with the hub.
• Both the worm shaft and worm wheel shaft are mounted on high-quality tapered roller/angular contact bearings to withstand axial thrust and overhung loads.
• With a maximum temperature limit of 90??C under full load, the minimum gear life for all gearboxes is 20,000 hours. The gearboxes require no maintenance apart from checking the oil level every two weeks.
• All worm gearboxes have transmission ratios ranging from 5:1 to 70:1.

Choosing the Right Worm Gearbox

The selection of a 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. To handle similar problems, it is necessary to consider the use coefficient to achieve equivalent load or design power. Therefore, equivalent load = actual load x service factor mechanical rated value, and the capacity is measured in terms of life and/or strength under uniform load conditions running continuously for 10 hours per day. If the equipment runs more than 10 hours per day, the mechanical service factor should be chosen based on the prime mover type, daily operating hours, and the application type and its load characteristics connected to the equipment to ensure appropriate gear life. The catalog rated value of the selected equipment should be at least equal to or greater than half of the maximum overload achieved during its operation. By comparing the actual transmission load with the catalog rated value, the gearboxes' service life can be determined.

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

Possible Issues and Solutions

Installation Considerations

The gearbox should be securely mounted to minimize the impact of vibration 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/tyre couplings) is crucial to improve gearbox performance. The couplings should be
