Worm Reducer-Replacement of Fenner FU Type Worm Gearbox FU500

Introduction

The Worm Reducer-Replacement of Fenner FU Type Worm Gearbox FU500 is a high-quality replacement product offered by our company. It is designed to replace the Fenner brand worm gearbox, providing excellent quality and competitive prices. Please note that our products are replacement parts and not original equipment. For original equipment purchases, please contact the original supplier.

Product Features

• The casing is made of fine FG-260 grade C.I., ensuring durability and reliability.
• The gearbox is equipped with well-designed cooling fins and an appropriate fan to dissipate heat effectively.
• The entire design is based on BS 721:1963 standards, with a precision rating of 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 optimal performance.
• The worm wheel is made of high-quality phosphor bronze, using sandwich casting/centrifugal casting with a large cross-section for enhanced rigidity.
• Both the worm shaft and worm wheel are mounted on high-quality tapered roller/angular contact bearings to withstand axial thrust and radial loads.
• With a temperature limit of 90 degrees Celsius, the minimum gear life of all gearboxes under full load is 20,000 hours. The gearboxes require minimal maintenance, with a recommended oil level check every two weeks.
• All worm gearboxes have a transmission ratio ranging from 5:1 to 70:1.

Structure of Worm Reducer

The Worm Reducer consists of the following components:

• Worm Shaft: The main driving component that transmits power.
• Worm Wheel: The driven component that engages with the worm shaft.
• Housing: The casing that houses and protects the worm shaft and worm wheel.
• Bearings: The bearings that support the worm shaft and worm wheel, allowing smooth rotation.
• Seals: The seals that prevent leakage of lubricating oil and protect the internal components.
• Gears: The gears that transmit power from the worm shaft to the worm wheel.

Selection of Suitable Worm Gearbox

The selection of a worm gearbox is determined by comparing the actual transmission load with the catalog-rated values. However, the 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, the equivalent load = actual load x service coefficient, mechanical rated values, and service coefficient mechanical rated values are used to measure capacity 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 coefficient should be selected based on the type of prime mover, number of hours of operation per day, application type connected to the equipment, and its load characteristics to ensure adequate 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 service life of the gearbox can be determined by comparing the actual transmission load with the catalog-rated values using the following steps:

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

Installation Considerations

When installing the worm gearbox, it is important to follow these considerations:

• Secure installation to minimize vibrations or excessive loads.
• Ensure proper alignment by using dowel pins to position the gears correctly, preferably in a diagonal direction.
• Using flexible couplings (gear couplings/fluid couplings with rubber inserts) is crucial to improve the performance of the worm gearbox. Align the couplings to avoid angular or eccentric misalignment.
