Worm Reducer-Replacement of Fenner FU Type Worm Gearbox FU237
Our company provides a replacement for the Fenner FU Type Worm Gearbox, known as Worm Reducer. Our products are of high quality and are offered at a reasonable price. We provide replacement parts for original factory parts. If you need to purchase original factory parts, please contact the original supplier for purchase.
Product Overview
Worm Reducer is a replacement for the Fenner FU Type Worm Gearbox (FU237). It has the following features:
- The housing is made of high-quality FG-260 C.I. material.
- The gearbox is equipped with well-designed cooling fins and a suitable fan to dissipate heat.
- 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, which is very precise and ground for better performance.
- The worm gear is made of high-quality phosphor bronze, which is cast in layers and has a large cross-section (combined with the hub rigidity).
- The worm shaft and worm gear are both mounted on high-quality tapered roller/angular contact bearings to withstand axial thrust and suspended loads.
- The minimum gear life for all gearboxes at full load is 20,000 hours, limited by a temperature of 90 degrees Celsius.
- The gearbox requires no 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.

Component Structure
The Worm Reducer consists of the following parts:
- Worm shaft
- Worm gear
- Housing
- Bearing
- Oil seal
- Output shaft
The worm shaft is responsible for generating power. The worm gear meshes with the worm shaft and transmits power to the output shaft. The housing provides protection for the internal components. The bearing supports the worm shaft and worm gear. The oil seal prevents oil leakage. The output shaft is where the power is transferred to the driven machine.

Choosing the Appropriate Worm Gearbox
Selecting the right gearbox is done by comparing the actual transmission load to the catalog rating. However, actual load conditions may vary or fluctuate depending on the application type, and equivalent load or design power must be considered to handle the same problem. Therefore, the equivalent load = actual load x service factor mechanical rating and service factor mechanical rating is used to measure capacity in terms of life and/or strength, assuming 10 hours of continuous operation per day under uniform load conditions. If the equipment operates more than 10 hours a day, the mechanical service factor should be selected based on the type of prime mover, number of hours of operation per day, and the application type and its load characteristics, to ensure an appropriate gear life. The catalog rating 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 rating, the gearbox's operating life can be determined.
- Calculate the required ratio.
- Calculate the design power by load type, working time, and service factor.
- Calculate the output torque.
- Select the device based on the data.

Possible Issues and Solutions

Q&A
- What is the minimum gear life for all gearboxes at full load?
- What are the parts of the Worm Reducer?
- What should I do if my gearbox overheats?
The minimum gear life for all gearboxes at full load is 20,000 hours, limited by a temperature of 90 degrees Celsius.
The Worm Reducer consists of the worm shaft, worm gear, housing, bearing, oil seal, and output shaft.
If your gearbox overheats, you should reduce the load or improve lubrication.
