Worm Reducer-Replacement of Fenner FU Type Worm Gearbox FU1000

Our company provides the Fenner brand replacement of worm gearbox FU type, which has good quality and competitive prices. Our products are only replacement parts for the original factory parts, and if you need to buy original factory parts, please contact the original supplier. The worm reducer has the following features:

• The housing is made of fine FG-260 grade C.I.
• The gearbox is equipped with well-designed heat dissipation fins and appropriate fans to fully dissipate the generated heat.
• The entire design is based on BS 721:1963, with an accuracy class 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 accurately generated and ground for better performance.
• The worm wheel is made of extremely high-quality phosphor bronze, sandwich cast/spun, and has a fairly large cross-section (combined with hub rigidity).
• The worm shaft and worm wheel shaft are both mounted on high-quality tapered roller/angle contact bearings to withstand axial thrust and suspended loads.
• Under a loaded condition of 90 degrees Celsius, the minimum gear life of all gearboxes is 20,000 hours. The gearbox requires no maintenance, just check the oil level every two weeks.
• The transmission ratio of all worm gearboxes is from 5:1 to 70:1.

Composition and structure of worm reducer

The worm reducer is composed of the following parts:

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

Each part has its own function, as follows:

Part	Function
Worm	Drives the worm wheel to achieve the desired speed reduction ratio.
Worm wheel	Meshes with the worm and transmits power to the output shaft.
Housing	Supports and protects the worm and worm wheel, as well as other internal parts.
Bearing	Supports the input and output shafts and maintains their relative position.
Oil seal	Prevents lubricant leakage and prevents dirt and other contaminants from entering the gearbox.
Output shaft	Transmits power to the load.
Input shaft	Receives power from the motor or other power source.
Coupling	Connects the input and output shafts and compensates for misalignment.

Choosing the appropriate Worm Gearbox

The selection of gearbox is done by comparing the actual transmission load with the catalog rated value. However, the actual load conditions may vary or fluctuate depending on the type of application, and to handle the same problem, it is necessary to consider using a factor to achieve equivalent load or design power. Therefore, equivalent load = actual load x service factor mechanical rated value and 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 more than 10 hours per day, the mechanical service factor should be selected based on the type of prime mover, the number of hours per day of operation, and the load characteristics of the application to which the equipment is connected to ensure an appropriate gear life catalog rated value allows for an instantaneous 100% overload during start-up, braking, or operation up to 10 times a day at most. Therefore, 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 period. The service life of the gearbox can be determined by comparing the actual transmission load with the catalog rated value through the following steps:

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

Possible Problems and Solutions

The following table lists the problems that may occur when using this type of worm reducer, as well as the causes and solutions for each problem:

Problem	Cause	Solution
Overheating of gearbox	Overloaded gearbox, insufficient lubrication, or poor ventilation	Reduce the load or increase the gearbox size, improve the lubrication system, or improve the ventilation system
Noise from gearbox	Loose parts, worn gears or bearings, or poor meshing between gears	Tighten the loose parts, replace the worn gears or bearings, or improve the meshing between gears
Vibration	Loose parts, misaligned shafts, or unbalanced loads	Tighten the loose parts, align the shafts, or balance the loads
Oil leakage	Worn seals or gaskets, or loose bolts	Replace the worn seals or gaskets, or tighten the loose bolts
Gearbox not working	Electrical or mechanical failure, or blocked input or output shafts	Check the electrical or mechanical system, or remove the blockage
Low efficiency	Low quality lubricant, or worn gears or bearings	Use high-quality lubricant, or replace the worn gears or bearings
Short life	Overloaded gearbox, low quality lubricant, or poor maintenance	Reduce the load, use high-quality lubricant, or improve the maintenance
Shaft breakage	Overloaded gearbox, or misaligned shafts	Reduce the load, or align the shafts

Electric Motors for Worm Gear Reducers

The worm reducer and electric motor are complementary to each other. The worm reducer provides speed reduction and torque multiplication, while the electric motor provides power to the worm reducer. Therefore, the selection of the electric motor should be based on the required power and speed of the worm reducer. Our company also provides various types of electric motors for sale, so customers can choose the most suitable electric motor according to their needs.We are a comprehensive transmission equipment manufacturer integrating research and development, manufacturing, and sales of speed reducers. With more than 20 years of experience in the industry, we serve customers in Europe, America, Africa, Asia, and other regions, and have won the praise of the market. Our company has introduced advanced production equipment and testing equipment at home and abroad, and employs industry professionals and technicians to carry out innovative research and development and manufacturing, using standardized production management methods to strictly control every aspect of the production of reducers. Our gearboxes are widely used in the equipment industry, food industry, car washing industry, packaging industry, transmission industry, automation industry, solar energy industry, and more. We encourage customers to explore our products and contact us to make a purchase.

Q&A:

1. • Q: Can I use the worm reducer in a high-temperature environment?

A: The worm reducer has a loaded condition temperature limit of 90 degrees Celsius. If the actual temperature exceeds this limit, the gearbox may overheat, reduce efficiency, and have a shorter lifespan.

1. • Q: Can I use the worm reducer in a high-speed application?

A: The worm reducer has a transmission ratio of 5:1 to 70:1, which is suitable for low-speed and high-torque applications. If the required speed is higher than the rated speed of the worm reducer, it may cause vibration, noise, and other problems.

1. • Q: How often should I check the oil level of the gearbox?

A: The gearbox requires no maintenance, except to check the oil level every two weeks. If the oil level is too low, it may cause the gearbox to overheat and reduce efficiency.
