Product Overview

The Worm Reducer features the following characteristics:

• The housing is made of high-quality FG-260 grade C.I. for durability.
• The gearbox is equipped with well-designed heat sinks and suitable fans to efficiently dissipate heat.
• The entire design is based on BS 721:1963 with a precision grade of A.
• The gearbox is designed to be interchangeable with standard gearboxes.
• The worm shaft is made of high-quality hardened steel for precise generation and grinding, resulting in improved performance.
• The worm wheel is made of extremely high-quality phosphor bronze, with a large cross-section for enhanced rigidity when combined with the hub.
• Both the worm shaft and the worm wheel shaft are mounted on high-quality tapered roller/angular contact bearings to withstand axial thrust and radial loads.
• With a maximum temperature limit of 90 degrees Celsius under full load conditions, all gearboxes have a minimum gear life of 20,000 hours.
• No maintenance is required for the gearbox, just check 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 suitable gearbox is based on comparing the actual transmission load with the catalog rating values. However, the actual load conditions may vary or fluctuate depending on the application type. To handle similar conditions, it is necessary to consider the use factor to achieve an equivalent load or design power. Therefore, the equivalent load = actual load x service factor mechanical rating 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, it is necessary to select a service factor based on the type of prime mover, the number of operating hours per day, the application type of the equipment connected to it, and its load characteristics to ensure the appropriate gear life. The catalog rating value of the selected equipment should be at least equal to or greater than half of the maximum overload achieved during its operation. The lifespan of the gearbox can be determined by comparing the actual transmission load with the catalog rating value. Follow these steps:

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.

Structure of Worm Reducer

The Worm Reducer consists of the following components:

• Worm shaft: It is responsible for transmitting power and has a high-quality hardened surface for improved performance.
• Worm wheel: It is made of high-quality phosphor bronze and has a large cross-section for enhanced rigidity.
• Housing: It is made of fine FG-260 grade C.I. for durability.
• Heat sinks and fans: They efficiently dissipate heat generated during operation.
• Tapered roller/angular contact bearings: They support the worm shaft and worm wheel shaft to withstand axial thrust and radial loads.

When using this type of Worm Reducer, you may encounter certain issues, their causes, and the corresponding solutions:

Proper installation of the gearbox is crucial to minimize fluctuations or heavy loads. Ensure proper alignment and use dowel pins to correctly position the gears, preferably in a diagonal direction. The use of flexible couplings (gear couplings with rubber bushing or tire couplings) is essential to enhance gearbox performance. Align the couplings to avoid angular and eccentric misalignment.

Electric Motors for Worm Gear Reducers

Electric motors play a vital role in the operation of Worm Gear Reducers. They provide the necessary power and drive for the gearbox to function effectively. At our company, we also offer a wide range of electric motors for sale to complement our Worm Gear Reducers.
