Product Description
Note recommendations
To install the reduction unit it is necessary tonote the following recommendations:
1. Check the correct direction of rotation of thereduction unit output shaft before fitting the unit tothe machine.
2. Before mount with the prime moveanddevice,please check the reducers every axiadiameter, aperture,key and key slot,
to be theirdimensions are not deviation, and avoidassembaurtoo tight or too loose, unless it wilinfluence the reducer’s performance.
3. The mounting on the machine must be stableto avoid anv vibration.
4.Whenever possible,protect the reductiorunit against solar radiation and bad weather.
5.In the case of particularly lengthy periods ofstorage (4-6 months), if the oil seal is not immersedin the lubricant inside the unit.
It is recommended tochange it since the rubber could stick to the shaft ormay even have lost the elasticity it needs to functionproperly.
6.Painting must definitely not go over rubberparts and the holes on the breather plugs, if any.
7.When connect with hollow or CHINAMFG shaftplease grease the joint to avoid lock or oxidation.
8.Check the correct level of the lubricantthrough the indicator, if there is one.
9. Starting must take place gradually, withoutimmediately applying the maximum load
10. Supporting unit is required when usingvarious of reducer matched with motor directiy andthe wsight of motor is a little bigger than common.
11 .Ensure the motor cools correctly byassuring good passage of air from the fan side.
12. In the case of ambient temperatures+40°C call the Technical Service. /* January 22, 2571 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(“,”).forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1

Can a Worm Gearbox be Used for High-Speed Applications?
Worm gearboxes are generally not recommended for high-speed applications due to their inherent design characteristics. Here’s why:
- Efficiency: Worm gearboxes tend to have lower efficiency compared to other gearbox types, which means they can generate more heat and experience more energy loss at high speeds.
- Heat Generation: The sliding contact between the worm and worm wheel in a worm gearbox can lead to significant friction and heat generation, especially at high speeds. This heat can cause thermal expansion, affecting the gearbox’s performance and longevity.
- Wear and Noise: High speeds can exacerbate wear and noise issues in worm gearboxes. Increased friction and wear can lead to faster degradation of components, resulting in reduced lifespan and increased maintenance needs.
- Backlash: Worm gearboxes may have higher backlash compared to other gearbox types, which can impact precision and accuracy in high-speed applications.
While worm gearboxes are more commonly used in applications requiring high torque and moderate speeds, they may not be the best choice for high-speed scenarios. If high-speed operation is a requirement, other gearbox types such as helical, spur, or planetary gearboxes are often better suited due to their higher efficiency, lower heat generation, and reduced wear at elevated speeds.
Worm Gearbox vs. Helical Gearbox: A Comparison
Worm gearboxes and helical gearboxes are two popular types of gear systems, each with its own set of advantages and disadvantages. Let’s compare them:
| Aspect | Worm Gearbox | Helical Gearbox |
| Efficiency | Lower efficiency due to sliding friction between the worm and worm wheel. | Higher efficiency due to rolling contact between helical gear teeth. |
| Torque Transmission | Excellent torque transmission and high reduction ratios achievable in a single stage. | Good torque transmission, but may require multiple stages for high reduction ratios. |
| Noise and Vibration | Generally higher noise and vibration levels due to sliding action. | Lower noise and vibration levels due to smoother rolling contact. |
| Backlash | Higher inherent backlash due to the design. | Lower backlash due to meshing of helical teeth. |
| Efficiency at Higher Speeds | Less suitable for high-speed applications due to efficiency loss. | More suitable for high-speed applications due to higher efficiency. |
| Overload Protection | Natural self-locking feature provides some overload protection. | May not have the same level of inherent overload protection. |
| Applications | Commonly used for applications requiring high reduction ratios, such as conveyor systems and heavy-duty machinery. | Widely used in various applications including automotive transmissions, industrial machinery, and more. |
Both worm and helical gearboxes have their place in engineering, and the choice between them depends on the specific requirements of the application. Worm gearboxes are preferred for applications with high reduction ratios, while helical gearboxes are chosen for their higher efficiency and smoother operation.
Lubrication Requirements for a Worm Gearbox
Lubrication is crucial for maintaining the performance and longevity of a worm gearbox. Here are the key considerations for lubricating a worm gearbox:
- Type of Lubricant: Use a high-quality, high-viscosity lubricant specifically designed for worm gearboxes. Worm gearboxes require lubricants with additives that provide proper lubrication and prevent wear.
- Lubrication Interval: Follow the manufacturer’s recommendations for lubrication intervals. Regularly check the gearbox’s temperature and oil condition to determine the optimal frequency of lubrication.
- Oil Level: Maintain the proper oil level to ensure effective lubrication. Too little oil can lead to insufficient lubrication, while too much oil can cause overheating and foaming.
- Lubrication Points: Identify all the lubrication points on the gearbox, including the worm and wheel gear surfaces. Apply the lubricant evenly to ensure complete coverage.
- Temperature: Consider the operating temperature of the gearbox. Some lubricants have temperature limits, and extreme temperatures can affect lubricant viscosity and performance.
- Cleanliness: Keep the gearbox and the surrounding area clean to prevent contaminants from entering the lubricant. Use proper filtration and seals to maintain a clean environment.
- Monitoring: Regularly monitor the gearbox’s temperature, noise level, and vibration to detect any signs of inadequate lubrication or other issues.
Proper lubrication will reduce friction, wear, and heat generation, ensuring smooth and efficient operation of the worm gearbox. Always refer to the manufacturer’s guidelines for lubrication specifications and intervals.
