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.

Calculating Gear Ratio in a Worm Reducer
The gear ratio in a worm reducer is determined by the number of teeth on the worm wheel (also known as the worm gear) and the number of threads on the worm shaft. The gear ratio formula for a worm reducer is:
Gear Ratio = Number of Teeth on Worm Wheel / Number of Threads on Worm Shaft
For example, if the worm wheel has 60 teeth and the worm shaft has a single thread, the gear ratio would be 60:1.
It’s important to note that worm reducers have an inherent self-locking property due to the angle of the worm threads. As a result, the gear ratio also affects the mechanical advantage and the system’s ability to resist backdriving.
When calculating the gear ratio, ensure that the worm reducer is properly designed and that the gear ratio aligns with the desired mechanical characteristics for your application. Additionally, consider factors such as efficiency, load capacity, and speed limitations when selecting a gear ratio for a worm reducer.
How to Calculate the Efficiency of a Worm Gearbox
Calculating the efficiency of a worm gearbox involves determining the ratio of output power to input power. Efficiency is a measure of how well the gearbox converts input power into useful output power without losses. Here’s how to calculate it:
- Step 1: Measure Input Power: Measure the input power (Pin) using a power meter or other suitable measuring equipment.
- Step 2: Measure Output Power: Measure the output power (Pout) that the gearbox is delivering to the load.
- Step 3: Calculate Efficiency: Calculate the efficiency (η) using the formula: Efficiency (η) = (Output Power / Input Power) * 100%
For example, if the input power is 1000 watts and the output power is 850 watts, the efficiency would be (850 / 1000) * 100% = 85%.
It’s important to note that efficiencies can vary based on factors such as gear design, lubrication, wear, and load conditions. The calculated efficiency provides insight into how effectively the gearbox is converting power, but it’s always a good practice to refer to manufacturer specifications for gearbox efficiency ratings.
Preventing Backlash in a Worm Gearbox
Backlash in a worm gearbox can lead to reduced accuracy, positioning errors, and decreased overall efficiency. Here are steps to prevent or minimize backlash:
- High-Quality Components: Use high-quality worm gears and worm wheels with tight manufacturing tolerances. Precision components will help reduce backlash.
- Proper Meshing: Ensure the worm gear and worm wheel are properly aligned and meshed. Improper meshing can lead to increased backlash.
- Preload: Applying a small amount of preload to the worm gear can help reduce backlash. However, excessive preload can increase friction and wear.
- Anti-Backlash Mechanisms: Consider using anti-backlash mechanisms, such as spring-loaded systems or adjustable shims, to compensate for any inherent backlash.
- Lubrication: Proper lubrication can reduce friction and play a role in minimizing backlash. Use a lubricant that provides good film strength and reduces wear.
- Maintenance: Regularly inspect and maintain the gearbox to identify and address any changes in backlash over time.
It’s important to strike a balance between reducing backlash and maintaining smooth operation. Consulting with gearbox experts and following manufacturer guidelines will help you optimize your worm gearbox’s performance while minimizing backlash.
