Can I Use Synthetic Oil in My Gearbox?
Yes, you can use synthetic oil in your gearbox, and in many cases, it can offer several advantages over conventional mineral-based oils:
- Improved Temperature Stability: Synthetic oils typically have a higher resistance to thermal breakdown, making them suitable for gearboxes that operate at high temperatures.
- Enhanced Lubrication: Synthetic oils often have superior lubrication properties, providing better protection against friction, wear, and component damage.
- Extended Oil Change Intervals: Synthetic oils can often withstand longer operating periods without losing their effectiveness, reducing the frequency of oil changes and maintenance.
- Reduced Viscosity Changes: Synthetic oils are less prone to viscosity changes at different temperatures, ensuring consistent lubrication performance in varying conditions.
- Lower Friction and Energy Loss: The smoother molecular structure of synthetic oils can lead to reduced internal friction, potentially improving gearbox efficiency and performance.
- Cold Weather Performance: Synthetic oils generally flow better at low temperatures, making them suitable for gearboxes operating in cold climates.
- Protection Against Oxidation: Synthetic oils often have better resistance to oxidation, helping to prevent the formation of sludge and deposits that can impact gearbox performance.
However, before switching to synthetic oil, it’s important to consider the manufacturer’s recommendations and specifications for your specific gearbox model. Some gearboxes may have specific requirements or restrictions on the type of lubricant to use. If the manufacturer approves the use of synthetic oil, it can be a beneficial choice, but if not, sticking to the recommended oil type is crucial to ensure proper gearbox function and warranty coverage.

What is a Gearbox and How Does It Work?
A gearbox is a mechanical device that transmits power and changes the speed or torque of a rotating input shaft to a different output shaft. It is commonly used in various machines and equipment to control the speed and direction of motion.
Here’s how a gearbox works:
- Input Shaft: The gearbox receives rotational energy from an input shaft connected to a power source, such as an electric motor or an engine.
- Gears: Inside the gearbox are a set of gears with different sizes. These gears mesh with each other, and their arrangement determines the gear ratio, which defines how many revolutions the output shaft will make for a given rotation of the input shaft.
- Output Shaft: The output shaft is connected to the machinery or equipment that needs to be powered. As the gears rotate, the motion and power are transmitted from the input shaft to the output shaft.
- Gear Ratio: By selecting different gear combinations, the gearbox can change the speed and torque of the output shaft. A higher gear ratio results in higher torque and lower speed, while a lower gear ratio provides higher speed and lower torque.
Gearboxes play a crucial role in various applications, including automobiles, industrial machinery, robotics, and more, enabling efficient power transmission and speed control.

Importance of Lubrication in Gearbox Performance
Lubrication plays a critical role in ensuring the optimal performance, longevity, and reliability of gearboxes. Proper lubrication provides several key benefits:
- Reduces Friction and Wear: Lubrication forms a protective layer between gear teeth, bearings, and other moving components, reducing friction and minimizing wear and tear.
- Heat Dissipation: Lubricants help dissipate the heat generated during gear operation, preventing overheating and potential damage to components.
- Noise Reduction: Adequate lubrication can dampen noise and vibration produced by gear meshing, leading to quieter and smoother operation.
- Sealing and Contaminant Prevention: Lubricants create a barrier that seals out contaminants like dust, dirt, and moisture, preventing their entry and reducing the risk of corrosion and damage.
- Enhanced Efficiency: Proper lubrication reduces energy losses due to friction, improving the overall efficiency of the gearbox.
- Extended Lifespan: Lubrication helps prevent premature component wear and failure, extending the lifespan of the gearbox and minimizing the need for costly repairs or replacements.
- Optimal Performance: Gearboxes operate within specified tolerances when properly lubricated, ensuring they deliver the intended performance and functionality.
It’s essential to use the recommended lubricant type, viscosity, and change intervals specified by the gearbox manufacturer to ensure the best possible performance and longevity. Regular monitoring and maintenance of lubrication levels are crucial to preserving the health of the gearbox and its components.

How to Calculate Gear Ratio in a Gearbox
Gear ratio is a fundamental parameter in a gearbox that represents the ratio of the number of teeth between two gears. It determines how much the output gear rotates in relation to the input gear. The formula to calculate gear ratio is:
Gear Ratio (GR) = Number of Teeth on Output Gear / Number of Teeth on Input Gear
Here’s a step-by-step guide on how to calculate gear ratio:
- Identify the input and output gears in the gearbox.
- Count the number of teeth on the output gear (the gear connected to the output shaft).
- Count the number of teeth on the input gear (the gear connected to the input shaft).
- Plug the values into the gear ratio formula: GR = Number of Teeth on Output Gear / Number of Teeth on Input Gear.
- Calculate the gear ratio by performing the division.
The gear ratio provides insight into how much the input gear needs to rotate to achieve a certain rotation of the output gear. It influences torque, speed, and direction of rotation in the gearbox.

Our Advantages
High precision
A good percentage of harmonic gear reducer’s teeth are meshed at all times and are engaged at 2 zones 180 degrees apart. This means influences of tooth pitch errors and accumulated pitch errors on rotational accuracy are neutralized, which assures high positional and rotational accuracy.
Long service time
As a professional harmonic drive gearbox company and strain wave gear manufacturer in China, Hanzhen harmonic drive reducers with superior harmonic drive efficiency and long service time.
Light weight and compact size
While being less the size of conventional gearing mechanisms and less the weight, the strain wave reducer provides the same levels of torque and speed reduction ratios as its conventional counterparts enabling machinery and equipment to be made smaller and lighter.
High speed reduction ratio
A harmonic gear reducer has high single-stage reduction ratios also known as harmonic drive gear ratio or harmonic drive ratio of 1/30-1/500. Three basic components along same axle without complex structures can provide high reduction ratios.
High torque capacity
Each tooth subjected to a negligible amount of force yet provides a high torque capacity because of the way the teeth come into contact with each other and because a good percentage of the teeth in the flex spline is engaged at all times.
Minimum vibration and quiet
Hanzhen harmonic drive reducers also operate with quiet and minimal vibration.

Importance of Lubrication in Gearbox Performance
Lubrication plays a critical role in ensuring the optimal performance, longevity, and reliability of gearboxes. Proper lubrication provides several key benefits:
- Reduces Friction and Wear: Lubrication forms a protective layer between gear teeth, bearings, and other moving components, reducing friction and minimizing wear and tear.
- Heat Dissipation: Lubricants help dissipate the heat generated during gear operation, preventing overheating and potential damage to components.
- Noise Reduction: Adequate lubrication can dampen noise and vibration produced by gear meshing, leading to quieter and smoother operation.
- Sealing and Contaminant Prevention: Lubricants create a barrier that seals out contaminants like dust, dirt, and moisture, preventing their entry and reducing the risk of corrosion and damage.
- Enhanced Efficiency: Proper lubrication reduces energy losses due to friction, improving the overall efficiency of the gearbox.
- Extended Lifespan: Lubrication helps prevent premature component wear and failure, extending the lifespan of the gearbox and minimizing the need for costly repairs or replacements.
- Optimal Performance: Gearboxes operate within specified tolerances when properly lubricated, ensuring they deliver the intended performance and functionality.
It’s essential to use the recommended lubricant type, viscosity, and change intervals specified by the gearbox manufacturer to ensure the best possible performance and longevity. Regular monitoring and maintenance of lubrication levels are crucial to preserving the health of the gearbox and its components.
