Advantages of metal gears
Metal gears have good durability, high transmission efficiency, good wear resistance, no frictional wear with bearings and other parts; internal structure is easy to control, reducing transmission system failure rate; strength can reach higher standards than commonly used plastic gears; higher surface hardness requirements; have a larger transmission ratio, more flexibility in use; can withstand greater loads, higher transmission efficiency.
So why should customers prefer innovative plastic gears for their machines rather than metal classics? Below we illustrate the characteristics and advantages that distinguish our vast production.
The characteristics of plastic gears compared to metal ones
Weight reduction:
The specific weight of plastic is almost 6 times lower than that of steel; this translates into a lower weight of the component and therefore of the entire application which affects performance and consumption;
Reduction of the transmission of vibrations:
On a mechanical level, plastic gears, compared to metal ones, have the ability to absorb vibrations. This is due to the intrinsic nature of technopolymers and plastics in general, which makes possible to dampen noise and therefore reduce the transmission of vibrations;
Self-lubrication capacity:
The molecular structure of the plastic guarantees such a low friction and wear coefficient that in some cases makes lubrication superfluous;
Resistance to high temperatures and chemical agents:
The evolution of technopolymers and plastic in general allows the use of our transmission elements in applications requiring high temperatures (up to 250°) and/or operating in chemically aggressive environments.
Reduction of machinery management costs:
Choosing the thermoplastic gears produced by Stagnoli means deciding for a durable and performing element, which requires not only less maintenance on the machinery, but also the elimination of a subsequent assembly phase of the components with an obvious reduction in time and costs.
USE OF PLASTIC GEARS: ADVANTAGES AND BENEFITS
So why prefer a polymer gear to a metal one? The advantages of this choice are all borne by the performance of the machinery, to optimise production times and costs:
Significantly decreased noise,Low weight for the benefit of the machinery,No lubrication is required. Reduction of the friction coefficient,Elimination of rust formation

How do plastic gears contribute to reducing noise and vibration?
Plastic gears contribute to reducing noise and vibration in various applications. Here’s a detailed explanation of how they achieve this:
Plastic gears possess inherent properties that help dampen noise and vibration during operation. These properties, combined with specific design considerations, contribute to the reduction of noise and vibration in the following ways:
- Damping Characteristics: Plastic materials have inherent damping characteristics, meaning they have the ability to absorb and dissipate vibrations. When compared to metal gears, which are stiffer and transmit vibrations more efficiently, plastic gears can effectively reduce the transmission of vibrations through their damping properties.
- Reduced Resonance: Plastic gears have the ability to attenuate resonant frequencies, which are frequencies at which vibrations can be amplified. By properly designing the tooth profile, gear geometry, and material selection, plastic gears can shift or dampen these resonant frequencies, preventing excessive vibration and noise generation.
- Tighter Gear Mesh Tolerances: Plastic gears can be manufactured with tighter gear mesh tolerances, which refers to the amount of clearance or backlash between mating gear teeth. Tighter tolerances lead to better gear engagement and reduced impact or vibration during gear meshing, resulting in quieter operation.
- Surface Finishes: The surface finish of plastic gears can be optimized to reduce friction and noise. Smoother gear surfaces reduce the potential for gear tooth noise and improve the overall meshing characteristics between gears. Proper lubrication or the use of self-lubricating plastic materials can further enhance the noise-reducing properties.
- Flexibility in Tooth Design: Plastic gears offer greater flexibility in tooth design compared to metal gears. Engineers can optimize the tooth profile and modify the gear geometry to minimize noise and vibration. For example, incorporating modifications such as profile shifting, tip relief, or helical teeth can help reduce gear noise by promoting smoother and more gradual tooth engagements.
By leveraging these characteristics and design considerations, plastic gears can effectively reduce noise and vibration levels in various applications. This makes them particularly suitable for use in noise-sensitive environments, such as consumer electronics, automotive components, or office equipment.
It’s important to note that while plastic gears can contribute to noise and vibration reduction, the specific noise performance also depends on other factors within the overall system, such as gear arrangement, supporting structures, and the presence of other noise sources. Therefore, a holistic approach to noise reduction should be considered when incorporating plastic gears into a design.
Are there specific design considerations for using plastic gears?
Yes, there are specific design considerations that need to be taken into account when using plastic gears. Here’s a detailed explanation of these considerations:
1. Material Selection: Choosing the right plastic material for the gear application is crucial. Different plastic materials have varying mechanical properties, such as strength, stiffness, and wear resistance. Consider factors such as load-bearing requirements, operating temperatures, environmental conditions, and compatibility with lubricants. It’s important to select a plastic material that can withstand the specific demands of the application.
2. Gear Geometry: The design of plastic gears should consider factors such as tooth profile, module or pitch, pressure angle, and tooth thickness. The gear geometry should be optimized to ensure proper meshing, efficient power transmission, and minimal noise and vibration. The design should also take into account the limitations and capabilities of the plastic material, such as its ability to form precise tooth profiles and maintain dimensional stability.
3. Clearances and Tolerances: Plastic gears may require different clearances and tolerances compared to metal gears. The coefficient of thermal expansion, dimensional stability, and manufacturing processes of plastic materials can affect the gear clearances. It’s important to consider the thermal expansion characteristics of the specific plastic material and provide appropriate clearances to accommodate temperature variations. Tight tolerances may result in binding or increased friction, while excessive clearances can lead to backlash and reduced gear accuracy.
4. Load Distribution: Distributing the load evenly across the gear teeth is essential for preventing premature wear and failure. Consider gear design elements such as tooth profile, tooth width, and the number of teeth to optimize load distribution. Reinforcing the gear teeth with fillets or other strengthening features can help improve load-bearing capacity and reduce stress concentrations.
5. Stiffness and Deflection: Plastic gears generally have lower stiffness compared to metal gears. The design should consider the potential for deflection or deformation under load. It may be necessary to increase the gear size, modify the tooth geometry, or incorporate additional support structures to enhance stiffness and minimize deflection. Analytical tools and simulations can be employed to assess and optimize gear design for stiffness and deflection.
6. Lubrication and Wear: Proper lubrication is important for the performance and durability of plastic gears. Consider the lubrication requirements of the specific plastic material and design features that facilitate effective lubricant distribution. Pay attention to potential wear mechanisms, such as adhesive wear or abrasive wear, and incorporate measures to minimize wear, such as optimized tooth profiles, lubricant selection, and sealing mechanisms.
7. Environmental Factors: Plastic gears may be subjected to various environmental factors such as temperature extremes, humidity, chemicals, and UV exposure. Evaluate the potential impact of these factors on the gear material and design. Select plastic materials that offer resistance to environmental degradation and consider protective measures, such as coatings or encapsulation, to enhance the gear’s resistance to environmental conditions.
8. Manufacturability: Consider the manufacturability of plastic gears during the design phase. Different plastic materials may have specific requirements or limitations for manufacturing processes such as injection molding or machining. Design features that facilitate efficient and cost-effective production, such as draft angles, parting lines, and tooling considerations, should be taken into account.
By considering these specific design considerations, such as material selection, gear geometry, clearances, load distribution, stiffness, lubrication, environmental factors, and manufacturability, it’s possible to optimize the design and performance of plastic gears for various applications.
