Plastic gears are commonly manufactured from engineering thermoplastics such as:
Acetal (POM): Excellent dimensional stability and low friction
Nylon (PA): Good wear resistance and toughness
Polycarbonate (PC): High impact strength
ABS: Good balance of strength and cost
PEEK: High-performance, heat-resistant material for demanding applications
Lightweight: Significantly lighter than metal counterparts
Corrosion resistant: Immune to rust and chemical corrosion
Quiet operation: Naturally dampen noise and vibration
Self-lubricating: Many plastics require minimal or no lubrication
Cost-effective: Lower material and manufacturing costs for many applications
Non-conductive: Electrically insulating properties
Lower load capacity: Generally cannot handle as much torque as metal gears
Temperature sensitivity: Performance degrades at elevated temperatures
Creep: Can deform under constant load over time
Thermal expansion: Higher coefficient than metals
Moisture absorption: Some plastics swell with humidity changes
Automotive components: Window regulators, seat adjusters, small motors
Consumer products: Printers, copiers, household appliances, toys
Medical devices: Pump drives, diagnostic equipment (single-use advantages)
Food processing: FDA-approved materials where lubrication contamination is a concern
Low-power transmissions: Where weight and noise are critical factors
Injection molding: Most common method for high-volume production
CNC machining: For prototypes or low-volume custom gears
3D printing: Rapid prototyping and custom small batches
Hobbling or milling: For specialized applications
Yes, plastic gears often work well with metal gears, particularly:
When the metal gear has a smooth finish to minimize wear
In applications where the plastic gear is the "sacrificial" component
With proper design considering different thermal expansion rates
Common in automotive and appliance applications
Consider reduced pressure angles (20° is common)
Use larger fillets and rounded edges to reduce stress concentration
Account for thermal expansion in backlash calculations
Design with thicker gear teeth than equivalent metal gears
Consider moisture absorption in dimensional tolerances
Many plastic materials are self-lubricating
When lubrication is needed, use compatible lubricants (some plastics degrade with petroleum-based lubricants)
Silicone-based or specialty plastic-compatible lubricants are often recommended
Consider solid lubricants (like PTFE) blended into the plastic compound
Plastic gear life depends on:
Material selection (wear properties)
Operating temperature
Load and speed conditions
Environmental factors (moisture, chemicals)
Quality of mating surfaces
Many manufacturers provide PV (pressure × velocity) limits for materials
While many metal gear standards (like AGMA) are adapted, specific considerations include:
AGMA 1006-A97: Design Manual for Flexible Couplings
ISO 1328-1: Cylindrical gears - ISO system of accuracy
Material-specific standards from resin manufacturers
Many companies develop proprietary design standards based on application experience
High-temperature environments (>150°C for most plastics)
Applications with high shock loads
Where extreme precision is required over wide temperature ranges
In chemically aggressive environments incompatible with available plastics
Very high-torque applications
Fiber reinforcement: Glass or carbon fibers for increased strength
Nanocomposites: Improved wear resistance and dimensional stability
Hybrid materials: Combinations of different plastics for optimized properties
Advanced mold flow analysis: For better manufacturing precision
High-temperature plastics: PEEK, PEKK, and other advanced polymers
