This is 5 gear set which is suitable for building a simple version of the small works of science and technology. Gears are machine elements that transmit motion by means of successively engaging teeth. The gear teeth act like small levers. Plastic gears also open new opportunities for more efficient transmissions in many products along with reduced drive drive-cost, weight, noise and wear
Features:
- Cost effectiveness of the injection-moulding process.
- Elimination of machining operations; capability of fabrication with inserts and integral designs.
- Low density, lightweight, low inertia. Uniformity of parts.
- Capability to absorb shock and vibration as a result of elastic compliance.
- Ability to operate with minimum or no lubrication, due to inherent lubrication.
- Relatively low coefficient of friction.
- Corrosion-resistance; elimination of plating, or protective coatings.
- Quietness of operation.
- Tolerances often less critical than for metal gears. due in part to their greater resilience.
- Consistency with trend to greater use of plastic housings and other components. One step production; no preliminary or secondary operations.
- Reduction in the overall lubrication of the gears.
