Plastic Spur Gear, 20 Teeth (T20), Blue

Plastic Spur Gear, 20 Teeth (T20), Blue

This lightweight mechanical component transfers rotational motion by meshing with a compatible gear mounted on a parallel shaft. Engagement between the gear teeth mechanically couples the shafts, allowing rotational movement to be transmitted through a simple gear mechanism.

Product Specifications

Applications and Benefits:

• Demonstrates the transfer of rotational motion between parallel shafts in educational mechanical assemblies.
• Supports hands-on experiments involving gear ratios and rotational speed relationships.
• Illustrates speed reduction and speed increase when combined with compatible gears having different tooth counts.
• Helps explain the relationship between gear ratios, rotational speed, and transmitted torque.
• Demonstrates how directly meshed spur gears rotate in opposite directions.
• Supports classroom STEM activities, mechanical engineering demonstrations, and science experiments.
• Can be incorporated into compatible small DC motor mechanisms and motorized science models.
• Suitable for educational robotics prototypes, hobby mechanisms, and custom mechanical projects.
• Provides a lightweight mechanical component for low-load assemblies.
• Can be reused in hands-on experiments involving mechanical power transmission and gear engagement.
• Supports problem-solving, observation, critical thinking, and scientific reasoning through mechanical experimentation.

Caution:

Dimensions are approximate. Verify shaft diameter, manufacturing tolerances, gear alignment, and tooth compatibility before installation. The 3.2 mm center bore provides a loose fit with the AXLE3MM 3 mm metal axle and a closer nominal fit with PWHEELSA 1/8 inch axle rods. Actual fit depends on component tolerances and materials. Mechanical attachment or shaft retention may be required depending on the application.

This product includes one blue 20-tooth plastic spur gear only. Axles, motors, and additional gears are sold separately. Intended for educational, hobby, and light-duty mechanical applications. Not intended for automotive, industrial high-load, or safety-critical mechanisms.
