Product Description: Introducing the KELVIN Large Gear Box #841219, an educational kit designed for school projects. This kit, brought to you by KELVIN, provides an engaging hands-on experience for students to learn about gears and mechanics. With its comprehensive contents and clear instructions, it offers a fun and educational opportunity for young learners to explore the world of engineering. The KELVIN Large Gear Box #841219 includes the following components: a motor, worm gear, gear (5mm), axle, bracket, strip of tubing, self-tapping screws, lock washers, and an instruction sheet. The kit requires the use of basic tools such as a hammer, needle nose pliers, screwdriver, and hobby knife, which can be obtained from Kelvin (tools available in their catalog or on their website at www.Kelvin.com). Safety is a top priority, and adult supervision is advised during assembly to prevent any potential injuries. Teachers are encouraged to modify the activity to suit their specific teaching needs and ensure a safe learning environment for students. To assemble the kit, carefully follow the provided instructions. Start by identifying each component and working with the bracket and axle. File or sand the ends of the axle to eliminate any rough edges. Insert one end of the axle through a side hole in the bracket and secure it by tapping the free end with a hammer, driving the axle into the gear. Use a vice or a similar device to support the bracket while tapping the axle. To prevent lateral movement of the gear, two pieces of tubing are included. Slit each piece lengthwise using needle nose pliers and a hobby knife, and then slide them onto the axle on either side of the gear. The motor should be lined up with the slot on the bracket and attached using the self-tapping screws and lock washers (avoid over-tightening). The worm gear can be pressed onto the motor shaft, ensuring that the gear teeth are properly meshed. A final test can be performed by connecting the kit to a D.C. power source (maximum 9 volts). Please note that the KELVIN Large Gear Box #841219 is intended for educational purposes and requires adult supervision. It should not be used by young children. By using this kit, you acknowledge and accept the associated risks and use it at your own discretion.
