3. Setup and Assembly
These differential gear sets are designed for self-assembly and integration into larger MOC projects. Each bundle contains 4 sets of a specific generation of differential gear. Please identify the generation of your parts using the images below to ensure correct assembly.
3.1 First Generation Differential Gear (JM0045)
The First Generation differential (Part ID: JM0045) typically includes one main housing unit and three smaller gears for internal mechanism. Assemble the gears within the housing as shown in Figure 2.
3.2 Second Generation Differential Gear (JM0025)
The Second Generation differential (Part ID: JM0025) also comprises one main housing and three gears. Follow the visual guide in Figure 3 for proper gear placement and housing assembly.
3.3 Third Generation Differential Gear (65414, 6589, 65413)
The Third Generation differential involves specific parts: 1 piece of 65414, 5 pieces of 6589, and 1 piece of 65413. Refer to Figure 4 for the arrangement and connection of these components to form the complete differential unit.
3.4 Fourth Generation Differential Gear
The Fourth Generation differential includes a main unit and two distinct smaller gears. Position the smaller gears correctly within or around the main unit as depicted in Figure 5.
3.5 Fifth Generation Differential Gear
The Fifth Generation differential features a main unit and a more complex arrangement of several smaller gears and components. Carefully assemble these parts according to the visual guidance in Figure 6 to ensure proper function.
4. Operating Principles
A differential gear system allows two output shafts to rotate at different speeds while being driven by a single input shaft. In the context of MOC vehicles or mechanisms, this is crucial for:
- Turning: Enabling wheels on the same axle to rotate at different speeds when a vehicle turns, preventing wheel slip and improving maneuverability.
- Power Distribution: Distributing power effectively to different parts of a mechanism, especially in complex drive systems.
- Speed Synchronization: Allowing connected components to maintain different rotational speeds as required by the design.
Once assembled and integrated into your MOC, the differential will automatically adjust the rotational speeds of connected components based on resistance and movement.
5. Maintenance
To ensure the longevity and optimal performance of your Stemedu MOC building block parts, follow these maintenance guidelines:
- Cleaning: Regularly clean the parts with a soft, dry cloth to remove dust and debris. For stubborn dirt, a slightly damp cloth can be used, followed by thorough drying. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the parts in a clean, dry environment away from direct sunlight and extreme temperatures. Keep them organized to prevent loss or damage.
- Inspection: Periodically inspect the gears and housing for any signs of wear, cracks, or damage. Replace any damaged parts to maintain structural integrity and function.
- Lubrication: These plastic building block parts typically do not require lubrication. Applying lubricants may attract dust and hinder performance.
6. Troubleshooting
If you encounter issues with your differential gear parts, consider the following troubleshooting steps:
- Parts Not Fitting: Ensure you are using the correct generation of parts for your intended assembly. Double-check the part IDs against the product specifications and images. Apply gentle, even pressure during assembly; do not force parts together.
- Gears Not Rotating Smoothly: Disassemble the unit and check for any foreign objects (dust, small debris) obstructing the gears. Ensure all gears are correctly aligned and seated within their respective positions.
- Missing Parts: While kits are checked for completeness, if you believe parts are missing, carefully review the package contents and compare them against the expected components for your specific differential generation.
- Breakage: If a part breaks during assembly or use, it may be due to excessive force or material fatigue. Replace the broken component.
