Product description
A 7-tooth pinion gear for a large chain typically refers to a small gear used in a drive system, meshing with a heavy-duty chain. This setup is common in applications such as minibikes, go-karts, ATVs, or industrial machines requiring robust power transmission. Here’s a breakdown of its features and considerations:
Key Characteristics:
1. Teeth Count (7 Teeth):
• A low number of teeth indicates a smaller gear diameter, which provides high torque but lower speed.
• Often used in applications requiring initial power for acceleration or climbing.
2. Chain Type:
• The term “big chain” likely refers to a heavy-duty chain such as #428, #530, or other industrial-grade chains.
• Ensure the pitch (distance between chain pins) matches the pinion gear.
3. Material:
• Pinions are usually made of hardened steel or similar durable materials to handle the stresses of heavy loads.
4. Bore and Mounting:
• Check the bore size to ensure it fits the output shaft of your engine or motor.
• May include set screws or a keyway for secure mounting.
5. Application:
• Used for power transfer in high-torque systems.
• Common in small engine drive systems, dirt bikes, or go-karts needing high torque.
Advantages of a 7-Tooth Pinion:
• High Torque Output: The smaller size increases torque for pulling or climbing.
• Durability: Designed to handle heavy-duty chains in rugged conditions.
• Compact Size: Ideal for systems where space is limited.
Considerations:
1. Gear Ratio:
• Pairing this pinion with a larger driven sprocket will amplify torque while reducing speed.
• Calculate the gear ratio by dividing the driven sprocket teeth by the pinion teeth (e.g., 7:35 for a 1:5 ratio).
2. Chain Compatibility:
• Ensure the chain pitch, roller diameter, and width match the gear.
3. Lubrication:
• Proper lubrication extends the life of both the pinion and the chain.
4. Wear and Tear:
• Smaller pinions can wear out faster due to higher stress on fewer teeth.
