Arc Grinding Bevel Gear Wear-Resistant Metal Gear Set For Seven-Speed Bicycle

In a seven-speed bicycle, the bevel gear plays the following roles:

• Power Transmission: Bevel gears are used to transmit the power of the chain to the rear wheel. Because bevel gears can mesh at an angle, they effectively convert the linear motion of the chain into rotational motion of the rear wheel.
• Gearshift Mechanism: Bevel gears play a key role in a bicycle’s transmission, especially in multi-speed bikes. They help achieve smooth switching between different gears, thereby changing the transmission ratio and allowing the rider to ride on different terrains and speeds.
• Adjust and maintain gear clearance: The design of bevel gears allows the gear clearance to be adjusted through axial movement, ensuring that the gears are always maintained in the best meshing state, reducing wear and noise, and improving the performance and life of the transmission.
• Improve speed change accuracy: The conical design of bevel gears helps improve the accuracy of gear meshing, thereby improving the overall accuracy of the speed change system and making speed changes more accurate and smooth.
• Withstand high torque: Due to its structural characteristics, bevel gears are able to withstand high torque, which is especially important when the bicycle is climbing hills or accelerating.
• Reduce chain beating: Bevel gears can reduce chain beating during shifting and improve riding stability and comfort.
