Electric Chain Saw Gear Circular Spur Gear For Lawn Mower From Power Tool

The main function of the cylindrical gear in the electric chain saw is to transmit power and adjust the speed. In the transmission system of an electric chain saw, cylindrical gears usually cooperate with other gears to transmit the power of the electric motor or internal combustion engine to the saw chain wheel, thereby driving the saw chain for cutting. The specific functions of cylindrical gears include:

• Power transmission: The cylindrical gear transmits power from the engine to the saw sprocket by meshing with the saw sprocket's gear. This transmission is achieved through the interaction between the teeth of the gear.
• Speed ​​adjustment: If the electric chain saw is designed with a reduction mechanism, a cylindrical gear may be used to reduce the engine speed while increasing the torque. This is very important for a saw chain as it needs to have enough torque to get the job done while cutting.
• Direction change: In some designs, cylindrical gears can also be used to change the direction of power transmission, for example, converting vertical rotation to horizontal direction to adapt to the running path of the saw chain.
• Stability and durability: Cylindrical gears are typically made from wear-resistant materials, such as steel or cast iron, to ensure they can withstand the wear and tear of high-speed operation and heavy-load conditions. The precision with which they are designed and manufactured is critical to ensuring the saw chain operates smoothly and efficiently.

How the cylindrical gear in an electric chain saw works can be explained in the following steps:

• Power input: The electric motor or internal combustion engine of the electric chain saw generates power, which is transmitted to the transmission system through the clutch.
• Gear meshing: The meshing of cylindrical gears with other gears in the transmission system. The teeth of the cylindrical gear mesh with the teeth of the mating gear. When the driving gear rotates, the driven gear also rotates.
• Power transmission: As the gears rotate, power is transmitted to the sprocket through the meshing between the gears. The sprocket is part of the saw chain transmission system. It has a special tooth shape that meshes with the link part of the saw chain.
• Speed ​​and Torque Conversion: If the electric chain saw is designed with a reduction gearbox, cylindrical gears may be used to reduce engine speed while increasing torque. This conversion is achieved through a combination of gears of different sizes, with larger gears (reduction gears) reducing speed and increasing torque.
• Stable Operation: The design and manufacturing accuracy of cylindrical gears are critical to ensuring smooth, efficient operation of the saw chain. They need to be able to remain stable under high-speed operation and heavy-load conditions while reducing noise and vibration.
• Saw chain drive: The sprocket transmits power to the saw chain, and the cutting teeth of the saw chain rotate, contact and cut the wood.
