INGCO S-AG-LBG-AG68- Angle Grinder Large Bevel Gear-no.19

product details:

The gear and pinion in an angle grinder work together as a gear reduction system, transferring power from the motor to the grinding wheel at a slower, more controllable speed. Here’s a detailed breakdown of their roles:

Function:

• Gear Reduction: The primary function of the gear and pinion set is to reduce the motor’s high rotational speed to a slower and more manageable speed suitable for grinding applications. This allows for greater control and prevents the grinding wheel from spinning too fast, which could be dangerous or damage the material being worked on.
• Torque Increase: As a side effect of the gear reduction, the gear set also increases the torque (rotational force) delivered to the grinding wheel. This increased torque provides the grinding wheel with the necessary power to effectively grind, cut, or polish various materials.

Components:

• Gear: The gear is typically a larger, internally toothed wheel attached to the motor shaft. It receives the high-speed rotation directly from the motor’s rotor.
• Pinion: The pinion is a smaller gear with fewer teeth that meshes with the gear. It’s usually located on the shaft connected to the grinding wheel assembly.

Gear Ratio:

The gear ratio refers to the difference in size between the gear and pinion. It’s calculated by dividing the number of teeth on the gear by the number of teeth on the pinion. For example, if the gear has 40 teeth and the pinion has 10 teeth, the gear ratio is 4:1.

• Impact of Gear Ratio: A higher gear ratio (larger gear compared to pinion) signifies a greater speed reduction and a more significant torque increase. Conversely, a lower gear ratio translates to less speed reduction and a smaller torque boost.
