Plastic Spur Gear

Features of Plastic Spur Gears:

Plastic spur gears are straight-toothed and have radial teeth to transmit power and motion between parallel axes. Plastic spur gears are widely used for a speed increase or reduction, high torque, and resolution for positioning systems since the cost of tooling for Plastic spur gears is lower.

About Plastic Gears

A gear is a toothed wheel designed to transmit force to another equipment or toothed component. The teeth of a gear can be shaped to minimize wear, vibration, and noise and maximize power transmission efficiency.

Gears of differing sizes are often used in pairs for a mechanical advantage, allowing the torque of the driving gear to produce an enormous torque in the driven gear at a lower speed or a smaller torque at a higher rate.

The Advantages of Plastic Gears:

  1. Plastic gears are easily molded into various shapes, giving them a more comprehensive range of configurations.
  2. Plastic gears are less expensive and are lighter in weight.
  3. Plastic gears are chemical and corrosion-resistant.
  4. Plastic gears have a quieter and smoother operation and offer more efficient drive geometry.
  5. Plastic gears are inherent self-lubricating.

While plastic gears offer these many advantages over metal gears, their practical use requires proper design and engineering to account for possible dimensional and property variations over the expected range of operating conditions.
