Plastic Helical Gear

Features of Helical Gears:

Plastic helical gears, having their teeth cut at an angle, are widely used. The meshing between a helical gear and a worm is smoother and quieter than spur gears since the teeth on helical gears are specially cut at an angle, so when 2 teeth on the gear system engage, it starts a contact on 1 end of the tooth, which gradually spreads with the gear rotation, until the time when both the tooth are fully engaged.

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 Gars:

  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.
