Choosing between helical or spur gears for low backlash planetary designs

Introduction

Low backlash planetary gearboxes are one of the most widely used mechanical components in industries where high precision and high reliability is required. They are used in various applications such as robotics, aerospace, medical, automation, and more. However, when it comes to choosing between helical or spur gears for low backlash planetary designs, it can be a challenging task. In this article, we will explore the differences between helical and spur gears, and help you understand which one is best suited for your specific application.

What are helical gears?

Helical gears are a type of cylindrical gears that have teeth that are cut at an angle with respect to the gear axis. This angle is known as the helix angle. Helical gears are known for their smooth operation, low noise, and high load carrying capacity. They are widely used in applications where high precision and high torque is required. Helical gears produce less noise and vibration than spur gears and can transmit power more efficiently.

What are spur gears?

Spur gears are a type of cylindrical gears that have straight teeth that are parallel to the gear axis. They are the simplest and most commonly used type of gears. Spur gears are known for their high efficiency, low cost, and ease of manufacturing. They are widely used in various applications such as automobiles, home appliances, and power tools.

Helical vs Spur gears: Which one to choose for low backlash planetary designs?

When it comes to choosing between helical and spur gears for low backlash planetary designs, there are several factors that need to be considered:

Gear ratio

Helical gears are known for their high gear ratio capability. They can achieve a high gear ratio in a single stage, which makes them ideal for low backlash planetary designs. On the other hand, spur gears have a limited gear ratio capability and require multiple stages to achieve a high gear ratio.

Load carrying capacity

Helical gears have a higher load carrying capacity than spur gears. This is due to the larger contact area between the teeth in helical gears, which allows them to transmit higher torque. Spur gears have a lower load carrying capacity and are not suitable for high torque applications.

Efficiency

Spur gears have a higher efficiency than helical gears. This is because there is no sliding motion between the teeth in spur gears, which reduces the friction and energy loss. Helical gears have a lower efficiency due to the sliding motion between the teeth, which generates more heat and increases the energy loss.

Noise and vibration

Helical gears produce less noise and vibration than spur gears. This is due to the helical angle of the teeth, which reduces the impact between the teeth during the meshing process. Spur gears produce more noise and vibration due to the impact between the teeth, especially at high speeds.

Cost

Spur gears are less expensive than helical gears. This is because they are easier to manufacture and require less precision. Helical gears require more precision in the manufacturing process, which increases the cost.

Conclusion

Choosing between helical or spur gears for low backlash planetary designs depends on the specific application requirements. Helical gears are ideal for applications that require high torque and low noise, while spur gears are suitable for applications that require high efficiency and low cost. It is important to consider all the factors before making a decision.
