Understanding the Benefits and Drawbacks of Helical Gears

Helical gears, a common type of gear used in various industries, offer a number of advantages over other gear types. However, they also come with their own set of challenges. In this article, we’ll delve into what makes helical gears unique, and why they might be the right choice for your application.

The Design and Function of Helical Gears

Distinctive in their design, the teeth of a helical gear are set at an angle relative to the axis of the apparatus, forming a helix shape. This unique design allows the teeth to mesh steadily, starting as point contact and progressing into line contact as engagement develops.

Advantages of Helical Gears

One of the major advantages of helical gears over other types, such as spur gears, is their reduced noise level, particularly at moderate to high speeds. In addition, multiple teeth are in constant mesh with helical gears, which reduces the load on each individual tooth. This results in a smoother transition of forces from one tooth to the next, thereby reducing vibrations, shock loads, and wear.

Challenges with Helical Gears

Despite their advantages, helical gears also have some drawbacks. The inclined angle of the teeth can cause sliding contact between the teeth, resulting in axial forces and heat, which can decrease efficiency. These axial forces play a significant role in bearing selection for helical gears. As the bearings have to withstand both radial and axial forces, helical gears require thrust or roller bearings, which are often larger and more expensive. Axial forces vary in proportion to the magnitude of the tangent of the helix angle. While larger helix angles provide higher speed and smoother motion, the helix angle is typically limited to 45 degrees due to the creation of axial forces.
