helical gear
Helical gears are similar to spur gears but offer the flexibility to drive either parallel axes or non-parallel, non-intersecting shafts. The key difference lies in the angled orientation of their teeth, which allows for multiple teeth to be in contact simultaneously. This design feature leads to quieter and smoother gear operation.
At Ever-power, we offer high-quality China-made helical gears in both left and right-handed versions. Our standard helical gears come with a 45-degree helix angle, designed to transmit power and motion between non-intersecting shafts, whether parallel or positioned at 90 degrees. To drive parallel shafts, gears with opposite-hand helix angles are used, while for 90-degree shafts, gears with the same helix angle are necessary.
A helical gear consists of two gears with opposite orientations, designed to direct axial forces toward the gear’s center. In a balanced setup, the total axial force on both gears equals zero, ensuring stability.
Due to their high torque transfer capability and well-structured gear teeth, helical gears are commonly used in heavy-duty machinery and construction equipment. They are known for their durability and adaptability, making them suitable for both parallel and perpendicular configurations, allowing manufacturers to customize machinery for various applications.
Helical gears can be made from materials such as carbon steel, aluminum, or bronze. While carbon steel is a cost-effective option, it is prone to corrosion and may not be as durable for certain uses. It is also more expensive to manufacture, making it a common choice for larger transmission systems.

Helical Gear Characteristics
Helical gears are characterized by their distinct design, featuring angled cuts along the edges of the gear teeth. This design significantly reduces friction, heat, and noise compared to other gear types. Each tooth meshes smoothly with the teeth of an opposing helical gear, which rotates in the opposite direction.
Like other gears, helical gears rotate by interlocking teeth, but they offer a more refined and gradual motion. This is primarily due to the way their teeth engage with the axis of rotation, which can either be parallel or crossed at a 90-degree angle.
Applications of Helical Gears
Helical gears are commonly used in automotive transmissions due to their smooth and quiet operation, making them ideal for high-speed and high-load applications. Unlike spur gears, they perform well on non-parallel shafts, making them a preferred choice in various industries, including food processing and rubber and plastics. With a higher load transfer capacity compared to spur gears, they are suitable for more demanding tasks.
Although helical gears are generally more cost-effective than spur and bevel gears, they have lower load capacity in parallel setups. A typical use for helical gears is in automobile oil pumps and distribution shafts. They are often compared to bevel gears, both of which are efficient for automotive transmissions, although bevel gears require more attention to heat and lubrication management. Helical gears also produce significant thrust due to the angled teeth, necessitating the use of thrust bearings to absorb these forces.
Helical Gears Advantages
Helical gears are well-suited for high-load applications because they have more teeth in contact during operation, which enhances their strength. They are versatile in their uses, as they can transmit motion and power on both parallel and right-angle axes. Additionally, the high degree of overlap between teeth increases the gear’s load-carrying capacity, making them highly efficient under heavy loads.
Helical gears are highly durable due to their large-degree of tooth engagement, which extends their lifespan by evenly distributing the load across the axles and reducing wear over time. The long engagement time of their numerous teeth minimizes wear and tear, while also reducing stress on the gear, which helps decrease noise and improve the efficiency of the drive. This makes helical gears suitable for higher speeds without significant power loss. When selecting a helical gear, it’s important to consider its intended use, including factors such as design, construction, tooth count, tooth angle, and lubrication, to ensure optimal performance.
Helical Gear VS Spur Gear
A helical gear has a significantly higher transmission capacity than a spur gear, due to its higher contact ratio, which also helps reduce noise and vibration. However, the manufacturing process for helical gears is more complex and, as a result, more expensive.
Helical gears feature two sets of teeth positioned on opposite sides of the gear’s axis, cut at an angle known as the helix angle. This angle determines the contact position with the mating gear. The most fundamental type of helical gear is the cross-axis helical gear.
Compared to spur gears, helical gears are larger and better suited for handling heavy loads. They are more efficient and produce less noise, making them ideal for high-speed mechanical systems. The key difference between the two types of gears lies in their tooth arrangement—helical gear teeth are not parallel to the axis, which allows for greater speed reduction and minimized vibration, ultimately enhancing performance and service life.
