Helical Teeth Gears

Your Professional Helical Teeth Gears Manufacturer!

 

Kunshan Devotec Automation Co., Ltd. was established in 2012, but its origins trace back to an initial investment by the German company WMH HERION in Qingdao, Shandong Province in 2007. Since then, we have accumulated extensive experience in engineering, manufacturing, and quality control. As a specialist in drive technology, Kunshan Devotec Automation focuses on the production of high-precision gear racks, gears, pinions, gearboxes, linear guideways, and other linear transmission components. The company also serves as a partner for several European manufacturers in China, including , Graessner, and Hönger, providing localized sales and after-sales services.

Advantages of Helical Teeth Gears

 

 

Smooth and Quiet Operation

Helical teeth gears provide smooth and quiet operation due to their gradual tooth engagement. The helical tooth design reduces impact forces and noise, making them suitable for applications where noise reduction is desired, such as in automotive transmissions or machinery in noise-sensitive environments.

High Load-Carrying Capacity

Helical teeth gears have a larger contact area between teeth compared to spur gears, resulting in enhanced load distribution. This enables helical gears to transmit higher loads and handle greater torque, making them suitable for heavy-duty applications.

Efficient Power Transmission

Helical teeth gears offer high efficiency due to their tooth engagement characteristics. The gradual contact between teeth reduces sliding friction and power losses, resulting in efficient power transmission, especially at higher speeds.

Versatility in Speed Ratios

Helical teeth gears can achieve a wide range of speed ratios. By adjusting the helix angle and the number of gear teeth, various speed ratios can be achieved to suit specific application requirements.

Bidirectional Capability

Helical teeth gears allow bidirectional operation, enabling motion in both directions by simply reversing the direction of rotation. This bidirectional capability provides versatility and control in applications where reversible motion is required.

 

Applications of Helical Teeth Gears
 

Automotive Industry
In the automotive industry, helical teeth gears are used in gearboxes, differentials, and transmission systems. Their smooth and quiet operation makes them ideal for vehicles where comfort and performance are a priority.

 

Industrial Machinery
Helical teeth gears are commonly found in industrial machinery, including pumps, compressors, and conveyor systems. They are used to transmit high torque and ensure the smooth functioning of heavy-duty equipment.

 

Marine Applications
In marine applications, helical teeth gears are used in ship propulsion systems and other marine equipment. Their ability to withstand high loads and provide smooth operation makes them essential in the maritime industry.

 

Power Transmission Systems
Helical teeth gears are used in power transmission systems where efficient and reliable power distribution is crucial. Their ability to handle high torque and provide smooth power transfer makes them ideal for these applications.

 

Robotics and Automation
In robotics and automation, helical teeth gears are used in actuators, servo motors, and other robotic systems. Their precision and smooth operation ensure the accurate and reliable movement of robotic parts.

 

Types of Helical Teeth Gears
 

Single Helical Gears

 

These gears have teeth angled to the gear face, typically between 15 and 45 degrees. They are commonly used in pairs to transmit motion and power between parallel shafts.

Double Helical Gears (Herringbone Gears)

In this design, teeth on opposite sides of the gear slope in opposite directions. This configuration ensures smooth and quiet meshing while reducing axial thrust forces.

Spiral Bevel Gears

 

Ideal for transmitting motion and power between non-parallel shafts, these helical gears have inclined teeth and are arranged at an angle to each other. They excel in applications with misaligned shafts.

Hypoid Gears

 

These spiral bevel gears with teeth offset from the gear center offer higher gear ratios and increased load-carrying capacity. They are often found in automotive transmissions.

FAQ

 

Q: How long is your delivery time?

A: If the item is in stock, it's usually 5-10 days. If the item is not in stock, it's 15-20 days, depending on the quantity.

Q: Do you provide samples? Are they free or additional?

A: Yes, we can provide free samples, but we don't cover the shipping costs.

Q: What is a helical gear?

A: A helical gear is a type of cylindrical gear with teeth cut at an angle (helix) to the axis of rotation. This design enables gradual engagement between gear teeth, resulting in smoother, quieter, and more efficient power transmission compared to spur gears.

Q: What are the benefits of helical gears over spur gears?

A: The benefits of helical gears include smoother motion due to gradual tooth engagement, higher torque transmission, better efficiency, and quieter operation. They also offer more tooth contact, which helps distribute the load more evenly and increases lifespan.

Q: What is the difference between helical gears and bevel helical gears?

A: Bevel helical gears combine the features of bevel and helical gears. While standard helical gears are used for parallel or crossed shafts, bevel helical gears are designed for applications where power needs to be transferred between intersecting shafts, offering enhanced strength and smooth meshing.

Q: What makes helical gears suitable for high-load applications?

A: Helical gears are designed with angled teeth that allow multiple teeth to engage simultaneously. This load distribution minimizes wear and improves torque handling, making them suitable for high-load and high-speed applications.

Q: Can helical gears operate at high speeds?

A: Yes, helical gears can efficiently operate at high speeds due to their smooth and gradual tooth engagement. This reduces noise and vibration, making them ideal for high-speed gearboxes and motor-driven systems.

Q: Why are helical gears preferred for quiet operations?

A: Due to their angled tooth design, helical gears engage gradually rather than all at once, which reduces impact, vibration, and noise. This makes them highly preferred in applications requiring low-noise environments, such as HVAC systems and precision instruments.
