A spiral bevel gear drive's sophistication and superior performance offer the engineer many opportunities. In a typical right angle gear, the perpendicular alignment of the gear teeth can cause noise, unpredictable operating cycles, and other issues. Spiral bevel gears have teeth designed to mesh on the diagonal, making the transmission of force smooth, quiet, and powerful.
A spiral bevel gear can also significantly reduce backlash when correctly calibrated. In most instances, this is achieved with a shim or retaining ring. MITRPAK spiral bevel gear drive features a unique locknut for faster, more precise adjustment. Few gears outmatch a MITRPAK spiral bevel gear drive in performance, speed, and ingenuity.
Minimizing Noise In Right Angle Gear Drives
Spiral bevel gear drives are precisely fitted to minimize the distance between enmeshed gears. The reduced space between the gear teeth means less opportunity for backlash and noise during operation as the teeth connect. Thus, the quieter operation of spiral bevel gears is ideal to utilize in environments where noise reduction is a priority.
Spiral Bevel Gear Drives for High-Torque and High-Speed Applications
Because spiral bevel gears have a greater tooth area, they can deliver more torque output than other gears of the same size. Spiral bevel gears, as a result, can move faster than other gears, producing greater output in less time. In industrial applications, spiral bevel gears offer strength and robust transmission of force.
Smooth Operation Keeps Gear Drives Cool
Smooth operation comes naturally with the higher speed and precision of a spiral bevel gear. Equipment utilizing a spiral bevel gear drive benefits from reduced strain, less friction, and lower heat generation. This feature is essential in scenarios where heat and safety are a concern, especially in industrial applications requiring prolonged continuous operation. As the teeth of typical gears make contact, the impact and friction can cause a host of problems: heat output, backlash or recoil, and erratic operation cycles' just to name a few! On the other hand, spiral bevel gears minimize friction and impact between gear teeth with minimal backlash and consistent, predictable cycle times.
Spiral Bevel Gears Minimize Need for Repairs or Replacements
Spiral bevel gears are often higher in quality and last longer than other types of gears, requiring less need for maintenance repairs. While some may require frequent lubrication and calibration, MITRPAK® spiral bevel gear drives have double-shielded, permanently lubricated and sealed bearings, an aluminum alloy housing, and hardened steel gears for optimal performance with minimal maintenance requirements.
Spiral Bevels Lead the Way in Right Angle Gears
When it comes to right angle gear performance there's no question about it' spiral bevel gears are the discerning engineer's top choice. From sporting arena seating to heavy industrial equipment, spiral bevel gear drives offer enticing benefits for any operating scenario. Explore MITRPAK and discover the right angle gear drive to optimize your equipment design today.

Straight or Spiral Bevel Gearboxes - What's Better?
Bevel gears enable us to operate a vast array of machinery, massive or small, so they are indispensable in many industrial applications. A bevel gearbox is particularly useful because, just by the way the components integrate with one another, it can control the speed and amount of power delivered to an output shaft while changing rotational direction.
Usually a bevel gear is conical in shape. The teeth that come together to drive the gear can be arranged straight up and down, or they can be curved to form a spiral design. Either way, the teeth taper toward the cone's apex.
So Which Style of Gearbox is Better?
Either type of bevel gearbox will work when:
- The shafts intersect at odd angles (commonly right angle)
- The shafts are on the same plane
- The shaft has to change rotational direction
However, as always with industrial equipment, what is 'best' depends on your specific application and operating environment. Some considerations are functional, while others may be preferential.
Advantages of Spiral Bevel over Straight Bevel in a Gearbox
Spiral bevel gears typically cost more than those with straight teeth, but for many installations, the benefits will-outweigh the cost difference:
- Noise. As the gears rotate, straight teeth impact one another all at once, so they produce a clattering noise that can be significant in medium- and high-speed operations. Spiral teeth mesh gradually as they turn, so operation is significantly quieter.
- Shock loading. The sudden impact of straight teeth coming together while rotating also increases the risk of shock loading, which can cause undue wear or damage and premature replacement.
- Vibration. Spiral teeth are not only quieter, but their smoother operation also produces less vibration making them more efficient.
- Axial thrust. The conical shape of bevel gears causes them to produce axial thrust as they rotate. In spiral bevel gears, the axial force changes depending on the rotational direction due to the curved tooth design.
- Overheating. Straight teeth bevels are in contact more, increasing friction, and the chance for overheating equipment.
- Strength and durability. Because they endure greater initial and ongoing impact, straight teeth are more likely to break. Spiral teeth are concave (or convex, depending on the side you're looking at). Their curved shape is inherently stronger, and ongoing wear is reduced by gradual, rather than sudden, meshing impact and the fact that several teeth are engaged at any given time.
Spiral bevel gearboxes are ideal for applications such as cooling towers, wind turbines, steel manufacturing, packaging and food processing, material handling, robotics, printing presses, and so on ' anywhere that requires any or all of these performance characteristics:
- High speeds
- Speed reduction
- High torque
- Frequent load cycles or continuous operation
Teeth Aren't the Only Factor in Choosing the Right Gearbox
As useful and versatile as spiral bevel gearboxes can be, some industrial designs call for a different type of gear - helical gears or worm gears.
You'll need to consider not only gear style but gearbox size, gear ratio, configuration, etc. The video below explains the differences and options among our styles of right-angle gearboxes and the design/performance implications of those differences.
All of W.C. Branham's right-angle gearboxes are also available in stainless steel.
The Right Supplier is as Important as the Right Product
It is critical to find exactly the right gearboxes for your installation because what you choose will affect future productivity and cost-effectiveness. But there are other factors that affect those results, and they all come down to the manufacturer:
- Long-standing reputation for innovation and quality
- Reliable product availability
- Responsive, proactively helpful customer service
- Custom from-scratch design or product modifications
At W.C. Branham, we are proud that our company embodies all of these traits. We introduced the concept of a right-angle hollow-core helical gearbox that is pre-lubricated and leak-proof. But that's just one example of our dedication to pursuing Solutions in Motion.
