Understanding The Different Bevel Gear Types

There’s only one gear type engineers rely on to facilitate torque transfer between intersecting shafts, especially at a right angle. The answer is a bevel gear. Bevel is a unique gear in many ways. Its counterparts, such as spur and helical, are cylindrical. Meanwhile, the bevel is a conically-shaped gear with impressive torque transmission capabilities. True Gear & Spline Ltd. is a leading gear manufacturer based in Cambridge, Ontario. Our decades of experience make us industry leaders and qualified to analyze the different types of bevel gears. So, read until the end.

Straight: Straight bevel gear gets its name thanks to its straight and radially aligned teeth. The teeth taper towards the apex of the pitch cone. The pitch cone is, of course, the imaginary cone on which the gear teeth are projected. Straight gears are best suited for low-speed applications. They are used in conveyors, differential & transmission systems, power tools, and mixers.

 

Spiral: These gears are perfect for a smoother and quieter operation. This can be attributed to the more gradual and progressive tooth engagement. Straight gears have a more abrupt tooth engagement, sometimes resulting in noisier operations. Teeth of a spiral gear are generally curved at an angle between 35 to 45 degrees. Common applications include in aircraft engines, helicopter transmissions, landing gear, and precision robotics.

 

Hypoid: The hypoid bevel gear is similar in geometry and design to spiral gears. However, the one major difference is that the hypoid gear has non-intersecting shafts. The pinion is positioned above or below the mating gear’s centre line to create an offset. This allows for better load distribution and superior torque transmission. Common applications include: marine propulsion systems, heavy machinery gearboxes, and heavy vehicle axles.
