Everything you need to know about designs, applications, and selecting the right bevel gear.
What is a bevel gear and where is it used?
Ein Bevel gear is an angular gear that consists of two bevel gears and is used for transmitting rotary movements and torques between intersecting shafts, usually at a 90° angle. It is used in various applications, such as in the machine and plant engineering, in the packaging industry, in machine tools, in logistics, and in the automotive industry for redirecting drives.
What advantages do bevel gears from ATEK Drive Solutions offer?
ATEK Drive Solutions provides Bevel gear as part of a comprehensive system offering. Advantages include a high power density, compact design, and variety of models through a modular construction system. ATEK focuses on high-quality spiral-toothed gear sets made of hardened case steel, which ensure smooth running, shock and vibration resistance, as well as high load capacity . Additionally, they are maintenance-free for the specified use ..
Are there also disadvantages with bevel gears?
Yes, bevel gears have specific characteristics that need to be considered. They can have a more complex structure than spur gears. Depending on the type of gearing and operating conditions, they can generate higher running noises and potentially have a lower efficiency than, for example, planetary gears. They also generate axial forces that require careful bearing consideration.
What types of bevel gears are there and when do I choose which type?
The main types are straight-toothed, helical-toothed, and hypoid bevel gears. Straight-toothed are simple and cost-effective for low speeds. Helical-toothed provide better smoothness. Spiral bevel gears (standard at ATEK) are suitable for high speeds and torques with good smoothness. Hypoid bevel gears offer the highest torque capacity due to offset axes but require special oils. The selection depends on requirements for speed, torque, smoothness, precision, and installation space. ab.
How important is lubrication for bevel gears and are they maintenance-free?
Lubrication is crucial for the lifespan and performance of bevel gears, as it reduces friction, cools, and protects against wear. Many modern bevel gears, like those from ATEK Drive Solutions, come with lifetime lubrication and are maintenance-free under normal operating conditions. However, under extreme conditions or very long runtimes, oil changes may be recommended, such as in NEFF gears after 15,000 hours.
Can bevel gears be adapted to specific requirements?
Yes, many manufacturers, including ATEK Drive Solutions, offer extensive customization options. This ranges from different gear ratios, shaft configurations (solid shaft, hollow shaft), mounting flanges for motors to special solutions for specific installation situations or environmental conditions (e.g., stainless steel designs, hygienic design). ATEK’s modular construction system enables millions of configurations..
What does ‘low backlash’ mean in bevel gears and why is it important?
Backlash (also tooth flank play) is the small angle by which one shaft can be rotated without moving the other shaft. A low backlash is crucial for applications with high requirements for positioning accuracy, such as in robotics or precision machines. ATEK, for instance, offers bevel gears of the V-series with a backlash reduced to less than 6 arc minutes. an.
How does the design affect the efficiency and noise generation of a bevel gear?
The design has a significant impact. The efficiency (typically 94-98% with good design) is influenced by the type of gearing, surface quality, bearing, lubricant, and installation position. Losses can occur at high speeds and overfilling.The noise generation depends on the type of gearing (spiral gearing is quieter), tooth quality, speed, and the correct adjustment of the load distribution. At NEFF, the choice of rotation direction of the pinion can reduce noise by 1-2 dBA..

Understand: Master the basics of bevel gear technology.
Bevel gear enable the precise redirecting of rotary movements. This article explains their function, types, and selection for optimizing drive technology. Such angular gears are essential when rotary movements need to be transmitted at an angle, e.g., for precise product positioning in packaging machines via Bevel gear. Their ability to handle high torques during direction changes is central. The correct design influences performance and reliability. In mechanical engineering, the compactness and power density of these drive elements are used. ATEK Drive Solutions GmbH offers solutions for this. Tooth geometry affects smoothness and lifespan, important for precision applications like robotics (precision gears for robots).
Basics and significance
The core function is the redirection of the drive axis (usually 90°). Efficiency depends on manufacturing precision and design. Example: machine tools. ATEK offers a variety of options for these redirecting gears.

They are widely used in the industry, adaptable to loads/speeds. Logistics requires robust designs for continuous operation (bevel gear motor).Apply: Exploit the potential of bevel gears in your industry.
Two toothed bevel gears with intersecting axes mesh with each other, transmitting torque and speed, thus converting input movement into an angularly offset output movement. The type of gearing (straight, helical, spiral-) determines the smoothness and torque capacity of these shaft gears. Presses use them, for example, for power transmission. Areas of application for Bevel gear range from rolling mills to medical technology, also in differential gears of the automotive industry. ATEK Drive Solutions GmbH serves industries such as machine engineering and the packaging industry, e.g., in compact packaging machines..

Precise gearing for Bevel gear is achieved through hobbing, milling, or precision forging. Modern processes such as 5-axis milling (Tandler) are gaining importance, allowing flexibility and contact pattern optimization (TCA analyses). ATEK Drive Solutions uses spiral gears made of hardened case steel for its drive solutions. Material selection (cast iron to high-strength steels) is crucial. ATEK uses robust housings made of gray cast iron/steel (V-/VS series). Special gearboxes are suitable for the food industry, such as designs in stainless steel or in Hygienic Design. Importance of lubrication.
Lubrication reduces friction, cools, and protects.
Choice (grease/oil, often synthetic) depends on speed, temperature, and application of the bevel gearbox. Wahl (Fett/Öl, oft synthetisch) hängt von Drehzahl, Temperatur, Anwendung des Winkelgetriebes ab. NEFF gearboxes: maintenance-free, oil change under extreme conditions after 15,000 h.
Modern manufacturing methods
5-axis milling enables complex tooth shapes without special tooling, advantageous for prototypes (Tandler).Design: Aim for top performance and precision.
Axial forces due to helical/spiral gearing at bevel gears. require careful bearing design. Insufficient axial support leads to wear/failure. Tandler focuses on transmission accuracy, minimal backlash, and contact pattern optimization. Efficiency (NEFF: 94-98%) and noise are critical for these bevel gearboxes. Installation position, seals, and lubricant influence efficiency; churning losses at high speeds. NEFF: The rotation direction of the small gear opposite to the spiral direction can reduce noise by 1-2 dBA (stage technology.).

Optimize efficiency
Lubricant selection, avoiding overfilling, and operating temperature influence efficiency. Careful design of the axle gearboxes is crucial.Ensure: Maximize longevity through proper maintenance.
Demand-driven maintenance ensures a long life of bevel gears.. “Maintenance-free” (Ganter) often refers to lifetime lubrication under normal conditions; extreme conditions may require maintenance. (NEFF: Oil change after 15,000 h in demanding applications). Regular inspections (leakage, noise) are important. Proper lubrication (type, amount) reduces wear. Observe manufacturer specifications. ATEK bevel gearboxes are designed for maintenance freedom under specification; monitoring remains advisable.
Inspection and early detection
Watch for oil leaks, increased temperatures, and changed running noises. These indicate wear/lubrication problems with the drive elements. Early diagnosis prevents damage. Condition-based maintenance (vibration measurement, oil analyses) is common.
Maximize lifespan
Avoid overload, correct mounting alignment, consider maximum torque/speeds and good heat dissipation are fundamental for the longevity of the bevel gearboxes.
