Engrenage conique

Les engrenages coniques sont des engrenages où les axes des deux arbres se croisent et où les faces portant les dents des engrenages eux-mêmes ont une forme conique. Les engrenages coniques sont le plus souvent montés sur des arbres espacés de 90 degrés, mais peuvent également être conçus pour fonctionner sous d'autres angles. La surface primitive des engrenages coniques est un cône.

Deux concepts importants dans l'engrenage sont la surface de pas et l'angle de pas. La surface primitive d'un engrenage est la surface édentée imaginaire que vous obtiendriez en faisant la moyenne des sommets et des vallées des dents individuelles. La surface primitive d’un engrenage ordinaire a la forme d’un cylindre. L'angle de pas d'un engrenage est l'angle entre la face de la surface de pas et l'axe.

Les types d'engrenages coniques les plus courants ont des angles de pas inférieurs à 90 degrés et sont donc en forme de cône. Ce type d’engrenage conique est appelé externe car les dents de l’engrenage pointent vers l’extérieur. Les surfaces primitives des engrenages coniques externes engrenés sont coaxiales avec les arbres d'engrenage ; les sommets des deux surfaces se trouvent au point d'intersection des axes de l'arbre.

Les engrenages coniques qui ont des angles de pas supérieurs à quatre-vingt-dix degrés ont des dents qui pointent vers l'intérieur et sont appelés engrenages coniques internes.

Les engrenages coniques qui ont des angles de pas d'exactement 90 degrés ont des dents qui pointent vers l'extérieur parallèlement à l'axe et ressemblent aux pointes d'une couronne. C'est pourquoi ce type d'engrenage conique est appelé engrenage à couronne.

Les engrenages à onglets sont des engrenages coniques accouplés avec un nombre égal de dents et des axes à angle droit.

Les engrenages coniques obliques sont ceux pour lesquels la couronne correspondante a des dents droites et obliques.

Bevel gears materials

 

Bevel gears can be made from various materials depending on the specific application requirements. The choice of material is crucial to ensure the gear’s durability, strength, and resistance to wear. Here are some common materials used for manufacturing bevel gears:

1. Steel: Steel is a widely used material for bevel gears due to its excellent strength, durability, and wear resistance. Different grades of steel, such as carbon steel, alloy steel, and stainless steel, can be employed based on the specific application demands.

2. Cast iron: Cast iron is another popular material choice for bevel gears, especially in applications requiring high strength and resistance to shock and vibration. It offers good wear resistance and is relatively cost-effective.

3. Bronze: Bronze, particularly phosphor bronze or aluminum bronze, is selected for applications that involve high-speed and high-load conditions. Bronze provides good resistance to wear, corrosion, and galling, making it suitable for demanding environments.

4. Aluminum: Aluminum bevel gears are commonly used in lightweight applications where weight reduction is a critical factor. Aluminum gears offer low inertia, good corrosion resistance, and are often used in industries such as aerospace and robotics.

5. Plastics: Certain plastics, such as nylon, acetal, and polyethylene, are utilized for bevel gears in applications that require low noise, low weight, and resistance to chemicals or moisture. Plastic gears can provide cost-effective solutions for less demanding applications.

Bevel gears applications

 

Medical Devices: Bevel gears find applications in the medical industry, particularly in medical imaging equipment, surgical robotics, and diagnostic devices. They enable precise motion control and power transmission in these critical medical applications.

Power Tools: Many power tools, including drills, saws, and grinders, utilize bevel gears for power transmission. Bevel gears help transfer power from the motor to the cutting or grinding components, providing the necessary torque and speed conversion for efficient operation.

Marine: Bevel gears are extensively used in marine propulsion systems. They can be found in boat outdrives, marine transmissions, and other marine propulsion mechanisms, enabling the transfer of power from the engine to the propeller shaft.

Automotive: Bevel gears are extensively used in automotive systems. They are a crucial component of the differential, which allows the wheels to rotate at different speeds while maintaining torque distribution. Bevel gears are also employed in steering systems, powertrain assemblies, and transmission systems.

Industrial Machinery: Bevel gears play a vital role in industrial machinery. They are used in machine tools, printing presses, packaging equipment, conveyors, and textile machinery. Bevel gears facilitate the transmission of power and motion between different sections of the machines.

Aerospace: Bevel gears are utilized in aerospace applications. They are employed in helicopter rotor systems, aircraft landing gear mechanisms, and various other systems where angular motion transmission is required.

Robotics and Automation: Bevel gears are commonly found in robotics and automation systems. They are used in robotic arm mechanisms, conveyor systems, and other automated processes that require precise angular motion transmission.

Mining and Heavy Machinery: Bevel gears are employed in mining equipment, construction machinery, and heavy-duty applications. They are utilized in excavators, loaders, crushers, and other equipment that require high torque transmission for tasks such as excavation and material handling.

Agriculture: Bevel gears are used in agricultural machinery, such as tractors, combines, and irrigation systems. They facilitate power transmission and motion control in various agricultural operations.
