Kartiohammaspyörissä

Kartiohammaspyörissä refers to the Finnish term for bevel gears. Bevel gears are a type of gear that transmit motion between shafts that are not parallel, typically at a 90-degree angle. They are characterized by their conical shape, with teeth cut along the surface of the cone. This conical design allows for the efficient transfer of rotational power between intersecting axes.

The most common type of bevel gear is the straight bevel gear, where the teeth are straight and parallel to the axis of rotation. However, more complex designs like spiral bevel gears exist, featuring curved teeth that provide smoother and quieter operation, along with increased load-carrying capacity. The precise cutting of the teeth on bevel gears is crucial for their performance, ensuring proper meshing and minimizing wear.

Bevel gears are widely used in various mechanical applications. They are commonly found in automotive differentials, allowing for power to be transmitted to the wheels at different speeds when turning. They are also utilized in machine tools, industrial machinery, and other systems where a change in the direction of rotation is required. The ability to transmit power at an angle makes them indispensable in many engineering designs.
