Kartiohammaspyörien

Kartiohammaspyörät, also known as bevel gears, are a type of gear that mesh together at an angle. They are typically used to transmit rotational motion between shafts that are not parallel. The teeth of a bevel gear are cut on the surface of a cone, and when two bevel gears are meshed, their conical surfaces appear to roll against each other. This conical geometry allows for efficient transfer of power and torque between intersecting shafts.

There are several common types of bevel gears, including straight bevel gears, spiral bevel gears, and hypoid gears. Straight bevel gears have teeth that are straight and taper towards the apex of the cone. Spiral bevel gears have teeth that are curved, similar to helical gears, allowing for smoother and quieter operation, as well as higher load-carrying capacity. Hypoid gears are a type of spiral bevel gear where the axis of the driven gear is offset from the axis of the driving gear, allowing for a lower mounting position of the drive shaft.

The primary application of kartiohammaspyörät is in situations where a change in the direction of rotation is required, such as in automotive differentials, industrial machinery, and power transmission systems. Their ability to connect shafts at various angles makes them a versatile component in mechanical engineering. The precise angle between the shafts dictates the specific design and tooth geometry of the bevel gears used.
