Kartiohammaspyörästöjen

Kartiohammaspyörä, often translated as conical gear, is a type of gear that meshes with another conical gear to transmit rotational motion. The teeth on a kartiohammaspyörä are cut on the surface of a cone. This allows for the transmission of power between shafts that are not parallel, typically intersecting at an angle. The most common application is for shafts that meet at a 90-degree angle, though other angles are possible.

The shape of kartiohammaspyörä allows for the ratio of speeds between the two shafts to be changed by altering the relative sizes of the two gears. The pitch cone of the gears is the imaginary cone that rolls without slipping on the pitch cone of the mating gear. The tooth profiles are designed to maintain this rolling contact and ensure smooth engagement.

There are several types of kartiohammaspyörä, including straight-cut, spiral, and hypoid gears. Straight-cut kartiohammaspyörä have teeth that are straight and parallel to the axis of rotation, similar to spur gears. Spiral kartiohammaspyörä have teeth that are cut at an angle, which allows for smoother and quieter operation compared to straight-cut gears. Hypoid gears are a type of spiral kartiohammaspyörä where the shafts do not intersect but are offset. This design is common in automotive differentials.

The design and manufacturing of kartiohammaspyörä require precise calculations to ensure proper meshing, strength, and durability. They are widely used in various mechanical systems, including automotive transmissions, industrial machinery, and power tools, wherever a change in direction of rotation is needed between non-parallel shafts.
