Tandgeometri

Tandgeometri refers to the study and design of the shapes and profiles of gear teeth. It is a crucial aspect of gear engineering, as the precise geometry of gear teeth determines how they mesh, transmit power, and withstand stress. The primary goal of tandgeometri is to achieve smooth, efficient, and quiet power transmission while minimizing wear and preventing failure.

Key elements of tandgeometri include the involute profile, which is the most common tooth shape used in modern gears. This curve ensures that the contact point between meshing teeth moves smoothly along the line of action, resulting in constant velocity transmission and reduced vibration. Other important considerations are the pressure angle, which affects the force transmitted and the size of the gear, and the addendum and dedendum, which define the height of the teeth above and below the pitch circle, respectively.

Proper tandgeometri also takes into account factors such as backlash, the small gap between meshing teeth, which is necessary to prevent binding and allow for lubrication, and tooth root fillet, the curved transition from the tooth flank to the root, which is critical for stress distribution and preventing fatigue failure. The design process involves complex calculations and often utilizes specialized software to optimize tooth profiles for specific applications, considering factors like load, speed, material, and desired lifespan.
