The tooth flank is the functional surface of a rack tooth that engages with a pinion to transmit motion and power in linear drive systems.
In rack-and-pinion systems, the tooth flank refers to the precisely machined side surfaces of the rack teeth that make contact with the pinion teeth. These surfaces are designed with specific geometric profiles (typically involute or cycloidal) to ensure smooth, efficient power transmission with minimal backlash and wear. The tooth flank's accuracy directly affects the system's precision, noise levels, and longevity.

The tooth flank refers to the side surfaces of the tooth that engage with mating gear teeth, while the tooth face typically refers to the top surface. The flank is the functional contact surface for power transmission.
Proper flank geometry ensures efficient power transmission, minimizes noise and vibration, reduces wear, and maintains precision in motion control systems.
Flank quality is measured through profile deviation, lead deviation, surface roughness testing, and hardness testing according to ISO/DIN standards.
