Precision controlled Adaptive Rack

The rack is a key transmission part for converting rotational and linear motion, constructing an efficient power transmission chain through precise meshing with gears, and has three core highlights. In terms of transmission stability, it adopts an optimized involute tooth profile design, and the meshing process is surface-contact progressive transmission, with the overlap degree increased to more than 2.0, and the impact vibration reduced by 35% compared with the traditional structure, realizing low-noise and stable linear drive. In terms of precision performance, relying on CNC forming grinding + full-process precision detection technology, the cumulative pitch error is strictly controlled within 0.018mm/m, and the tooth surface roughness reaches Ra0.32μm, meeting the positioning accuracy requirements of precision equipment. The linear adaptability is outstanding, supporting modular tooth segment splicing design, which can be flexibly combined according to the equipment stroke, the…
