Transverse toothed planetary gear for height adjustment of belt in vehicle, has sun wheel, planetary wheels and hollow wheel formed from plastic, where planetary wheels have teeth width that corresponds to value of their diameter

摘要

The gear has two planetary wheels (4) staying in contact with a sun wheel (2) and held by a pinion cage (3). An inner toothed hollow wheel (5) stays in contact with the planetary wheels. The sun wheel, planetary wheels and the hollow wheel are formed from plastic and are formed pairwisely from polyoxymethylene and polybutylene terephthalate. The planetary wheels have a module of approximately 0.1 millimeter to 0.6 millimeter, where the wheels stay in contact with each other. The planetary wheels have teeth width (b), which corresponds to the value of their diameter.
