<p>The present invention relates to laundry treating machines with a driving system comprising a shaft and a hub spline coupled to each other. According to the invention, a laundry treating machine (1) with a driving system (5) comprises a shaft (6, 8, 10, 310) and a hub (7, 9, 11, 211, 411) having respective splined coupling portions (12, 312, 13, 213, 413) with alternated teeth (12a, 312a, 13a, 213a, 413a) and grooves (12b, 312b, 13b, 213b, 413b) adapted to mesh with each other, said splined coupling portions (12, 312, 13, 213, 413) comprising respective spline surfaces defined by ridges of the respective teeth (12a, 312a, 13a, 213a, 413a). The laundry treating machine (1) is characterised in that the spline surface on at least one of said shaft (6, 8, 10, 310) and hub (7, 9, 11, 211, 411) comprises a tapered portion (10b, 11b) interposed between adjacent cylindrical portions (10a, 10c, 11a, 11c).</p> |
