- 摘要:
- An epicycloidal gearing (1; 20) particularly fit to be employed in rolling up devices (A) for curtains, shutters and alike comprising: a crown wheel (2; 2') with inner toothing; a pinion gear (3; 3') placed coaxial inside of said crown wheel (2; 2') and three planetary gears (4, 5, 6; 4', 5', 6') simultaneously meshed with said crown (2; 2') and with said pinion (3, 3'). Each of said planetary gear defines a respective radial direction (X, Y, Z) of alignment of its own center of rotation (4b, 5b, 6b) with the center of rotation (7) of said pinion (3, 3') and of said crown (2; 2'), characterized in that said pinion (3, 3'), said crown (2; 2') and said planetary gears (4, 5, 6; 4', 5', 6') are equipped with corrected contour teeth (3a, 2a, 4a, 5a, 6a), whose sum is a number not divisible by three. <IMAGE>
