Planetary gearing made of tungsten@ alloy - uses inclined gearing with special modulus and externally toothed hollow cylinders for planetary wheels to transfer great forces with high translation ratios.

摘要

The inclined gearing has a modulus of less than 1, pref. less than 0.7, and an overlap of at least 4. The approx. same tooth width of the first and second hollow wheel (5,6) corresponds at least to about 35 times, pref. 40 to 45 times, the value of the selected modulus. The planetary wheels (4) are externally toothed hollow cylinders which are installed tensioned radially elastically opposite the counter gearwheels (3,5,6). The width of the hollow cylinders corresponds approx. to the sum of the widths of the first and second hollow wheels (5,6). The drive and driven shafts (1,2) are each hollow shafts with the driven shaft inside the drive shaft. USE/ADVANTAGE - Extremely small planetary gearing structure allowing high deg. of speed redn. and low rate of wear with high operating loads.
