Today, various types of planetary gearboxes are increasingly being used in the hybridization of drive trains. Since the KISSsoft Release 2019, it is now possible to calculate double planetary stages (module ZA9). Due to their two intermeshing planets, double planetary stages achieve a subsequent reversal of the direction of rotation between the two central gears. The application in speed ranges of 7000-20000 rpm requires an exact analysis of the teeth with regard to noise as well as an evaluation of the planetary bearings concerning their service life.
The engineer can first calculate the strength of all gears and check the geometric assembly situation of the planets. Subsequently, all centre distances can be varied in the fine sizing of the double planetary stage and the influences of the meshing forces on the bearings can be compared from all possible solutions. At the same time, the minimum bearing diameters of the planetary gears and the largest possible installation space for the ring gear can be defined.
Finally, the planetary stage can also be displayed in a 3D graphic for a visual check.
Are you planning a visit to this year's MPT in Detroit, Michigan? The Motion + Power Technology Expo will take place from October 15 to October 17, 2019 and offers the opportunity to meet leading manufacturers, buyers and experts from the mechanical, electrical and fluid power industries. Our holding company, the Gleason Corporation, will also be attending this year and we look forward to accompanying them. Visit us at booth 3400 for a personal meeting.
