A Research and Comparative Analysis of the full Planet Engagement Planetary Gear Train

Static Load Sharing Analysis of a Full Pinion Engagement Planetary Gear Train Based on Statistical Simulation

“…The reason for this is the geometric configuration of the inner and outer planets, whereby for the planetary gear train presented in this paper, in the ideal case where there are no manufacturing and assembly errors, the outer pins are subject to bigger deformations than the inner pins. This phenomenon is discussed in [12] and means that in the practical gear trains design, (20) could be useful for dimensioning the planets' bearings and the pins. In order to expand its applicability and be used for the calculation of the mesh load factor K γ , which is specified in ISO 6336-1 [13], (20) must be complemented by an equation accounting for the aforementioned peculiarities.…”

“…where S =∑ 11 si , K 12 si , K 22 si -sun gear/inner planet mesh sub-matrices; K 11 ri , K 12 ri , K 22 ri -ring gear/outer planet mesh sub-matrices; K 11 ppi−n , K 12 ppi−n , K 22 ppi−n -inner planet/outer planet mesh sub-matrices; K 11 BCi , K 12 BCi , K 21 BCi , K 22 BCi -carrier/pinion support stiffness sub-matrices. The element meshing stiffness matrices can be defined as…”

The Influence of Planet Position on Axle Loads in Double Planet Planetary Gear Trains

“…The double line represents the summation shaft in Figure 3. A more detailed comparison between different planetary and power branching geartrain types can be found in [5].…”

“…Six test scenarios are considered in the study with different angles between the planet axles, as shown in Figure 4. A more detailed comparison between different planetary and power branching geartrain types can be found in [5].…”

Size and efficiency based comparison of kinematically equivalent two-carrier planetary gear trains

“…Planet carriers I and II are connected by this shaft passing through hollow sun gear II (5) connected to ring gear I (6). Ring gear I is supported by a large rolling bearing (7), and ring gear II ( 8) is permanently locked to the gear train casing (9).…”
