Investigation of the energy effectiveness of multistage differential gears when the speed is changed by the carrier

“…The analysis of the problem shows that it is more rational to use differential gears, which are widely described in classical literature for example, [15][16][17], that consider the structure, synthesis and analysis, kinematic and power issues of planetary type gear transmissions. Periodical technical literature [18][19][20][21] has proposed a new stepless method for speed changes control by the singlestage differential gears with closed circuit hydrosystems and its kinematics research. In [18], the current state of the methods and devices for the speed change process controlling in technology has been analyzed, a new method of continuously variable speed changes control using differential gear transmissions with a closed circuit hydrosystems has been proposed, and a new classification given.…”

“…The driving link of this multistage differential gear is the first-stage sun gear 1 (1) , and the driven link is the ring gear 3 (n) of the n-th stage. Expressions of the relationship between the speeds of the driven link (the ring gear 3 (n) ) ω out and the driving link (sun gear 1 (1) ) ω in have been obtained in [21].…”

“…The driving link of this two-stage differential gear is the first-stage sun gear 1 (1) , and the driven link is the second-stage ring gear 3 (2) . Relationship between the speeds of the driven link (the ring gear 3 (2) ) ω out and the driving link (sun gear 1 (1) ) ω in have been obtained in [21]. Here, ω 4(1) and ω 4(2)velocities of the carriers, respectively, of the first 4 (1) and the second 4 (2) stages, which vary due to the closed circuit hydrosystems 6 (1) and 6 (2) .…”

Theoretical foundations for the development of experimental equipment for determining the load capacity of speed change devices

“…Devices for speed changes control by epicyclic gear trains with closed circuit hydrosystems were first described in [9]. Theoretical scientific data about them was reported at scientific and technical conferences, symposia [10][11][12][13][14][15], and others, where questions aroused about their kinematic possibilities, which were further considered in works [16][17][18][19][20][21][22][23][24], performance efficiency coefficients [25]- [27]. Moreover, work [28] is devoted to 3D modeling of such devices.…”
