Non-Coaxial 24-Speed Shaft-Planetary Gearbox

Abstract

The article presents the results of the analysis of existing designs of non-coaxial planetary gearboxes, their advantages and disadvantages. The invention is related to transport machinery area, transmission of transport vehicles, land transport systems, including motor vehicles, tractor-trailers, construction and road machines, tractors and ground-based equipment for special purposes. The design and kinematic scheme of a non-coaxial multiple-speed shaft-planetary gearbox, type 24R10, are presented. The work describes the operation of a non-coaxial multiple-speed shaft-planetary gearbox, type 24R10 (24 direct gears and 10 reverse gears), as well as gear ratios for each gear. A technical and economic assessment of the non-coaxial multiple-speed shaft-planetary gearbox, such as 24R10, is given. It is shown that the task is solved by compacting the layout of the multiple-speed gearbox and the planetary mechanism both in gear and summing modes, as the torque enters two links and is removed from the third one. The research proves that the design of a non-coaxial multiple-speed shaft-planetary gearbox, type 24R10, provides an improvement in the layout and operational characteristics of the gearbox and, accordingly, the operational capabilities of the vehicle.

Planetary Gearbox Design and Development using Additive Manufacturing

“…Although these trains are of great importance, they are also subject to a number of challenges, including vibration, frequency diagnosis, their motion, and so forth. (16)(17)(18)(19) The result is that geometrical real-time tests are difficult and cost a considerable amount of money. (20,21) Yet, it would be possible to fabricate planetary gear trains in 3D for testing at a low cost.…”
