Analysis and calculation of the multi-planetary line gearbox

transmission efficiency

¡¾Abstract¡¿ Planetary power shift transmission has: can be small module gear, parts by the

force balance and stability, small size, compact structure, structural rigidity, long life, high reliability control system, easy to control, higher efficiency of transmission form advantages. Are mainly used wheel loaders, bulldozers, scrapers, motor graders, and their technology is more mature. Efficiency is one of the most important parameters of a machine, this paper investigates the transmission efficiency of the transmission of multi-planetary line of great significance for later assist in the selection, design and improvement of the planetary transmission and thus improve the efficiency. This article omitted the hydraulic losses (oil and stir and splash loss), and consider only the gear meshing friction loss and the friction losses in the bearings, the use of the basic method - speed ratio method for the D6D transmission efficiency calculation and analysis, and based on VC + + 6.0, Delphi, VB6.0 planetary gearbox analysis system for computer-aided analysis.
