| Summary: | <p>The planetary gear system consists of several concentric single
stage face gears symmetrically meshing with multiple cylindrical gears that
as the core component of planetary multistage face gears transmission device
(PMFGTD), which is the key to realizing shifting and principle innovation
that able to flexibly extend the speed ratio region of single stage face
gear. The speed ratio distribution mechanism is directly related to the
feasibility of the design scheme. The stability, reliability and loading
capacity of each power split branch affect the performance of the whole
system directly. For the requirements of maximizing drive efficiency and
optimizing drive performance under different conditions, this study analyzes
the gear matching relationship and driving characteristics by using
numerical calculation method basing on the PMFGTD structural
characteristics, and calculates the corresponding transmission ratio value.
According to the torque equilibrium equation, the torque relation and power
ratio relation of each component are established, and then the power
distribution relation between system components is calculated. The flow
characteristics of system input power and each branch output power under the
condition with or without meshing power loss are analyzed. The influence
relationship model of power split coefficient on drive efficiency is
established to calculate the corresponding rules, thus the dynamic
characteristics of PMFGTD on power split under various working conditions
are proved by experiments. The result provides reference for the
transmission ratio distribution and structure design of planetary multistage
face gears transmission.</p> |
