Double Arc Dynamic Performance Analysis Of Planetary Gear Reducer

Since2K-H (NGW) reducer with small, simple structure, high efficiency is widely used in mechanical transmission. However, coal, petroleum, metallurgy and other traditional industries, due to work load under heavy load reducer, involute planetary gear reducer in the long application process, the emergence of the tooth surface gluing, planetary wheel bearing failure conditions, such as pitting, so reducer life is reduced. In order to meet reducer contact strength and service life requirements, Dalian Heavy Industry Group presented to the double arc gear planetary gear rotation to develop designs.Based on the original double arc gear planetary gear graphic design and structural design, the establishment of pan-reversing system dynamics model of the line, and the effect of system parameters on mechanical vibration; and create virtual prototype mechanical power learning simulation analysis, to provide a theoretical basis for the structural optimization and system vibration.For double arc gear planetary reducer paper mainly studied the following areas:①On double arc gear meshing characteristics were analyzed to determine the tooth surface equation and its basic parameters, to complete parts (gear shaft, housing, planet carrier, planet wheels, etc.) based on three-dimensional modeling on Pro/E; and virtual prototype assembly, provided the model for the mechanical dynamics simulation.②Establish a centralized quality translational kinetic law of planetary gear reducer levels-to reverse the model and solve the natural frequency of the system.③Using finite element analysis software ANSYA important component of the input shaft, planet carrier, arc gear etc. and constrained freedom modal modal analysis, provide the basis for dynamic performance optimization components, and analyze the number of pieces of gear on board a round hole the impact of intrinsic mode arc gear systems for the analysis of resonance problems provide the basis.④The three-dimensional model of Pro/E to establish the (simplified) into mechanical dynamics analysis software ADAMS, the dynamic analysis to get the main components of the angular velocity, angular acceleration, and gear contact between component in each direction along the axis of the proposed impact factors machine vibration.。...
