FNITE ELEMENT ANALYSIS OF INNER TEETH CONTACT OF RING PLATE GEAR UNDER CONSIDERING ERROR CONDITION

摘要

According to the feature of inner teeth contact transmission whose gears have less difference of teeth, the error types of gear machining and installation are analyzed. Considering manufacturing errors and assembling influence, analyze the transmission error of inner teeth meshing, establish finite element model of inner teeth contact of plate, which take error into account. And carry out finite element analysis under rating power by using the established models, therefore, discuss the influence of error and variable load on contacting teeth, and point out vibration factors caused by im-balanced load. By investigation of design, kinematics analysis and fault diagnosis of the novel type DRR, the writer puts forward the efficient solution or theory basis for the existing problem in the reducer, such as dynamic imbalance, intense vibration and noise, draw-off heat, etc.
