Stiffness Analyses And Measurements Of Coupling And Rolling Bearing

Rolling bearings and couplings as support and drive components, is an important part of rotating machinery rotor system. Cylindrical roller bearing because of its simple structure, low cost, suitable for high speed and can withstand high radial load, and widely used;gear coupling of tooth structure can transfer bigger torque, and the ability to allow in the presence of certain axial, radial and angular deviation is transmission torque, so the tooth structure has also been widely used in high speed rotating machinery.Based on the cylindrical roller bearing and gear coupling as the research object, has carried on the stiffness characteristic of analytical and finite element simulation analysis, and design the static load of cylindrical roller bearing and gear coupling device,completed the stiffness test research. For roller bearing and gear coupling analysis of the design, manufacture, use and provides a certain basis.This article main research work is as follows:(1) set of gear coupling is analyzed the mechanical model of single tooth and the whole, the 5 degree of freedom analytical stiffness model was established.(2) based on ANSYS software, considering the contact nonlinear problems, such as, set up under the bending load of gear coupling simulation model. Under the action of bending load are analyzed in different set of tooth coupling stiffness properties change rule.(3) designing the 3 sets of gear coupling. According to the design of the gear coupling, design, processing and set up the coupling static load test-bed. Completed set of tooth coupling static stiffness test.(4) based on the ANSYS analysis software, according to the mechanics model of cylindrical roller bearing for N1007 cylindrical roller bearing, the simulation model is established. Finite element analysis of the model, get the stiffness of the model.(5) in view of the N1007 cylindrical roller bearings, according to gear coupling static load test to be modified. Completed the static load of cylindrical roller bearing stiffness test. Was obtained under the condition of the bearing test of rigidity change rule.
