Abstract


Gear motor shunt because of its simple installation and commissioning of shunt high accuracy and without load , and pressurized . Is widely used in metallurgy, water conservancy, construction machinery and other industries , but the accuracy of related products also meet the requirements . Synchronizer dynamic characteristics of the internal flow field to provide a theoretical basis , in order to further improve the precision of gear shunt shunt . From its dynamic characteristics of the internal flow field starting to take advantage of the software FLUENT its numerical simulation of internal flow field area . By setting different parameters of the structure , to identify the main factors affecting the shunt accuracy . First , imported gear motor shunt mapping , geometry modeling using the measured dimensions of the gear motor shunt . CAXA software to draw accurate involute gear , FLUENT preprocessor Gambit meshing gear motor inside the shunt flow field area . Due to the large number of grid parallel computing for solving the model , the use of multiple computers . Secondly , according to the actual conditions , set different speed , shell and addendum gap value , the differential pressure value ; introduction of the standard k-ε turbulence model , set the boundary conditions of the flow field analysis , the use of dynamic mesh , the model. Using FLUENT monitor the function set on the export flow detection . Traffic data detected using FLUENT software import EXCEL graphics processing and can get the gear motor shunt two export flow value . Finally, based on the results of the FLUENT simulation analysis based on the detection of data flow , as well as the inside of the gear motor shunt flow field . Synchronization error analysis according to the different parameters of the detected flow rate value , and to analyze the obtained results , given in the case of not considered end leakage , gear motor shunt under different loads , the different speed the different tooth top and the housing gap value diversion accuracy and its variation .
