BBAによる一段歯車装置の振動応答解析 : 歯車対のかみあいを考慮した伝達関数の評価

抄録

Transfer function of a single stage gearbox is presented to simulate the transmission of gear-mesh induced vibration to the housing. Transfer function of a substructure composed of a pair of spur gears, shafts supported by ball bearings is introduced considering the gear mesh. The substructure is then assembled with a housing, whose transfer characteristics is already known, by BBA. Vibration transmissibility defined by the ratio of the acceleration of any point on the housing to the circumferential acceleration of one of gear bodies is introduced and response of the box due to actual gear acceleration obtained by experiment is calculated. The calculations are compared with the experimental response showing pretty good agreement. The method may be useful to predict the structure borne noise caused by gear mesh.
