| description | PROBLEM TO BE SOLVED: To reduce propagation of vibration in a rotating direction produced in engagement, vibration (vibromotive force) in a translational direction around a gear, and vibration propagation exerting an influence on a peripheral portion, respectively, by setting axial displacement by inclination of a shaft of a driving helical gear, and a tooth surface deflection amount of a driven helical gear to be equal to each other in engagement of the cantilevered driving helical gear and the driven helical gear.SOLUTION: A helical gear drive transmission device includes: a driving helical gear; a driven helical gear driven while being engaged with the driving helical gear; a driving gear bearing portion rotatably and pivotally supporting a shaft portion of the driving helical gear; and a driven gear bearing portion rotatably and pivotally supporting a shaft portion of the driven helical gear. An axial position in starting the engagement of the driving helical gear is set to a side separating from the driving gear bearing portion, and axial displacement by inclination of a rotation shaft of the driving helical gear determined by load torque added to the driving helical gear, and bearing rigidity of the bearing portion of the driving helical gear, and a tooth surface deflection amount of the driven helical gear are made equal to each other.SELECTED DRAWING: Figure 2
