发明名称 IMPACT ABSORBING MECHANISM OF GEAR TRAIN
摘要 An impact absorbing mechanism for absorbing impact generated upon meshing of gears by starting or stopping an electric motor, for example, in a speed reduction gear train of a disk grinder, has the problem that its ease of manufacture and the durability are lowered because small elastic components are located between a driven gear and a driven shaft when an impact absorbing action occurs in the rotational direction in the related art. The present invention is aimed to improve the ease of manufacture and the durability of the impact absorbing mechanism. It is configured to absorb impact by displacing steel balls in a diameter expanding direction by relative rotation of a driven gear and a driven shaft due to rotational power generated upon meshing and by displacing an axial displacement member in an axial direction against an axial elastic member.
