Abstract

PURPOSE:To reduce an operational noise of a gear, by forming a tooth surface of the spur gear to a constant sloped surface in the direction of tooth width and preventing backlash, caused between mutually meshing gears, and axial vibration. CONSTITUTION:A spur gear 1 is provided with many teeth 1a, 1b, 1c in the periphery, and its tooth surface is formed to a sloped surface in such a manner that area of each tooth part 1a... is increased to the direction of tooth width D from an upper surface to lower surface of the gear. A sloped angle of this sloped surface is formed to constant for the all parts. Such spur gear 1 is used to be meshed with a normal spur gear 5. At this time, since thrust force is always applied between each tooth part even without providing a leaf spring or the like in a shaft of the gears 1, 5, vibration axially of the gears 1, 5 can be suppressed. Further a gap is never caused in a teeth meshing contact part of the both gears 1, 5, and backlash can be prevented.
