摘要： A method of manufacturing a helical gear, includes a gear cutting process for forming a roughly-processed gear by applying a gear cutting to an outer circumferential surface of a blank, and a tooth surface forming process for forming a tooth surface by pressing a rolling die against a roughly-processed tooth surface of the roughly-processed gear, wherein a length of a portion of the roughly-processed tooth surface, to which a plastic deformation is applied by the rolling die, in a face width direction is formed to be shorter than a length of a face width of the roughly-processed tooth surface.

摘要： When a count value concerning with the travel of the vehicle in a two-wheel drive state reaches or exceeds a predetermined value, the state of drive in a transfer is temporarily switched to a four-wheel drive state by connecting a synchromesh mechanism while keeping a mesh clutch disconnected, so that rotary members that do not rotate during the two-wheel drive state, such as a second output shaft, are temporarily rotated. Thus, the rotary members are restrained from remaining in contact at fixed portions and therefore being partially worn. Besides, there is no need to provide a mechanism for temporarily rotating the rotary members, such as the second output shaft, separately from the synchromesh mechanism that is normally provided for the four-wheel drive travel in the related art. Therefore, it is possible to improve durability without involving cost increase, space efficiency deterioration, etc.
摘要翻译：当与两轮驱动状态下的车辆的行驶有关的计数值达到或超过预定值时，通过连续同步啮合机构将转印中的驱动状态暂时切换为四轮驱动状态，同时保持网状离合器断开，使得在两轮驱动状态期间不旋转的旋转构件（例如第二输出轴）暂时旋转。因此，旋转构件被限制在固定部分处保持接触，因此部分磨损。此外，不需要提供一种用于临时旋转诸如第二输出轴的旋转构件与现有技术中通常设置用于四轮驱动行程的同步啮合机构分离的机构。因此，可以提高耐久性而不涉及成本增加，空间效率劣化等。
