摘要： PROBLEM TO BE SOLVED: To efficiently manufacture a bevel gear of high finished profile irregularity while considerably improving a tool life in machining the bevel gear using an annular rack-shaped machining tool provided with a CBN (cubic boron nitride) electrodeposited abrasive grain layer at the cutting edge.
SOLUTION: Finishing of one tooth space and rough machining of an adjacent tooth space is performed by one-time indexing, using the bevel gear machining tool constituted to mount a rough machining electrodeposited grinding wheel outside or inside a finish machining electrodeposited grinding wheel. A machining time is thereby shortened, or machining accuracy is improved, and the tool life can be considerably improved.

摘要翻译：要解决的问题：为了有效地制造具有高成型轮廓不规则性的锥齿轮，同时显着提高了使用设置有CBN（立方氮化硼）电沉积磨料颗粒的环形齿条加工工具加工锥齿轮的刀具寿命在切割边缘。
解决方案：使用一个锥齿轮加工工具，通过一次性分度进行一个齿隙的精加工和相邻齿隙的粗加工，该锥齿轮加工工具用于将粗加工电沉积砂轮安装在精加工电沉积砂轮的外侧或内部。由此缩短了加工时间，提高了加工精度，并且可以显着地提高刀具寿命。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To generate a high reduction ratio hypoid gear by modifying a Gleason type bevel gear cutting machine. SOLUTION: A detachable gear 15 is arranged in a roll change gear train 7, and a work spindle 5 and a cradle 6 are disconnected from a cam 3. An input gear 21 in a ratio change gear train 9 is connected to a generating motor 10 via a speed change gear train 22. The work spindle 5 and the cradle 6 are driven by the generating motor 10 independent of a driving motor 4. Limit switches are provided so as to engage with a gear 17 of the roll change gear train 7. Rotational directions of the generating motor 10 are controlled by timing signals output from the limit switches.

摘要： PROBLEM TO BE SOLVED: To prevent tooth-hitting sound from being generated on a hypoid gear mechanism part due to the influence of input from tires, when a suitable backlash is set. SOLUTION: An inner gear 120 is elastically supported, in relation to an outer gear 110 by a plate spring body 121. Ring springs 131, 132 are provided to increase elastic support force, and therefore, oscillation of the inner gear 120 generated along a direction approximately perpendicular to the axis for linking the meshing part of a hypoid pinion gear 200 to the rotational center of the outer gear 120 is restrained.
