Asstem of Corrected Spur Gears.
Journal of the Society of Mechanical Engineers, 1945 小齒車及び大齒車の曲げに對する強度を等しくすれば, この一對の齒車は動力傳逹用として最も望ましいものとなる.斯る條件を滿足する如く轉位係數を選擇する方法として, 齒形の隅肉を形成する二つのトロコイド曲線間の最短距離Sを, 同一材料から成る齒車對では相等しくなる如く, 又異なる材料の齒車對ではS2が材料の縱彈性率に反比例する如くとることを提案してある.Sの値が異なれば, 同一齒數の一對の齒車に對し, 種々異なる性質のものが出來る譯であるから, 斯る轉位齒車群の噛合性能圖を作製し, 中心距離又は使用目的により轉位係數の最後的決定をなす轉位平齒車の一方式に就て述べてある.尚壓力角αc=14°30′及びαc=20°の標準ラック型カッタに對し, 轉位係數の選擇に必要な圖表及び計算例をも示してある.

Load Contact Analysis and Strength Calculation of Spur Gear
Jixie chuandong, 2016 Through tooth contact analysis（ TCA） and loaded tooth contact analysis（ LTCA）,the meshing process of spur gear pair is simulated. Based on this,combining with the elasticity theory,the contact stress on each meshing point are calculated.

Research on Loaded Transmission Error of Internal Short Tooth Spur Gears
Jixie chuandong, 2023 Loaded transmission error is an important parameter in evaluating the meshing performance of gears. The smaller the fluctuant amplitude of the loaded transmission error is, the better the meshing performance is.

Gear Tooth Stress of an End-Relieved Spur Gear
Bulletin of JSME, 1966 In the nose-suspended type traction gears, the angle between the projected lines of axes of pinion and gear on pitch plane often becomes equal to about 10' and end tooth bearing happens, leading to tooth failures. In JNR, as the countermeasure for these failures, heavily crowned gears are used for nose-suspended type traction gears.
