求翻译：齿根受拉侧的弯曲疲劳应力不超过齿轮的许用弯曲应力235MPa，即齿根实际所受的最大Mises等效应力小于235MPa；根据设计要求，齿宽系数取0.22～0.35。是什么意思？

Tension side of the tooth root bending fatigue stress does not exceed the allowable bending stress of gear 235MPa, which suffered the greatest actual tooth root Mises equivalent stress is less than 235MPa; according to design requirements, tooth width factor of 0.22 to 0.35.

According to the side of the tooth bending fatigue stress does not exceed the allowable bending stress 235 gears MPa dental roots, that is actually the biggest Mises edge effects, such as less than 235 MPa; according to the design requirements, tooth width factor from 0.22 to 0.35 .

The tooth root is pulled the side the bending gatigue stress not to surpass the gear permitting with bending stress 235MPa, namely the tooth root actual receives the biggest Mises equivalent stress is smaller than 235MPa; According to the design request, the tooth width coefficient takes 0.22~0.35.

Tensile lateral tooth root bending fatigue stress does not exceed the permissible bending stress of gears 235MPa, that is, root effects such as maximum Mises forces actual 235MPa; based on the design requirements, width coefficient of 0.22~0.35.

Tension side of the tooth root bending fatigue stress does not exceed the allowable bending stress of gear 235MPa, which suffered the greatest actual tooth root Mises equivalent stress is less than 235MPa; according to design requirements, tooth width factor of 0.22 to 0.35.
