Use durable materials (Increase allowable bending stress at root). To encourage bending strength, values in the equation for allowable tangential force (7.1) should be set to The value of denominator should be small & The numerator should be large It should be set to more than 1.2 for safety considerations Pressure angle/ Profile shift coefficient / Tooth width The following is the equation for bending stress :Īffected Factors and other Specifications In this section, we briefly introduce the bending strength and the surface durability.īending Strength of Spur Gears and Helical Gears JGMA401-01Īs shown in the Figure.7.1, the tooth fillet breakage occurs at the root when applied force exceeds the limit. Gear designers decide specifications in accordance with factors like torque, rotation and expected lifetime. Strength of gears depends on the breakage durability or friction durability. Strength and Durability of Gears / The tooth is the most crucial element of gears.
