11.23 The gears shown in Figure P11.20 have a module of 5 mm,
tooth width of 15 mm,
and a 20° pressure angle. Determine
a. The allowable bending load, applying the Lewis equation and Kf =
1.5, for the
tooth of gear 3
b. The allowable load for wear, using the Buckingham equation, for
gears 3 and 4
c. The maximum tangential load that gear 3 can transmit
Design Decisions: All gears are made of cast steel (0.20% C
WQ&T, Table 11.3);
gears 2 and 3 are mounted on shaft B.
11.24 Reconsider Problem 11.23, but to find the allowable bending
load for gear 1, the
allowable bending load for gears 1 and 2, and the maximum
tangential load that the
gear 2 can transmit.

A pair of enclosed spur gears have z1 =20, z2 =80, m = 3 mm and face width factor of ?d =1.0. The pinion rotates at n1 =970 rpm. The allowable contact stress of the pinion and gear are [?H1] = 700 MPa, [?H2] = 500 MPa, respectively. The load factor is K =1.5, zone factor is ZH =2.5, elastic coefficient is ZE =189.8 MPa1/2. Determine the power that can be transmitted by tooth surface contact strength analysis.
In the figure below, a rotating shaft (for speed reducing gearbox) is subjected to radial forces at A= 400 lbr
In the figure below, a rotating shaft (for speed reducing gearbox) is subjected to radial forces at A= 400 lbr .and at C = 800 Ibr. These radial forces are caused by spur gears mounted to shaft (a result of the pressure angle of the teeth, 20 degrees) that mesh with 2 other spur gears, not shown. Also, The shaft transmits a constant torque of 11110 in-lbr (925 ft-lbr) due to the tangential force (Wt: transmitted load) at C of...
