Calculation of Pins

Figure$-1\mathrm{.}2$ shows the connection of a gear wheel to the shaft with a radial pin. Under the influence of the torque Ma transmit

by the connection, the pin is forced to be cut, and the bearing surfaces of the pin and the shaft and hub are forced to be crus

Accordingly, the tangential force that forces the pin to $=\frac{F_t}{2\frac{d_p^2}{4}}=\frac{4M_d}{*d_p^2*d}{}_{em}$

It is written as $.$

The surface pressure between the pin and the shaft is maximum at the outer edge of the shaft and zero at the center. Figure$-1\mathrm{.}2.$ If a

linear change is accepted for surface pressure;

$P_{\text{m}\text{a}\text{x}}=3*\frac{F_t}{d*d_p}=\frac{6*M_d}{d^2*d_p}{P}_{mm}$ HOW CAN PMAX FORMULA FIND?
