Angle between Two Arms of Rocker Arm

LaTeX Go Angle Between Rocker Arms = pi-arccos(-(Total Force on Rocker Arm of Exhaust Valve^2+Force on Roller Pin^2-Force at Fulcrum Pin^2)/(2*Total Force on Rocker Arm of Exhaust Valve*Force on Roller Pin))

Reaction at Fulcrum Pin of Rocker Arm

LaTeX Go Force at Fulcrum Pin = sqrt(Total Force on Rocker Arm of Exhaust Valve^2+Force on Roller Pin^2-2*Force on Roller Pin*Total Force on Rocker Arm of Exhaust Valve*cos(Angle Between Rocker Arms))

Reaction at Fulcrum Pin of Rocker Arm for Equal Arm Lengths

LaTeX Go Force at Fulcrum Pin = Total Force on Rocker Arm of Exhaust Valve*sqrt(2*(1-cos(Angle Between Rocker Arms)))

Bearing Pressure at Fulcrum Pin of Rocker Arm

LaTeX Go Bearing Pressure for Fulcrum Pin = (Force at Fulcrum Pin)/(Diameter of Fulcrum Pin*Length of Fulcrum Pin)

Outside Diameter of Boss of Rocker Arm at Fulcrum Pin Formula

LaTeX Go

Outside Diameter of Boss of Rocker Arm = 2*Diameter of Fulcrum Pin
D_o = 2*d₁

Design of cross section of rocker arm

The arm is subjected to bending moment under the action of force Pe. The bending moment is maximum at the centre of the pivot. In general, the central section passing through the fulcrum pin is sufficiently strong to withstand the bending moment. Therefore, we will consider the cross-section of the arm near the boss of the fulcrum pin. The outside diameter of the boss of the rocker arm at the fulcrum pin is twice the diameter of the fulcrum pin.
