Unformatted text preview: ston diameter or cylinder bore in mm, p = Maximum intensity of pressure on the piston in N/mm2, W = Weight of the flywheel acting downwards in N, and T1 + T2 = Resultant belt tension or pull acting horizontally in N. We know that gas load on the piston, π 2 FP = × D × p 4 Due to this piston gas load (FP) acting horizontally, there will be two horizontal reactions H1and H2 at bearings 1 and 2 respectively, such that F ×a FP (a + b) ; and H2 = P b b Due to the weight of the flywheel (W) acting downwards, there will be two vertical reactions V1 and V2 at bearings l and 2 respectively, such that W . b1 W . b2 ; and V2 = V1 = b b Now due to the resultant belt tension (T1 + T2) acting horizontally, there will be two horizontal reactions H1′ and H2′ at bearings 1 and 2 respectively, such that (T + T2 ) b1 (T + T2 ) b2 H1′ = 1 ; and H2′ = 1 b b The various parts of the side crankshaft, when the crank is at dead centre, are now designed as discussed below: (a) Design of crankpin. The dimensions of the crankpin are obtained...
