The intermediate shaft of a two-stage gearbox is given in the figure. P = 4 kW power is transmitted at n = 150 rpm with the help of two helical gears on the shaft. The forces acting on the gears are given as Ft1 = 5092 N, Fr1 = 1972 N, Fa1 = 1853 N, Ft2 = 2546 N, Fr2 = 986 N, Fa2 = 926 N. Diameter of small helical gear d1 = 100 mm, large the diameter of the gear is d2 = 200 mm. Shaft material yield strength 335 MPa, tensile strength 600 MPa, Kç = 1.95, ka = 0.895, kb = 0.90 and safety coefficient = 1.4

Question

The intermediate shaft of a two-stage gearbox is given in the figure. P = 4 kW power is transmitted at n = 150 rpm with the help of two helical gears on the shaft.
The forces acting on the gears are given as Ft1 = 5092 N, Fr1 = 1972 N, Fa1 = 1853 N, Ft2 = 2546 N, Fr2 = 986 N, Fa2 = 926 N. Diameter of small helical gear d1 = 100 mm, large
the diameter of the gear is d2 = 200 mm. Shaft material yield strength 335 MPa, tensile strength 600 MPa, Kç = 1.95, ka = 0.895, kb = 0.90 and safety coefficient = 1.4
