An input shaft of a gearbox with motor power P = 7 kW and rotation number n = 1300 rpm. The diameter of an input shaft is d = 20 mm and its material is 16MnCr5. A force of F = 2800 N forces the shaft due to the operation of a gear wheel connected with a wedge on the input shaft. The distances of the gear from the bearings are given as L₁ = 40 mm and L2 = 60 mm. In the most dangerous section, you are required to check the strength according to the S = 3 safety factor. If the section is unsafe in terms of strength, what changes would you make in the design to make it safe? (The surface of the spindle is machined as fine chips, reliability poor Kg = 1.).

Question

An input shaft of a gearbox with motor power P = 7 kW and rotation number n = 1300 rpm. The diameter of an input shaft is d = 20 mm and its material is 16MnCr5. A force of F = 2800 N forces the shaft due to the operation of a gear wheel connected with a wedge on the input shaft. The distances of the gear from the bearings are given as L₁ = 40 mm and L2 = 60 mm. In the most dangerous section, you are required to check the strength according to the S = 3 safety factor. If the section is unsafe in terms of strength, what changes would you make in the design to make it safe? (The surface of the spindle is machined as fine chips, reliability poor Kg = 1.).

1. An input shaft of a gearbox with motor power P =7 kW and rotation number n = 1300 rpm. The diameter of an
input shaft is d = 20 mm and its material is 16MnCr5. A force of F = 2800 N forces the shaft due
to the operation of a gear wheel connected with a wedge on the input shaft. The distances of the gear from
the bearings are given as L, = 40 mm and L2 = 60 mm. In the most dangerous section, you are required to check
the strength according to the S = 3 safety factor. If the section is unsafe in terms of strength, what :
changes would you make in the design to make it safe? (The surface of the spindle is machined as fine
chips, reliability poor Kg = 1.).
