Job ID: 31229304

Budget: €30 – €250 EUR

Task1:
The difference between shoulders of an input shaft in a gearbox is 5 mm. The technology allows fillet radius of 3 mm. Whenthe shaft is rotating, the shoulder fillet is loaded with a bending moment Mo = 100 Nm and a steady torsion moment Mk of740 Nm. The used heat-treated carbon steel shaft with catalogue values

p = 620 MPa,
p = 450 MPa,
k = 420 MPa,
k =240 MPa,
co = 275 MPa,
ck = 155 MPa.

Question: create a hand sketch that indicates the situation
Task2: The input shaft of gearbox with is assembled with a helical pinion. The shaft is supported by the means of a pair of radial single-row ball bearing. A spline for the feather key is machined into the cylindrical input shaft for coupling an interacting part.
Question: create a hand sketch where you respect the nature of ball rolling bearings and the way you secure them.
