Figure 1 shows the drive shaft wheel connection of a light rail
vehicle. Wagon A
and B points are mounted on the shaft, and the weight of the wagon
affects the bearings equally.
The wheels are tapered with the pre-tension force created by the
bolt-nut connection to the shaft.
connected as a pass. The shaft receives from the gear connected to
point C as a tight fit and it transfers the torque equally to the
wheels.
Force Fr acts in the vertical plane from the gear to the shaft and
Ft acts in the horizontal plane.
Given:
Wheel diameter: 800 mm Gear mean diameter: 400 mm
Shaft dimensions:
l= 1000 mm, ly=250 mm, do=120mm, d=130 mm, dc=160 mm, a=250 mm,
b=750 mm, c=650
mm, e=200 mm, r=6.5 mm
Shaft end bolt : M100
Forces:
Wagon weight per axle (Gv): 20 kN,
Gear torsional moment. 6000 Nm
Feminine forces. Ft: 15 kN Fr: 5.5 kN
Materials and coefficients of friction:
Shaft material: 50CrMo4
Gear hub material: 20MnCr5
Wheel material: 18CrNi8
Shaft-Gear hub friction coefficient: 0.2
Shaft-wheel hub friction coefficient: 0.2
Screw-nut friction case:.0.15
