Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

Q1) The V thread of a screw jack has a single start with out side diameter 40 mm and 6 mm pitch. The angle of V is 55° and the load is carried on a swivel head of mean diameter 60 mm. the coefficient of friction between the nut and screw is 0.16 and that between the swivel head and the spindle is 0.1. Calculate the load required to be applied at the end of two levers each of effective length of 500 mm to raise an axial load of 1 KN and the efficiency of the lifting.

1. A single-threaded 25-mm power screw is 25-mm in diameter with a pitch of 5mm. A vertical load on the screw reaches a maximum of 5 kN. The co-efficients of friction are 0.06 for the collar and 0.09 for the threads. The frictional diameter of the collar is 45-mm. Find the overall efficiency and the torque to "raise" and “lower" the load.
4. A small race car has an aluminum hub (shown in red). The drive axle is press-fit into the hub, resulting in compressive pressure and torsional friction as shown below when the wheel is powered. Assuming a coefficient of static friction of 0.3 and a shear yield strength of 30 ksi for the shaft, determine the maximum allowed contact pressure, p (in psi). In other words, how much contact pressure (and resulting torque) would cause yielding of the shaft? Given: d=0.75in, w=1.5in f: Friction force per unit area p: Normal force per unit area

The permissible tensile stress in the bolt is 70 MPa and the permissible crushing stress in the key is 90 MPa. The coeffi cient of friction between the muff of the CI and the shaft of steel is 0.20.
Q3) A single block brake, as shown in figure, has the drum diameter 250 mm. The angle of contact is 90° and the coefficient of friction between the drum and the lining is 0.35. The other dimensions are as follows: a = 200 mm, 1 = 400 mm and b = 100 mm. If the torque transmitted by the brake is 70 N-m, find the force F required to operate the brake.
