Internal Marks: 30 L T P
External Marks: 20 0 0 2
Total Marks: 50
1. Review of principles of retainment, alignment and assembly, of various
components of machines, various types of oil seals: friction lock and its
applications in reciprocating cam-followers, assembly and link motions.
2. Study the layout of some existing transmission system design and suggest a
new conceptual design by removing the shortcomings of the existing design
3. Find an assembly containing the belt and pulley mechanism and do the
complete design calculations and then justify the existing design.
4. Calculation of the velocity ratios required in a gear box and then design the
gearbox in practical application (gearbox application must involve different
types of gears like bevel, spur and helical gears)
5. Find a transmission system involving the worm an worm wheel and then find
out the inputs required for its design and justify the design.
6. The gearbox design in the exp no. 5, Design the shafts required to support
the assembly and design it for manufacturing and assembly.(with actual
calculations of the loads and the end conditions)
7. For a press of your machine shop, study the process and suggest the design
parameters of the flywheel required. Justify the design if flywheel is already
there.
8. Design springs for practical application for the given conditions and
constraints and find its practical availability.
9. Select a mechanical component or system, convert its design procedure into
an algorithm and write a code for its design or with the help of an application
software.
