My T.E. Mechanical AutoCAD drawings

I made these drawing using AutoCAD for my Third Year undergraduate Mechanical Engineering course. This year we first had to design the components, determine safe dimensions & then use it to draw suitable assembly & detail drawings. Quite unlike last year when we simply put in value into the empirical values represented in terms of proportions w.r.t. the shaft diameter.

Semester 1: Design of Machine Elements [DME]

Have not kept last years journals. So have absolutely no idea what the problem statement was. :)

Semester 2: Transmission System Design [TSD]

We had to design a gearbox to operate a sluice gate. I found only the Assembly drawings. Did not keep a copy of the Assembly drawings which were prepared by another classmate in my Design group. Not quite sure how the BOM got misaligned – probably a result of importing AutoCAD drawings into Solid Edge 2D.

Problem Statement: Design a Gearbox to operate a 20 KN Sluice Gate with Power Screw rotating at 10 rpm.
