Summary of Content

The aim of this module is to develop further the student's ability to synthesise and analyse engineering systems through component design.


The teaching syllabus will cover the following areas: The module is a mix of theoretical underpinning, use of codes of practice and design guides and studies. The application of BS 5950 to the design of connections by both welding and bolting arrangements including in-plane torsion and out-of-plane bending loading conditions. Basic geometry of spur and helical gears. The design rules for spur and helical gears and the generation of tooth forces. The transmission of tooth forces and resultant forces at shaft bearings. Typical gear/shaft assemblies, the methods of locating and securing gear on shaft. General review of bearing types, the design parameters involved in the design and selection of ball and roller bearings. The various types of lubrication and the prevention of leakage, shaft oil sealing design. Assembling and securing bearings on shafts. The selection of bearings using manufacturers' data/catalogues. Terms used in design of power screws, calculation of torque required to lift and lower the load, efficiency of power screws, conditions for overhauling and self-locking. Spring design including discussion of types of springs, materials and standard wire dimensions. Buckling of springs and appropriate design methods. Appropriate theory for close-coiled and open-coiled of circular cross-section helical springs.

Learning Outcomes

On successful completion of this module the student should be able to:1. Design bolted and welded connections for components and parts, conforming to BS 5950 (AM1)2. Solve design problems related to gear tooth force, generated in shaft supported bearings. (AM1, AM5)3. Select ball and roller bearings for specific applications (AM5)4. Apply appropriate techniques for design of power screw systems (AM5).5. Design open and close-coiled helical springs (AM1, AM5).

Teaching / Learning Strategy

The strategy of teaching is to deliver theory and application examples through formal lectures. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
