MEC8029 : Design of Mechanical Power Transmissions
- Offered for Year: 2019/20
- Module Leader(s): Professor Brian Shaw
- Lecturer: Dr Robert Frazer, Dr Timothy Lisle
- Owning School: Engineering
- Teaching Location: Newcastle City Campus
|Semester 2 Credit Value:||20|
To teach how to design and use mechanical power transmission systems and equipment, especially rotary drive systems. The module aims to enable students to specify / select / design drive systems to link a variety of prime movers to a very wide variety of driven loads to a given performance specification. It also aims to teach the design of selected power transmission components, equipment and systems in detail and to apply the knowledge gained to the design of a mechanical power transmission.
Outline Of Syllabus
Drive systems are integral to most machines and products. This course deals with the systems and the detail engineering to design successful transmissions:
- Introduction to drive systems and components.
- Principles of drive system and component design/selection.
- Design of power transmission shaft/bearing/housing assemblies for ease of manufacture and assembly.
- Gear drives, gear types, main characteristics, geometry, materials and manufacturing routes.
- Design and analysis of spur and helical gears.
- Hydraulic drive systems.
- Selected electrical drive systems.
- Drive system matching and selection.
- Detail design of typical mechanical power transmissions.
- Includes assignments to design/specify mechanical power transmissions in detail.

Teaching Rationale And Relationship
The lectures and course hand-outs introduce the topics and provide a firm foundation for the subject.
The machinery “tour” and hands-on exercises allow students to see many types of drive system design and experience several drive systems operating.
The gear software is used during the course and represents the industry standard transmission design software and allows selection of optimal gear designs.
The tutorial classes allow students to handle real mechanical components, view operating machinery and try out both design and analysis techniques under supervision.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The time limited assignment ensures appropriate incentive to understand and deliver functional detail designs for a simple mechanical power transmission.
The gearbox assignment, backed up by tutorials, applies the taught material and leads the students to a greater depth of understanding of the detail design of components and/or selection & matching of drive systems.
The unseen examination tests understanding of the lectured material using both normal exam questions and design orientated tasks.
The output of the gearbox assignment includes appropriate designs / system diagrams, calculations and evidence of appropriate decision making, all presented in a log book format.
For the purposes of professional body accreditation, in order to obtain a passing mark overall for this module (50%) at the first attempt the minimum acceptable mark for each of the assessment items specified below shall be 35%, with the maximum possible module overall mark where this is not the case being restricted to 40% (Undergraduate Progress Regulations):
(1) 70% Exam
(2) 30% Assignments
