Unit Code: PME441

Unit Name: Power Transmission

Description: The purpose of this unit is to enable the development of elementary knowledge and skills required for maintenance of Power Transmission Drives. This course offers the development of skills in servicing, fitting, aligning, assembling and maintaining of machines equipped with gears, belt drives, brakes, chain devices, clutches and couplings. Also covered in this unit are the practical and calculation of Chain velocity ratios, Chain speed ratios, Chain tensions, Chain lengths, Chain alignments, Gear velocity ratios, Gear speed ratios, Gear meshing, Gear types, and Gear alignments.

Learning Target Outcomes: On successful completion of this course, you should be able to: 1. Use annotated illustrations to demonstrate power transmission units used in modern engineering such as gears, belt drives, brakes, chain devices, clutches and couplings. 2. Calculate Belt velocity ratios, Belt speed ratios, Belt tensions, Belt lengths, and Belt alignments, Calculate Chain velocity ratios, Chain speed ratios, Chain tensions, Chain lengths, and Chain alignments, Calculate Gear velocity ratios, Gear speed ratios, Gear meshing, Gear types, and Gear alignments. 3. Select drive specifications from catalogues using above units for various applications. 4. Identify types of deterioration in power transmission devices.
