To create well designed individual machine elements, and integrate them into a coordinated robust system that meets the customer’s needs
Machine elements in a sugarcane machine
Interfacing between Machine Elements
Mechanical Drive
Receives power from a rotating source and alters the speed of rotation
Power Equation:
Design of Power Transmission
Information needed
- Nature of driven machine
- Level of power to be transmitted
- Desired output speed
- Rotational speed of input
Steps involved
- Selecting suitable machine element
- Estimating satisfactory machine element size
- Evaluate machine element performance against requirements
- Iterating until performance meets requirements
Standardised machine elements
Standardisation promotes uniformity of practice and hence economies through use of stock parts for first installations or subsequent replacements.
- Belts, chains, bearings, screws, nuts & bolts
Customised machine elements
Belts, Chains & Gears
Most machine drives are based on these 3
