| dc.description.abstract | This report outlines the design of a shaftless screw conveyor and the development of a testing methodology for Sperling Industries Ltd. as part of the University of Manitoba's MECH4860 Engineering Design course. Sperling Industries Ltd. is a Manitoba-based company that offers engineering and metal fabrication services. Sperling proposed this project to become more competitive in manufacturing shaftless screw conveyors. A shaftless screw conveyor is a conveyor that moves material by the turning action of a screw-like surface called a flighting. Shaftless screw conveyors are unique because a central shaft does not support the flighting. Instead, the flighting rests on a wearable liner that sits on the base of the trough enclosing the conveyor. The student team had to develop a prototype shaftless screw conveyor that the Sperling engineering team could use for testing. The manufacturing of the prototype must cost between $18,000-$22,000, and the design for the prototype was to be submitted to the client as a CAD assembly of the entire design along with a testing methodology. The testing methodology describes what should be measured and how it should be measured. It also includes a step-by-step procedure on using the conveyor for testing and will be modifiable to suit the client's future needs. The rest of the report focuses on the process followed by the student team including the definition of the project, the development of concepts used in the design, the analyses completed to create the design, and the final design proposed by the team. The final design is a shaftless screw conveyor powered by a 2 HP motor with a gearbox and VFD used to control its speed. The conveyor is expected to move 300 ft3/hr of material when loaded to the maximum capacity. Notable features of the final design include a shear pin design on the input shaft connection, which acts as a fail-safe when the conveyor is overloaded, custom-made liner stops to hold the wearable trough-liner in position, bearing supports for the flighting on both ends of the conveyor, and a unique connection plate that allows the motor to be connected from either end of the conveyor. The suggested testing methodology focused on testing for properties such as the thrust generated when the conveyor is running, the motor's torque output, and the horizontal deformation of the flighting. The total cost of the design is $19,041.16. This includes the material cost, the labor cost incurred by the client, the cost of outsourced components, and the cost of the sensors required for testing. This total cost falls under the budget set by the client, and the prototype meets the revised objectives set by the client | en_US |
