Mechanical Power Transmission

MIT 213

Course Description

Prerequisites: Prerequisites: DRF 121, MS 113 or MS 114, and MT 221.

Develops skills in designing and specifying mechanical power transmission components for use in a product or process. Uses mathematical skills to design parts, calculate design requirements, specify commercial components and design the layout of the mechanical power drive train. Verifies that the assembly meets all specifications and quality requirements. Develops a Bill of Materials for the mechanical power transmission components. Uses presentation skills to demonstrate how the components were designed and specified. Credit may be earned in MFG 213 or MIT 213 but not in both. (45-0)

Outcomes and Objectives

Demonstrate the ability to design and specify a mechanical power transmission drive.

Objectives:

• Identify the components required for a solution to a drive system for a product or process.
• Determine the output torque and speed required in a given product or process.
• Select the type of drive components and co-requisite space available for the drive system as well as providing for environmental conditions encountered by the drive system.
• Select the material the drive system will be made of based on design and environmental requirements.
• Verify the design meets all applicable regulations. This would include all governmental regulations, primarily OSHA requirements.
• Demonstrate the ability to identify torque and speed requirements by doing the correct calculations using appropriate mathematical tools.
• Provide for system failure when verifying the design.

Develop a sequence of drive components based on available commercial components.

Objectives:

• Produce a preliminary sketch of the drive system.
• Design the low speed output shafting if required.
• Calculate the required torque and speed of the components.
• Design the low speed intermediate shafting if required.
• Select the drive components such as gear reducer, chain drive, v-belt drive, coupling systems and electric motor.
• Produce a final sketch of the drive system based upon the space required by the system including center distances and any take-up mechanism needed for adjustments.

Calculate and specify individual components parts of the final drive system.

Objectives:

• Select the individual commercial components based upon calculations of torque and speed required.
• Arrange the components and layout the components mounting requirements.
• Calculate any low speed shafting required using stress design or deflection design techniques.
• Select the drive motor or primary mover required to provide the input horsepower and speed observing customary standards for the industry.
• Verify that the individual parts meet drive system specifications using measurement processes.

Assemble the drive components to meet the product or process requirements.

Objectives:

• Verify the center distances are correct.
• Verify the final drive meets functional and environment requirements.
• Develop a Bill of Materials for the drive system components.

Utilize catalogs of commercial components to analyze and interpret how the drive system meets the design intent product or process requirements.

Objectives:

• Use presentation skills to summarize the design intent and how the drive system meets the requirements.
• Identify and assess the reasoning and purpose of the drive system design and the logic for choosing the individual components.
• Summarize and present the complete drive system to a specific audience using written or oral communication.
