Content Inside :
• Power source (motor, engine, etc.) • Power required (P = torque × velocity) • Continuous or Intermittent Motion • Operating conditions (start, load duration) • Magnitude of speed (input or output) • Speed modification (output to input, constant or variable, linear or rotary). Constant Speed Mechanical Transmission Elements. Relative Shaft Position, Gear Design Issues. • Types of Gears: spur, helical, herringbone, internal, rack, bevel, and worm • Angular Velocity Ratio (gear ratio) • Power Requirements (speed and torque) • Gear Tooth Loads • Gear Tooth Stresses. Gear Terminology. Pitch Circle (radius or diameter). Circular Pitch. Number of Teeth. Pressure Angle. Face Width. Spur Gears: Force Analysis. • W is the resultant force • Wt and Wr are tangential and radial components • d is the pitch diameter • ? is the pressure angle • ? is the applied torque. Helical Gears: Force Analysis, Bevel Gears: Force Analysis. Worm Gears: Force Analysis. Stresses in Gears: Lewis Formula. Stresses in Gears: AGMA Formula. Power Screws. • Consists of a threaded shaft and nut • Used to convert rotary to linear motion • Can be designed for high precision • Often have multiple threads • Non back drivable.
