  • Forging Reduction Ratio Upset Before Reducing Area

    Can anyone recommend any references (such as standards or ASM handbooks) that would clearly allow or disallow determining the reduction ratio this way? Example: Ingot size: 20" diameter Ingot upset to size: 24" diameter (for the whole length of the forging) Final Forging size: 10" diameter In this case, would the reduction ratio be (20^2)/(10^2) or (24^2)/(10^2)? RE: Forging Reduction Ratio

  • Gear ratios and compound gear ratios

    Determining compound gear ratios (multiple stages) Let's multiply both sides by 8, so our 1:12 ratio becomes 8:96. To get the reduction ratio for both gears, we want each gear ratio to be about the square root of 12, which is about 3.464. Now 8 * 3.464 is 27.7. So lets try 28 teeth for the intermediate gear. So we can write 8:28:96 or 8:28 and 28:96 We can divide the right side by 4, so weОнлайн-запрос
