I don't know if I have to include the weight of a gear in order to proceed on computing the forces acting on the plane of line shaft. If I have to determine it, how do I calculate the weight of the gear (spur gear)?

I already looked up for the density of material for gear. But how can I calculate the volume? What is the formula?CWatters said:Perhaps approximate the gear to a cylinder. Calculate the volume, look up the density of the material it's made from. Bash the numbers into the calculator.
I found a formula for the volume of gear, that is (πD/4)*b(face width) which is similar to the formula for volume of cylinder.Dr.D said:Much depends upon how closely you want to approximate the volume and hence the mass. If a simple cylinder approximation is sufficient for your purposes, then that will be easy based on what you find on Google.
If the cross section is complicated, you may need to do a volume integration. If you can't do that in closed form, it is always possible to do a numerical integration. This will put to use what you learned in Integral Calculus.

I have no choice but to assume that the gear is flat and there is no hub or rim.Dr.D said:The formula you quoted will not do well at all for a gear of the sort shown in the attached figure.View attachment 221557
use solid work to get any weightanorlunda said:That depends on how accurate you need to be. We can't answer that question without a lot more specific detail.
How would you determine the weight of any object of any shape?
The weight of a gear can be calculated by first finding the volume of the gear using its dimensions (diameter and thickness) and then multiplying the volume by the density of the material. The formula for volume of a gear is V = π * (d/2)^2 * t, where d is the diameter and t is the thickness. The density of the material can be found online or in reference books.
In most cases, you can use the weight of a similar gear to estimate the weight of a different gear, as long as they have the same dimensions and are made of the same material. Keep in mind that small variations in dimensions or material composition can affect the weight, so it may not be an exact estimate.
The type of material used to make a gear can greatly affect its weight. For example, a gear made of steel will be heavier than a gear made of aluminum, even if they have the same dimensions. This is because steel is denser than aluminum.
The weight of gears is typically measured in either kilograms (kg) or pounds (lbs). Some industries may also use other units such as grams (g) or ounces (oz).
Yes, you can use a scale to measure the weight of a gear. However, keep in mind that the scale will only measure the weight of the gear as a whole and will not be able to determine the weight of individual components or parts of the gear.
