# how to find out ball mill rpm from motor and gear box output rpm

### How to calculate a gear ratio x-engineer

By input we understand the source of power in our case could be an electric motor. By output we mean where the power is delivered (e.g. hydraulic pump). The gear ratio i can be calculated in two ways as a ratio between the number of teeth of the output gear and the number of teeth of the input gear i=frac z_ OUT z_ IN Sep 13 2010 · Motorcycles run 24T #50 size sprockets way over 3000 rpm as high as 10 000 rpm and more for short periods. Is your question about chain mfgrs. recommendations or about chain life or catastrophic failure Very high speeds make the chain hot requiring an oil bath for long life but 3000 is not what I d call very high speed.

### 4 Easy Ways to Determine Gear Ratio (with Pictures)

Dec 07 2020 · Using the idea of gear ratios it s easy to figure out how quickly a driven gear is rotating based on the "input" speed of the drive gear. To start find the rotational speed of your drive gear. In most gear calculations this is given in rotations per minute (RPM) though other units of 2.We can now easily sort out some simple maths to make our gear. a. How big/small do we need the gear teeth to be (diameter)The smaller the gear the smaller the teeth need to be. b. All the teeth that are going to mesh (connect) together must be the same size so calculate your smallest gear first. 3.
