Gear ratio of the reducer
Thread Content
Dear sea friends, please provide the method for calculating the gear ratio of reducers. Thank you.
When a mechanical reducer is used, the ratio of the motor’s rated speed nN (r/min) to the speed of the reducer’s output shaft nL is called the speed ratio I (also known as the transmission ratio), where i = nN/nL. The actual calculation is quite simple.
For users, the speed ratio of a reducer is “selected” rather than “calculated”. Calculating the gear ratio of a reducer is the task of reducer designers. In the design manual, different types of reducers come with various gear ratio ranges, allowing one to choose the appropriate reducer based on their own requirements.
For the user, the speed ratio of the reducer is something that is “chosen” rather than “calculated” – what was said above is absolutely correct! Additionally, the power of the motor chosen must not exceed the power allowed by the input shaft of the reducer; the specific values can be found in the manufacturer’s specifications.
