Transmission ratios

Reduction ratios can be obtained using the tables shown on following pages. Please take care when obtaining gear ratios we would not recommend using a ratio of more than 8 if a higher ratio is required then two drives should be used in tandum, gearing down the secondary drive to maintain a high speed of rotation on the intermediate drive shaft. If a even drive ratio is required we recommend using the largest number of teeth possible within the available paramiters.
