Recommended Method of Selecting
the Proper Size Gear Drive

Years of experience have taught us that quick and easy methods of selecting gearboxes don’t always provide the desired result. As an example, the same size gearbox with two different ratios will have different life expectancies. The reason is simple, the more teeth a gear has, the more area available to sustain loads, which generally will increase life. Other factors to consider are: the output shaft “drop” or distance the center of the load on the shaft extends from the gearbox. Longer “drops” will place more load on the output shaft bearings and shorten the gearbox life, if output shaft bearing life is a limiting factor.

To aid in the selection of the proper gearbox, Eskridge has developed a proprietary computer model. The data that you provide as representative of your conditions is input including multiple duty cycle conditions. The output from this model will include the recommended gearbox and expected composite life in hours, based on input conditions.

You can find the application review forms in the Gear Drives Technical Bulletins section of this website. Simply complete this form, with a profile of your operating conditions, and forward it to your Eskridge representative for assistance and we will respond with recommendations and calculated gearbox life, based on your conditions.
