This sizing sheet calculates the load tangential load using a general calculation formula. Based on that load tangential load and the specified operating conditions, the sheet shows the results of selection using the selection procedures listed in Pin gear drive unit catalog.
Please consider the characteristics of the equipment you are using and determine for yourself whether the load calculation is appropriate.
