As a manufacturer of engineered enclosed drives, Nuttall Gear is accustomed to variances in specification requirements depending on the industry and the function of the gearbox. The duty cycle of these units can vary significantly from heavy shock load on a coal crusher where the service factor can exceed 2.0 to a coiler in a steel mill that can have a service factor of 1.0.
Most gearbox manufacturers are experts in engineering, designing, and building gearboxes. They are not necessarily experts in all of the processes and industries that they support. In many cases, the process is confidential and proprietary, and must not be disclosed to anyone outside the company.
