Each application has its own conditions and operating requirements. Peavey received the speed reducer with modified shaft end, cooling fans, Falk NRT low-speed backstop, and Falk SteelflexR coupling on the output shaft extension. The existing fluid coupling, salvaged from the old system, was re-installed on the high speed shaft. Installation time easily bested the one or two days typically needed to complete such a job. Life of the new unit will be prolonged due to the higher service factor and cooling fans, which will keep the gearbox cooler than its neighbor.
Heat can destroy lubricants and oil seals, which ultimately leads to gear failure.
A lot of the companies that I contacted for a replacement gearbox didn't have stock on hand. I didn't want to wait three or four months for spare parts. Maintaining the Unit To keep the speed reducer operating at maximum efficiency, a rigorous continuous maintenance program will be followed including periodic tests of temperature, oil, and noise levels. An oil sample costs a fraction of the cost of a new gearbox. Ongoing service is also expected to be simplified with the addition of a tapered-grid coupling on the low speed shaft of the gearbox.
