Cogmatic Helps Customer Replace Worn-Out Gear Versus Entire Equipment
CASE STUDY #6 – Make a Gear… when all you have is a Pinion
A U.S. manufacturer that specializes in rebuilding older drum systems.
Their customer had a very large drum with a ring gear that needed to be replaced. The problem was that the gear part was very old and no longer being manufactured. They had no drawings, specs or catalog information about the gear – except the name of the original manufacturer of the equipment.
Although the rest of the system was functional, if they couldn’t replace the worn-out part, their customer was faced with purchasing a brand new assembly. At the time, the end-user felt they could not make the economic justification for purchasing new equipment.
When our customer approached us for assistance, they provided our team with the Outside Diameter of the drum and a count of the remnants of the worn-out teeth. Along with some field measurements taken by their customer, Cogmatic was able to determine what the Ring Gear specification would have to be. Cogmatic’s engineers still required an unknown factor: What was the pressure angle for the gear?
To solve this part of the puzzle, the customer purchased a replacement pinion from a company that specializes in maintaining stocks of old obsolete parts. Working with one of our vendors, Cogmatic was able to take appropriate measurements of the tooth form and verify the pressure angle. With that specification confirmed, we were able to make the ring gear. Our customer replaced the gear and pinion and their customer enjoyed the renewed functionality of their equipment without investing in a new system.
