One of our customers, who manufactures packaging machines for the pharmaceutical industry to produce caplets, sought to improve its competitive standing by eliminating the need to lubricate the 16” cast iron main drive gear and replacing it with a lubrication free Intech Power-Core™ gear.
Upon installation of the lubrication free Intech gear, the engineers ramped up the output to 600 caplets per minute (cpm), the industry standard, and discovered that there was no vibration previously experienced with the heavy cast iron gear. Encouraged by the performance of the low inertia Intech Power-Core™ gear, they increased the output to 700…800…, all the way to 1200 cpm. Even at this speed the machine was running smoothly and without vibration.
This was in contrast with all the previous experience using the cast iron gear which reached its critical RPM around 700 RPM, at which point the machine shook violently, and the reason why the output had been established at 600 cpm.
The customer settled on an output of 800 caplets/min as a standard for the company’s brand, a 25% increase over competitive machines. The first reward came shortly after introduction of the new machine. A company producing caplets used in automotive air bags sought to increase its capacity by 2400 caplets/min. Our customer was able to satisfy that demand with three machines that don’t require lubrication, where all its competitors quoted four machines that required constant lubrication and frequent shut down for maintenance.
Low inertia often becomes the dominant, albeit unexpected benefit of changing to self-lubricating Power-Core™ gears. The main drive in the DaVinci surgical robot is another good example.
