Power-Core gear segment and pinion in high-speed card feeder

A high frequency reciprocating gear and pinion being used in a feeder to insert postcards into magazines was suffering frequent breakdowns. Sealing the gearbox to permit lubrication that would prevent wear was not an option, and so Intech was approached to design a non-lubricated solution that could accommodate shock loads 5 to 10 times higher than the running torque of the application.

Intech Power-Core™ gears exhibit a high load sharing factor, an important quality when handling e-stops or shock loads. The load sharing factor, a measure of multiplying the load-bearing capacity of an individual tooth, is optimized for each application. Because the key way is cut into the metal hub and not the plastic, Power-Core eliminates the weak spot inherent in conventional plastic gears.

The metal hub absorbs all key way stresses, transferring maximum torque to the composite gear teeth. The teeth are made of a lightweight plastic composite, weighing just 0.037 pounds per cubic inch.

Torque of Power-Core gear approximates that of cast iron, but without the brittleness, weight, lubrication, and teeth breakage. As a result, Power-Core gears can reach higher speeds, increasing the throughput of your equipment. We can precisely calculate torque capacity, allowing Power-Core gears to replace metal gears in many applications.

Power-Core gears can operate without lubrication at pitch line speeds up to 15 feet per second. When a special friction-reducing coating is added, you can double gear speed to 30 feet per second.
