Stainless steel chain plating drum drive replaced by lube free gears

Posted by Simon Barrell on Jan 31, 2011 2:22:00 PM

One of our customers, who use an aggressive liquid bath in a plating process for coating metal parts, was experiencing a frequent breaking of the stainless steel chain drive which was corroding in the highly aggressive environment.

The parts are loaded into a large plating drum with a mesh exterior, which is then lowered into a tank containing a highly corrosive solution and heated to high temperatures between 120°F – 150°F. After coating, a series of cleaning and coating cycles are repeated across a battery of baths. A motor engages the drum drive, which needs to rotate slowly and steadily while carrying a high load into each step of the cleaning and coating process. The heavy metal parts in the drum can shift suddenly as the drum rotates, causing heavy shock load to be absorbed on the drive. The stainless steel chain, weakened by corrosion would give up under the shock load.

Intech engineers designed a large lubrication free Intech Power-Core™ gear and included a circular series of 2” diameter cast in ports made of Inconel™ in order to securely attach the gear to the drum. They also integrated a Power-Core bearing block in the shaft.

The Intech gear is resistant to the corrosive environment and was designed to absorb the sudden shock load, and proved to offer substantial savings to the customer.

Double-rowed Power-Core drive sprocket in packaging machine

Posted by Simon Barrell on Apr 19, 2010 5:20:00 PM

In food industry applications lubrication is always an issue, so for a packaging machine we designed a composite double-rowed drive sprocket machined from Intech Power-Core™ material with a SS core that prevents abrasion on the steel chain, even at high operating speeds.

This chemical resistant sprocket is corrosion proof and ensures that no lubricant is required which could contaminate the food.

One drive sprocket is used for two different chain circuits, and this component provides an integrated solution with a cast-in stainless steel hub to securely attach both sprockets to the shaft.

Intech Power-Core™ sprockets are available with or without metal core. The material’s properties lend themselves to superior wear characteristics of the sprocket teeth. Intech Power-Core™ sprockets do not wear out the chain, reduce noise and absorb shock and vibration.

High speed rotating face cams machined from Power-Core™ outlast steel

Exact steerage requires dimensionally stable cam tracks with narrow tolerances. Our cams are precision machined from solid blocks of cast Intech Power-Core™ material, offering a longer lasting solution than stainless steel.

In high speed machines Intech Power-Core™ cams exhibit damping behavior which leads to reduced stress peaks. Additionally the high performance plastic cam offers exceptional resistance to wear with limited or no lubrication, which is critical to avoid contamination.

The face cam converts circular motion to linear motion or vice versa, typically it is a disc with a groove cut in its face, in which a cam follower travels. The attached image shows such a cam used in a tableting machine.

In this case the customer required self-lubricating material performance and had experienced constant stress problems using cams machined from plastic materials with low levels of crystallinity, such as Delrin®. However they found that Power-Core™ material, with higher crystallinity levels, can be used to produce a more stable cam that does not suffer stress peaks.

Industries in which our cams have been used include packaging, food processing, printing, as well as stitching machines and other general engineering applications.
