Belzona® Offers The Keyway To Success

 
 

Industry:

General Industry (GIND)

 
 

Application:

Mechanical Power Transmission (MPT)

 
 

Customer Location:

Washington, USA

 
 

Application Date:

1992

 
 

Application Situation:

Large punch press keyway.

 
 

Problem:

The keyway on this large punch press had been pounded oversize front, with a back and forth action ending in a hard stop each way.

 
 

Products:

Belzona 1111 (Super Metal)

 

Substrate:

Steel

 
 

Application Method:

Both halves of the keyway were worn, but the shaft was worn more than the sheave. The keyway was grit blasted for maximum bonding. The sheave side was formed first then the shaft was formed, using the sheave to center the new keyway. The application was carried out in accordance with Belzona Know-How System Leaflet MPT-4.

 
 

Belzona Facts:

Removal of the shaft for machining would take much too long. The keyway was reformed in-place and the punch press is still operating 22 years later. This keyway takes a beating daily and nothing works as well as Belzona.
