$WPNV -- WPS, INC.

The mission of WPS, Inc. is to provide cost-effective preventative maintenance and quality solutions for custom wind turbine and gearbox rebuilds. We rebuild all our gearboxes to standards that exceed the original engineering specifications.

WPS, Inc., currently operates two facilities that are equipped to maintain, repair and refurbish turbines, blades and towers along with a state-certified welding facility. WPS has a unique focus and expertise in custom rebuilding of wind turbine gearboxes. No other company that we are aware of is dedicated exclusively to this work or does custom rebuilding. Too often “standard practice” is to merely replace worn parts with standard replacements and return the gearbox to the manufacturer’s original specifications with no improvements made to the original design. There is little to be gained by simply replacing a part with another exact duplicate part. We prefer to offer our customer the option of a premium upgrade.

At WPS, we custom engineer and retrofit all parts that need replacement. We rebuild all our gearboxes to standards that exceed the original engineering specifications. The ability to offer our customers significant upgrades and retrofits, and our custom-engineered equipment and quality testing procedures put us ahead of our competition.

Gearboxes –
We do more than just replace parts. WPS is a company that takes great pride in finding and analyzing problem areas in a gearbox and then providing superior engineering solutions.

Rebuilds -
Rebuilds include many or all of the following:

• Crack detection


• Rockwell hardness testing


• Upgrade bearing brand, size, and type


• Refurbish worn shafts


• Bore and sleeve cases


• Adjust interference fits


• Relocate case bearing journals


• Adjust shimming specifications


• Repair gear case


• Upgrade to synthetic oil

Whenever possible, worn gears and pinions are turned so they run on the reverse, unworn side, and broken teeth are repaired, significantly increasing the life of an expensive part and saving our customers money. We do not sell our customers parts they do not need. All rebuilds are thoroughly tested for quality assurance before being shipped to the customer.

In-house capabilities include:

• Modifying gear set ratio


• Modifying gear geometry


• Exchanging OEM gear sets


• Applying keyless gear-to-shaft applications


• Upgrading gearbox lubrication systems


• Installing full-flow gear oil filters


• Enhancing case strength


• Sourcing or custom manufacturing obsolete parts
