Blue Diamond Machinery Redesign of Driving Teeth to Improve Performance by Team Members: Kelly Hogue Kristen Tucker Matthew Gassen Buck Melton Prepared for CONEQTEC Universal and BAE 4012
Mission statement • Blue Diamond Machinery strives to improve products by implementing high quality designs, increasing efficiency, and surpassing the demands of our clients.
Project sponsor • CONEQTEC Universal • Manufacturer of skid steer attachments • President Gary Cochran
Minimal cutting depth To increase depth of cut, the diameter of the blade must increase, therefore, increasing the weight of the attachment. Production Model Provided by CONEQTEC
Problem Statement • Increase cutting depth to greater than blade radius • Improve prototype to increase useful life • Prohibit hydraulic motor from descending into debris piles
Features of prototype • Depth of cut is close to blade diameter • 18 inches deep. 2.5 inches wide • Powered by hi-flow hydraulic system • 40 hp input to hydraulic motors • Laterally adjustable • CONEQTEC patented design
Rock Saw Prototype Provided by Coneqtec
Statement of Work • Increase useful life of gear teeth from less than 50 hrs to over 100 hrs.
Statement of Work (cont’d) • Prevent hydraulic motors from descending into debris
Statement of Work The longevity problem of the rock saw is due to wear on the gear teeth attached to the saw blade. Options: • Redesign gear mesh • Increase wearability of gear teeth
Statement of Work (cont’d) Test for increase in wearability of gear teeth after instituting • Surface treatments • Surface coatings • Harder material
Statement of work (cont’d) Prevent hydraulic motors from descending into debris • Install a ski guard on motors • Install a stop on depth control
Research • Patents • Rim driven • Cutting (Concrete) • Literature • Track Trenchers • Rock Saws • Surface Treatments • Surface Coatings • Gear configurations
Research (cont’d) • CONEQTEC Patents • Slot cutter depth control • Auxiliary implements attachments
Possible Solutions Increase useful life of gear teeth • Change gear tooth material • Increase tolerance of gear mesh • Surface treatments • Surface coatings
Possible Solutions (cont’d) Institute Alternative Design • New gears mesh into blade eliminating current ring teeth wear
Alternative Design Cont. • Gear guards are installed on blade to protect blade from gear mesh wear
Project Schedule • Fall Semester • Patent Search • Design Concepts • Spring Semester • Fabrication • Testing • Final Design
Thank You • Gary Cochran and CONEQTEC • Dr. Paul Weckler • Jana Moore • BAE Lab
At this time we would like to open the floor to any QUESTIONS?
