Curvilinear Motion Systems LinearRotaryCurvedLinear + Curved = Curvilinear
![Page 12: Curved Motion System Design for Machinery and Automation](https://reader034.vdocuments.net/reader034/viewer/2022042619/58890feb1a28ab4a5c8b57c9/html5/thumbnails/12.jpg)
Guide Wheel Based Motion Basic principle
Guide wheel rolls on matching track surface
• Wheels are ball bearings with external running surfaces
• Rails are linear profiles with running surfaces
• Rings are curved rotary profiles with running surfaces
![Page 13: Curved Motion System Design for Machinery and Automation](https://reader034.vdocuments.net/reader034/viewer/2022042619/58890feb1a28ab4a5c8b57c9/html5/thumbnails/13.jpg)
Guide Wheel Based Motion Key Advantages
Vee surfaces generate a “wiping” action when used on matching linear vee rails
• Difference in peripheral speed = velocity gradient
Works in harsh environments exposed to dust, dirt or debris
• Wiping action pushes debris out of the way• Often the best solution for dirty applications
![Page 14: Curved Motion System Design for Machinery and Automation](https://reader034.vdocuments.net/reader034/viewer/2022042619/58890feb1a28ab4a5c8b57c9/html5/thumbnails/14.jpg)
Guide Wheel Based Motion Key Advantages
Bearing balls are internal, protected and lubricated for life
• Seals or Shield options
Big advantage over recirculating ball linear guide technology
• Balls run on exposed rails directly• Limited seal protection• Debris ingress leads to rapid failure
![Page 15: Curved Motion System Design for Machinery and Automation](https://reader034.vdocuments.net/reader034/viewer/2022042619/58890feb1a28ab4a5c8b57c9/html5/thumbnails/15.jpg)
Guide Wheel Based Motion Key Advantages
Provides smooth & quiet operation with high load carrying capacity
• High quality bearing grade steel Carbon and stainless steel
• Hardened for durability• Precision ground surfaces
Very low stiction and coefficient of friction Industrial grade and performance
• Suitable for continuous use
![Page 16: Curved Motion System Design for Machinery and Automation](https://reader034.vdocuments.net/reader034/viewer/2022042619/58890feb1a28ab4a5c8b57c9/html5/thumbnails/16.jpg)
Guide Wheel Based Motion Key Advantages
Adjustable eccentric bearing mount• Set preload between wheel and rail/ring• Adjust play due to wear• Longer usable life• Replace rail/ring, or wheel
Profile rail must replace both
![Page 17: Curved Motion System Design for Machinery and Automation](https://reader034.vdocuments.net/reader034/viewer/2022042619/58890feb1a28ab4a5c8b57c9/html5/thumbnails/17.jpg)
Motion Components Guide Wheel Designs
Slimline bearing type• Single row ball bearing• Low profile, lower capacity• Lowest cost
Twin bearing type• 2 individual ball bearings• Compliance, smoother running• Tolerates misalignment
Slimline
Twin
Double
Double row bearing type• Single piece double row ball• Higher load capacity• Slightly more debris tolerance
Floating bearing type• Needle rollers• Axial movement• Prevents binding on parallel rails
