TAPERED ROLLER BEARING INSPECTION SYSTEM
The tapered roller bearing inspection system provides manufacturers with a high
speed solution for inspecting unique quality problems associated with tapered
roller bearings. The system can easily acquire and process an image in well under
one second. The following quality problems are detected:
- Missing Rollers
- Inverted Rollers
- Mixed family rollers
- Bent, scalloped, or cracked cages
- Improper # of characters on cone face
The image processing based system is the result of extensive signal processing
analysis and development. The general capabilities include:
- Detect dimpled and full face rollers
- Operates on metal or plastic cage parts
- Track shift
- Track run
- Track day statistics
The system PC is controlled, using a standard IBM PC compatible processing platform
which has been ruggedized for use in a factory environment. The system components consist a
camera, lens, and lighting unit, which are mounted to an extruded aluminum post. Each
component is independently adjustable along the post. The post to optical axis center is set
at eight inches. The processor and control electronics are supplied in a rugged
chassis equipped with a positive pressure cooling system. Standard OPTO-22
modules will provide an interface to the customers part handling automation PLC.
The signals are:
- “Process image” from PLC
- “Part Accept” to PLC
- “Inspection System Ready” to PLC
The system will easily interface with virtually any in-plant automation PLC. Additional
features include:
