Project Background

  • There are 2 Bearings in the iGen Printer System supporting

the fuser roller

  • Every 200,000 prints the fuser roller assembly comes in for

remanufacturing

  • Bearing is reused a maximum of 4 times
  • Currently, there is no quantitative test to qualify bearings

– Potentially leads to many good bearings being scrapped

  • Customer wishes to use the machine as a design tool

Machining

  • Manual Machining

– Motor Block – Mandrels (press and slip fit) – Arbor press fixtures – Clamp attachment – Clamp frame

  • CNC Machining

– Clamp bore

Data Acquisition

  • Designed a signal conditioner to power

accelerometers

  • Pairs with NI 6210 DAQ
  • DAQ outputs accelerometer readings and motor

speed

Testing

  • Performed 10+ MSAs
  • Refined SOP
  • Passed MSA using 3

bearings and 7

  • perators

Data

  • RMS between 0.1 and 0.7 g’s
  • 13 ranges of resolution

– Differentiate ±0.025 g

  • Acoustic machine passed all “good” and “bad” bearings

Recommendations-Operations

  • Establish pass/fail threshold for bearings

– Send a range of bearing to Arnprior

  • Further automate process

– Use motor controller with computer input

  • Purchase new signal conditioner
  • Remove second accelerometer and drop down rails

Recommendations - Hardware

  • Make bearing clamp out of steel
  • Enlarge dowel pins
  • Hardened shaft
  • Second press-fit mandrel
  • Larger arbor press
