The gear drive simulator (GDS-2000) is specially designed to simulate industrial gearboxes for educational purposes and consists of motors, parallel shaft gearboxes, planetary gears, low speed bearings, high speed bearings and magnetic brakes, so it can be used as a reverse drive unit for wind turbines. GDS can be used to investigate gearbox dynamics and acoustic properties, soundness monitoring, vibration based diagnostic techniques, lubrication status or wear particle analysis, etc.

Detailed Description

With GDS-2000 the effect of gear failure such as surface wear, cracked gears, broken teeth in spur gear or helical gear can be simulated. Rolling element bearing defects such as inner race defect, outer race defect and ball damage may also be regenerated. Clearance adjustment is possible for backlash research. Increasing the amount of backlash does not have other major effects other than noise increase and rotation clearance. However, if backlash is reduced, it may become stuck and result in increased temperature. You can add machine defects one by one, or multiple defects at once so you can study the interaction of various machine defects. Torsional vibrations can be applied by programmable speed control in a variable frequency AC Inverter to study damage symptoms or propagation in the gear.

  • Defective gear can be replaced by simply sliding normal gear, and vise versa
  • Spur or helical gear selectable
  • Intentionally damaged or worn gear can be easily changed to study the effect of  on vibration symptoms
  • Backlash can be changed by moving bearing housing to provide the desired clearance
  • Modular design for easy mounting of faulty bearings or fault gears
  • Standard tabs provided for installing various sensors
  • Development of diagnostic technology and advanced signal processing method
  • Variable speed curve for torsional load
  • Additional equipment can be installed instead of brake
  • Study on low-speed machine fault detection and diagnosys
  • Study on vibration due to gear failure
