NTN Corporation (hereafter, NTN) had previously commercialized the “Integrated Rotation Sensor Bearings”*1 and has been selling them around the world, however in an industry first, has developed the “Integrated Rotation Sensor Large Size Bearing” capable of detecting the rotation speed of large bearings (up to 420 mm outer diameter).
Until now, large bearings and rotation sensors had been mounted separately within machinery. The positioning of components required for accurately detecting rotation speed also required delicate adjustment during the equipment assembly stage.
NTN has installed a pulse detection sensor within the still inner ring, and a pulser ring within the rotating outer ring, for applications that use large bearings with a rotating outer ring. Integrating the rotation sensor and bearing eliminates the need for adjustment and positioning during the assembly stage, reduces the number of components required, and results in a more compact bearing size.
The use of a sensor wiring layout mechanism that prevents disconnections allows detection of rotation speed without any damage or errors, even if the shaft and bearing inner ring start to creep (a form of differential rolling). The system can also be used when immersed in oil and under vibrating conditions.
NTN plans to deliver the new bearing to various industrial machinery that requires detection of rotation speed of large bearings, including applications in the construction machinery, iron and steel facilities and wind power generators.
Features:
(1) Integrated rotation sensor and bearing
→ Reduces man-hours required for rotation sensor assembly, reduces the number of components and achieves a more compact housing size.
(2) Use of a sensor wiring layout mechanism that prevents disconnections, even if the shaft and bearing inner ring start to creep (a form of differential rolling)
→ Detection of rotation speed even if the inner ring starts to creep.
(3) Can be used when immersed in oil
→ Capable of accurately detecting rotation speed when mounted within engine oil (oil temperature 120°C × 2000 hours).
(may be affected by the type of oil or additives)
(4) Can be used under vibrating conditions
→ Capable of accurately detecting rotation speed under vibrational acceleration of 10G.
Applicable Bearing Sizes:
Can be used for large bearings up to 420 mm outer diameter.
