Abstract
There is provided a condition detection apparatus for detecting a present operating condition of a linear rolling motion guide apparatus, and the condition detection apparatus includes an AE sensor 1 for detecting a waveform elastically generated at least due to rolling of balls included in the linear rolling motion guide apparatus and mutual collision of the balls and generating an electric detection signal corresponding the detected waveform, a waveform shaping unit 2, an A/D converter 3, and a signal processing unit 4 judging a content of the operation condition in response to the generated detected signal Sae.
Claims14
A condition detection apparatus for detecting a present operation condition in a linear rolling motion guide apparatus comprising:
- detection means for detecting a wave motion elastically generated on the basis of at least either one of contact or collision of a movable member or a track member to a rolling member contained in the linear rolling motion guide apparatus, contact or collision of a rolling surface to the rolling member contained in the linear rolling motion guide apparatus, or mutual contact or collision of the rolling members themselves, at a time when a plurality of rolling members contained in the linear rolling motion guide apparatus revolve in a circulation section therein, and generating an electric detection signal in accordance with the detected wave motion;
- and
- judgment means for judging a content of the present operation condition in response to the generated detection signal.
A condition detection method for detecting a present operation condition in a linear rolling motion guide apparatus comprising:
- a detection step for detecting a wave motion elastically generated on the basis of at least either one of contact or collision of a movable member or a track member to a rolling member contained in the linear rolling motion guide apparatus, contact or collision of a rolling surface to the rolling member contained in the linear rolling motion guide apparatus, or mutual contact or collision of the rolling members themselves, at a time when a plurality of rolling members contained in the linear rolling motion guide apparatus revolve in a circulation section therein, and generating an electric detection signal in accordance with the detected wave motion;
- and
- a judgment step for judging a content of the present operation condition in response to the generated detection signal.
A condition detection program, wherein a condition detection apparatus for detecting a present operation condition in a linear rolling motion guide apparatus, which includes detection means for detecting a wave motion elastically generated on the basis of at least either one of contact or collision of a movable member or a track member to a rolling member contained in the linear rolling motion guide apparatus, contact or collision of a rolling surface to the rolling member contained in the linear rolling motion guide apparatus, or mutual contact or collision of the rolling members themselves, at a time when a plurality of rolling members contained in the linear rolling motion guide apparatus revolve in a circulation section therein, and generating an electric detection signal in accordance with the detected wave motion, includes a computer which is operated as judgment means for judging a content of the operation condition in response to the generated detected signal.
