Encoder device for speed sensor and roll bearing equipped with such a device |
摘要 |
<p>The coder for a rotational speed sensor is mounted adjacent to the bearing (1) on which the element turns. It comprises a sensor (7) solidly attached to the fixed element, with the rotating coder element (12) passing in front of the sensor with a small air gap. The coder element comprises a multi-polar magnetised ring, capable of producing within the sensor a periodic signal of frequency proportional to the speed of rotation of the rotor element. The coder is fixed on to an internal surface of a rigid protection and support element (13) made of non-magnetic metal. The external face of the protection element (13) moves in front of the sensor (7).</p> |
