Title:
BEARING WITH ROTARY SENSOR
Document Type and Number:
Japanese Patent JP2007024778
Kind Code:
A
Abstract:
To provide a bearing with a rotary sensor that can effectively discharge electromagnetic wave noise to the outside by a simple structure.
The bearing with a rotary sensor includes a magnetic sensor 25 for measuring a rotation number, a rotation direction, or a rotation speed of a rotary shaft having a bearing inner ring 11 and a bearing outer ring 12. In the bearing, a noise filter for eliminating the electromagnetic wave noise that is mixed into the output of the magnetic sensor 25 is provided, and a frame grounding wire 33 connected to the frame grounding line of the noise filter is connected to the bearing outer ring 12 by contacting a plate spring 31 to a side plate 34 in a groove 29.
