Title:
BALL BEARING EQUIPPED WITH ENCODER FOR DETECTING ROTATIONAL SPEED OF WHEEL OF TWO-WHEELED MOTOR VEHICLE, AND DEVICE FOR DETECTING ROTATIONAL SPEED OF WHEEL OF TWO-WHEELED MOTOR VEHICLE, THE DEVICE USING THE BALL BEARING
Document Type and Number:
WIPO Patent Application WO/2011/105366
Kind Code:
A1
Abstract:
A ball bearing equipped with an encoder rotatably supports a wheel of a two-wheeled motor vehicle, can detect the rotational speed of the wheel, and sufficiently prevents foreign matter from entering into the space (19) within the bearing.
The opening of an end of the space (19) within a bearing is closed by a combination seal ring (20) comprising a slinger (21) and a seal ring (22). A circular ring-shaped encoder (9a) is attached and affixed to the outer side surface of an outer circular ring section (24) of the slinger (21). The detection section of a sensor (30) is faced to the outer side surface of the encoder (9a) to enable the detection of the rotational speed of the wheel which rotates together with the outer ring (11a).
