Abstract
The invention concerns an instrumented antifriction bearing device provided with a non-rotating part comprising a non-rotating ring (2) and sensing means (11), a rotating part comprising a rotating ring (4) and coding means (16), and at least a row of rolling elements (6) arranged between the two raceways (3, 5) of the non-rotating (2) and the rotating (4) rings, the sensing means (11) being fixed in a groove (10) of said non-rotating ring (2) arranged proximate to a radial lateral surface (2a) of the non-rotating ring (2). The non-rotating part further comprises sealing means (21) arranged axially between the sensing means (11) and the rolling elements (6) substantially at the groove (10), the sealing means (21) being separate from the sensing means (11).
Claims10
An instrumented antifriction bearing device of the type provided with a non-rotating part comprising a non-rotating ring and a sensor means, with a rotating part comprising a rotating ring and an encoder means, and with at least one row of rolling elements arranged between two raceways of the non-rotating and rotating rings, the sensor means being fixed in a groove of the non-rotating ring arranged near a radial lateral face of said non-rotating ring, the non-rotating part further comprising a sealing means arranged axially between the sensor means and the rolling elements substantially at the groove, the sealing means being distinct from the sensor means, wherein the sealing means is arranged radially between a support of the sensor means and the rotating ring.
A method of assembling an instrumented antifriction bearing device of the type provided with a non-rotating part comprising a non-rotating ring and a sensor means, with a rotating part comprising a rotating ring and an encoder means, and with at least one row of rolling elements arranged between two raceways of the non-rotating and rotating rings, in which a sealing means is placed axially between the sensor means and the rolling elements, the sealing means being distinct from the sensor means, the sensor means being fixed in a groove of the non-rotating ring arranged near a radial lateral face of said non-rotating ring, the sealing means being arranged substantially at the groove, the sealing means being arranged radially between a support of the sensor means and the rotating ring.
