A sensor bearing unit comprising: Besides, at least one of the lateral and cylindrical surfaces is provided with a textured area comprising a plurality of ribs, and the abutment portion and/or the fixing portion of the target holder is made of a hard material and comprise a soft coating covering the hard material and inside which the ribs are engaged.

Sensor bearing unit and method of manufacturing such a sensor bearing unit

A method for mounting a sensor bearing unit providing a bearing and an impulse ring provided with a target holder and with a target mounted on an axial portion of the target holder. The method including measuring an eccentricity Ebetween the target and the axial portion of the target holder, measuring an eccentricity Ebetween a groove made in the bore of an inner ring of the bearing and the bore, introducing the target holder inside the groove, turning the target holder inside the groove to an angular position in which the eccentricity Ebetween the target and the bore of the inner ring is less than or equal to a predetermined value which is lower than the sum of the eccentricities Eand E, and securing the target holder inside the groove of the inner ring at the angular position.

Method for mounting a sensor bearing unit, and sensor bearing unit adapted to such a method

A method for coating a sensor unit providing at least one sensor element and a sensor body supporting the sensor element. The method includes applying, in the assembled state of the sensor unit, a coating on the exterior surface of the sensor unit such as to coat the sensor element and the sensor body.

Method for coating a sensor unit, and associated sensor unit

The method provides for the manufacturing a sensor bearing unit including a bearing having a first ring and a second ring capable of rotating concentrically relative to one another, and an impulse ring provided with a target holder secured to the first ring and with a magnetic target mounted on the target holder. The method further includes securing the target holder to the first ring and magnetizing the magnetic material of the magnetic target after the step of securing the target holder to the first ring.

Method for manufacturing a sensor bearing unit

A method for manufacturing of a target holderfor a sensor bearing unit. The target holder providing at least an axial fixing portion secured to a ring of the sensor bearing unit, and a radial portion extending at least radially with respect to the axial fixing portion, a curved linking portion being formed between the axial fixing portion and the radial portion. The method further providing a step of shot peening at least on the internal surface of the curved linking portion of the target holder.

Method for manufacturing a target holder for a sensor bearing unit, and associated sensor bearing unit

A sensor bearing unit includes a bearing having a first ring and a second ring, and an impulse ring provided with a target holder, with a target mounted on the target holder, and with a sleeve secured to the first ring. The target holder having a mounting portion secured to the first ring of the bearing. The target holder has at least anti-rotation feature axially spaced apart from a free end of the mounting portion and cooperating with a complementary anti-rotation feature of the first ring so as to prevent angular movement of the impulse ring relative to the first ring. The anti-rotation feature of the target holder extends into the complementary anti-rotation feature of the first ring.

Sensor bearing unit

The sensor bearing unit provides a bearing having an inner ring and an outer ring centered on an axis, the inner ring mounted on a shaft, and an impulse ring provided with a target holder and with a target mounted on the target holder, the target holder being secured to the inner ring. The target holder includes anti-rotation features adapted to cooperate with complementary anti-rotation features of the shaft so as to prevent angular movement of the impulse ring relative to the shaft by abutment in circumferential direction.

Sensor bearing unit and associated apparatus and manufacturing method

A sensor bearing unit includes a bearing having a first ring and a second ring, and an impulse ring provided with a target holder, with a target mounted on the target holder, and with a sleeve secured to the first ring, the target holder being axially mounted between a lateral face of the first ring and the sleeve. The first ring having at least one anti-rotation feature cooperating with at least one complementary anti-rotation feature formed on the impulse ring so as to prevent angular movement of the impulse ring relative to the first ring.

A method for manufacturing a sensor bearing unit includes providing a bearing having a first ring and a second ring capable of rotating concentrically relative to one another, and an impulse ring provided with a target holder secured into a groove made in a cylindrical surface of the first ring, and with a magnetic target mounted on the target holder. The method including applying on a first ring blank a heat-treatment in which the metal is hardened, hard machining the groove in the cylindrical surface of the first ring blank after the step of heat treating, and introducing and securing the target holder of the impulse ring inside the groove of the machined first ring. Also a sensor bearing unit.

Method for manufacturing a sensor bearing unit, and associated sensor bearing unit

The present invention relates to a mechanical system with a one-way clutch, for example a pulley for a motor vehicle alternator, comprising a first element and a second element which are able to move one with respect to the other in rotation about a central axis and delimit an annular housing radially to the central axis, a one-way clutch device arranged in the annular housing, and at least one rolling bearing arranged in the annular housing. The mechanical system is characterized in that the rolling bearing comprises at least one pressed ring distinct from the constituent elements of the one-way clutch device. The invention also relates to an alternator comprising such a mechanical system configured as a pulley with a one-way clutch.
