摘要:
The present invention relates to a bearing apparatus with a sensor and a rolling bearing with a sensor used to movers such as automobiles or railway carriers, facility machines of equipment, or machine tools. One of the embodiments comprises a sensor detecting conditions of the rolling bearing, a ring-shaped sensor cover housing the sensor therein and secured to a stationary-side bearing ring, and a ring shaped presser member secured to a bearing housing provided outside in a radius direction of the sensor cover, or secured to a shaft, and an opening portion is provided at a decided portion of the sensor cover, and projections standing toward a side of the presser member are furnished in the circumference of the opening portion, the presser member is defined with cutouts for inserting the projections, and the cutouts are arranged with the projections.

Provided is a magnetic encoder that improves reliability of binding of the annular fixing member and the annular plastic magnet even when the magnetic encoder is to be attached to an outer ring. An axial-type magnetic encoder 1 includes a wrap-around binding part C wrapping around from a sensor-opposed surface A to a back surface B of an inward flange part 2B of an annular fixing member 2. A separated inner peripheral part D separated from a rotating body 10 is formed at an inner diameter-side portion of the inward flange part 2B while an outer diameter-side portion of a back surface of the inward flange part 2B is abutted against the rotating body 10. The inner peripheral part of the annular plastic magnet 3 wraps around to a back surface of the separated inner peripheral part D. The wrap-around binding part C of the annular plastic magnet 3 wrapping around to the back surface of the separated inner peripheral part D does not come closer to the rotating body 10 than the outer diameter-side portion of the back surface B of the inward flange part 2B.

A sensor bearing assembly comprising a rolling element bearing and at least one sensor. The rolling element bearing comprises an inner ring, an outer ring, and rolling elements arranged between the inner ring and the outer ring. The at least one sensor is arranged to convert one or more physical magnitudes to electrical sensor signals. The sensor is attached directly or indirectly to the rolling element bearing. The assembly further comprises a converter unit. The converter unit is arranged to convert the electrical sensor signals to output signals which are different in form, type and/or amplitude in relation to the electrical sensor signals. The converter unit is also enclosed in a separate enclosure, that is the converter unit does not share a housing/enclosure with the sensor. Matching coded detachable connectors are provided between sensor and converter unit, to ensure that they are connected correctly with each other.

The object is to protect the output cables of the magnetic sensor from damages and, at the same time, to make the process of drawing out the output cables easier. A tubular duct 9a for output cables 12 is formed integrally with a sensor housing 9, provided with an opening 14 having a uniform width from the proximal end to the distal end of the duct 9a on the side face thereof. The output cables 12 are put through the duct 9a from this opening 14, and then a slidable lid 15 is mounted to close the opening 14. Thus damage to the output cables 12 connected to a magnetic sensor 7 is prevented and, at the same time, drawing the output cables 12 outside the sensor housing 9 is made easier.

The present invention is intended to provide a manufacturing method of a protective cover having a sensor holder part that has high adhesion strength between a metallic component (1A) and a plastic component and maintains high reliability over a long period of time. The manufacturing method includes: a step of applying a thermoset resin adhesive to a surface of a metallic component (1A) including a joining surface relative to a plastic component; a drying and solidification step of evaporating a solvent contained in the adhesive under a temperature condition at a temperature lower than a temperature at which the adhesive starts a cross-linking reaction; and an injection molding step of placing the metallic component (1A) as an insert between dies (18) and (19) and injecting a molten plastic material from a gate (20) into the cavity.
