Abstract
The utility model relates to a magnetic induction coil which mainly comprises an inner coil and an outer coil, wherein the inner coil and the outer coil are interconnected to form an integral coil by a bottom edge, and an annular groove is formed between the inner ring and the outer ring. The edge of the outer coil is outward folded to form an L shape, and magnetic layers are attached to the inner wall and the side edge of the outer coil. The utility model has the advantages of compact structure, light weight and high sealing performance, makes the primary blurring signals of the inductor signals change into digital signals, and is an important part of an inductor. The structure is applied, the traditional sealing coil only can have single sealing function, which is changed, and the magnetic induction coil becomes one part of the inductor. The function of the sealing coil is improved; since the density of magnetic materials is small, the weight of the parts of cars is reduced, and the utility model adapts to the trend that the cars are developed toward miniaturization.
Description
Technical field
The utility model relates to the seal ring field, mainly is a kind of Magnetic induction coil that is used on the automobile bearing.
Background technique
Traditional seal ring only has the effect of single sealing.According to the compactedness requirement of automobile to component, reduce the weight of auto parts and components, adapt to the trend of automobile to the miniaturization development.Seal ring will be from single sealing function to multi-functional transformation.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure, changed the effect that traditional seal ring can only single sealing, makes it to become the Magnetic induction coil of the part of sensor.
The technological scheme that its technical problem that solves the utility model adopts.This Magnetic induction coil mainly comprises inner ring and outer ring, and inner ring and outer ring be by the base circle in aggregates that interconnects, and forms circular groove between inner ring and outer ring; The outside flanging in outer ring constitutes shape, on the inwall and side of magnetic layer attached to the outer ring.
The effect that the utility model is useful is: the utility model compact structure, in light weight, improved sealability, and make sensor signal change digital signal into by original blurred signal, be the important component part of sensor.The application of this kind structure has changed the effect that traditional seal ring can only single sealing, makes it to become the part of sensor, has improved the seal ring effect.Because the density of magnetic material is very little, thereby reduced the weight of auto parts and components, adapted to the trend of automobile to the miniaturization development.

Description of reference numerals: whole circle 1, inner ring 1-1, outer ring 1-2, base 1-3, circular groove 1-4, magnetic layer 2, bearing inner race 3, bearing outer ring 4, flange plate 5, interior black box 6, steel ball 7, retainer 8, exterior seal ring 9, outer seal ring 10;
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.The Magnetic induction coil structure is to design according to the blocking of bearing component structural, integrated requirement, mainly meets the tendency in the hub-bearing unit seal ring outside.This Magnetic induction coil mainly comprises inner ring 1-1 and outer ring 1-2, and the internal diameter size of inner ring 1-1 is corresponding with the external diameter size of bearing inner race.Inner ring 1-1 and outer ring 1-2 be by the base 1-3 circle 1 in aggregates that interconnects, and form circular groove 1-4 between inner ring 1-1 and outer ring 1-2; 1-2 outside flanging in outer ring constitutes shape, on the inwall and side of magnetic layer 2 attached to outer ring 1-2.Magnetic layer 2 is selected the magnetic rubber material for use, and inside forms several equally distributed magnetic fields, thereby forms the Surface field of certain intensity.
The utility model is used on bearing and is seen shown in Figure 4ly, and this bearing mainly comprises bearing inner race 3, bearing outer ring 4, flange plate 5, interior black box 6, steel ball 7, retainer 8, exterior seal ring 9 and outer seal ring 10; Magnetic induction coil is attached to the outside of black box 6 in the bearing, has played certain seal action, has improved the product hermeticity energy.Because little, the compact structure of density of magnetic material, thereby reduced the weight of bearing component, adapted to the trend of bearing to miniaturization, lightweight development.The application of this kind Magnetic induction coil structure is to form signal by the probe cutting magnetic line, makes sensor signal change digital signal into by original blurred signal, and its structure is the important component part of sensor.This kind Magnetic induction coil structure has all proposed strict requirement to technical specifications such as surface sense field strength, magnetic pole deviation, induction coercive forces, therefore also requires quite strict on manufacturing technology.
