えて回転速度を検出するようにした装置等がある。The rotational speed of the axle is measured in order to operate the speedometer, tachometer, brake anti-lock device, etc., but as a conventionally known device for detecting the rotational speed of wheels or axles of automobiles, etc. As disclosed in No. 46331, a bearing is sealed with a sealing body and a device for generating a magnetic field is attached to the sealing body to rotate the rolling elements of the bearing or the impulse ring fitted to the inner ring of the bearing. A device that detects the rotational speed by capturing changes in the magnetic field generated by the device, or as disclosed in Jitsuma No. 152971 (1988), an axle that rotates with the wheel relative to the axle housing of the vehicle can be freely rotated. A sensor rotor is a nut that is fixed and rotates together with the axle, and a large number of uneven teeth are formed on the outer periphery of the nut, and a pick-up sensor detects changes in the magnetic field caused by the rotation of the sensor rotor to determine the rotation speed. There are devices designed to detect this.

センサ２０を対向配置するようにしたもの等がある。As shown in FIG. 6, as another axle rotation speed detection device, an impulse ring 22 having a large number of concave and convex teeth is press-fitted into an axle bearing inner ring 21, and rotation speed detection sensors 20 are arranged facing each other at predetermined intervals. Alternatively, as shown in FIG. 7, a nut 23 and an impulse ring 24 having a large number of uneven teeth are integrally formed as a sensor rotor for changing the magnetic field, and a rotation speed detection sensor 20 is opposed to the impulse ring 24. There are some that are arranged in such a way.

になっているものでは、スパナを差し入れるための余分
なスペースを軸方向に設けなければならずナツトの形状
も複雑になり過ぎる。In the type of axle rotation speed detection device mentioned above, in which an impulse ring is press-fitted into the inner ring of the bearing, the nut seating surface is generally larger than the inner ring end surface. tends to fluctuate. Further, in the case where the impulse ring and the nut are integrally formed, an extra space must be provided in the axial direction for inserting the spanner, and the shape of the nut becomes too complicated.
通常インパルスリングは歯数が多いほど、インパルスリ
ングとセンサとの距離が小さいほど検出精度が良くなる
が、小さすぎるとインパルスリングとセンサとの接触が
生じる恐れがあり、位置決め精度が悪いと必然的に検出
精度も悪くなる。Normally, the more teeth an impulse ring has, the smaller the distance between the impulse ring and the sensor, the better the detection accuracy, but if it is too small, there is a risk of contact between the impulse ring and the sensor, which will inevitably occur if the positioning accuracy is poor. Detection accuracy also deteriorates.
この発明はかかる問題点に鑑みてなされたものであり、

The purpose is to provide an axle bearing rotation speed detection device that does not require extra axial space, has a small distance between the impulse ring and the sensor, and has good positioning accuracy and detection accuracy when installed.

めたことを特徴とする。That is, in order to solve the above-mentioned problems, the present invention provides an axle bearing rotation speed detection device that includes a washer part integrally provided with a NAND fixed to the axle or the bearing inner ring, and the washer part has uneven teeth on the axial side surface. It is characterized by being formed by press-fitting an impulse ring having Further, an impulse ring having concave and convex teeth on the axial side surface is press-fitted into the washer portion of the NAND, and a cover with a rotation speed detection sensor fixed to the axle housing or the outer ring of the bearing is fitted, and the concave and convex teeth of the sensor and the impulse ring are fitted. and are arranged facing each other at a predetermined interval.
ナツトに圧入するインパルスリングは径を大きくとるこ
とが出来るので凹凸歯の数も多くすることが可能である
。また、ナツトに圧入したインパルスリングは軸受をシ
ールする役割を果たす。Since the impulse ring that is press-fitted into the nut can have a large diameter, it is also possible to increase the number of concavo-convex teeth. The impulse ring press-fitted into the nut also serves to seal the bearing.

リングとは別体であるからナツト締め付は時のナンドの
軸方向移動によってインパルスリングとセンサ間のギャ
ップが狂うことはない。Even when the nut is screwed onto the axle and tightened, the NAND and the impulse ring are separate bodies, so the gap between the impulse ring and the sensor will not be disturbed by the axial movement of the NAND when tightening the nut.
また、センサを固定したカバーは軸受外輪側に嵌着され

なる。Further, since the cover that fixes the sensor is fitted onto the outer ring side of the bearing, the gap between the end face of the sensor and the uneven teeth of the impulse ring is small (and positioning can be performed with high precision).

A sensor 9 for detecting the number of rotations is screwed and positioned. This sensor 9 is designed to generate a magnetic field and sense changes in the magnetic field, and detects changes in the surrounding magnetic field (that is, changes in magnetic permeability) caused by the rotation of the concave and convex teeth 7a of the impulse ring 7, and determines the rotational speed of the axle. It is designed to detect.

決めを正確にしなければならない。As described above, in this rotation speed detection device, the impulse ring 7 is press-fitted into the washer part 6a of the nut 6, and the cover 8 with the sensor 9 screwed is fitted to the axle housing 3, and the end face of the sensor 9 and the impulse ring are fitted. A small gap is formed between the impulse ring 7 and the concave and convex teeth 7a of the impulse ring 7, but in order to improve the detection accuracy of the rotation speed, the concave and convex teeth 7a of the impulse ring 7 should be increased. It is necessary to position the gap between the end face of the sensor 9 and the end face of the sensor 9 small and with high precision. Therefore, the nut 6 screwed onto the axle 1 must be prevented from turning, and the positioning must be accurate when press-fitting the impulse ring 7 and when fitting the cover 8 with the sensor 9 screwed onto the axle housing 3. Must be.

After screwing the nut 6 onto the axle l and adjusting the bearing preload, the protrusion 6b of the nut 6 is caulked and fixed in the recess 1b of the axle 1. In this case, since the nut 6 and the impulse ring 7 are separate bodies, deformation when the nut 6 is crimped does not affect the position of the impulse ring 7.

となる。Also, attach the impulse ring 7 to the washer portion 6a of the nut 6.
When press-fitting into the axle housing 3, a jig 10 is used as shown in FIG. The distance between the end surface 10a of the jig 10 and the end surface 10a of the jig 1O is made constant. As shown in FIG. 5, the cover 8 has two steps of outer diameter 8a and 8b, the outer diameter 8b is press-fitted into the inner diameter surface of the axle housing 3, and the axial side surface 8C of the stepped portion is aligned in the axial direction of the axle housing 3. It is brought into contact with the side surface 3a. As described above, by preventing the nut 6 from rotating, using the jig 10 when press-fitting the impulse ring 7, and forming the outer diameter portion of the cover 8 into two stages, assembly with high positioning accuracy is possible.

ことが可能となる。Since the axle bearing rotation speed detecting device according to the present invention has the configuration as described in detail above, the impulse ring can be press-fitted later to tighten the nut, improving positioning accuracy and tightening the nut with the same speed as the NAND. The impulse ring can be set without disturbing the gap between the impulse ring and the sensor by moving in the axial direction, and the impulse ring also has the effect of sealing. Further, since the gap between the sensor and the concave and convex teeth of the impulse ring can be made small, and a large number of concave and convex teeth can be provided on the impulse ring, it is possible to improve the detection accuracy of the rotation speed.
