双方に不要な歪が生じろという問題があった。<Problems to be Solved by the Invention> However, the conventional hub unit has a pulser ring 57 having the outer ring member 52 and the detected portion 56 as described above.
is provided separately from the outer ring member 52, and a pulser ring 57 provided separately from the outer ring member 52 is connected to the end portion 50a of the main body portion 50 of the outer ring member 52.
By press-fitting into the outer periphery, the detected portion 56 is provided on the outer ring member 52 side to be detected by the rotation detector, so when the pulser ring 57 is press-fitted into the outer ring member 52 and fixed, the outer ring member 52 There is a problem in that unnecessary distortion occurs in both the pulser ring 57 and the pulser ring 57.
外輪部材５２に歪が生じろと軌道面５２ａ、５２ａが変

心精度を一定以上確保することができなかった。Further, when the pulser ring 57 is strained, the outer diameter of the pulser ring 57 is strained, and the accuracy of the gap between the pulser ring 57 and the rotation detector is reduced, causing a reduction in rotation detection accuracy. Furthermore, since the conventional hub unit has a structure in which the pulser ring 57 is externally fitted and fixed to the end portion 50a of the outer ring member 52, there is a problem in that the outer diameter of the detected portion 56 becomes large. . Further, in the conventional hub unit, the outer ring member 52 and the pulser ring 57 are assembled after finishing each side to a predetermined shape and size, as described above, so it is easy to assemble the outer ring member 52 after assembly. It was not possible to ensure a certain level of concentric accuracy between the orbital surfaces 52a, 52a and the outer peripheral surface 56b of the detected portion 56 of the pulser ring 57.

外径を小さくできろハブユニット提供することにある。An object of the present invention is that there is no need for press-fitting as in the conventional hub unit, and therefore the raceway surface of the outer ring member and the detected part are not distorted, and the raceway surface of the outer ring member is not distorted by - times of chucking. By machining the outer peripheral surface of the detected part, it is possible to easily ensure high concentric accuracy between the raceway surface and the outer peripheral surface of the detected part, and furthermore, the outer diameter of the detected part can be reduced. It is about providing.

寸法を従来に比へて小さくできる。Effects> On the outer periphery of the main body part itself of the outer ring member, detection portions consisting of a plurality of protrusions projecting in the radial direction at regular intervals in the circumferential direction are integrally formed. Therefore, when assembling the hub unit, unnecessary distortion of the outer ring member and deviation of the outer diameter of the detected portion, which occur when conventional pulser rings are press-fitted, do not occur. Therefore, since external fitting is not required, the outer diameter of the detected portion can be made smaller than in the past.

が取り出される。A reference portion for machining the raceway surface and the outer circumferential surface of the detected portion concentrically is provided on the opposite side of the detected portion across the flange portion of the main body portion of the outer ring member. With this reference portion still chucked, the raceway surface of the outer ring member and the outer circumferential surface of the detected portion are processed concentrically and simultaneously in one chuck. For this reason. - The raceway surface of the outer ring member and the outer circumferential surface of the detected portion are easily machined concentrically with much higher precision than in the past. However, since there is no press-fitting process like in the past, the concentric precision achieved will not be distorted or lost. In this way, the raceway surface of the outer ring member and the outer circumferential surface of the detected part are machined concentrically with high precision, so when the outer ring member rotates to the inner ring part via the rolling elements, the detected part will not run out. I don't do it. Therefore, the gap between the rotation detector, which is disposed to face the detected part with a constant gap in the radial direction, and the detected part is always kept constant. Therefore, the rotation detection accuracy of the rotation detector is ensured,
A signal corresponding to the rotation speed of the outer ring member is stably extracted from the rotation detector.

法（第１図中り参照）の狂いが生じることは全くない。In this way, this hub unit does not press-fit a pulser ring provided separately into the outer ring member and provide a detection portion on the outer ring member side as in the conventional case, but instead provides a detection portion on the outer ring member side. Since the detected portion 1O is integrally formed on the outer periphery of the device itself, the press-fitting process unlike the conventional method is not required when assembling the device. Therefore, when assembling this hub unit, there will be no unnecessary distortion of the outer ring member or deviation of the outer diameter dimension of the detected part (see the middle part of Figure 1), which occurs when conventional pulser rings are press-fitted. .

ることができる。Therefore, the outer ring portion 11 of this hub unit has a much higher degree of concentricity between the raceway surfaces 7, 7 and the outer peripheral surface 10b of the test peak lO than in the conventional case. Moreover, since there is no press-fitting process as in the conventional case, the obtained concentricity will not be disturbed later. Therefore, in the hub unit incorporating this outer ring member 1, when the outer ring member 1 rotates around the inner ring member 4 via the balls 5 and 6, the detected portion 10 does not swing. Therefore, according to this hub unit, the gap between the rotation detector and the detected portion 10 described above can always be kept constant, and high rotation detection accuracy can be stably ensured.
なお、被検出部および加工基準部はト記実施例のものに
限らないのはいうまでもない。It goes without saying that the detected portion and the processing reference portion are not limited to those in the embodiment described above.

従来に比べて小さくできる。<Effects of the Invention> As is clear from the above, the hub unit of the present invention has the following effects:
Instead of press-fitting a separate pulser ring into the outer ring member and providing a peak to be detected on the outer ring member as in the past, the detection part is integrated into the outer periphery of the main body of the outer ring member itself. When assembling it,
There is no press-fitting process like in the past. Therefore, according to the hub unit of the present invention, when assembling the hub unit, there is no unnecessary distortion of the outer ring member or deviation of the outer diameter of the detected portion, which occurs when a conventional pulser ring is press-fitted. Furthermore, since external fitting is not required, the outer diameter of the detected portion can be made smaller than in the past.

確保することができる。Further, the outer circumferential surface of the test peak of the outer ring member of the hub unit of the present invention is concentric with the raceway surface. Moreover, since press-fitting as described above is not required, the concentricity between the outer circumferential surface of the detected portion and the raceway surface will not be distorted due to distortion. Therefore, according to the hub unit of the present invention, when the outer ring member rotates toward the inner ring member through the rolling elements, the detected part does not run out, so the gap size between the rotation detector and the detected part is always kept constant. It is possible to maintain constant dimensions and ensure high rotation detection accuracy.

By concentrically machining and simultaneously machining the outer circumferential surface of the detected part, the raceway surface of the outer ring member and the outer circumferential surface of the detected part can be concentrically machined with much higher precision and easier than before. I can do it.
