Due to the gap, there is no contact. Therefore, the pulser ring does not shift in position when the inner ring members on both sides are assembled and during bearing operation, and the gap between the sensor and the pulser ring is always constant. In addition, in a bearing unit in which two split inner ring members are butted together via a spacer, the pulser ring is press-fitted and fixed to one split inner ring member in the same manner as described above and positioned in the axial direction, and the pulser ring is positioned in the axial direction by the spacer and the other It is in a non-contact state with the divided inner ring member due to the gap. Therefore, as described above, the gap between the sensor and the pulser ring is always constant. EXAMPLES The present invention will be described in detail below with reference to illustrated examples. As shown in FIG. 1, the hub unit bearing 10 for an automobile wheel includes roller members 13 as transfer members on both sides in the axial direction between two abutted annular divided inner ring members 11a and llb and an outer ring member I2. .13 are rotatably provided in double rows. The outer ring member 12 is fixed to the vehicle body (suspension) side, and the split inner ring members 11a and 1 lb have an axle 14
is fitted. The two divided inner ring members 11a and 1lb are butted against each other at their inner ends 11c and IId,
Small-diameter step portions 11e and IIf having the same diameter and continuous to each other are formed in the inner end portions 11c and Ild, respectively. On the other hand, the pulser ring 15 that is fitted into the small-diameter step portions lie and Iff is a bevel gear-shaped one in which concave and convex portions (detected portions) are formed on the conical outer peripheral surface at equal intervals in the circumferential direction. W, is the inner ring member 11a on both sides, l l
Small diameter stepped portion 11.b. The gap t is larger than the width W1 between e and llf.
The dimension W is narrower by 1. Then, the pulser ring 15 has its negative end surface 15a abut against the shoulder portion 11h of the small diameter stepped portion 11f of one divided inner ring member 11b, and the small diameter inner circumferential surface 15c having the same width W3 is brought into contact with the small diameter stepped portion 11f.
The other end surface 15b of the pulser ring I5 is spaced apart from the shoulder 11g of the small diameter stepped portion lie of the other split inner ring member 11a by the gap tI. There is. Further, a gap tt is formed between the large-diameter inner circumferential surface 15d of the pulser ring 15 that follows the small-diameter inner circumferential surface 15c and the outer circumferential surface of the small-diameter stepped portion lie of the other divided inner ring member 11a. Note that the other divided inner ring member 11a does not necessarily have to be formed with the small diameter stepped portion lie, and when the small diameter stepped portion lie is not formed, the large diameter inner circumferential surface 15d of the pulser ring I5
The diameter may be made larger so as not to contact the outer periphery of the inner end portion 11c. A sensor insertion hole 12a that is inclined with respect to the axis thereof is provided through the outer ring member 12, and a sensor 16 is inserted into the insertion hole 12a so as to face the outer circumferential surface of the pulser ring 15 from a substantially perpendicular direction. can be installed. The hub unit bearing IO having the above configuration is assembled as follows. First, the roller member 13 and the like are fitted onto one of the divided inner ring members 11b, and the pulser ring 15 is fitted onto the small diameter stepped portion 11f of this divided inner ring member 11b. Next, this split inner ring member Ilb is assembled into the outer ring member 12 (, 5).Furthermore, the other split inner ring member 11a, to which the roller member I3 and the like are similarly fitted, is assembled into the outer ring member 12. By t 1 and t 2, the other divided inner ring member 11a does not come into contact with the pulser ring 15 at all, so no positional deviation occurs in the pulser ring 15. Therefore, the positional accuracy of the assembly of the pulser ring 15 is improved, and the sensor I6 and the pulser ring The gap g between the hub unit bearing 15 and the hub unit bearing 15 can be accurately maintained at a constant dimension.Furthermore, when the outer ring member 12 and the inner ring member 11 of the thus assembled hub unit bearing 10 are fixed to the vehicle body and the inner ring member 11 is respectively fixed to the axle and the bearing is operated, the pulser ring 15 Since it is positioned, press-fitted and fixed in the bearing direction only to one inner ring member zb, the pulser ring 15 does not shift in position, unlike the conventional example in which it is press-fitted and fixed to the inner ring member.
Similarly, the gap g between the pulser ring 15 and the sensor 16 can be maintained at a constant dimension. Furthermore, both inner ring members 11
Decomposition of a and 11b can be easily carried out by reversing the above procedure,
If only the other divided inner ring member 11b is removed,
Balsa ring 15. The gap size between the sensor 16 and the sensor 16 can also be easily confirmed. In addition, in the above conventional example, the other end surface 1. of the balsa ring I5.
5b and the shoulder portion 11 of the small diameter stepped portion of the other split inner ring member 11a
Since the gap t1 is also formed between the balsa ring 15 and the balsa ring 15, the difference in width of the balsa ring 15 may be large, and there is an advantage that manufacturing becomes easy. FIG. 2 shows the two divided inner ring members 11a of FIG. 1. 11b shows another embodiment of the bearing unit in which the bearing units 11b and 11b are butted together with a spacer 21 interposed therebetween. This hub unit bearing 20 has the spacer 21 and the width of the small-diameter inner circumferential surface 15c of the balsa ring 15 set to W4, which is equal to that of the small-diameter stepped portion 11f of one divided inner ring member 11b, and the small-diameter inner circumferential surface 1
Large diameter inner peripheral surface +5d following 5c and the other divided inner ring member 11
The point where a gap t is formed between a and the spacer 21 is the first point.
The same numbers are given to the same parts that are only different from the hub unit bearing shown in the figure. In this hub unit bearing 20 as well, the balsa ring 15 is
Because it is axially positioned, press-fitted and fixed to only one split inner ring member IIb, and is in a non-contact state with the spacer 21 and the other split inner ring member 11a due to the gap t,
The same actions and effects as described in FIG. 1 are achieved.
以上の説明より明らかなように、本発明の軸受ユニット

Since the other split inner ring member and spacer are not in contact with each other, the balsa ring does not shift when installing the split inner ring member or during bearing operation, and the gap between the sensor and the balsa ring can be accurately adjusted. In addition to being able to maintain constant dimensions,
It is also possible to easily confirm the gap size when assembling the divided inner ring members and to easily disassemble the divided inner ring members.
