Definitions
- the present invention relates to a method for assembling a double-row tapered roller bearing device.
- FIG. 10 is a cross-sectional view of a double-row tapered roller bearing (conventional example 1) which has been widely used conventionally.
- Conventional Example 1 a plurality of tapered rollers 5, 5 roll between a single outer ring 1 having two outer raceways 2, 2 and a pair of inner races 4, 4 having inner raceways 3, 3. It is freely interposed.
- each of the inner rings 4, 4 is provided with a conical convex inner ring track 3, 3 corresponding to the outer ring track 2, 2.
- the tapered rollers 5, 5 are sandwiched between the inner races 4, 3 and the outer race 1 between the inner races 3, 3 and the outer races 2, 2, and are arranged at equal intervals by a retainer 6.
- Seal rings 7 and 7 are provided at both ends of the inner peripheral surface of the outer ring 1 and at ends of the outer peripheral surface of the inner rings 4 and 4.
- the seal rings 7, 7 seal the space between the outer ring 1 and the inner rings 4, 4, prevent foreign substances (dust, moisture, metal powder, etc.) from entering from outside, and prevent leakage of lubricant. Provided to prevent.
- the double-row tapered roller bearing of Conventional Example 1 as described above is assembled in the following procedure.
- the subassembly member 11 in which the retainer 6 and the tapered rollers 5 are combined is attached to the inner ring 4.
- This is inserted into the inner circumference of the outer ring 1 as shown in FIG. 12 so that the tapered rollers 5 match the outer ring tracks 2 and 2 and the inner ring tracks 3 and 3.
- seal rings 7 and 7 are attached between both ends of the inner peripheral surface of the outer ring 1 and ends of the outer peripheral surfaces of the inner rings 4 and 4, respectively.
- the retainer 6 is a pair of separated annular portions, ie, a large annular portion. Part 6a and the small annular part 6b, and a plurality of pillars 6c spanned between these two annular parts, and further, from the diametrically inner end of the small annular part 6b to the diametrically inward side. It has a substantially conical shape formed by an annular rib portion 6d extending toward the center. With this configuration, a plurality of trapezoidal window-shaped pockets 10 for accommodating the tapered rollers 5 are provided at equal intervals between the adjacent pillar portions 6c.
- FIG. 14 is a sectional view of the sub-assembly member 11 in which the tapered rollers 5 are arranged in the pocket 10.
- the tapered rollers 5 are arranged so as to fall into the pocket 10 from the inside in the diameter direction of the cage 6.
- FIG. 15 is a cross-sectional view of the column 6 c of the cage 6 in a plane perpendicular to the longitudinal direction.
- the placed tapered rollers 5 are indicated by imaginary lines. Since the space between the adjacent pillars 6c, that is, the circumferential width W10 of the pocket at each position on the generatrix of the tapered roller 5 is smaller than the diameter of the tapered roller 5 at each position, The tapered roller 5 remains in the pocket of the retainer 6 in a state of being dropped.
- the cage 6 only supports the tapered rollers 5 from the outside in the diameter direction. Therefore, in this sub-assembly member 11, the tapered rollers 5 do not fall out in the diameter direction, but depending on the posture of the sub-assembly member 11, the tapered rollers 5 fall down in the diameter direction. Will fall off.
- a cage having a structure in which the arranged tapered rollers fall off inward in the diameter direction, such as the cage 6, is a highly versatile cage, but has a drawback that the tapered rollers are easily dropped off.
- FIG. 16 shows an example of a conventionally known hub unit (conventional example 2).
- This structure is different from the conventional example 1 in that a flange 26 is provided at one end of the hub body 16 for supporting a wheel and the like. While forming a first inner raceway 28 for forming a row of tapered roller bearings, an inner race 35 having a second inner raceway 36 is externally fitted and fixed to the outer peripheral surface at the other end of the hub body. I'm going to do it.
- an assembling step of inserting the hap body 16 serving as the inner ring into the outer ring 13 in a state where the hap body 16 serving as the inner ring is combined cannot be employed as in the conventional example 1. That is, in the case of the conventional example 2 shown in FIG. 16, the flange 26 provided at one end of the hub body 16 becomes an obstacle. Seal ring 15 cannot be installed. Therefore, in this case, the sub-assembly member 19 in which the first row of tapered rollers 18 a is arranged in the first cage 17 is first installed on the first outer raceway 22 of the outer race 13, and then The first seal ring 15 is attached, and then the hap body 16 is inserted into the outer ring 13. Thus, in the case of the structure as in Conventional Example 2, it cannot be handled in a state where the hub body 16 serving as the inner ring is mounted on the sub-assembly member 19.
- the outer ring 13 on which the sub-assembly member 19 and the first seal ring 15 are mounted is attached to the bearing.
- the outer ring 13 and the hub main body 16 are combined so that the rotation center axis of the outer ring 13 is oriented vertically and the second outer ring track 23 is positioned above the first outer ring track 22.
- the reason for (1) and (2) is that workability is improved by moving the lighter side member and assembling it.
- FIG. 9 is a cross-sectional view of the column 17c of the first cage 17 of the second conventional example, and shows the held tapered rollers 18a by phantom lines.
- the cross-sectional pocket diameter ⁇ ⁇ W 17 on the inner side in the diameter direction of the first cage 17 is smaller than the cross-sectional diameter D 18 a of the tapered roller 18 a.
- the tapered rollers 18a are held so as not to fall inward in the diameter direction (for example, see Japanese Patent Application Laid-Open No. 2000-65049).
- a fall-off prevention cage such as the first cage 17 in the above-mentioned conventional example 2 is not versatile, a great deal of cost is required for manufacturing the cage.
- a structure that can be dropped inward in the diametrical direction such as the cage 6 of the conventional example 1, has the advantage that it can be mass-produced because of its versatility, and the production cost can be reduced.
- the problem that the tapered rollers come off is inevitable.
- the present invention provides a highly versatile and highly flexible housing having a flanged hub body by using only a cage without using a cage with low versatility and high cost.
- An object of the present invention is to provide an assembling method capable of assembling a double-row tapered roller rolling bearing device.
- the present invention for solving such a problem is as follows. That is, an outer race having a first outer raceway and a second outer raceway on the inner peripheral surface, an inner race having a second inner raceway facing the second outer raceway, and facing the first outer raceway A hap body having a first inner ring raceway, a flange protruding diametrically outward at one end, and a small-diameter cylindrical surface portion at the other end for externally fixing the inner ring. A plurality of first rows of tapered rollers provided between the first inner raceway and the first outer raceway, and a first retainer for arranging the first row of tapered rollers at equal intervals.
- a first seal ring provided at an end of the outer ring on the side of the first outer ring raceway comprising: a first seal ring provided at an end of the outer ring raceway side; And the first row of circles! /
- a step of producing a sub-assembly member by combining rollers, and the first row of cones in the sub-assembly member A step of press-supporting the tapered roller by internally fitting a retaining ring in a diametrically inward direction of the roller; a step of mounting the sub-assembly member on the first outer raceway of the outer race; and mounting the sub-assembly member.
- the retaining ring prevents the tapered rollers from falling off, so that in a double-row tapered roller bearing device having a flange of the hap body, a bearing device can be manufactured using a versatile cage. .
- the retaining ring is pushed out by the step portion of the hub body, the step of removing the retaining ring is not required.
- another invention according to the present application is a method for assembling the double-row tapered roller rolling bearing device, wherein the assembling method includes: a cylindrical main body; and an end in one axial direction of the main body.
- a hub body distal end contact portion extending radially inward, and a plurality of tongue pieces extending radially obliquely outward from the other axial end of the main body at a predetermined interval and provided to the sub-assembly member.
- a roller abutting portion having a roller abutting portion that abuts on the first row of tapered rollers in a state of being internally fitted, and a sub jig combining the first cage and the first row of tapered rollers.
- a step of producing an assembling member a step of fitting the holding jig inside a diameter direction of the first row of tapered rollers in the sub-assembly member to support the tapered rollers;
- the outer ring Mounting the first seal ring on the inner peripheral surface of the end of the outer ring on which the sub-assembly member is mounted, on the side of the first outer ring raceway; and a sub-assembly member.
- the hub body, the first seal ring, and the sub-assembly member are attached while pushing out the tip end contact portion of the hap body of the holding jig which is fitted in the hub body by the axial tip portion of the hub body.
- a step of combining the outer race with the outer ring is
- the holding jig prevents the tapered rollers from falling off.
- the roller contact portion of the holding jig extends obliquely outward in the radial direction. Therefore, it is possible to more stably support the tapered rollers along the tapered rollers of the first row that are placed in an inclined manner.
- a bearing device can be manufactured using a versatile cage. Further, since the holding jig is pushed out by the axial end of the hub body, a step of removing the holding jig is not required.
- the number of the roller contact portions of the holding jig is the same as the number of the tapered rollers in the first row, and the number of the tapered rollers of each roller contact portion is equal to the number of the tapered rollers.
- the contact surface is concave, and one of the roller contact portions supports one of the first row of tapered rollers. In this case, each of the individual tapered rollers in the first row comes into contact with a separate roller abutting portion, so that the corresponding abutting portion reliably contacts all the tapered rollers.
- the contact surface is concave, the support of the tapered rollers is more stable.
- the number of the roller contact portions of the holding jig is the same as the number of the tapered rollers in the first row, and the number of the tapered rollers of each roller contact portion.
