ベアリング組立体からの潤滑剤の洩れを防止するため
に、通常シール装置が取付けられる。In this type of bearing, there is an axial clearance between the bearing assembly and the way, that is, a clearance between both end surfaces of the bearing assembly and the way, and a vertical clearance, that is, the side surface of the way and the bearing assembly. A gap is formed between the solid and the solid body, and a seal device is usually attached to prevent foreign matter such as dust from entering through the gap and leakage of the lubricant from the bearing assembly.
従来、この種シール装置として、実公昭62−43136号公
報に示されるものは、第５図乃至第７図に示すように、
一対の側板51,51及び連結梁52,52にゴム53が固着されて

よって異物の侵入及び潤滑剤の洩れを防止している。Conventionally, as a sealing device of this kind, the one disclosed in Japanese Utility Model Publication No. 62-43136 is as shown in FIGS. 5 to 7.
The seal device 50, in which the rubber 53 is fixed to the pair of side plates 51, 51 and the connecting beams 52, 52, is attached to the bearing assembly to prevent foreign matter from entering and lubricant from leaking.

製作コストも高くつくという問題があった。However, in manufacturing the sealing device 50, first, a flat plate is press-molded, rubber is baked and fixed to the plate, and then the plate is bent as shown in the figure, so that the rubber baking step is performed during machining. And the process to complete is complicated,
There was a problem that the manufacturing cost was high.

を解決した。Means for Solving the Problems The present invention is to integrally form a seal member for sealing an axial gap and a vertical gap between a bearing assembly of a linear motion bearing and a way, and to the bearing assembly. A sealing device for a linear motion bearing in which the seal member is housed in a formed step portion and is attached to the bearing assembly by a holding plate provided separately with the seal member, wherein the seal member is movable within the step portion. The above-mentioned problem is solved by the sealing device characterized by the following.

り簡便になる。Function Since the seal member of the present invention is separate from the holding plate, it can be manufactured by separate manufacturing processes. The seal member is not restricted by the bearing assembly and the holding plate, and moves to a certain extent in the step portion to have an appropriate positional relationship with respect to the rail, so that a troublesome position adjustment when mounting the seal member is required. Is unnecessary, and the tightness with the way is improved. Further, in the configuration of claim 2, since the step portion for accommodating the holding plate is provided further outside the step portion for accommodating the seal member, the attachment of the retaining plate to the bearing assembly becomes easier.
実施例 以下、図面を参照し、本考案の実施例を説明する。Embodiments Embodiments of the present invention will be described below with reference to the drawings.

The intermediate member 23 located between the upper member 22 and the lower member 24 has an opposing J-shaped groove for forming an upper ball circulation path on the upper surface in cooperation with the bearing body 21 and the upper member 22 and its opposing J-shaped groove. On the lower surface, a ball holding groove for connecting the J-shaped tip ends is connected to the opposing J-shaped groove for forming a lower ball circulation path together with the lower member 24 on the lower surface. A ball holding groove is formed.
そして、これら上側及び下側ボール循環路にボール25が

詳しく説明されているので、詳しい説明は省略する。Since the structure of such a ball bearing for linear movement itself is not the gist of the present invention but is described in detail in Japanese Patent Application No. 63-162600, detailed description will be omitted.

段部Ａに対して軸方向にさらに外側にある。Two step portions 22a, 23a, 24a and 22b, 23b, 24b are formed on both end surfaces of the upper member 22, the intermediate member 23 and the lower member 24, respectively, as shown in FIG. When the two members are assembled, their respective step portions are coincident with each other to form two step portions A and B for receiving the later-described portion 16a of the sealing member 16 and the front portion 14a of the holding plate 14. Note that the stepped portion B is located further outside in the axial direction than the stepped portion A.

The seal member 16 and the holding plate 14 are fitted and assembled to the 0, 31 to complete the bearing assembly 12. The step 31 is the step 30
Is further outward in the vertical direction.

The bearing assembly 12 and the way 11
A gap is formed between the and in the axial direction (that is, the linear movement direction) and in the vertical direction. The seal member 16 includes a pair of front plates 16a, 16a for sealing the axial gap and connecting beams 16b, 16b for sealing the vertical gap.

16 is a size and shape that can be slightly moved in the stepped portion 30 and the stepped portion A, or the stepped portion 30 and the stepped portion A are such sizes, and the holding plate 14 is fixed to the bearing assembly 12 by the bolt 18.
Even after they are attached to each other, the movement between them is not completely restricted. Moreover, by molding the inner edge of the front plate 16a to be slightly smaller than the outer edge of the raceway 11, the sealing member 16 grips the raceway 11 by its elasticity, and the gripping force acts evenly to ensure the axial gap. Close to. Further, as shown in FIG. 3, a lip 16c is formed in a portion in contact with the side surface of the raceway 11, and this lip seals the vertical gap.

果はリップ16cの部分において特に顕著である。The holding plate 14 is usually made of metal and not only holds the sealing member 16 but also protects it. Conventionally, since the bending process is performed last, only a material having a large elastic deformation amount such as rubber can be used.
However, by providing the seal member 16 as a separate body from the holding plate 14 for mounting, the holding plate 14 can be manufactured independently without going through different intermediate processes such as a rubber fixing process. As a result, the seal member 16 is also independently manufactured, and only the final assembly to the bearing assembly 12 is required, which significantly reduces the number of manufacturing steps for each. Along with this, the applicable range of the material of the seal member 16 is expanded, and in particular, the resin can be molded by one injection molding, and the molding accuracy thereof is improved as compared with that of the rubber material. This effect is particularly remarkable at the portion of the lip 16c.
そして、シール部材16を、前述のように段部内に収納す

軸方向及び上下方向の密閉力に偏りが生じることなく、
リップ16cも軌道台11と均等に接し、取付時に面倒な調
整を必要としない。When the seal member 16 is housed in the stepped portion as described above, some movement is allowed even if it is attached to the bearing assembly 12 by the holding plate 14, so that the bullet portion 30 and the stepped portion are provided as in the present embodiment. Simply inserting the seal member 16 into the portion A causes the seal member 16 to move into an appropriate positional relationship by itself.
There is no bias in the sealing force in the axial and vertical directions,
The lip 16c also makes uniform contact with the rail 11 and does not require troublesome adjustments when mounting.

る。In the present invention, in addition to the bearing body, the upper member,
Although the embodiment has been described as a linear motion bearing including an intermediate member and a lower member, the scope of application of the present invention is not limited to such a linear motion bearing. It is of course applicable to a linear motion bearing 10 'having a general structure as shown in FIG. 4, and in this case, in order to store the seal member in the stepped portion, as in the above-mentioned embodiment,
A step portion is provided on both end surfaces of the return cap and the lower surface of the leg portion of the bearing body, and the seal member is fitted into the step portion.
考案の効果 本考案は、以上のように、シール部材と保持板とを別体
とすることにより、製作及び組立コストの削減ができ、
さらに、シール部材も高精度に製作することができるよ
うになった。Effect of the Invention As described above, the present invention can reduce manufacturing and assembling costs by separating the seal member and the holding plate from each other.
Furthermore, the seal member can be manufactured with high precision.

する。Further, since the seal member is not restricted by the bearing assembly and the holding plate, it moves to a certain extent within the step portion and becomes an appropriate positional relationship with respect to the rail, so that a troublesome position adjustment when mounting the seal member is required. Is unnecessary, and the sealing property with the way is improved.
