設ける必要がある。[Detailed Description of the Invention] The present invention relates to a sealing device for a ball bearing for linear operation. Linear motion ball bearings have applications in machine tools, industrial robots, etc., and are ball bearings used in reciprocating parts. This type of ball bearing also needs to be provided with an appropriate sealing device to prevent lubricant leakage and foreign matter from entering from the outside.

であるため、部品点数の増加を招き、且つ密閉性
も劣る欠点を有している。 Conventionally, there is a sealing device used for this type of device as shown in Japanese Patent Publication No. 57-38812, but the side plate with the rubber seal attached for sealing in the axial direction and the bottom plate for sealing in the vertical direction are separate bodies. Since the structure is fixed with screws or the like, the number of parts increases and the airtightness is also poor.
本考案は、従来装置の上記のような欠点を除去
することを目的としてなされたもので、軸方向を
シールするシールを取付けた一対の側板と上下方

一体構造に形成したことを特徴とする。 The present invention was developed with the aim of eliminating the above-mentioned drawbacks of conventional devices, and consists of a pair of side plates fitted with seals for sealing in the axial direction and a pair of bottom plates fitted with seals for sealing in the vertical direction. It is characterized by being formed into an integral structure.

シール装置が取付けられる。 Embodiments of the present invention will be described below based on the accompanying drawings. In FIGS. 1 and 2, 1 is a track base, 2 is
3 is a ball, 3 is a bearing body, and a pair of return caps 4, 4' having ball deflection grooves are attached to both ends of the bearing body 3, and the integrated structure of the present invention is shown by reference numeral 10 on the outside thereof. A sealing device is installed.

を有している。 FIG. 3 is a perspective view showing details of the sealing device, in which a seal 11b is fixed to the metal plate 11a in a substantially U-shaped opening of the pair of side plates 11 in a shape that matches the outer shape of the track base 1. As shown in FIG. 5, the pair of bottom plates 12 have a seal 12b having a rhombic cross section fixedly attached to the upper side of a metal plate 12a. Reference numeral 13 denotes a mounting hole for mounting the side plate 11 to the return caps 4, 4', and has a cross section as shown in FIG.

り、極めて好都合である。 The distance between the pair of side plates 11 is the distance between the bearing body 3
Since the length in the axial direction is the same as that of the pair of return caps 4, 4' attached to the bearing body, in order to install the sealing device of the present invention, first attach the return caps 4, 4' to the bearing body, and then attach the return caps 4, 4' to the bearing body. The sealing device 10 is fixed to the return caps 4, 4' from below with mounting screws. In this case, the bearing body 3 and return caps 4, 4'
If a groove 14 is provided on the inside of the lower surface of the bearing body, as shown in FIG. 7, and has a shape suitable for the bottom plate 12 having a rhombic cross section, it is possible to separately fix the bottom plate 12 to the bearing body 3 or the return caps 4, 4'. Even without this, since a lateral force always acts on the rhombic bottom plate 12 from the track 1, the bottom plate 12 is always pressed upward by the action of the grooves 14, which is very convenient.
勿論ベアリング本体３及びリターンキヤツプ
４，４′に設ける底板１２の取付け溝は第８図
ａ，ｂに示すように通常の角型でもよいがこの場
合にはねじ、リベツト等のような何等かの固着手
段を通常必要とする。 Of course, the mounting grooves of the bottom plate 12 provided in the bearing body 3 and the return caps 4, 4' may be of a normal square shape as shown in FIGS. Fastening means are usually required.
なお、一対の側板１１の内面全体にシールを設
けることが必要になつた場合は、第９図、第１０
図に示すような構成とし、特に取付孔１３に対し
てはシール部分のみが圧縮されることがないよう
な構成とする。 In addition, if it becomes necessary to provide a seal on the entire inner surface of the pair of side plates 11, please refer to FIGS. 9 and 10.
The configuration is as shown in the figure, and in particular, the configuration is such that only the sealing portion with respect to the attachment hole 13 is not compressed.
シールの材質としては、ゴム、フエルト、樹脂
