効な直線ころがり案内の軌道体支持方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for supporting a track body of a linear rolling guide that is effective when applied to guide surfaces such as sliding parts of precision instruments.
直線ころがり案内は、すべり案内に比較して摩擦抵抗が
少く軽く動かすことができ、また直進の精度も比較的良

ので、油膜の形成が薄く、油の粘性による減衰効果が小
さい。したがって、機械のベッドやコラムの基本構造に
充分な剛性を持たせないと切削、研削性能が低下してし
まう。Linear rolling guides have the advantage of having less frictional resistance than sliding guides and can be moved easily, and have relatively good straight-line accuracy. However, since rolling guides use balls and rollers, the oil film is thin and oil The damping effect due to viscosity is small. Therefore, unless the basic structure of the machine bed and column has sufficient rigidity, cutting and grinding performance will deteriorate.
第３図に示すように、従来の直線ころがり案内の軌道体
１（、ベアリング２の軌道体１）は、単にボルト３を介
してベース４に固定し、支持するだけであった。As shown in FIG. 3, the conventional linear rolling guide raceway body 1 (or the raceway body 1 of the bearing 2) is simply fixed to a base 4 via bolts 3 and supported.

軌道体を固定するものである。In order to achieve the above object, the present invention arranges the lower part of the raceway body with unevenness in the dovetail groove formed on the base, screws the raceway body to the base, and then closes the gap between the dovetail groove and the raceway body. The molded material is filled and cured, and the track body is fixed to the base.
そして、軌道体が注型物（たとえば、高分子化合物）を
介してベースに支持されることにより、注型物の減衰性
が軌道体に作用し、直線ころがり案内の減衰効果を高め
直線ころがり案内の精密機械えの使用を可能にした。By supporting the raceway body on the base via the cast material (for example, a polymer compound), the damping properties of the cast material act on the raceway body, increasing the damping effect of the linear rolling guide. This enabled the use of precision machinery.
以下、図面を参照して本発明の詳細な説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.

の硬化性高分子化合物である。FIG. 1 is a longitudinal sectional view showing an embodiment of the method for supporting a track body for a linear rolling guide according to the present invention, and numerals 2 and 3 in the figure are the same as those in FIG. 3. 1 and 4 respectively show a track body and a base similarly to Figure 3, but in the present invention, a leg part 6 in which a plurality of grooves 5 are formed is provided in the lower part of the track body 1, and the base 4 is provided with a dovetail. A groove 7 is provided. 8 is a cast material, which is made of a hardening polymer compound such as plastic concrete or synthetic resin having an appropriate strength.

なる。That is, in the method of the present invention, a raceway body 1 having a leg part 6 with a plurality of grooves 5 formed in the lower part is inserted into a dovetail groove 7 provided in a base 4, and 4 using bolt 3. Next, the gap between the dovetail groove 7 and the leg portion 6 is filled with a curable polymer compound 8. When the curable polymer compound 8 hardens, the lower part of the track body 1 and the base 4 are fixed via the compound 8, and the track body 1 is supported.
高分子化合物は、加えられる力と発生する歪（変形）と
の関係が金属とは異なって線形ではなく、大きなヒステ
リシス特性を有しているので、振動的な外力に対しては
金属に比較して１０〜１００倍の減衰性を有する。Unlike metals, the relationship between applied force and generated strain (deformation) is not linear in polymer compounds, and they have large hysteresis characteristics, so they are more resistant to vibrational external forces than metals. It has 10 to 100 times more attenuation.
し九がって、直線ころがり案内単体では減衰性が低くて
