賞用されている。 Conventionally, in order to guide a linearly moving body of mechanical equipment, a sliding surface that slides against a slideway is formed on the moving body, and the moving body is engaged with the slideway to cause the moving body to move by overcoming sliding friction. A slide guide that circulates rolling elements is engaged with a linear raceway surface of a way to reduce the resistance of the moving body by rolling friction. Those that use sliding friction are prized for their ability to provide appropriate damping, the ease with which they can be operated by hand, and their ability to withstand low-speed heavy loads.

用を生じ、両者間の摩擦係数を増大させて円滑な
摺動を妨げるという欠点を有している。 The shape of a general sliding surface caused by this sliding friction is shown in FIG. 1 or 2, which is typical and widely used. Fig. 1 shows what is called a dovetail or dovetail sliding surface.A dovetail-shaped slideway 2 is formed on the machine base 1, and the slideway 2 and moving body 3 are horizontal surfaces 4, 5, slopes 6, 7.
They touch and engage in a sliding manner. In such a sliding surface, when the load applied to the moving body 3 is a downward load in the direction of arrow 8, the horizontal surfaces 4 and 5 carry the load, so the load capacity is large, but for an upward load in the direction of arrow 9, On the slopes 6 and 7, and in response to a horizontal load in the direction of arrow 11, a wedge effect is generated on the slopes 6 and 7 to support the load, increasing the coefficient of friction between the two and ensuring smooth sliding. It has the disadvantage of being a hindrance.

荷重は水平面４と斜面７もしくは水平面５と斜面
６にて坦持することになり、両者間に局部的な圧

させるという欠点を有している。 In particular, when a torque load due to a rotational moment in the direction of the arrow 12 is applied to the moving body 3, the load will be supported by the horizontal surface 4 and the slope 7 or the horizontal surface 5 and the slope 6, and there will be a local gap between them. This has the disadvantage of causing excessive pressure contact, or so-called uneven contact, which increases wear on the sliding surface.

を有している。 Fig. 2 shows what is called a square guide, in which square guides 13, 13 are provided on both sides of the upper surface of the machine base 1, and the moving body 3 is allowed to slide on the upper surface 14, lower surface 15, and side surface 16. engage. It is assumed that a load is applied to the moving body 3 in the same direction as shown in FIG.
For downward load of arrow 8, upper surface 14, arrow 9
For an upward load of 15, the lower surface 15, and arrow 1
For the horizontal load shown in Fig. 1, the side surfaces 16 support the load from the normal direction, so the friction coefficient does not increase as much as in Fig. 1, but the torque load due to the rotational moment shown by the arrow 12 acts on the moving body. In this case, similar to the one shown in FIG. 1, there is a disadvantage that a local pressure contact portion is created between the two, increasing wear in that portion.

考案が提案されているが、このものは運動体に作
用する負荷をすべてローラで坦持するもので負荷
能力が小小さいという欠点を有している。 As described above, with the conventional sliding surface shape, at least the torque load due to the rotational moment whose center is parallel to the direction of motion of the moving body generates a concentrated load on the guide surface due to one-sided contact, increasing wear on the part. This has the disadvantage that it prevents smooth sliding over a long period of time. In addition to the above-mentioned conventional example, a slide guide using rollers in the sliding part has been proposed, for example, in Japanese Utility Model Application Publication No. 53-108677. All of the components are supported by rollers, which has the disadvantage of a small load capacity.

イドを提供することを目的とするものである。 This invention is a sliding guide surface that guides the linearly moving body of the above conventional example, and can support the torque load centered on the direction of motion of the moving body without causing uneven contact, so that it can handle loads in all directions. The object of the present invention is to provide a slide guide having a slide guide surface with a large load capacity.

When energized, the moving body 3 moves the guide surface 19 of the slideway 17 on the sliding surface member 22 of the liner 23.
A sliding member 26 that is in sliding contact with and fixed to the moving body 3
The circular arc portion is engaged with the circular arc guide concave surface portion 21 and slid. At this time, the downward load is supported by the contact between the flat guide surface 19 and the sliding surface member 22, and between the sliding member 26 and the arcuate surface below the horizontal line passing through the center of the inner arc of the arcuate guide concave portion 21, and is carried upward. The sliding member 26 supports the load on the upper side of the arc guide concave portion 21. The horizontal load is carried by the circular arc guide concave portion 21 and the horizontal projection surface portion of the sliding member 26. The sliding surface member 22 comes into contact with the vicinity of one end of the flat guide surface 19 against the torque load due to the rotational moment about the movement direction of the moving body 3, and the sliding surface member 22 and the flat guide surface 19 The sliding member 26 is in contact with and supported by the arcuate guide concave portion 21 and the sliding member 26 located below the side in contact with and the side away from.

いる方が有利である。 Therefore, if the moving body 3 and the liner 23 are brought into contact with each other with a circular arc surface as shown by the two-dot chain line A in FIG. Contact with can and may prevent uneven hitting. However, in this embodiment, the surfaces of the moving body 3 that are in contact with the upper surface of the liner 23 are both flat. The reason for this is that by tightening the bolt 33, the inside of the side member 24 is deflected, and the sliding member 26 and the arc guide concave portion 2 are bent.
1, the upper half of the sliding member 26 on one side and the upper side of the circular guide concave part 21, and the lower half of the sliding member 26 on the other side and the lower part of the circular guide concave part 21 against the torque load. The torque load is evenly distributed on the sides, and the uneven load between the flat guide surface 19 and the sliding surface member 22 is alleviated. Therefore, it is desirable that the length of the contact portion l between the sliding member 26 and the circular arc guide concave portion 21 and the central angle of the circular arc at that portion be large, and it is advantageous that the center line C already drawn is inclined to widen downward. be.

調整ができる。 As mentioned above, this idea is a slideway 17
The upper surface of the protruding portion 17b is made flat, the lower surface of the protruding portion is a circular guide concave portion 21, and both corners formed by the lower surface and side surfaces of the protruding portion 17b are circular guide concave portions 21, The moving body 3 is brought into sliding contact with the slide guide surface 19 of the slideway 17 via the liner 23, and is also brought into sliding contact with the arcuate guide concave surface portion 17b of the slideway 17 via a sliding member 26 having an arcuate portion. The arc guide concave part 1
In 7b, the openings of the arcs are directed diagonally downward, which are opposite to each other, and the arc portions are located below the horizontal line passing through the center of the arc, so that the horizontal and vertical forces acting on the moving body 3 and the moving body It has a large ability to support a torque load centered on the direction of motion of the moving body 3, and always slides smoothly without causing local pressure contact against loads in all directions that act on the moving body 3. This has the effect of making it possible to Therefore, slideway 1
Even if there is only one number 7, the torque can be maintained. Grinding of the arc guide concave surface portion 21 is easy. Since the base portion 17a at the bottom of the slideway 17 can be extended to both sides, the slideway 17 can be stably attached. Since an adjustment device for the sliding member 26 is provided, the gap can be adjusted.
