造のものが知られている。Conventionally, this type of linear sliding bearing is provided with a slide guide fitting part on the lower surface side, and a load ball groove is formed on the inner wall of this slide guide fitting part in the longitudinal direction, and on the outside of this load ball groove. The slide body with the unloaded ball raceways formed on the front and rear end surfaces of the slide body by contacting and fixing a pair of lid plates having guide grooves that communicate with the loaded ball grooves and the unloaded ball raceways to form an endless ball raceway. There is known a structure in which the balls formed and arranged in the ball endless track of the slide are engaged with the transfer groove formed on the outer surface of the slide guide, and the slide is slidably provided with respect to the slide guide. .

計しなければならない。即ち、スライドの負荷ボール溝
・無負荷ボール軌道と案内溝とが正しく突き合わされ、
ボールがスムーズに転送されるように精密に製作しなけ
ればならない。However, such a linear sliding bearing must, of course, be designed so that sliding can be performed as smoothly as possible. That is, the loaded ball groove / unloaded ball track of the slide and the guide groove are correctly butted,
It must be manufactured precisely so that the ball can be transferred smoothly.
この突き合わせを正しく行う手段として特公昭62-11215

に配慮している。As a means to perform this matching correctly, Japanese Examined Patent Publication No. 62-11215
Although a linear sliding bearing according to No. 1 has been proposed, the present invention forms the opening end edge of the unloaded ball raceway of the slide body in a taper engaging portion that expands outwardly. By providing a wedge engaging portion that fits into the taper engaging portion at the end of the guide groove of the cover plate, the slide body and the cover plate are fitted together when they are fastened, and both slide. Consideration has been given to ensure accurate matching without moving.
しかし、この特公昭62-11215号に係る発明は次の欠点が
ある。However, the invention of Japanese Patent Publication No. 62-11215 has the following drawbacks.
スライド本体と蓋板とのズリ動防止は左右のクサビ係
合部が一対となってはじめてずり動防止が果たされるも
ので、言わば１個のずり動防止機構が存在するに過ぎな
い。In order to prevent the sliding movement between the slide body and the lid plate, the sliding movement is prevented only when the left and right wedge engaging portions form a pair, and so to speak, there is only one sliding movement preventing mechanism.
蓋板に形成したクサビ係合部は強度的に弱く、組み立
てに際して例えば蓋板を落としたりすると折損したり変
形したりし、テーパー係合部による係合が不良となる。The wedge engaging portion formed on the lid plate is weak in strength, and when the lid plate is dropped during assembly, for example, the wedge engaging portion is broken or deformed, and the engagement by the tapered engaging portion becomes poor.
スライド本体の無負荷ボール軌道の開口端縁と蓋板の
案内溝との連結部に段差が生じ易く、ここに段差が少し
でもあると一番重要なボールの転送が円滑に行なわれな
くなる。A step is likely to occur at the connecting portion between the opening edge of the unloaded ball track of the slide body and the guide groove of the cover plate, and if there is any step, the most important ball transfer will not be carried out smoothly.
本発明は、スライド本体と蓋板とを単なる付設でなく、
雄雌による係合付設するという着想においては従来例と
は異なるところはないが、雄雌による係合付設の箇所を
前記諸々の問題が生じる無負荷ボール軌道の開口端縁を
利用せず、負荷ボール溝と無負荷ボール軌道との間を利
用することでスライド本体と蓋板との合致を両者がズリ
動することなく正確にし、ボール無限軌道内をボールが
スムーズに転送し得る直線摺動用ベアリングを提供する
ことを課題とするものである。The present invention does not simply attach the slide body and the cover plate,
There is no difference from the conventional example in the idea of engaging attachment by male and female, but the location of engaging attachment by male and female does not use the open edge of the unloaded ball raceway that causes the various problems described above, By using the space between the ball groove and the unloaded ball raceway, the slide body and the lid plate can be matched accurately without the two sliding, and the ball can be smoothly transferred within the ball endless raceway. The challenge is to provide.
添付図面を参照して本発明の構成を詳述すると次の通り
である。The configuration of the present invention will be described in detail with reference to the accompanying drawings.

本発明は上述のように構成したから次の効果を有するこ
とになる。Since the present invention is configured as described above, it has the following effects.
1.スライド本体並びに蓋板に設けた左右の係合部２箇所
により両者を当接止着するから両者のずり動が確実に防
止し得ることになる。1. Since the left and right engaging portions provided on the slide body and the lid plate contact and fix the both, it is possible to reliably prevent the sliding movement of the both.
2.係合部をボール無限軌道の開口端縁に設けず、負荷ボ
ール溝と無負荷ボール軌道との間に設けたから、ボール
無限軌道に従来例の段部等の変形も生ぜず、ボール無限
軌道内をボールが支障なくスムーズに転送し得る。2.Because the engaging part is not provided at the opening edge of the ball endless track but between the loaded ball groove and the unloaded ball track, the endless ball track will not be deformed and the endless ball will not be deformed. The ball can smoothly transfer in the trajectory.
3.係合部は湾曲係合凸部と湾曲係合凹部との雄雌嵌合で
あるから耐久的に使用し得るとともに両者の嵌合が円滑
に行える。例えば、係合部が突起と孔の雄雌嵌合であれ
ば、突起が折れたり、突起が曲がったりし易いが本発明
はこのような問題は生じない。また、係合部が突起と孔
の雄雌嵌合であれば、芯が合わない限り当然両者を嵌合
できないが、本願のように湾曲継合凸部と湾曲係合凹部
であればこのようなこともない。3. Since the engaging portion is the male and female fitting of the curved engaging convex portion and the curved engaging concave portion, it can be used durable and the both can be fitted smoothly. For example, if the engaging portion is the male and female fitting of the projection and the hole, the projection is likely to be broken or the projection is bent, but the present invention does not cause such a problem. Also, if the engaging portion is a male and female fitting of the projection and the hole, it is naturally impossible to fit both unless the cores match, but if it is a curved joining convex portion and a curved engaging concave portion like this application, Nothing.
