CONSTITUTION: As for a cross roller bearing which is constituted so that the V-shaped rolling grooves 2 and 4 which are set at right angle and installed on the outer peripheral surface of an inner ring 1 and the inner peripheral surface of an outer ring 3 are opposed, and the rollers 5 and 6 whose axis centers are varied in the right direction alternately are accommodated in the rolling groove, the annular guides 71-74 which are made of the self lubricating solid material and project into the rolling groove are installed at both the end positions of the inclined surfaces 2a, 2b, 4a and 4b which form the rolling grooves 2 and 4. The outer peripheral surfaces of the rollers 5 and 6 are rolled on the inclined surface, and both the end surfaces are contact-held on the annular guide at both the side parts. Accordingly, the slip friction on the end surface of the roller reduces, and also the holding of the roller is stabilized.

The rectangular V-shaped rolling groove 4 formed by
A large number of rollers 5 and 6 whose axial centers are alternately changed in the direction perpendicular to each other are housed in the facing gap via a separator (not shown). Therefore, the roller 5 inserted in one axial direction rolls by contacting the outer peripheral surfaces with the facing inclined surfaces 2a and 4b of the rolling grooves 2 and 4, while rolling on both end surfaces of the other inclined surface 2b. 4a, the end face and the inclined face come into contact with each other during rotation to cause sliding friction, and the roller 6 inserted at the other axis also similarly has both end faces contacting the inclined faces 2a and 4b. It causes sliding friction.

案されている。As described above, between the rolling groove surfaces of the inner and outer races and the roller end surface, a circular friction torque due to the rotation of the roller and a friction torque along the rolling groove due to the rotation of the bearing are generated. In particular, at the outer ring side end surface, the roller is pressed against the inclined surface by the centrifugal force, and a large friction torque is generated, which causes abnormal wear and seizure, and the bearing life is shortened. In consideration of this point, at least the outer end surface of the roller, which comes into contact with the outer ring, is formed as a convex curved surface of medium height, and the convex curved surface is opposed to the rolling groove of the outer ring to reduce the abrasion resistance with the inclined surface. As disclosed in Japanese Patent No. 63-225729, it is proposed that both end surfaces of a roller are fixed or covered with members made of different materials having low friction to reduce sliding friction on the end surfaces.

ローラーの保持を安定させることを目的とする。However, by providing a convex curved surface on the roller end surface, it is possible to reduce the sliding friction between the roller end surface and the rolling groove, but since the sliding contact occurs at the center of the convex curved surface, Since the frictional resistance of the part is large and the contact point slides along the rolling groove, it is not possible to prevent seizure, but also the roller end surface is supported only by the central point contact, which makes the roller posture unstable. Therefore, there is a drawback that the roller is inclined during rolling and abnormal wear is increased. Further, it is troublesome to provide a different material on the roller surface, and the cost increases because all rollers are processed. In view of the above points, the present invention reduces sliding friction without performing processing on the roller end surface,
The purpose is to stabilize the holding of the roller.

The outer peripheral surface of each roller is brought into contact with and rolls on the inclined surface between the annular guides, and the end surfaces on both sides are held in contact with the protruding surface of the annular guide without being brought into contact with the rolling grooves.

Therefore, it is held with a sufficient gap so as not to come into contact with the inclined surface, and the contact portion with the annular guide makes sliding contact with low friction due to the self-lubricating solid material. Further, since both side portions of the roller end surface are supported by the annular guide, the posture of the roller is stably maintained and the roller does not fall.

ある。EXAMPLE An example shown in FIG. 1 will be described below.
Reference numeral 1 is an inner ring, and 2 is a right-angled V-shaped rolling groove provided on an outer peripheral surface of the inner ring 1, which is formed by orthogonal inclined surfaces 2a and 2b.
Reference numeral 3 denotes an outer ring that is divided into two in the thickness direction, and has inclined surfaces 4a and 4b that are respectively orthogonal to the inner peripheral surface to form a V-shaped rolling groove 4 that is orthogonal. Numerals 5 and 6 are rollers housed in the facing gaps of the rolling grooves 2 and 4 and fitted and arranged with separators (not shown) alternately having their axes centered orthogonally to each other, and their outer peripheral surfaces are respectively inclined surfaces 2a and 4b. And 2b and 4a are contact-rolled. 71, 72, 73, 74 are inclined surfaces 2a, 2b, 4 so as to correspond to the corners of the rolling grooves 2, 4, respectively.
An annular guide made of a self-lubricating solid material that is provided at both end positions of a and 4b and is projected into the rolling groove along the rolling groove,
Retaining grooves 81 provided on both inclined surfaces,
Inserted in 82, 83, 84, the tip end portion protruding into the rolling groove is formed at a right angle with a surface parallel to the inclined surface. Reference numeral 9 denotes a gap between the roller end surface and the inclined surface due to the protrusion of the annular guide.

And contacting and holding the annular guides 71, 72, 73, 74 at the contact portions S on both sides of the peripheral edge of the end face.

部両側の小さい接触部分だけが滑り摩擦で接触する。Therefore, when the inner ring 1 and the outer ring 2 rotate relative to each other, the outer peripheral surface of the roller 5 comes into contact with the inclined surfaces 2a and 4b and rolls along the rolling grooves 2 and 4, and the outer end surface of the roller 5 moves. Only the contact portions S on both sides of the peripheral edge contact the self-lubricating annular guides 72 and 73 to cause sliding friction, and the inner end face is also formed only by the contact portions S on both sides of the peripheral edge.
And 74 to move in the rolling groove by sliding friction. Similarly, the outer peripheral surface of the roller 6 rolls along the inclined surfaces 2b and 4a, and both end surfaces are held in contact with the annular guides 71 and 74 only at the contact portions on both sides of the peripheral edge and contact the inclined surfaces 2a and 4b. Instead, the small contact portions on both sides of the peripheral edge are brought into sliding friction contact with the self-lubricating annular guides 71, 73 and 72, 74 which are protruded into the rolling groove through the gap 9.

It can also be installed circumferentially divided for insertion into the rolling groove. As the self-lubricating solid material forming the annular guide, known plastic materials such as polytetrafluoroethylene resin filled with a fibrous reinforcing agent, polyether ether ketone resin, polyphenylene sulfide resin, polyether sulfone resin, and polyimide resin.

向上と寿命の長期化が得られる。As described above, according to the cross roller bearing of the present invention, the self-lubricating solid that projects into the rolling groove at both ends of the inclined surface forming the rolling groove and contacts both sides of the peripheral edge of the end surface of the roller. Since an annular guide made of material is provided, the roller end surface is held through a gap without contacting the rolling groove, and a small range of contact surfaces on both sides of the end surface contact the self-lubricating annular guide. Since it is held, the friction torque due to sliding friction is small, and accidents such as seizure of the roller end surface do not occur, and both ends of the roller end surface are supported by annular guides, so the roller shaft center is held securely. , Rollers can be prevented from falling, abnormal wear due to one-sided contact can be eliminated, rolling can be performed smoothly, and the bearing characteristics can be improved and the service life can be extended.

If the contact surface of the annular guide with the roller is formed as a convex curved surface, sliding friction can be further reduced.
