号公報）。[Prior Art] Conventionally, as this type of linear sliding roller bearing, for example, a pair of rolling surfaces are formed in a cross-shaped manner on a bearing block that is attached to a sliding table.
It has been proposed that the intersection of these raceway surfaces be formed into a step-like shape with one of them deep and the other shallow, and an endless roller chain installed on both raceways so that they can run freely ( JP-A-60-84421

とで形成されている。 However, the roller chain used in such conventional roller bearings usually consists of a large number of hollow rollers and a roller shaft that rotatably penetrates the hollow part of each of these hollow rollers and protrudes from both ends thereof. , a flat connecting plate (retainer) that is rotatably installed between the roller shafts of a large number of parallel hollow rollers that pass through the hollow parts of the adjacent hollow rollers, with their ends overlapping each other.
It is formed by.

れる。 For this reason, in this conventional roller chain, for example, a roller shaft is fitted into each of two hollow rollers, and a connecting plate is rotatably attached between each end of the roller shaft that protrudes through each hollow roller. In this way, a large number of chain structures are formed consisting of two hollow rollers, two roller shafts, and two connecting plates, and the connecting plates can rotate between each end of the roller shaft of each chain structure. and are formed by being connected endlessly.

状である。 However, the task of rotatably attaching the connecting plate between adjacent roller shafts is more difficult than expected, and if a nut or the like is used in this part, the nut will protrude to the side of the hollow roller, making it difficult to rotate it smoothly. Furthermore, even if the tip of the roller shaft is installed by caulking, if the degree of caulking becomes too large, that part will come into contact with the side of the hollow roller, impeding smooth rotation, and may cause damage to the caulking. If the degree is too small, the roller shaft may come off from the connecting plate during use, and in any case, it takes a lot of time and effort to assemble the roller chain, and roller bearings for linear sliding using this chain are not suitable for sliding. It has excellent features such as easy assembly of the roller to the moving table, no roller skew during use, and the ability to respond to uneven loads by deforming the roller itself. However, the reality is that it has not been put into practical use.

になる。 In the present invention, the connection member and the connection member that make up the connection chain refer to a relationship in which when one of the pair of members that make up the connection chain is used as the connection member, the other becomes the connection member. These connecting members and connecting members may be made of metal materials such as steel, appropriate materials such as plastic molded products, or
From the viewpoint of noise, etc., it is preferably made of a plastic molded product, and each has a pair of engaging parts, but if the engaging parts of one connecting member are a pair of connecting shafts, the connecting members of the other connecting member have a pair of engaging parts. The engaging portion is a pair of through holes through which the coupling shaft rotatably passes,
When the engaging portion of one connecting member is a connecting shaft and a through hole, the engaging portion of the other connecting member is a through hole and a connecting shaft corresponding to the connecting shaft and through hole of the connecting member, and
When the engaging portions of one connecting member are a pair of through holes, the engaging portions of the other connecting member are a pair of connecting shafts. Furthermore, the coupling shafts protruding from these connecting members and/or connecting members must be able to be rotatably fitted into at least the hollow portion of the hollow roller, and the female coupling shaft formed at the tip thereof must be rotatably inserted into the hollow portion of the hollow roller. As for the part and the male coupling part, they are inserted into the hollow part from both ends of the hollow roller, and are butted and engaged with each other, at least until the assembled roller chain is attached to the sliding base. Any material may be used as long as it can be firmly fixed so that it does not come off easily, and if these connecting members and connecting members are made of plastic molded products or other materials that have a certain degree of elasticity, preferably the female joint portion is a spherical receiving portion. The male coupling part is a spherical engaging body which is coupled into the spherical receiving part so as to be able to swing and rotate and not to be easily detached. In this way, by forming the female coupling part and the male coupling part of the coupling shaft that are coupled to each other in the hollow part of the hollow rollers so as to be able to swing and rotate, a large number of parallel hollow rollers and these hollow rollers can be connected. The degree of freedom between the rollers and the connecting chain that connects them increases, and the degree of freedom in connecting the loaded raceway surface, the unloaded raceway surface formed on the slide table, or the endless raceway surface formed by these increases. As a result, it can be applied to various linear sliding roller bearings.

連結された無端のローラチエーンが構成される。 The connecting members and connecting members constituting the connecting chain are arranged on both left and right sides of a large number of parallel hollow rollers, and their connecting shafts penetrate through holes in adjacent connecting members and/or connecting members, respectively. The hollow rollers are inserted into the hollow portions from both sides, and are brought into contact with each other within the hollow portions, so that the female coupling portion and the male coupling portion formed at the tips are engaged, thereby causing each of the numerous hollow rollers to rotate. A possibly connected endless roller chain is constructed.

It is sufficient to attach a retainer to prevent the roller chain from falling off.

業の作業性が著しく向上する。[Function] According to the linear sliding roller bearing of the present invention, the connecting chain forming the roller chain has a pair of connecting shafts, a connecting shaft and an engaging portion consisting of a through hole or a pair of through holes. When assembling this roller chain, the connecting members and connecting members are arranged on both the left and right sides of a large number of parallel hollow rollers, and the connecting shafts are inserted into the through holes from both sides of the hollow rollers. It is sufficient to pass through the shafts and fit them into the hollow portions of the hollow rollers, and to abut each other within the hollow portions of the hollow rollers to connect the ends of the connecting shafts, thereby significantly improving the workability of the roller chain assembly work.
