It has been proposed that the intersecting portions are formed into a step-like shape with one of them deeper and the other shallower, and an endless roller chain is attached to both rolling surfaces so that they can run freely (JP-A-1982-1999-1). 84.421).

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 the connecting plate during use, and in any case, it takes a lot of time and effort to assemble the roller chain. 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 unbalanced loads by deforming the roller itself. However, the reality is that it has not been put into practical use.

グに適用可能になる。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 are made of a metal material such as steel, a suitable material such as a plastic molded product, preferably a plastic molded product from the viewpoint of noise, etc., and each has a pair of engaging portions. However, when the engaging portion of one connecting member is a pair of connecting shafts, the engaging portion of the other connecting member is a pair of through holes through which the connecting shafts can rotate, and the engaging portion of the other connecting member is a pair of through holes through which the connecting shafts can rotate. When the engaging portion is a connecting shaft and a through hole, the engaging portion of the other connecting member is the connecting shaft and the through hole corresponding to the connecting shaft and the through hole of the connecting member, and the engaging portion of the other connecting member is the connecting shaft and the connecting shaft. When the joining part is a pair of through holes, the engaging part of the other connecting member is a pair of joining shafts. Furthermore, the connecting shafts protruding from these connecting members and/or connecting members must be able to be rotatably inserted into the hollow portion of the hollow roller at least.
In addition, the male coupling part and the male coupling part formed at the tip of the hollow roller are inserted into the hollow part from both ends of the hollow roller, and are butted against each other and engaged, so that at least the assembled roller chain slides. Any material that can be fixed so that it will not easily come off before it is attached to the moving table is sufficient, and if these connecting members and connecting members are made of something that has a certain degree of elasticity, such as a plastic molded product, Preferably, the male coupling part is a spherical receiver, and the male coupling part is a spherical engagement body that is coupled to the spherical receiver so as to be able to swing and rotate therein, but not to be easily detached. In this way, by forming the male coupling parts of the coupling shafts and the male coupling parts that are coupled to each other within the hollow portions 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 is increased, and the degree of freedom in connecting the loaded raceway surface, the non-load raceway surface formed on the slide table, or the endless raceway surface formed by these increases. As a result, it becomes applicable to various linear layered roller bearings.

disposed on both the left and right sides of a large number of parallel hollow rollers, the connecting shafts of which are inserted into the hollow portions of the hollow rollers from both sides of the hollow rollers, passing through the through holes of the connecting members and/or the connecting members adjacent to each other; A male coupling part and a male coupling part formed at the tips are butted against each other in this hollow part, and are engaged.
This constitutes an endless roller chain in which a large number of hollow rollers are each rotatably connected.

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

上する。[Function] According to the roller bearing for linear sliding 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 their connecting axes are inserted into the through holes from both sides of the hollow rollers. The ends of the connecting shafts can be connected by simply inserting them into the hollow portion of a hollow roller and abutting each other within the hollow portion of the hollow roller, thereby significantly improving the workability of assembling the roller chain.
