[Detailed description of the invention] The present invention is a casing for an infinite linear motion roller bearing in which a casing that straddles a linear track rail can perform infinite linear motion via a large number of rollers that circulate infinitely within the casing. This relates to a side plate that is attached to the front and rear of the side plate, and the side plate is divided into an upper member and a lower member at the direction change path in order to facilitate the formation of a direction change path consisting of a complex three-dimensional curved surface bored inside the side plate. The two members are molded separately, and the finished members are accurately and reliably joined, and the direction change path of the side plate is connected to a load track formed vertically parallel to the direction of movement of the casing in the endless circulation path. It is an object of the present invention to provide a side plate in which a turning path is formed with a complicated three-dimensional curved surface that can be connected to both ends of a straight path with a return path at an accurate position.

Conventional infinite linear roller bearings have a large number of rollers that are held in a link chain cage and connected together, but in order to increase the load capacity of the roller bearing, the number of rollers has been increased. A system has been devised in which adjacent cylindrical rollers having approximately square axial cross-sections with approximately equal diameters and heights are directly adjacent to each other and installed in an endless circulation path without having the cage. Ta. As shown in FIG. 8, the endless circulation path is a linear load track 3 formed between the track rail 2 and the casing 1 in the direction of movement of the casing 1.
, a linear return path 4 formed parallel to the load track 3, and a semicircular arc-shaped direction change path 6 provided at both ends of the straight paths 3, 4 so that the roller 5 can smoothly change direction. However, the respective axes of the straight paths 3, 4 and the two-way switching paths 6, 6, which have a substantially square cross section, are perpendicular to the facing surfaces 7, 8 of the track rail 2 and the casing 1. are on the same plane P, and both the formation of the direction change path 6 and the side plates on which the direction change path 6 is formed were easy to manufacture.

In the present invention, as shown in FIG. 7, the return path 4 protruding from the casing 1 is connected to the load track 3 formed between the facing surface 7 of the track rail 2 and the facing surface 8 of the casing 1. The facing surfaces 7 and 8
The width B of the casing 1 can be made smaller by providing it at a higher position than the perpendicular direction on the load track 3, but as a result, the endless circulation path of the rollers 5 is a straight path. Load track 3
A direction changing path 6 connecting both ends of the return path 4 and allowing the roller 5 to roll smoothly while changing direction between the straight paths 3 and 4 is formed by a semicircular arc-shaped surface when projected on a horizontal plane. As shown in FIG. It has become extremely difficult to manufacture the side plates 9, 9 in which the turning path 6 is bored.

The fixing bolts 10 and other fixing devices for fixing the side plate 9 to the front and rear end faces of the casing 1 are installed at positions that are suitable for infinite linear motion roller bearings in which the rollers 5 rolling on the endless circulation path can smoothly circulate endlessly. It should not be located in a position that would interfere with the basic functions of the side plate 9, and should be located in an appropriate empty space that can maximize the adhesion force of the side plate 9 to the casing 1, and that is located away from the three-dimensional arc-shaped turning path 6. It must be. Once the problem of selecting the position of the fixing bolt 10 on the side plate 9 is solved, the direction change path 6 and the load track 3, and the direction change path 6 and the return path 4 are then solved.
In particular, the rollers 5, which have been rolling under load on the load track 3, can be smoothly transferred to the direction change path 6, and smoothly sent to the return path 4. It is necessary to accurately match the relative positions of both ends of the direction change path 6 of the side plate 9 with the load track 3 and the relative position with the return path 4.

The present invention has the configuration described in the claims for utility model registration, whereby both the load track and the return track, which are straight tracks provided in parallel at different heights in an infinite linear motion roller bearing, are parallel to each other. The side plate, which connects both ends of the path and forms a three-dimensional arc-shaped direction change path that allows the rollers to change direction smoothly, is divided into two by an arcuate surface in the direction of movement of the casing along the axis of the direction change path. It is formed by an upper member and a lower member, and the upper member and the lower member are connected by a side plate assembly bolt having an axis that intersects the center line of curvature of the arcuate surface. It is now possible to accurately form a direction change path with a complex shape, assemble it in the correct position, and assemble the assembled side plate more accurately than before, and to make the rolling of the rollers rolling in the direction change path smoother. In addition, it becomes possible to maintain the end face positions of the direction change path, load track, and return hole more accurately, making it possible to easily and accurately manufacture the side plates, reducing production costs, shortening assembly time, This is an idea that has various effects that improve assembly accuracy and also make it possible to realize an infinite linear motion roller bearing with less frictional resistance.
