and 1b are machined separately, so the mating surfaces 8a and 8b to be joined during assembly must be machined separately. It is difficult to process well due to exposure, and even if it were possible, it would require extremely high processing costs. Furthermore, since the rolling surfaces 3a and 3b constituting the inward 7-shaped groove 3 on which the roller 7 rolls are processed with the mating surfaces 8a and 8b temporarily assembled, the mating surfaces 8a and Unless 8b is finished with high precision, the rolling surfaces 3a and 3b cannot be machined with high precision, and the turning movement between the inner and outer rings 1 and 4 performed via the rollers 7 cannot be made smooth and accurate.

Since there is a gap between the bolt 9a and the bolt hole 10 through which the bolt 9a passes, even a slight loosening between the bolt 9a and the nut 9b will cause a misalignment between the pair of outer ring members 1a and 1b, causing the outer periphery to Face and introvert V? Misalignment occurs between the raceway surfaces 3a and 3b constituting the groove 3 and between the raceway surfaces 3a and 3b, and as a result, there is a problem that it is difficult to maintain high precision and smooth turning movement is hindered.

The bolts 9a and nuts 9b used for attachment are removed, and the inner circumferential surface and rolling surfaces 6a and 6b forming the outward 7-shaped groove 6 are ground as an integral part with one of the outer ring members 1a or 1b. A roller 7 and a spacer retainer (not shown) are installed between the inner ring 4 and the inner ring 4.
This requires many manufacturing steps such as fitting the outer ring members 1a and 1a and connecting the pair of outer ring members 1a and 1b with bolts 9a and nuts 9b. When grinding the side surfaces and raceway surfaces 8a and 8b, the pair of outer ring members 1a and 1b become misaligned with each other, making it difficult to perform highly accurate grinding.

る。[Means for Solving the Problems 1] The present invention has been developed in view of this point of view, and instead of dividing the outer ring in the circumferential direction, it forms a dividing surface in the radial direction on the outer ring. Not only can the rolling surface of the roller that makes up the inward 7-shaped groove be machined with high precision, but also errors may occur between the outer circumferential surface and the inward 7-shaped groove and between the rolling surfaces that make up this inward V-shaped groove during use. The present invention provides a cross roller bearing that does not have such a problem, and also provides a method for manufacturing such a loss roller bearing.

グでおる。That is, the '1st invention forms an inward seven-shaped groove that opens inward along the circumferential direction of the inner circumferential surface of the outer ring, and also forms an inward seven-shaped groove that opens inward along the circumferential direction of the outer circumferential surface of the inner ring. In a cross roller bearing in which an outward 7-shaped groove is formed facing the 7-shaped groove, and a roller is interposed between the inward 7-shaped groove and the outward 7-shaped groove, the outer ring is broken at an appropriate position. The cross roller bearing has a radial dividing surface and is expandable on the dividing surface.

スローラーベアリングの製造法である。Moreover, the second invention forms an inward 7-shaped groove that opens inward along the circumferential direction of the inner circumferential surface of the outer ring, and
A cross roller formed by forming an outward V-shaped groove opposite to the inward V-shaped groove along the circumferential direction of the outer peripheral surface of the inner ring, and interposing a roller between the inward V-shaped groove and the outward V-shaped groove. When manufacturing bearings, a notch facing in the radial direction is carved into the outer ring, and an external force is applied to this notch to cause it to break, thereby forming a radial dividing surface.The outer ring is expanded at this dividing surface. This is a method of manufacturing cross roller bearings that incorporates rollers between the outer and inner rings.

性も確保される。In the present invention, the outer ring is divided into υ1 by fracture in the radial direction.
To form a surface, first a notch is carved in the outer ring in the radial direction of the outer ring, but the depth direction of this notch only needs to roughly match the radial direction of the outer ring, and the dividing surface is formed. It may be formed over the entire parting line or only on a part of the parting line, but it is preferably formed on the inner surface of the outer ring where stress concentration occurs when it is broken by means such as pressing. It is better to do so. By making the split surface a fracture surface formed by fracture in this way, after the outer ring is expanded at the split surface and a roller etc. is installed between these inner and outer rings, these split surfaces can be completely aligned. Even if there is a slight gap between the split surfaces when not in use, by incorporating it into a mechanical device such as a swivel when in use, the split surfaces will match perfectly and the outer ring will be perfectly round. Sex is also ensured.

In addition, since the dividing surfaces are fractured surfaces formed by fracture, they can be perfectly aligned, and even if there is a slight gap between the dividing surfaces in the radial direction, this outer ring can be incorporated into a mechanical device such as a rotating part. At the same time, its roundness is ensured.

。Further, according to the method for manufacturing a cross roller bearing of the present invention, it becomes easy to grind the raceway surface of the roller that constitutes the inward 7-shaped groove of the outer ring, and it is also possible to process this raceway surface with high precision. Furthermore, since the outer ring is manufactured without dividing into two parts, the manufacturing process is extremely simplified.
