Reference numerals 1 and 2 are yokes, 3 is a cross body, and has four axes (hereinafter referred to as cross axes) 4. Reference numeral 5 denotes a bearing which is interposed between the cross shaft 4 and the walls of the bearing holes 6 of the yokes 1 and 2, and which rotatably holds the cross shaft 4, and 7 prevents the bearing 5 from coming off the bearing hole 6. Snap ring 8 is a grease nipple.

合もある。When assembling this, the two cross shafts 4 of the cross body 3 are inserted into the two bearing holes 6 of the yoke 1,
The other two cross shafts 4 are connected to the two bearing holes 6 of the yoke 2.
Then, the bearings 5 are inserted from the outside of the bearing holes 6 between the cross shaft 4 and the bearing hole walls, respectively. Then, the snap ring 7 is fitted to fix the bearing 5 to the yokes 1 and 2. Since the bearing 5 is fixed by the snap ring 7 as described above, this kind of universal joint may be commonly referred to as a snap ring type.

という問題があった。However, in this snap ring type universal joint, the bearing 5 is attached to the cross shaft 4
Since it is inserted later between the bearing hole wall and the bearing hole wall, it is necessary to make the inner diameter of the bearing hole 6 slightly larger than the outer diameter of the bearing 5 to provide a gap to facilitate the entry.
However, when the clearance is provided, the fixing force is weak although it is fixed by the snap ring 7, so that there is a so-called bearing creep phenomenon in which the bearing 5 is rotated along with the rotation of the cross shaft 4 during the operation load. As a result, the bearing hole is worn and rattles, or seizure occurs. If an attempt is made to increase the tightening force by eliminating the gap, an excessive force may be applied to insert the bearing 5 and the yoke may be deformed. Even if the bearing 5 can be mounted somehow, it is extremely difficult to dismantle the bearing whose life has expired for a new bearing.
Especially when it is used for steel making machines, the bearing hole with play is corroded and rusted, so it is very difficult to disassemble. There was a problem that it had to be processed.

と共に、解体作業もきわめて容易になる。In order to eliminate the above problems of the snap ring type, there is a so-called cap type universal joint as shown in FIG. In this structure, a semicircle of the bearing hole 12 is formed in the yoke body 11, and the other semicircle of the bearing hole 12 is formed in the removable cap portion 13. Therefore, when assembling the universal joint, first, the cross shaft 4 and the bearing 5
The bearings 5 are respectively mounted, the bearings 5 are positioned in the bearing holes of the yoke body 11, the caps 13 are covered, and then the bolts 14 are tightened. Here, if the bearing hole 12 is provided with a tightening allowance so that the bearing hole diameter is smaller than the outer diameter of the bearing 5 by the tightening allowance, the bolt 14 can be tightened to tightly tighten the bearing 5 and the snap ring. Problems such as wear and seizure of the type are solved, and dismantling work becomes extremely easy.

Most of the failures in this type of cap type universal joint are due to the breakage of this bolt. There is also a problem that the structure is complicated and the cost is high.

Since the bearing hole has a gap between the bearing hole wall and the bearing when the slit is opened, it is extremely easy to insert and remove the bearing during assembly and disassembly. On the other hand, since there is a tightening margin for tightening the bearing, it can be firmly tightened when the slit is closed, and therefore the bearing does not rotate with the rotation of the cross shaft, and the bearing does not rotate. It is possible to prevent wear and seizure of the holes. Further, since the force applied to the bolt that closes the slit is a tensile stress that matches the axial direction of the bolt, the bolt is not damaged.

The hole diameter when the slit 23 is closed is, for example, 0.1 to 0.2 mm with respect to the outer diameter of the bearing. Further, when the slit 23 is opened and the gap α is set to 2 to 3 mm, for example, the hole diameter is such that an appropriate gap is generated with respect to the outer diameter of the bearing.

でベアリング５の離脱防止を行う。When assembling the universal joint, as in the case of FIG. 3, the two cross shafts 4 of the cross body 3 are inserted into the two bearing holes 22 of the one yoke 21, and the other two cross shafts 4 are inserted. Two bearing holes on the other yoke 22
After inserting into the bearing 22, the bearings 5 are respectively inserted between the cross shaft 4 and the bearing hole wall from the outside of the bearing hole 22. In this case, since the slit 23 is open and there is a gap between the slit 23 and the bearing hole wall, the insertion of the bearing 5 is extremely easy. Therefore, if the bolt 24 is passed through the bolt hole 25 and tightened so as to close the slit 23 together with the nut 26, the bearing 5 is tightly tightened by the tightening margin. Finally, for reinforcement, the snap ring 7 is fitted to prevent the bearing 5 from coming off.

If the and are relaxed, the slit 23 opens due to the elasticity of the yoke itself, and a gap is created between the bearing hole wall and the bearing 5, so that the bearing 5 can be easily removed.

Therefore, the bearing rotates as the cross shaft rotates. So-called bearing creep phenomenon does not occur, and wear and seizure of the bearing hole can be prevented. In addition, since the force applied to the bolt during operation is tensile stress in the axial direction of the bolt, the bolt can sufficiently withstand the force in this direction, eliminating damage to the bolt, which was a major drawback of the prior art. The property is greatly improved.
