の着脱が可能となる。 The structure of the universal joint is disclosed in Japanese Utility Model Application No. 50-83444, Japanese Utility Model Application Publication No. 55-89816, and Japanese Utility Model Application Publication No. 46-24729.
Those described in No. 1, etc. are known. Jitsukai Showa 50
In the universal joint described in the -83444 publication, a pin on the coupling side is engaged with an engagement groove of a connecting portion provided on the driving shaft side, and this engagement groove is open to the driven shaft side. Further, in the universal joint described in Japanese Utility Model Application Publication No. 55-89816, a rectangular inner shaft and an outer shaft are engaged with each other so as to be slidable in the axial direction. Therefore, in these universal joints, by separating and bringing both shafts closer together in the axial direction, it becomes possible to attach and detach the shafts at the joint portion.

なる。 In addition, since it is necessary to connect both shafts while visually confirming the connection state, there is a problem in that the joining operation is time-consuming. For example, in the 1970s
In the universal joint described in Publication No. 83444, it is necessary to rotate the driving shaft or the driven shaft so that the angles of both shafts match while checking the state of the engagement groove of the pin and the connecting portion, and then connect both shafts. Also, in 1987-
Even in the universal joint described in Publication No. 89816, it is necessary to connect both shafts with the angles of the inner and outer shafts perfectly matching at the connecting shaft part, and once the inner and outer shafts are uncoupled, it is necessary to connect them again. It becomes very difficult to combine.

Similarly, a spherical projection R 2 is press-fitted onto the drive shaft 5 side. Springs 10, 10 are interposed between the spherical protrusions R 1 and R 2 in a compressed state. Therefore, the springs 10, 10 urge the main body 1 toward the driven shaft 7, the joint side pin 9 presses the driven shaft 7 in the through groove 8, and the main body 1 and the driven shaft 7 are biased together. This is what we are doing.

て、挿入が容易となる。 In the state shown in Fig. 2, if the driven shaft 7 is moved away from the drive shaft 5, the through groove 8 of the driven shaft 7 will come off the joint side pin 9, and the driving of both shafts 5 and 7 will be cut off. Ru. Next, when recombining the driven shaft 7, move the driven shaft 7 to the drive shaft 5 and insert it into the through hole 2 of the main body 1, the joint side pin 9 will be inserted into the through groove 8, and the second The result is the combined state shown in the figure. In this case, the end surface of the main body 1 on the driven shaft 7 side has a spherical projection R 1
Since the inner diameter of the hole is larger than that of the driven shaft 7, the shaft can be easily inserted even if the axes of the shafts 5 and 7 are misaligned. When the driven shaft 7 is inserted with its axis misaligned, the end of the driven shaft 7 rides on the surface of the spherical protrusion R1 , and a force is applied to the main body 1 in a direction perpendicular to the axial direction of the joint side pin 9. However, the main body 1 has long grooves 3, 3
is bored, the main body 1 rotates slightly in a direction perpendicular to the axial direction of the joint side pin 9, and both shafts 5, 7
positional deviation is absorbed and positioning is performed automatically. Also, before the driven shaft 7 is inserted, the main body 1
is pushed toward the driven shaft 7 side by the spring 10 and positioned by the shaft side pin 6, so the main body 1
does not tilt downward due to its own weight, and the main body 1 and the driven shaft 7 are maintained parallel to each other. Therefore, insertion becomes easy.

になる。 Further, when the driven shaft 7 is inserted, the angles of the through groove 8 and the joint side pin 9 do not necessarily match, and for example, they may intersect as shown in FIG. 3. In this case, first, the tip of the driven shaft 7 comes into contact with the joint-side pin 9, and the main body 1 is pushed down against the spring 10, resulting in the state shown in FIG. 4.
ここで、長溝３の軸方向の長さl1の長さは、貫

３図のように貫通溝８が継手側ピン９に交差した
状態で従動軸７が挿入されても、本体１が充分に

動できるようになつている。 Here, the axial length l 1 of the long groove 3 is longer than the axial length l 2 of the through groove 8, and the through groove 8 is connected to the joint side pin 9 as shown in FIG. Even if the driven shafts 7 are inserted in a crossed state, the main body 1 can move sufficiently in the axial direction so that the driven shafts 7 can move to a predetermined position.

る。 When the drive shaft 5 is rotated in this state, the right angles of the through groove 8 and the joint side pin 9 are aligned, and the joint side pin 9 falls into the through groove 8 due to the biasing force of the spring 10, and both shafts 5 and 7 are rotated. The join will be done automatically and
The combined state shown in FIG. 2 is obtained. That is, even if the joint side pin 9 and the through groove 8 intersect, if the driven shaft 7 is inserted as is and the drive shaft 5 is rotated, both shafts 5 and 7 can be automatically connected. There is no need to visually check the correspondence between the joint side pin 9 and the through groove 8. Note that the rotation of the drive shaft 5 is automatically performed by a drive source connected to the drive shaft 5, and even in the worst case, the drive shaft 5 will be connected to the driven shaft 7 after half a rotation from the initial state.

As explained above, according to the present invention, the inner diameter of the other shaft side of the universal joint main body is increased toward the end side, and the inner diameter of the end side is made larger than the outer diameter of the end of the other shaft. Because of this, even if the axis is misaligned when the shaft is inserted, positioning will be performed automatically. In addition, even if the angles of the through groove on the other shaft and the pin on the joint side do not match when inserting the shaft, if the shaft is rotated, the pin on the joint side will automatically fall into the through groove due to the biasing force of the spring. Both shafts can be automatically connected without visually checking the correspondence between the side pins and the through grooves. Therefore, according to the present invention, precise positioning is not required, and the joining operation becomes easy. In addition, since the structure is simple, the parts related to the shaft and the universal joint are easy to manufacture, and production costs can be reduced.
