な品質の糸が加工出来ないという致命的な欠点と
なる。 Currently, in machines that use many line shafts, such as textile machines such as false twisters, roving frames, and spinning machines, the long shaft of 10 to 20 m is divided into several equal parts, each of which is connected via a joint. , a type in which the shaft is supported by a shaft support bearing in the middle is adopted. 1 to 3 are explanatory diagrams of a conventional device showing an example of a false twisting machine, in which 1 is a line shaft, 2 is a well-known shaft support bearing, 3 is a joint for connecting equally divided shafts, and 4
5 is the gearbox installed at the end of the machine, 5 is the main body frame, and 6 and 7 are take-up frames. Line shaft 1 has 6 shafts on main frame 5 and 6 on take-up frames 6 and 7, totaling 12
Books are used, and each shaft has a length of 11 to 12 meters. Therefore, these line shafts 1 are equally divided into about 8 shafts, each of which is connected via a joint 3, and is supported by a shaft support bearing 2 in the middle, so that one long line shaft is formed as a result. It is configured. However, in machines equipped with such long shafts, so-called line shafts, the line shafts bend during operation due to sliding or other causes, making it impossible to maintain the accuracy of the shafts during installation. Conventionally, gear joints, chain joints, etc. have been used as a countermeasure against this problem. However, in this conventional device, the shaft support part and the joint part are provided separately, so the space in the axial direction becomes long, and
If the axis misalignment is large, the uniform velocity of each axis is lost. Therefore, when the axial space becomes longer, the number of cones that can be set per machine is limited or the length of the entire machine becomes significantly longer, which greatly affects the price of the machine. Furthermore, if uniform velocity is lost, the number of rotations between each fiber becomes uneven, which is a fatal drawback in that yarn of uniform quality cannot be processed.
この考案は従来の装置の上記欠点に鑑み、これ
を改良除去する為に軸支持部と継手部を一つに組
み込んだ構造の軸受装置を提供するものである。 In view of the above-mentioned drawbacks of conventional devices, this invention provides a bearing device having a structure in which a shaft support portion and a joint portion are integrated into one, in order to improve and eliminate these drawbacks.

Three guide grooves 18, 18' are provided on the outer circumferential surface of the guide groove 18, 18', parallel to each other in the axial direction and facing each other. 19
1 is a joint inner member (hereinafter simply referred to as a torque tube) having a hollow portion 20 at its tip, and three engaging portions, for example, window holes 21, are bored therein. The tip of the torque tube 19 is inserted into the annular gap 17 of the joint outer ring 14, and torque is transmitted to the joint outer ring 14 or the center shaft 16 via the torque transmission ball 22 fitted into the guide grooves 18, 18' and the window hole 21. The tube 19 is made to transmit power. Torque tube 19
can move in the axial direction along the guide grooves 18, 18' of the joint outer ring 14 via the torque transmission ball 22,
Moreover, it can be bent freely at a certain angle with respect to the joint outer ring 14. A hollow portion 23 is provided at the opposite end of the torque tube 19, and is connected to a shaft 25 constituting a line shaft via a pin 24. A boot 26 is used to form a grease filling space 27, and is mounted across the outer ring 14 and the torque tube 19. In this case, boots 2
6 is designed to be smaller than the outer diameter of the joint outer ring 14, the needle bearing 12 of the joint outer ring 14

Furthermore, even if the torque tube 19 bends with respect to the joint outer ring 14, the torque transmission ball 22 moves along the guide grooves 18, 18', and the instantaneous center of rotation of the torque tube 19 moves toward the joint outer ring 14.
It is possible to maintain constant velocity by shifting the axis from the axis. Therefore, each torque tube 19
If the shaft 25 is inserted into the hollow portion 23 of the shaft 25 and connected via the pin 24, torque can be transmitted from one shaft 25 to the other shaft 25 at a constant speed.

誤差を吸収することができる。 As explained above, this invention is a bearing device that connects two shafts and supports the connecting portion thereof, and has a plurality of joints for connecting the shafts on both sides of the inner peripheral surface in the axial direction. a joint outer member having a guide groove, and a plurality of engaging portions corresponding to the guide grooves,
and two inner joint members which are inserted into both ends of the outer joint member and have a shaft connected to the other end, and which engage the guide groove of the outer joint member and the engaging portion of the inner joint member. A plurality of torque transmission balls for jointly transmitting torque have uniform velocity, and the inner joint member is connected to the outer joint member,
The outer member of the joint is rotatably inserted into a housing fixed to the frame via a bearing, and the outer member of the joint is configured to be slidable in the axial direction. Since both ends of the boot are attached to the member and the two inner joint members or the shaft connected to the inner joint members, the following effects are limited. That is, by using a constant velocity ball joint, the constant velocity of the shaft can be maintained, and the inclination of the shaft can be largely absorbed.
Furthermore, since the joint portion and the shaft support bearing portion are integrated into one body, the overall size and weight are reduced. Therefore, the number of cones per shaft increases and the cost of the entire machine decreases. Furthermore, since the shaft is inserted into the joint and fixed with a pin, handling is easy and reliable.
Furthermore, since the joint part and the shaft support bearing part can be easily separated, the line shaft can be easily assembled and disassembled.
Furthermore, the joint part can expand and contract in the axial direction, and can absorb installation errors.
