The present invention provides a floating connector that allows relative deviation in the direction and position of the central axes of reciprocating motion between the driving side and the driven side, and also exhibits a buffering effect at the end of the reciprocating motion.

。In a reciprocating mechanical device, as illustrated in FIG. 1, a connector 5 is provided between a reciprocating driving part 1 and a driven part 2 to connect these two parts, and a shock has a shock absorbing function at the end of the reciprocating movement. Absorber 6 is used.

よる温度上昇等のトラブルの発生を見ることがある。Threaded joints and flange joints are known as simple mechanisms used in the connector 5, but in devices using these coupling means, the direction of reciprocating motion between the driving side and the driven side and the central axis are fixed. If the positions do not match each other, smooth movement is not allowed, and it is extremely difficult to align the driving and driven sides.
With reciprocating operation, problems such as chatter, galling, uneven wear, and temperature rise due to friction may occur.

れることができない。As a measure to solve the above-mentioned problem at the joint between the driving side and the driven side, we use both an Oldham coupling and a pole joint, the former absorbs the deviation of the center axis, and the latter allows the center axes to move toward each other. It is known that this method absorbs the inclination of the joint, but this method requires a complicated structure of the joint, resulting in an increase in cost and weight.

The joint member forms a floating connector that can relatively change the direction and position of the central axis due to the flexibility of the rubber-like elastic material, and the center of reciprocating motion between the driving side and the driven side. The rubber-like In order to prevent the joint member made of elastic material from being damaged due to excessive stretching or contraction, a joint member is provided between one joint member and the other joint member that is relatively movable in the axial direction and that is aligned with the axis. A restraining means is also provided so that the direction can be relatively changed.

。In the embodiment shown in FIGS. 2 to 4, one joint member 11 connected to the driving part 1 and the other joint member 12 connected to the driven part 2 are made of rubber-like elastic material. are connected by a joining member 14 having a substantially cylindrical shape, and one joint member 1 is connected to the other joint member 12 side.
A cylindrical member 16 extending toward one side and having a bottom plate 17 with a through hole 18 attached to the inner end thereof is coupled, and a disk-shaped head 22 is attached to one joint member 11 side. A stopper piece 21 that is loosely inserted into the through hole 18 is connected thereto.

、装置の往復運動がスムースに行なわれる。In a device in which a driving side and a driven side are joined using a floating connector having the above-mentioned configuration, deviation in direction and position of the central axis of the driving side and the central axis of the driven side may occur due to the joining member 14. Due to its flexibility, the device can be smoothly reciprocated.

ストロークの終末においては接合部材１４が、第３図に
示される如く、両接手部材１１．１２により圧せられて
収縮するが、或いは第４図に示される如く、両接手部材
１１．１２により引張られ、伸長して緩衝作用をなす。At the end of the stroke, the joining member 14 is either compressed and contracted by both joint members 11.12, as shown in FIG. 3, or pulled under tension by both joint members 11.12, as shown in FIG. It expands and acts as a buffer.

接合部材１４が収縮する際には、第３図に示される如く
円筒状部材１６の先端と一方の接手部材１１の端面とが

接して接合部材１４の過度の伸長を阻止する。When the joining member 14 contracts, as shown in FIG. When the joining member 14 is extended, the disc-shaped head 22 of the restraining piece 21 comes into contact with the bottom plate 17 of the cylindrical member 16, as shown in FIG. 4, to prevent the joining member 14 from extending excessively.

における干渉は生じない。Since the stopper piece 21 and the through hole 18 of the bottom plate 17 are maintained in a loosely engaged state, deviation in position and direction between the center axis of one joint member 11 and the center axis of the other joint member 12 is prevented. Even if there is deviation, no interference occurs at the engaging portions of both members.

なされ、装置は長期の使用に耐える。The driving side joint member 11 and the driven side joint member 12 are
They are joined by a flexible joining member 14, and the protection means against excessive stretching and compression of the joining member 14 includes:
Since they are formed so that they can fit loosely into each other and absorb relative positional deviations and mutual inclinations of the axes, discrepancies in the position and direction of the central axes between the driving side and the driven side can be absorbed very easily. Therefore, in mechanical equipment equipped with this floating connector, the chatter phenomenon caused by deviation and inclination of the central axis seen in conventional connectors,
There is no galling phenomenon, the reciprocating operation is extremely smooth, and the device can withstand long-term use.

作用効果がもたらせる。Note that the shape of the joining member 14 is not limited to the cylindrical shape illustrated in the embodiment, but may be a hollow truncated cone shape with different diameters at both ends, or a shape in which the diameter of the center part is the same as the diameter of both ends. On the other hand, the same effect can be obtained by using an appropriate shape such as a larger barrel shape or a drum shape where the diameter of the center part is smaller than the diameter of both ends.
