Description

[Detailed Description of the Invention] Technical Field The present invention relates to clutch devices for rotating equipment, etc. that must be maintained remotely within a cell in order to avoid radioactive contamination in the field of nuclear equipment. The present invention relates to a clutch device that detachably connects opposing shaft ends of equipment so that rotational force can be transmitted to each other.

Prior Art Rotating equipment used in a high-temperature atmosphere inside a nuclear facility may require remote maintenance or replacement due to an accident or maintenance. Work is performed to maintain and replace shafts and other equipment.

In such cases, a clutch is inserted into the joint between the shafts, but considering that the work must be done remotely, there has not been a clutch device suitable for this work in the past. Furthermore, when the rotary shafts that have been separated are reassembled and connected, a phase shift occurs, and it is difficult to correct the phase shift when it is necessary to synchronize the rotary shafts. For example, in the past, as shown in FIG.
Spur gears 23 and 24 were attached to the shaft ends of a and 22a, and these were meshed and connected. 25 in the diagram
These are support bearings for the rotating shafts 21a and 22a, and by attaching and detaching these, the two devices can be connected or separated.

However, in the case of this conventional configuration, not only does it have the above-mentioned drawbacks, but also the rotating shafts 21a, 22a
A large force due to the weight of the support bearing 25 is applied to the shaft end of the shaft, and the parts are also large and space is taken up.

OBJECTS OF THE INVENTION It is an object of the present invention to improve the above-mentioned conventional drawbacks, and to provide a clutch device that can easily and reliably connect the shafts of a rotating device, and can easily correct phase shifts.

Summary of the invention In order to achieve the above object, the present invention is based on the invention, in which the shaft ends of two adjacent devices face each other on the same line, and in the clutch device that connects these shaft ends, each shaft end is pivotally supported. Among a pair of teeth clutches, one teeth clutch is fixed to the shaft end, while the other teeth clutch is spline-coupled to the shaft end, and the outside of each teeth clutch has opposing end surfaces in contact with each other. One frame is pivotally supported on the teeth clutch via a bearing, and the other frame is slidably supported on a cylindrical support protruding from the side wall of the equipment. The slope of the spacer screwed onto a rotatably supported bolt is slidably engaged with the slope of the frame, and the shaft hole provided at the periphery of the frame is inserted, and the spring is inserted into the bolt screwed onto the side wall of the equipment. is wound around the spacer, and this spring applies a spring force to the frame in a direction in which the frame and each slope of the spacer come into pressure contact with each other.

Embodiments Hereinafter, embodiments of the clutch device according to the present invention will be described with reference to the drawings.

In FIG. 2, 1 is the shaft end on the driving side, and 2 is the shaft end on the driven side. The end surfaces of the respective shaft ends 1 and 2 face each other on the same axis with a gap 3 interposed therebetween. A pair of teeth clutches 5, 6 are fitted into the ends of each shaft 1, 2 in the middle of the gap 3, each having continuous teeth 4 on their inner surfaces and in meshing contact with each other.

The teeth clutch 5 on the driving side is fixed to the shaft end 1, while the teeth clutch 6 on the driven side is fitted so as to be movable in the axial direction using a spline 7 provided on the shaft end 2 as a guide.

The teeth clutch 6 on the driven side has an annular portion 8 of a frame 13 on the outer peripheral surface of a boss 6a projecting in the axial direction.
are integrally fitted through the bearing 9. Also,
Push plates 2 provided on each of the teeth clutches 5 and 6
The holes provided at 0 and 20a have spring receivers 12,
A bolt 10 screwed and fixed to the support frame 11 is inserted through the support frame 11. Further, the frame 13 protrudes toward the drive side and partially covers the teeth clutch 5.

On the other hand, an annular recess 14 is formed between the driving side support frame 11 and the teeth clutch 5.

In the recess 14, there is a frame 15 whose distal end face faces the distal end edge 13a of the frame 13 protruding toward the drive side, and a slope 1 provided on the outer surface of the frame 15.
A sliding spacer 17 joined to the frame 15 is screwed to the sliding spacer 17, and a fastening bolt 18 is provided to the frame 15. 19 is a collar at the lower end of the bolt.

A push plate 2 protrudes from the frame 13.
A bolt 10 provided on the outside of the frame 13 is inserted through the bolt 10, and this push plate 20 and the spring receiver 1
2 is a push spring 21 inserted into the bolt 10.
is installed.

In the above configuration, when the pair of teeth clutches 5 and 6 are coupled to interrupt the driving force transmitted from the driving side shaft end 1 to the driven side shaft end 2, an impact is applied to the head of the bolt 18 by remote control. By fitting a wrench and turning the bolt 18, the sliding spacer 17 is moved down along the slope 16 of the frame 15. As a result, the frame 15 moves to the left in FIG.
and press it to move the frame 13 to the left. At this time, the frame 15 can move by the width l without colliding with one of the teeth clutches 5, and since the frame 13 is integrated with the teeth clutch 6 on the driven side as described above,
As the frame 13 moves, it moves in the same direction, and as a result, the teeth clutch 6 is separated and the two shaft ends 1 and 2 are disengaged.

Conversely, when the bolt 18 is turned in the direction of loosening by remote control, the frame 13 moves to the right in the figure together with the frame 15 due to the return force of the push spring 21, and engages the teeth clutches 6 and 5, which had been separated. The shaft ends 1 and 2 are connected.

As explained above, according to the clutch device of the present invention, the pair of teeth clutches provided between the two shafts can be freely engaged and disengaged by simply operating the bolt, so that the driven Not only does it facilitate maintenance and inspection of rotating equipment driven by the side, it can also be installed in a narrow space, and is particularly suitable for connecting and separating shafts by remote control. In addition, the teeth clutch is constructed so that its contact surfaces mesh with each other through a large number of teeth, so even if a phase shift occurs, it can be easily corrected, and the clutches are perfectly connected to each other, preventing slippage. Therefore, the driving force on the driving side is transmitted to the driven side without loss, making it extremely efficient.
