Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a remote control device for a clutch that can be engaged or separated by a manual operating member.

Various types of clutches that can be remotely operated are known, such as electromagnetic clutches, hydraulically operated clutches, and pneumatically operated clutches.

However, such clutches designed for remote control cannot be operated manually.

Unlike the above-mentioned clutches exclusively for remote control, this device is a clutch remote control device that is attached to a clutch that has a manual operating member and moves the operating member using hydraulic or pneumatic pressure to perform remote control, and can also be operated manually. It provides:

The details of this invention will be explained below based on the attached drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a clutch case, and rotary shafts 2 and 3 are concentrically attached to both ends of the clutch case via bearings, respectively.

A rotating body 4 is fixed to the inner surface of one of the rotating shafts 2, and the inner surface of the rotating body 4 has a tapered inner circumferential surface 5.

Further, a disk-shaped mounting member 6 is formed near the inner end of the other rotating shaft 3, and a power transmission body 8 is attached to a plurality of bolts 7 fixed to this member 6 so as to be able to move forward and backward.

A tapered portion 9 covered with a suitable lining is provided on the outer periphery of the transmission body 8, and this tapered portion 9 matches the tapered inner circumferential surface 5 of the rotating body 4.

Each of the bolts 7 is provided with a spring 10 that pushes the transmission body 8 and presses the tapered portion 9 onto the tapered inner circumferential surface 5.

Further, a suitable cushioning rubber is inserted between another bolt provided on the mounting member 6 and the transmission member 8.

11 is a cylindrical body fixed to the transmission body 8, which is slidably fitted on the rotating shaft 3, and an angular bearing 12 is mounted on the outside of the cylindrical body.
is attached, and the sliding tube 13 is placed on the outside thereof.

14 is an arc-shaped swinging frame placed at the bottom of the sliding tube 13;
The shaft 15 provided on the outside of both ends is connected to the case 1 as shown in Fig. 2.
The push bolts 16 screwed into the upper portions of both ends of the swing frame 14 are brought into contact with the receiving pieces 17 on both sides of the sliding tube 13.

Reference numeral 18 denotes a manual operating member fixed to one end of the shaft 15 protruding outside the case 1, and an operating rod 19 is fixed to the upper part of the manual operating member.

A grip 20 is swingably attached to the upper end of the operating rod 19 as shown in FIG.

Reference numeral 21 denotes a notch installed in a side hole provided on the case 1 side of the member 18 so as to be able to move forward and backward.This notch 21 is supported by a spring 22 so as to project from the side surface of the member 18 on the case 1 side 21 and the grip 20 are connected to the wire 23
Connect with and turn the grip 20 toward the operating rod 19 to release
1 is pulled in against the spring 22.

In FIG. 4, 24 is a cover fixed to the side of the case 1, and the shaft 15 passes through this cover 24.

This cover 24 is provided with an engagement hole 25 in which the notch 21 protruding from the operating member 18 engages, this engagement hole 25 is communicated with a cylinder 26 provided in the cover 24, and a piston 27 fitted in this cylinder 26 is provided. A notch release pin 28 that fits into the engagement hole 25 is fixed to the front surface of the piston 27, and a return spring 29 is provided on the pin 28 side of the piston 27.

Reference numeral 30 denotes a fluid passage provided in the cover 24, the inner end of which communicates with the inside of the cylinder 26, and the outer end connected to a compressed air hose or hydraulic pipe via a joint 31.

In FIGS. 3 and 4, 32 is a cylinder mounting piece integrally formed on the outside of the cover 24, 33 is a cylinder fixed to this mounting piece 32, and 34 is a lid at the rear end.

Reference numeral 36 denotes a pushing member, the rear part of which serves as a large-diameter piston 35, which is slidably fitted into the cylinder 33.

Further, this pushing member 36 is loosely fitted into the central opening of the mounting piece 32.

37 is a push bolt screwed into the push member 36, and a hemispherical ball 37' is rotatably attached to a recess at the tip of the push bolt.
The flat surface of the operating member 18 is brought into close contact with the side surface of the operating member 18.

However, an ordinary bolt may be used, and the operating member 18 may be directly pushed by the pushing member 36 without using the push bolt 37 or the ball 37'.

Reference numeral 38 denotes an automatic flow rate adjustment valve provided on the lid 34, and a compressed air hose or hydraulic pipe is connected to the rear end of this valve 38 via a joint 39.

In the above embodiment, the rotating shaft 2 is on the driving side and the rotating shaft 3 is on the driven side, and the operating rod 19 is in the OFF state where the notch 21 is engaged with the engagement hole 25 as shown in FIGS. 2 and 4. As shown in FIG. 1, since the tapered inner circumferential surface 5 of the rotating body 4 and the tapered portion 9 of the transmission body 8 are separated from each other, rotation of the rotating shaft 2 by the prime mover is not transmitted to the rotating shaft 3.

To turn the above-mentioned OFF state into the ON state, hold the operating rod 19 and the grip 20 together, and when you firmly squeeze the grip 20, the wire 23 pulls the notch 21 against the spring 22, and the notch 21 provided on the cover 24 of the case 1 is pulled. Remove it from the retaining hole 25.

Since the transmission body 8 is always pushed toward the rotating body 4 by the elasticity of the spring 10, the notch 21 is inserted into the engagement hole 25 as described above.
When it comes off, the transmission body 8 moves due to the elasticity of the spring 10, and the tapered portion 9 on its outer circumference presses against the tapered inner circumference 5 of the rotating body 4.

Therefore, the rotation of the rotating shaft 2 is transmitted to the rotating shaft 3.

In addition, in the above-mentioned OFF state, when compressed air or pressure oil is sent from a pressure fluid source (not shown) to the rear of the cylinder 26 through the joint 31 and the passage 30, the piston 27 is pushed against the spring 29 by the pressure. Move forward and push back the notch 21 with the notch release pin 28 on the front side.

As a result, the notch 21 moves backward and disengages from the engagement hole 25, and at the same time, the clutch is turned on as in the case of manual operation.

Thereafter, fluid pressure is removed from inside the cylinder 26 and the pin 28 is returned.

Next, when the clutch is in the ON state, by simply grasping the operating rod 19 and moving it in the OFF direction, the push bolt 16 of the swing frame 14, which rotates together with the rod 19, pushes the receiving piece 17 of the sliding tube 13, causing the sliding tube to move. 13 is retreated together with the cylinder body 11 and the transmission body 8,
The tapered portion 9 is separated from the tapered inner circumferential surface 5 and turned off.

At this time, the notch 21 engages with the engagement hole 25.

In addition, in the case of remote control, compressed air or pressure oil can be connected to the fitting 3.
9. Let the flow flow into the rear part of the cylinder 33 through the automatic flow rate adjustment valve 38, and push the piston 35 forward, and the push bolt 37 at the tip of the piston will push the operating member 18 to turn off the clutch and engage the notch 21 in the same manner as manual operation. Engage with the matching hole 25.

After that, the pressure fluid is removed from the rear part of the cylinder 33, and the piston 35 is made free.

This device is turned on by the manual operation rod 19 as described above.
A clutch that is turned off can also be operated remotely using fluids such as compressed air or hydraulic pressure.

Therefore, the cylinder 26. 33
Provide a manual switching valve to control fluid flow to the
Or cylinder 26. By using a solenoid valve as the fluid control switching valve 33 and electrically operating the solenoid valve with a switch in the operation room, remote control can be performed very easily and reliably.
