Description

[Detailed description of the invention] This invention has two sets of electromagnetic clutch mechanisms arranged in parallel between the input shaft and the output shaft, and by coupling one or the other of these mechanisms, the rotational force of either forward or reverse tilting is applied to the output shaft. This relates to a reversible electromagnetic coupling device that can easily obtain forward and reverse rotations, shorten the axial dimension of the entire device, and have different rotational speeds in the forward and reverse directions. The purpose of the present invention is to provide a device that can also take out the information at a ratio.

Next, an embodiment of the present invention will be described with reference to the drawings.

In the drawing, 1 has a gear integrally formed with an input shaft, and is supported concentrically on an output shaft 2 via a bearing 3.

A first rotor 4 is supported on the output shaft 2 via a bearing 5 and is integrally connected to the input shaft 1 at a boss portion.

Reference numeral 6 denotes a non-magnetic ring that magnetically separates the outer circumferential portion and the inner circumferential portion of the first rotor 4 .

I is an electromagnet body having an electromagnetic coil 8, which is fixed to the outer frame 9, and the first rotor 4 is opposed to the magnetic pole part with a required magnetic gap in between.

10 is dynamically connected by a spline to a knob 11 fitted on the output shaft 2 at a first armature opposite to one side of the tenth motor 4 at one side.

12 is a button on the outer circumference and is connected to the outer circumference of the first rotor 4, and a 20th rotor arranged in parallel with the first rotor has a button on the inner circumference via the sleeve bearing 13 and is connected to the outer circumference of the first rotor 4. Supported.

The hub 14 is supported on the output shaft 2 via a bearing 15.

Reference numeral 16 denotes a ring of non-magnetic material provided between the outer and inner circumferences of the 20th rotor 12 to magnetically separate the outer and inner circumferences.

Reference numeral 17 denotes an electromagnet having a t-magnetic coil 18, which is fixed to the outer frame 9.

A second armature 19 has a button on its inner peripheral edge and is spline-coupled to the hub 14, and is opposed to one side of the 20th armature 12.

Although both the first armature 10 and the second armature 19 are not shown, a return spring such as a leaf spring is provided between the pulleys 11 and 14, and current is supplied to the electromagnetic coils 8, 18. When the rotors 10 and 12 are not in place, the rotors 10 and 12 are separated by the action of the springs, thereby creating a required gap between them.

20 is a gear coupled to the hub 14, 21 is a gear coupled to the output shaft 2, 22, 23, 24 is a series of intermediate gears, and gears 22 and 23 are integrally formed and supported by the outer frame 9. supported by a shaft 25, one gear 2
2 meshes with the gear 20 mentioned above.

The gear 24 is supported by a shaft 26 supported by the outer frame 9, and meshes with the gears 21 and 23.

In the above configuration, the input shaft 1, the 10th
Normally, the three members, the 20th armature 12 connected thereto, receive power from a prime mover and are constantly rotated, and when feeding power to one electromagnetic coil 8, the first armature 10
is attracted to the 10th rotor 4 side and is brought into pressure contact with the friction surface formed on one side of the rotor, and the rotation of the 10th rotor 4 is transmitted to the hub 11 and further to the output shaft 2 via this armature. be done.

At this time, the speed and rotation direction of the output shaft 2 are the input shaft 1.
It is similar to that of .

Next, when the power supply to the electromagnetic coil 8 is cut off and current is supplied to the other electromagnetic coil 18 instead, the second armature 19 is attracted to the 20th-terminal 12 side, and that armature Pressed against 12 friction surfaces,
The rotation of the 20th gear 12 is transmitted to the hub 14 through this armature, and further to the gear 20 connected to the hub 14, and the gears 22, 23, 2 that mesh with this gear in sequence.
The signal is transmitted to the output shaft 21 via 4F and 21.

At this time, the rotation direction of the output shaft 20 is opposite to that of the input shaft 1, and the speed can be arbitrarily changed by appropriately selecting the ratio of each gear in a series that dynamically connects the hub 14 and the output shaft 2. can.

Of course, even if the input/output relationship between the input shaft 1 and the output shaft 20 is switched, the above-mentioned operation will still be the same.

In this case, by switching the energization to each electromagnetic coil, it is possible to easily extract the rotational force for forward or reverse tilting, and the speed for either forward or reverse is the same as the input shaft. Of course, it is possible to obtain an arbitrary speed different from that, and the input shafts are configured to concentrically overlap in the radial direction, and at the same time, the axial dimension of each clutch mechanism can be reduced as much as possible. It's possible, and also the 20th
- Since the rotor can be supported by a sleeve bearing or the like on the inner circumference, it is also possible to prevent the rotor from wobbling.
