Description

[Detailed description of the invention]

The present invention relates to a 1gL electromagnetic clutch device capable of multi-stage operation with a switching output of 1 sho between forward rotation at multiple speeds and reverse rotation at a predetermined speed. The electromagnetic and clutch devices capable of producing two different speeds have not yet been developed, and in order to achieve such a large number of speeds, a power transmission system with a transmission mechanism installed in the middle is required. On the other hand, office automation and ultra-high-performance copying machines have been developed using small computers.・Pri]・rhi progresses on the 4th page,
At least several types of outputs, y-required, high, 1, 2 outputs, and 0. There has been a strong desire to develop a multi-speed reverse 1E clutch device that can provide a reverse rotation output at a predetermined speed and is compact and requires a small installation space. The present invention provides a multi-speed town reverse electromagnetic clutch device that meets the above-mentioned demands, and has a coil suffix with a winding resistance.

A shaft 12 supporting the shaft 1'I is installed. Spring clutches C1 and 05 are connected to the endless chain 10.
chain wheel rotated by] 3, 171 is the input side rotating member, spring clutches C2+C3,
The spring clutches C6 and C7, which are fixed to the input shaft 4, are the input-side rotating members, and the spring clutches C6 and C7 are the input-side rotating members, which are fixed to the input shaft 4. Furthermore, spring clutches c, , C2, C3, c
, are gears 20, 2 supported on the input shaft 3'' so as to be freely rotatable.
1.22 and 23 are output side rotating members, and spring clutches C, 1, C11 and C7 are freely rotatably supported on the input shaft 4'', and gears 24, 25 and 26 are output side rotating members. On the other hand, the output shaft! gears 27 and 28 are supported so that they can freely rotate, and an armature 29 that can magnetically attract the rotor 6 is attached to the gear 27 via a torque transmission spring 30 that also serves as a return spring in the axial direction (rod movement). In addition, the armature 31, which can be magnetically attracted to the hub 7, is returned to the tooth IV28, and a torque transmission spring that also serves as a spring;

In addition, the JX2-shaped yield core 33 facing the back of the hub 6 is connected to the 24-nel 1B, and the annular field core 34 facing the back of the hub 7 is connected to the 24-nel 1B. Each of them is fixed to the panel iA. □ Speed change gear assembly IJ A is a member that integrally forms gears 35, 36.37°, 38.39.40, and gear 3

6 uses a chain wheel as the input side rotating member, and the other spring clutches C2, C3, C4, co, and C7 are).
There is a difference in that the rotary member is used as the input-side rotating member, but in both cases, a cylindrical part 43 containing a coil spool ring 42 with a winding habit is concentrically mounted so that it can freely rotate, and the inner part of each cylindrical member 43 is Hook 17 the outward bent portion 42A of the coil sedge ring 42 in the notch 44 formed on the circumferential surface.
Figure 7.5 shows details of the structure of a spring clutch. As a representative example of a spring clutch, a spring clutch C5 is shown in an enlarged half vertical cross section I for the first time. A plurality of locking claws 45 are provided protrudingly on the outer peripheral surface of the cylindrical member 43 of each spring clutch C7 to C7. In this embodiment, the locking claws 45 are provided as shown in FIG. On the other hand, one arm 47A of a lever 47 which is rotatably supported by a shaft 46 on the frame I side is attached to the latch claw 45. The lever 47 is a lever for other Sgeling clutches except for the one for Swing clutch C1, and a long hole 48 is formed in the arm 4713 for external power, so that the operating solenoid 49 can be moved.

In the device Kt of the present invention, which has a dual chain configuration, when the endless chain 10 is driven in the direction shown by the arrow in FIG. 2 by an external drive source, the chain wheels 13°14.41 are driven to rotate. At this time, if the lever 47 is engaged with the latch claw 45 of the cylindrical member 43 in all of the Sgeling clutches C, -C, the rotation of the cylindrical part (; Since the coil ring 1111 is loosened, torque is not transmitted from the input rotating member to the output rotating member.In other words, each of the rotating clutches 01 to C7 rotates the gear 27 on the output shaft. It is in an unprecedented state. On the other hand, if no voltage is applied to the electromagnetic coil 54 of the electromagnetic clutch D for reversing, the armature 31 is far away from the pin 7, and the chain wheel RA IJ' rotates 1-1.
Despite this, no rotation in the reverse □ direction occurs at output -9. That is, the output shaft 9. The solenoid 49 for any desired one of the clutches C1 to C7 is activated, and the cylindrical part 4 remains stopped.
When removed from the latch claw 45 of 3, the coil sill ring 42, which has a winding habit, is rotated by human power 1111.
Winding A is M' (1i, so both rotate together, 2, and the gear 27 is rotated at the desired rotational speed. J: Turns 1°. Apply voltage to the electromagnetic □ coil 53 and rotate the output shaft as long as possible. 9 does not rotate. □ Due to the state of the cow, the electromagnetic coil of the forward rotation electromagnetic clutch B) v 53 f'2: When voltage is applied, the output shaft 9 rotates at the desired speed, and the drum 8 Sacred Rope 5

Furthermore, to obtain the reverse rotation speed, the electromagnetic coil 5411 of the electromagnetic clutch D for reversing! Apply voltage to integrate the gear 28 with the output shaft 9. This is combined with C chain wheel 7, 1 □ f) 1 @ car, □
The gear 28 rotates in reverse, and the output shaft 9, which rotates together with the gear 28, rotates in the direction of the calyx. As is clear from the above explanation, the device of the present invention can obtain an output at a divine rotational speed corresponding to the number of Sgering Tarappu installed, and can be used for normal rotation. The structure, which includes an electromagnetic clutch, a reverse electromagnetic clutch, multiple spring clutches that transmit torque by tightening coil springs, a lever 4 that operates them, a solenoid, a speed change gear assembly, etc., is assembled and manufactured. It is easy to adjust the key 11ijH, and it also has excellent effects such as being able to be made smaller.
