The transmission mechanism includes a companion clutch mechanism for manual operation of the gate, and the clutch mechanism includes a clutch pressure plate, a bearing plate, and a spring mechanism, which spring mechanism controls the output mechanism. When a predetermined force is applied around the rotating shaft, the pressure plate is pressed against the bearing plate by a predetermined force, causing the clutch mechanism to slide, thereby allowing manual operation of the gate. be.

Preferably, the clutch ms is enclosed within a clutch housing, and this housing is preferably filled with a lubricating liquid. It has been Mt.

The transmitter 44 preferably includes a gear mechanism, and the bearing plate may be a gear wheel of the gear mechanism.

Preferably, the output mechanism, gear wheel and clutch pressure plate are mounted for rotation about a common axis.

Preferably, the output mechanism and the clutch pressure plate are fixed on a common shaft at the end of rotation, and the gear wheel is mounted on a shaft to provide relative rotational movement between the gear wheel and the shaft. preferable.

The gear wheel can be rotatably mounted on a mounting element fixed together with the shaft for rotation;
The gc attachment element creates an axial stop (axlal stop) against the axial movement of the gear wheel under the bias of the spring mechanism.
5top).

Preferably, the spring mechanism includes nine springs spaced apart around the axis of rotation of the pressure plate. They can be made from 4 to 10 springs, and 9 to 7 springs.

The gear wheel may be driven by a worm gear.

In addition to the gate opening/closing device according to the invention, the present invention also provides a motor for driving the entire device.

This motor can drive a worm wheel, and the worm wheel is a worm gear! !
Then, this will drive the +j'lJ5 self gear wheel.

[Gtai 101], one embodiment of the device according to the present invention will be described with reference to the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the drive device, generally designated by the symbol 1O, comprises a main body 11, which is a plate 12 mounted at ground level, set, for example, on concrete, with four locations. It includes a hole 13 formed therein.

A housing part 14 extends below the gear mechanism 12 for accommodating the gear mechanism.

The explanation of the mechanism and its operation will begin with the motor, drive Da1m, and end with the output from the device.

i of the device! The movement of the gate as well as the drive of the gate through the device is carried out by motor 15. Especially 1! It is convenient to do it based on motivation. The motor drives a worm gear within the motor casing 16, which in turn drives a ring gear 17 which is fixed for rotation with an input shaft 18 supporting the worm gear 19. Bolts 20 secure the housing 16 with the motor flange 21, and bolts 22 secure the motor 7 mount 21 with the end cap 23;
In the completed assembly, the tool/docker 23 is threadedly engaged with the housing portion 14. The oil seal 24 is fitted onto the shaft 18 and a bearing 25. In this case, the ball bearing supports the shaft 18i, and the four-wheeled gear 17 rotates together with the shaft 18.

It is fixed by a wedge 26.

The end of the shaft 18 remote from the ring gear 17 is the second
The housing part 1 is supported in the housing part 1.
4 and is supported by an end cap 28 which is threadedly engaged with the end cap 28.

The worm gear 19 is rotatably mounted on the boss 31 and fitted with the nine worm wheels 3o. Boss 31 is 1
It is mounted on the output shaft 32 at @, and '! The boss 31 is fixed to a wedge 33 at the ninth position to be rotated together with the output shaft 32.

The output shaft 32 is mounted for rotation within the housing portion 14 by upper and lower bearings 34 and 35, respectively, in this case using ball bearings. Lower bearing 35 is supported within housing cover 36.

Below the worm wheel 30, a clutch pressure plate 40 is secured to a wedge 41 for rotation with the boss 31.

Below the pressure plate 40, a spring base 42 is secured to the boss 31 by a ring nut 43 threaded into the lower end of the boss 31. - the coil springs 44 of the set engage recesses 45 in the pressure plate 40;

These springs 44 act on the spring base 42 and the pressure plate 40 to force the worm wheel 307 . Press H to frictionally engage with the boss 31. Spring base 42Fi again. It has a recess formed within it.

It is further engaged by a spring 44 to prevent movement and sliding of the spring.

The first seals 50 and 51 of 21 are blank.

The cap 52 seals the chamber surrounding the worm wheel mechanism and lubricates the chamber.

9. Provided in close proximity to the chamber, for example for filling with lubricating oil.

The upper end of the shaft 32 has an output arm 60 secured by a wedge 61 for rotation with the shaft 32.
I fully support it. Bolts 62 serve to secure output arm 60 to shaft 32 and cap 63 is lowered onto the free end of shaft 32.

The output arm 60 is secured to the gate in use.

Finally, the lower cover 70 is attached to the bolt 71 and the plate 12
It sticks to.

In full description, the motor 15 drives the shaft 18, and the worm gear 19 on the shaft 18 drives the worm gear 30 to rotate the output shaft 32' (i-), thereby turning the associated gate. When manual opening and closing of the associated gate is required, the clutch assembly is rotated around the axis of rotation of the gate by means of a boss 31 and a clutch pressure plate 40 that slides against a worm wheel 30. Once you reach a predetermined moment, you can hold your entire jaw.

This kind of manual operation is totally acceptable. Although the strength of the spring 44 determines the moment required to cause the clutch assembly to slip, the advantage of this assembly is that it is highly reliable and allows full manual operation of the associated gates without failure. .
