Description

[Detailed Description of the Invention] a. Industrial Application Field The present invention relates to a flex gyroscope;
In particular, it relates to a novel improvement which allows vertical springs to be inserted into horizontal springs very easily without any deformation.

b. Prior Art Various configurations have been proposed for this type of flex gyroscope that has been used in the past.
Typical configurations are shown in FIGS. 3 and 4.

That is, in FIGS. 3 and 4, the reference numeral 1
1 is a horizontal spring that has a cross shape as a whole and is made of plate material, and this horizontal spring 1 is integrally formed with four horizontal spring pieces 1a, and each of these horizontal spring pieces 1a has a A holding slit 1b is formed in each of the holding slits 1b in the longitudinal direction.

As shown in FIG. 4, the holding slits 1b formed in the horizontal spring piece 1a are closed at both ends, and the vertical springs 2 are fitted into these holding slits 1b. The engaging portion 2a of each vertical spring 2 is engaged with and held by the locking portion 1c of the holding slit 1b.

An outer ring 5 consisting of an upper outer ring piece 3 and a lower outer ring piece 4 is provided at the outer end of the horizontal spring 1 so as to sandwich the horizontal spring 1.
A slit 5a for letting the engaging portion 2a of the vertical spring 2 escape is formed at a position corresponding to the holding slit 1b.

Although the outer ring 5 is formed into a ring shape in the configuration shown in FIG. 3, it is finally cut into four parts to form four outer rings as shown in FIG. Furthermore, a gyroscope rotor (not shown) is attached to the outside thereof.

A gimbal 6 as an inner rotor consisting of a pair of gimbal pieces 6a and 6b is provided at the center of the horizontal spring 1.

The conventional flex gyroscope is constructed as described above, and when actually assembled, each vertical spring 2 is fitted into each holding slit 1b in the state shown in FIG. Both ends of the vertical spring 2 are connected to an outer ring 5.
is guided and held by the slit 5a of the gimbal 6 and the gimbal slit 6c of the gimbal 6.

c Problems to be solved by the invention Since the conventional flex gyroscope is configured as described above, the horizontal spring 1
When installing each vertical spring 2 in each holding slit 1b, since both ends of each holding slit 1b are closed as shown in FIG. If this vertical spring 2 is not slightly deformed, the retaining slit 1b
It was not possible to fit it inside.

Therefore, when fitting the vertical spring 2 into the holding slit 1b, the vertical spring 2 may be deformed, and the accuracy of the hinge mechanism using the horizontal spring and the vertical spring may be reduced. It was becoming impossible to obtain the basic characteristics of a gyroscope.

The present invention quickly eliminates the above-mentioned problems, and without deforming the vertical spring,
The object is to obtain a flex gyroscope that can be attached to a horizontal spring very easily.

d Means for solving the problem The flex gyroscope according to the present invention has the following features:
A horizontal spring having a cross shape as a whole and having four holding slits in the radial direction, an open slit formed at the end of each holding slit and passing outward, and a gimbal provided in the center of the horizontal spring. , a vertical spring provided in each holding slit of the horizontal spring, and four outer ring pieces provided at the ends of the horizontal spring and having slits corresponding to the holding slits.

e Effect In the flex gyroscope according to the present invention, when each vertical spring is attached to each holding slit of the horizontal spring, when the vertical spring is inserted from the outside of the outer ring piece through the slit, the vertical spring is attached to the slit and the horizontal spring. It is inserted and held in the holding slit via the open slit.

Therefore, the vertical spring can be attached to the horizontal spring from the outer side of the outer ring piece without any deformation by only horizontal movement, and a hinge mechanism as designed can always be obtained.

f. Embodiments Hereinafter, preferred embodiments of the flex gyroscope according to the present invention will be described with reference to the drawings.

Note that the same or equivalent parts as in the conventional example will be described with the same reference numerals.

1 and 2 are for showing a flex gyroscope according to the present invention. In the drawings, the reference numeral 1 indicates a horizontal spring having a cross shape as a whole and made of plate material. This horizontal spring 1 is integrally formed with four horizontal spring pieces 1a, and each of these horizontal spring pieces 1a is formed with a holding slit 1b in its longitudinal direction.

The holding slit 1b formed in the horizontal spring piece 1a has an open slit 1d formed at its end, as shown in FIG.
and communicates with the outside.

A locking portion 1c is formed at the inner end of the holding slit 1b, and a vertical spring 2 is fitted into the holding slit 1b, and the engaging portion 2a of each vertical spring 2 engages the holding slit 1b. It is held by engaging with the portion 1c and the open slit 1d.

An outer ring 5 consisting of an upper outer ring piece 3 and a lower outer ring piece 4 is provided at the outer end of the horizontal spring 1 so as to sandwich the horizontal spring 1. A slit 5a through which the vertical spring 2 escapes is formed at a position corresponding to 1b. This slit 5a is formed across each outer ring piece 3 and 4, and the height _H1 of this slit 5a and the height _H2 of the vertical spring 2 are almost the same,
The vertical spring 2 is configured to be inserted and positioned within the slit 5a.

The outer ring 5 is formed into a ring shape in the configuration shown in FIG. 1, but as shown in FIG.
A gyro rotor (not shown) is attached to the outside of the outer ring piece 5b.

A gimbal 6 as an inner rotor consisting of a pair of gimbal pieces 6a and 6b is provided at the center of the horizontal spring 1.

The flex gyroscope according to the present invention comprises:
It is configured as described above, and when actually assembled, the vertical spring 2 can be inserted from the outside of the outer rotor 5 in the state shown in FIG. The vertical spring 2 has a slit 5a.
The engaging portion 2a of the vertical spring 2 is inserted into the holding slit 1b through the opening slit 1d.
It engages with the locking portion 1c of the holding slit 1b and the opening slit 1d, and the connection between the horizontal spring piece 1a and the vertical spring 2 is completed.

g. Effects of the invention The flex gyroscope according to the invention has the following features:
Since it has the above structure and function, the vertical spring can be attached to the horizontal spring.
After all other parts except the vertical spring have been assembled, the connection between the horizontal and vertical springs can be completed by simply inserting the vertical spring from the outside of the outer rotor, without deforming the vertical spring in any way. , can be mounted on horizontal springs.

Therefore, when assembling a flex gyroscope, it is possible to complete the installation extremely easily without damaging or deforming the vertical springs, unlike in the past. The mechanism can be assembled as designed, and a flex gyroscope with high precision and good yield can be obtained.
