Description

[Detailed description of the invention] Industrial applications The present invention relates to a spur gear meshing device.

2. Description of the Related Art It is generally known that a driving force transmission mechanism in a conventional car stereo, for example, is constructed by sequentially meshing a plurality of spur gears.

When the plurality of spur gears are to be meshed in order, the procedure shown in FIGS. 9 to 1 has been used, for example.

Hereinafter, an explanation will be given based on the drawings. As shown in FIG. 9, the second spur gear 3 is meshed with the first spur gear 2 rotatably supported by the pin 1.

At this time, as shown in Fig. 9, the second spur gear 3 is attached to the suction shaft 4 by the suction force of air or the suction force of the magnet, and is rotated by 40 rotations of the suction shaft, as shown in Fig. 9 (Bl). It is inserted into pin 5 like this,
It was meshed with the first spur gear 2. after that,
The suction shaft 4 is separated from the second spur gear 3, and the third spur gear 6 is suctioned by the suction shaft 4 as shown in FIG. 10 (Al). As shown in Figure 10 FB+, it was fitted into the pin 7 and meshed with the second spur tooth Xi3.Furthermore, the suction shaft 4 was inserted from the third spur gear 6, and the fourth The fourth spur gear 8 is sucked by the suction shaft 4, and while rotating the fourth spur gear 8, it is fitted into the pin 9 as shown in FIG.
It meshed with spur gear 6. -Problems to be Solved by the Invention However, when meshing the spur gears in the above procedure, the spur gear that is to be meshed later is rotated while the spur gear is already supported by the pin. However, it took a long time to fit together, and the workability was poor.

The present invention solves these problems, and aims to shorten the time required for meshing spur gears and improve workability.

Means for Solving the Problem In order to solve this problem, the present invention rotatably holds a spur gear rotated by a motor and another spur gear that meshes with the spur gear, and this other spur gear is connected to the spur gear. A moving body is provided to hold the gear so that it moves in the tangential direction of the circle of the gear, and the movement of the moving body brings another spur gear closer to the tangential direction of the circle of the spur gear, so that the other spur gear engages the spur gear. Combine,
The rotation of the spur gear by the motor is transmitted to another spur gear.

Function: With this configuration, it is possible to mesh a rotating spur gear by moving another spur gear to be meshed, and the time required for the meshing can be shortened compared to the conventional method, improving work efficiency. It is possible to improve the

EXAMPLE Hereinafter, an example of the present invention will be described based on aspect (2).

First, FIGS. 1 to 3(2) and FIGS. 4 to 6 show the procedure for meshing spur gears.

In the case shown in FIG. 1, a pin 12a 11 is attracted to the upper end of the first suction shaft 12 by an air suction force or a magnetic suction force, and is attached to the first suction shaft 12.
A first spur gear 13 fitted in is a motor provided on the side of the first suction shaft 12, and a pulley 14 provided on the rotating shaft 13a of this motor 13 and the first suction shaft 1
A belt 15 is wound around the motor 2 to control the rotation of the motor 13.
It is configured to transmit the information to the suction shaft 12 of. While the first spur gear 11 is being rotated through the first suction shaft 12 by the drive of the motor 13, the upper end of the second suction shaft 16, which is similar to the first suction shaft 12, is rotated. The second spur gear 17 that has been attracted and fitted into the pin 16a provided on the second suction shaft 16 is moved to the side of the first spur gear 11 integrally with the second suction shaft 16, and as shown in FIG. As shown in (B), the second spur gear 17 is meshed with the first spur gear 11.

This is busy, the rotation of the first spur gear 11 is the second spur gear 1.
7, these two spur gears 11 and 17 rotate together.

At this time, the second suction shaft 16 also rotates. Next, Figure 2 (
In 5), a third spur gear 19 is attracted to the upper end of a third suction shaft 18 similar to the suction shaft 12.16, and this third spur gear 19 is attached to a pin provided on the third suction shaft 18. 18a, move the third spur gear 19 integrally with the third suction shaft 18 to the second spur gear 17 side, and move the third spur gear 19 as shown at 26CB+. It meshes with the second spur gear 17. As a result, the rotation of the second spur gear 17 is transmitted to the third spur gear 19, and the first to third spur gears 11, 17, and 19 rotate together.

At this time, the third suction shaft 18 also rotates. Furthermore, in FIG. 3 (3), a fourth spur gear 21 is attracted to the upper end of a fourth suction shaft 20 similar to the suction shafts 12, 16, and 18, and this fourth spur gear 21 is attached to the fourth suction shaft 20. The fourth spur gear 21 is inserted into the pin 20a provided on the suction shaft 2°.
is moved integrally with the fourth suction shaft 20 to the third spur gear 19 side, and the fourth spur gear 21 is moved as shown in FIG. 3(2).
meshes with the third spur gear 19. This allows the third
The rotation of the spur gear 19 is transmitted to the fourth spur gear 21, and the rotation of the first spur gear 19 is transmitted to the fourth spur gear 21.
~The fourth spur gears 11, 17, 19, and 21 rotate together. At this time, the fourth suction shaft 2o also rotates.

Note that the second to fourth spur gears 17 are shown in FIGS. 4 to 6.
, 19 and 21 are moved to mesh with the front spur gear in a plan view, and the spur gears 17 and 21 are moved.
19 and 21 are moved in the tangential direction of the circle of the front spur gear and are meshed in order.

Therefore, each of the suction shafts 12, 16, 18°2o is connected to a guide rod 22, as shown in FIGS. 7 and 8.
The motor 13 is rotatably attached to the tips of movable bodies 26 to 29 that are movable along the axis 25, and the motor 13 is attached to the movable body 26 that supports the first suction shaft 12. 30 to 33 guide the movable bodies 26 to 29 to the guide rod 2
This is a cylinder that serves as a driving source when moving along lines 2 to 25.

Effects of the Invention As described above, according to the present invention, meshing can be performed by moving the spur gears to be meshed, and the time required for the meshing can be shortened compared to the conventional method, improving workability. You can improve your performance.
