Abstract

PURPOSE:To obtain a large speed reducing ratio in a small-sized gear by feeding and rotating the second gear for a difference in the number of teeth between the first gear and the second gear, and transmitting the rotation to the second shaft. CONSTITUTION:If a difference in the number of teeth between the first gear 15 and the second gear 16 is one, a turn of the engaging portion causes the second gear 16 to rotate for one tooth which is the difference in the number of teeth. As the second gear 16 serves as another rotary carrier, the movement of another turning projection 22 is caused. Accordingly, the movement of the turning projection 22 is performed at a speed which is reduced according to the difference in the number of teeth between the first gear 15 and the second gear 16, so that a speed reducing effect at a large ratio can be obtained.

In addition, it is pivoted so that it can rotate and tilt. Since this first gear 15 is supported by the first thrust bearing 12 having a spherical periphery as described above, it can be pushed by the rotation protrusion 7 and tilted so as to tilt its axis. .

を兼ねることになる。A second gear 16 is supported by the radial ball bearing 13 so that it can only rotate freely with respect to the second shaft 10 . The second gear 16 is formed with teeth 21 having a different number of teeth than the teeth 20 of the first gear 15 so as to go around the circumferential edge of the side surface facing the first gear 15. It is designed so that it can mesh with 15 teeth 20. The axial position of the second gear 16 on the second shaft 10 is such that when the first gear 15 is pushed by the rotation protrusion 7 and its axis is tilted, some of the teeth 20 are The position shall be such that it can inject into a part of 21. The second gear 16 also has the rotation protrusion 7 on the side opposite to the side on which the teeth 21 are formed.
A rotating protrusion 22 separate from the above is provided in a protruding manner. Then,
This second gear 16 also serves as a rotary carrier different from the rotary carrier 6.

されている。In the second thrust bearing 14, there is another first gear 15 having exactly the same configuration as the first gear 15 described above, at the same relative position with respect to the rotation protrusion 22 of the second gear 15 which also serves as a rotation carrier, and in the same manner. It is supported in such a way that the shaft center can only be tilted, but not rotated due to the interference between the rotation stop projection 17 and the rotation stop groove 1).

The teeth 20 are also fixed integrally in the axial direction, and when the first gear 15 facing the first gear 15 tilts, the teeth 20
It is designed to be able to mesh with 1. It goes without saying that the second gear 16 has a number of teeth equal to the number of teeth of the first gear 15 that meshes with it.

かくして、この実施例の場合は、２段の減速機構となっ

駆動されるようになっている。Thus, in this embodiment, a two-stage speed reduction mechanism is provided, and the second shaft 10 is driven to reduce speed by the second gear 16 at the end.

さて、次にこの実施例の動作を説明する。Next, the operation of this embodiment will be explained.

ている。When the first shaft 3, which also serves as the motor output shaft of the motor M, rotates, the rotation carrier 5 rotates, and the rotation protrusion 7 rotates. This rotation protrusion 7 pushes the first gear 15 while rotating. As a result, the first gear 15 tilts its axis and performs a so-called tilting motion. At this time, the first gear 15 is prevented from rotating by the rotation stop groove 1) and the rotation stop projection 17.

而して、第１歯車１５は、傾動運動をしながらその歯２
０を第２歯車１６の歯２１に部分的に噴合し、しかも、
その噛合部分は、前記回動突起７の回動速度、換言すれ
ば傾動の方向が変わる速度で巡回する。Thus, the first gear 15 rotates its teeth 2 while making a tilting motion.
0 is partially injected into the teeth 21 of the second gear 16, and
The engaging portion rotates at the rotation speed of the rotation protrusion 7, in other words, at the speed at which the direction of tilting changes.

そして、この場合、例えば第１歯車１５と第２歯車１６

ているので、別の回動突起２２の回動を惹起し、また、
その別の回動突起２２の回動は、前述の第１歯車１５と
第２歯車１６の歯数の差で減速された速度となる。この
減速された回動突起２２の回動は、その速度の更に別の
第１歯車１５の傾動運動を惹起し、この第１歯車１５が
更に別の第２歯車１６に対して前述と同様に噛合する。In this case, for example, the first gear 15 and the second gear 16
If the difference in the number of teeth is only one, the second gear 16 will rotate by the difference in the number of teeth by one when the meshing portion completes one cycle. Since this second gear 16 also serves as another rotation carrier, it causes another rotation protrusion 22 to rotate, and also
The rotation of the other rotation protrusion 22 has a speed reduced by the difference in the number of teeth between the first gear 15 and the second gear 16 described above. This reduced rotation of the rotation protrusion 22 causes a tilting movement of the further first gear 15 at its speed, which first gear 15 relative to the further second gear 16 in the same way as before. mesh.

かくして、第２歯車１６は、これに噛合する第１歯車１
５との歯数の差で、前述と同様に減速回転する。Thus, the second gear 16 meshes with the first gear 1.
Due to the difference in the number of teeth from 5, it rotates at a reduced speed in the same way as described above.

この最終の第２歯車１６は、第２軸１０に固定されてい
やので、第２軸が、この場合、２段に減速されて回転す
ることになる。Since this final second gear 16 is not fixed to the second shaft 10, the second shaft rotates at a speed reduced in two stages in this case.

ここで、この実施例の減速の原理を、いま少し詳細に説
明する。Here, the principle of deceleration in this embodiment will be explained in some detail.

まず、この形式の歯車噛合では、回動突起７が時計方向
に回るとして、第１歯車１５の歯数が第２歯車１６のそ
れより少ないときは、第２歯車１６は反時計方向に、ま
た、その逆の歯数のときは、時計方向に、回転すること
になる。First, in this type of gear meshing, assuming that the rotation protrusion 7 rotates clockwise, when the number of teeth of the first gear 15 is smaller than that of the second gear 16, the second gear 16 rotates counterclockwise or , if the number of teeth is the opposite, it will rotate clockwise.

そして、次に減速比は、第１歯車１５の歯数をＮ１とし
、第２歯車１６の歯数をＮ２とすれは、ＩＮＩ　−Ｎ２
１ 減速比＝□ となり、 また第１歯車１５と第２歯車１６との対が複膜となる場
合は、その分母の段数ｎ乗した式によって表される。つ
まり、 ＩＮＩ　−Ｎ２＋ 減速比−□□ へ となる。Next, the reduction ratio is INI - N2, where the number of teeth of the first gear 15 is N1 and the number of teeth of the second gear 16 is N2.
1 Reduction ratio=□, and when the pair of the first gear 15 and the second gear 16 is a compound membrane, it is expressed by an expression where the denominator is raised to the nth power of the number of stages. In other words, INI -N2+ Reduction ratio -□□.

したがって、例えは、第１歯車１５の歯２０の数を３０
とし、第２歯車２１の数を２９としたときは、第１歯車
１５の第２歯車１６への噛合部分が一巡すると、歯の数
で１／３０の割合で送られて減速回転する。そして、次
の段の第１歯車１５と第２歯車１６の対を経て、第２軸
は１／９０の割合で送られて減速回転する。Therefore, for example, the number of teeth 20 of the first gear 15 is 30.
When the number of second gears 21 is 29, when the meshing portion of the first gear 15 with the second gear 16 completes one cycle, it is fed at a rate of 1/30 of the number of teeth and rotates at a reduced speed. Then, through the pair of first gear 15 and second gear 16 in the next stage, the second shaft is fed at a rate of 1/90 and rotates at a reduced speed.

この実施例は、ギヤドモータとして説明されているが、
減速装置そのものとして、別の原動機と組合せてもよい
ことは勿論である。Although this embodiment is described as a geared motor,
Of course, the reduction gear itself may be combined with another prime mover.

ように連絡してある減速装置を有するギヤドモータ。(5) A pair of first and second gears that have different numbers of teeth and mesh with each other, and a first and second shaft that sequentially decelerate and transmit power through this pair of gears. In the geared motor, the geared motor has a reduction gear having a speed reducer, and the first shaft is the motor output shaft, and the first shaft and the second shaft are supported on the same axis so that they can rotate independently. A rotary carrier is supported on the first shaft and/or the second shaft so as to be able to rotate around the axis by the rotational force of the power source, and the rotary carrier has a rotary carrier that rotates in the axial direction. an extending pivot projection is carried, the first gear and the second gear having intermeshed teeth on opposite sides thereof;
The gear is supported on the axis so as to be able to tilt its axis by being pushed by the rotating protrusion on a side opposite to the side on which the teeth are formed, and not to rotate. The shaft is disposed on an axial extension of the first shaft so as to be able to rotate independently of the first shaft, and the second gear is arranged so that the first gear tilts its axis and rotates at a position closest to the first gear. A geared motor, the geared motor having a speed reducer fixed at least axially to the second shaft at an axial position where the gears can be engaged with each other by the gears alone, and connected to the second shaft so as to transmit power. （６）第２軸の一端部は、第１軸に担持されている軸受
