Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein a planetary transmission for transmitting repetitively positive-reverse rotation such as rocking motion has been only capable of transmitting repetitively positive-reverse rotations depending on input rotation or transmitting single-side rotation via a one-way clutch or a ratchet incorporated therein. <P>SOLUTION: This planetary transmission is constructed with two-stage planetary gears mounted on a carrier. The first-stage one generally consists of an inside sun gear 2, a planetary gear 3, and an outside internal gear 4. The second-stage one consists of a sun gear 5, two planetary gears 6a, 6b combined, and an outside internal gear 7 in combination. One-way clutches 8 are incorporated in the two sun gears 2, 5 to transmit the rotation of them to a center shaft 9 in the same direction. Even in the repetitively positive-reverse rotation of the carrier, one of the one-way clutches transmits the rotation to actualize rotation in one direction consistently. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、正逆回転を常時一方向の回転として出力する遊星変速機に関する。 The present invention relates to a planetary transmission that always outputs forward / reverse rotation as rotation in one direction.

正逆回転を常時一方向回転として出力する遊星減速機はなかった。 There was no planetary reduction gear that always outputs forward and reverse rotation as one-way rotation.

正逆回転を常時一方向回転として出力する遊星変速機を提供する。 Provided is a planetary transmission that always outputs forward / reverse rotation as one-way rotation.

遊星変速機の１箇所にワンウェイクラッチを組み込んだ遊星ギアを組み込むことで、正逆回転を常時一方向の回転として出力する。 By incorporating a planetary gear incorporating a one-way clutch at one location of the planetary transmission, forward and reverse rotation is always output as one-way rotation.

遥動運動のような正逆回転を常に一方向の回転として取り出すことができる。 Forward / reverse rotation such as swaying motion can always be extracted as one-way rotation.

本装置は、遊星変速機のキャリアー１に取り付ける遊星歯車を２段にする構造を１箇所持つ。１段は、通常通り、内側に太陽歯車２、そして遊星歯車３、そして外側の内歯車４からなる。もう１段は、太陽歯車５、そして２個の遊星歯車６ａ、遊星歯車６ｂの組み合わせ、そして外側の内歯車７の組み合わせからなる。２つの太陽歯車は、ワンウェイクラッチ８を組み込み中央の軸９に回転を伝える。 This device has one structure in which the planetary gear attached to the carrier 1 of the planetary transmission has two stages. One stage consists of a sun gear 2 on the inside, a planetary gear 3 on the inside, and an internal gear 4 on the outside as usual. The other stage consists of a sun gear 5, a combination of two planetary gears 6a, a planetary gear 6b, and a combination of an outer internal gear 7. The two sun gears incorporate the one-way clutch 8 and transmit the rotation to the central shaft 9.

増速機の場合、ワンウェイクラッチ８は同じ方向に回転を伝えるように取り付ける。入力軸１０より回転が伝わると、キャリアー１が回転し遊星歯車３、または遊星歯車６ａ、遊星歯車６ｂが回り、太陽歯車２、太陽歯車５が回り回転を伝えていくが、Ａ−Ａ断面とＢ−Ｂ断面では、太陽歯車２と太陽歯車５の回転が反対となる。ワンウェイクラッチ８をＡ−Ａ断面、Ｂ−Ｂ断面とも太陽歯車２、太陽歯車５が時計回転に回ったとき回転を伝えるように取り付けた場合、キャリアー１が時計回りに回転するとＡ−Ａ断面の太陽歯車２は、時計回りに回転し軸９に回転を伝える。Ｂ−Ｂ断面は、遊星歯車６ａ、遊星歯車６ｂがあるため、太陽歯車５の回転は、反時計回りになり、回転を伝えない。今度は逆に、キャリアー１が反時計回りに回転するとＡ−Ａ断面の太陽歯車２は反時計回りに回転し回転を伝えないが、Ｂ−Ｂ断面の太陽歯車５は、時計回りに回転し回転を伝える。よって、時計回りの回転、反時計回りの回転を繰り返しても、出力回転は常に時計回りとなる。 In the case of a gearbox, the one-way clutch 8 is attached so as to transmit rotation in the same direction. When rotation is transmitted from the input shaft 10, the carrier 1 rotates and the planetary gear 3, or the planetary gear 6a and the planetary gear 6b rotate, and the sun gear 2 and the sun gear 5 rotate and transmit the rotation. In the BB cross section, the rotation of the sun gear 2 and the sun gear 5 is opposite. When the one-way clutch 8 is mounted so as to transmit rotation when the sun gear 2 and the sun gear 5 rotate clockwise in both the AA and BB sections, the carrier 1 rotates in the clockwise direction. The sun gear 2 rotates clockwise and transmits rotation to the shaft 9. Since the BB cross section includes the planetary gear 6a and the planetary gear 6b, the rotation of the sun gear 5 is counterclockwise and does not transmit the rotation. On the contrary, when the carrier 1 rotates counterclockwise, the sun gear 2 of the AA cross section rotates counterclockwise and does not transmit the rotation, but the sun gear 5 of the BB cross section rotates clockwise. Tell the rotation. Therefore, even if the clockwise rotation and the counterclockwise rotation are repeated, the output rotation is always clockwise.

減速機として使用する場合は、太陽歯車２、太陽歯車５に取り付けるワンウェイクラッチ８をそれぞれ反対の回転を伝えるように取り付ければ、常に一方向回転出力の減速機となる。 When used as a speed reducer, if the one-way clutch 8 attached to the sun gear 2 and the sun gear 5 is attached so as to transmit the opposite rotation, the speed reducer always outputs in one direction.
