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.
