このねじれ角は以下のようにして求められる。 This twist angle is determined as follows.
第5図に示すように、入力軸2が回転し、大歯
車25がx°回転すると、その円周はx/(360)×
πd25だけ進む。各歯車の厚みはT=const.である
ので、大歯車25のねじれ角をβ25とすると、
T/x/360×πd25=tanβ25 ……(1)
となる。 As shown in Fig. 5, when the input shaft 2 rotates and the large gear 25 rotates x degrees, its circumference becomes x/(360) x
Advance by πd 25 . Since the thickness of each gear is T=const., if the helix angle of the large gear 25 is β25 , then T/x/360× πd25 = tanβ25 (1).
これに対して、小歯車24もx°回転するので、
小歯車24のねじれ角をβ24とすると、
T/x/360×πd24=tanβ24 ……(2)
となる。 On the other hand, since the pinion 24 also rotates x°,
If the helix angle of the pinion 24 is β 24 , then T/x/360×πd 24 =tanβ 24 (2).
(1)、(2)式より、 d25/d24=tanβ24/tanβ25 ……(3) となる。 From equations (1) and (2), d 25 /d 24 =tanβ 24 /tanβ 25 ...(3).

つて、入力側ギア23、入力軸2の第1軸部21
および第2軸部22が回転し、小歯車24および
大歯車25が回転する。 As shown in FIG. 1, the second shaft portion 22 of the input shaft 2
When a switch (not shown) is turned on while the motor is in the first position, the motor M rotates and the worm gear G1 rotates. Due to the rotation of the worm gear G1, the input side gear 23 and the first shaft portion 21 of the input shaft 2
Then, the second shaft portion 22 rotates, and the small gear 24 and the large gear 25 rotate.
大歯車25の回転によつて、小歯車31、出力
軸3および駆動ピニオン33が回転する。該駆動
ピニオン33の回転が開閉体の駆動機構に伝達さ
れ、開閉体が駆動される。 The rotation of the large gear 25 causes the small gear 31, output shaft 3, and drive pinion 33 to rotate. The rotation of the drive pinion 33 is transmitted to the drive mechanism of the opening/closing body, thereby driving the opening/closing body.
一方、小歯車24の回転によつて、第1変速ギ
ア42、軸41、第2変速ギア43およびカムギ
ア44が回転する。ここで、第2変速ギア43の
歯数が第1変速ギア42の歯数より少なくなつて
いるので、カムギア44の回転速度は、入力軸2
の第2軸部22の回転速度とは異なつている。 On the other hand, the rotation of the small gear 24 causes the first transmission gear 42, shaft 41, second transmission gear 43, and cam gear 44 to rotate. Here, since the number of teeth of the second transmission gear 43 is smaller than the number of teeth of the first transmission gear 42, the rotation speed of the cam gear 44 is lower than that of the input shaft 2.
The rotational speed of the second shaft portion 22 is different from that of the second shaft portion 22 .
したがつて、第2軸部22とカムギア44との
間に相対的な回転変位が生じ、第2軸部22の突
起22aがカムギア44のカム溝45内を移動す
る。 Therefore, a relative rotational displacement occurs between the second shaft portion 22 and the cam gear 44, and the protrusion 22a of the second shaft portion 22 moves within the cam groove 45 of the cam gear 44.
すなわち、開閉体が全閉位置から全閉位置近傍
までの範囲外に位置している時には、突起22a
がカム溝45の第1水平溝45a内で移動してお
り、入力軸2の第2軸部22が第1位置に保持さ
れている。 That is, when the opening/closing body is located outside the range from the fully closed position to the vicinity of the fully closed position, the protrusion 22a
is moving within the first horizontal groove 45a of the cam groove 45, and the second shaft portion 22 of the input shaft 2 is held at the first position.
したがつて、第2軸部22の大歯車25が出力
軸3の小歯車31に噛合し、入力軸2の回転が増
速されて出力軸3に伝達される。 Therefore, the large gear 25 of the second shaft portion 22 meshes with the small gear 31 of the output shaft 3, and the rotation of the input shaft 2 is accelerated and transmitted to the output shaft 3.
そして、開閉体が前記範囲に近づくと、突起2

斜溝45c内を第2水平溝45bに向つて移動す
る。この移動によつて入力軸2の第2軸部22が
第1位置から第2位置に向つて変位する。 When the opening/closing body approaches the above range, the protrusion 2
2a enters the inclined groove 45c of the cam groove 45 and moves within the inclined groove 45c toward the second horizontal groove 45b. This movement causes the second shaft portion 22 of the input shaft 2 to be displaced from the first position toward the second position.
開閉体が前記範囲内に入つた時点で、突起22

力軸2の回転が減速されて出力軸3に伝達される
ので、大きな駆動力が出力軸3に伝達される。 When the opening/closing body enters the range, the protrusion 22
a enters the second horizontal groove 45b, and the displacement of the second shaft portion 22 toward the second position is completed. Due to this displacement, the large gear 25 of the second shaft portion 22 is disengaged from the small gear 31 of the output shaft 3, and the small gear 24 of the second shaft portion 22 meshes with the large gear 32 of the output shaft. As a result, the rotation of the input shaft 2 is decelerated and transmitted to the output shaft 3, so that a large driving force is transmitted to the output shaft 3.
そして、開閉体が前記範囲内に位置している間
は、突起22aは第2水平溝45b内にあり、入
力軸2の第2軸部22が第2位置に保持される。 While the opening/closing body is located within the range, the protrusion 22a is within the second horizontal groove 45b, and the second shaft portion 22 of the input shaft 2 is held at the second position.
逆に、開閉体が前記範囲外に移動する際には、
突起22aが第2水平溝45bから傾斜溝45c
内に入り、該傾斜溝45c内を第1水平溝45a
に向つて移動する。 Conversely, when the opening/closing body moves outside the above range,
The protrusion 22a extends from the second horizontal groove 45b to the inclined groove 45c.
the first horizontal groove 45a inside the inclined groove 45c.

engage again. Note that the first speed change gear 42 may mesh with the input side gear 23. In this case, both partners are spur gears.

駆動伝達装置。[Scope of Claims] 1. A drive transmission device that opens and closes an opening/closing body by transmitting the rotation of an input shaft connected to a motor side to an output shaft, comprising
a second shaft portion movable between the position and the second position;
While fixing a small gear and a large gear to the second shaft portion,
The output shaft includes a small gear that meshes with the large gear when the second shaft portion is in the first position, and a large gear that meshes with the small gear when the second shaft portion is in the second position. A cam gear that is fixedly installed and interlocks with the input shaft at a speed different from the rotation of the input shaft is held immovably in the axial direction and loosely fitted to the second shaft portion, and the cam gear is loosely fitted to the second shaft portion. A cam groove is provided on one side of the cam gear, and a protrusion that becomes a cam follower that fits into the cam groove is provided protrudingly on the other side, and the difference in rotational speed between the two shaft parts and the cam gear causes the second shaft part to A drive transmission device characterized by having a transmission mechanism that switches and holds the position or the second position.
