この発明は、ギヤを介して回転力を伝達する動力伝達装
置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a power transmission device that transmits rotational force through gears.
従来の技術
従来、例えばプラテンに回転力を伝達するために、第４
図に示すような動力伝達装置が存する。2. Description of the Related Art Conventionally, for example, in order to transmit rotational force to a platen, a fourth
There is a power transmission device as shown in the figure.

たものである。This is a pair of transmission gears 52 and 53 that mesh with the gear 51.
is fixed to a shaft portion 56 of a platen 55 by a pin 54, and the shaft portion 56 is biased by a wave washer 58 to eliminate play in the thrust direction of the shaft portion 56 with respect to a bearing 57.
一対の伝達ギヤ５２．５３をギヤ５１に噛合させる理由
はこの噛合部分のバックラッシュによる遊びを除去する
ためである。すなわち、第５図に示すように、伝達ギヤ
５２．５３をスプリング５９により相反する回転方向へ
付勢し、伝達ギヤ５２．５３の外周の歯をずらした状態
でギヤ５１に噛合させるものである。The reason why the pair of transmission gears 52 and 53 are meshed with the gear 51 is to eliminate play due to backlash in the meshing portion. That is, as shown in FIG. 5, the transmission gears 52, 53 are biased in opposite rotational directions by the spring 59, and the transmission gears 52, 53 are meshed with the gear 51 with the teeth on the outer periphery being shifted. .

ギヤ５２，５３をギヤ５１に噛合する時に、伝達ギヤ５
２，５３がスプリング５９の力により戻り組立し難い。Problems to be Solved by the Invention However, since the transmission gears 52, 53 must be formed with an opening 6o for accommodating the spring 59, the transmission gears 52, 53 are easily deformed during molding, resulting in poor dimensional accuracy. Also, the transmission gear 5
2. When the transmission gears 52 and 53 are engaged with the gear 51 while maintaining the state in which the transmission gear 53 is rotated in the opposite direction, the transmission gear 5
2 and 53 return due to the force of the spring 59, making it difficult to assemble.
問題点を解決するための手段

る。Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 3. Bearings 2 are held by opposing side plates 1, and a shaft portion 4 of a platen 3 is rotatably supported by these bearings 2. A motor (not shown) is mounted on the shaft 5 parallel to the platen 3.
A gear 6 driven by is rotatably fitted therein. A pair of transmission gears 7.8 meshed with this gear 6 are connected to the platen 3.
It is fitted into the shaft portion 4 of. One transmission gear 7 has pin 9
The transmission gear 8 is fixed to the shaft portion 4 and rotates integrally with the platen 3, and the other transmission gear 8 is urged toward the transmission gear 7 by a wave washer 10 mounted between the bearing 2 and the transmission gear 8. Furthermore, these transmission gears 7.8 have the same diameter and the same number of outer peripheral teeth 11, 12, and a plurality of side teeth 13, 14 that mesh with each other are formed at equal intervals on the side surfaces.

゜１４の噛合深さが最大で、外周歯１１．１２の中心１
１ａ、１２ａのずれ量Ｃは最大である。FIG. 3 is an enlarged development of a part of the outer periphery of the transmission gears 2 and 8. Although the center 12a of the outer tooth 12 of one transmission gear 8 and the center 14a of the side tooth 14 coincide with each other, The center 11a of the outer tooth 11 of the other transmission gear 7 and the center 13a of the side tooth 13 are offset. Therefore, Fig. 3 (a
), when the transmission gear 8 is moved toward the transmission gear 7 by the urging force of the wave washer 10, the side teeth 13
The engagement depth of ゜14 is the maximum, and the center 1 of the outer teeth 11 and 12
The amount of deviation C between 1a and 12a is the maximum.

８が軸方向へ摺動し、ギヤ６と伝達ギヤ７．８との間の
遊びが除去され、動力伝達が正確になされる。In such a configuration, when the transmission gear 7.8 and the gear 6 are meshed, the outer peripheral teeth 11, 1.2 receive rotational pressure from the gear 6, so the transmission gear 8 resists the pressure of the wave washer 10. and separates from the transmission gear 7. Assuming that the backlash between the transmission gear 7.8 and the gear 6 is zero, the distance by which the transmission gear 8 separates from the transmission gear 7 is maximum, and as shown in FIG. 12 centers 11a and 12a coincide. Therefore, transmission gear 7
．． The transmission gear 8 slides in the axial direction in response to the backlash between the gear 8 and the gear 6, and play between the gear 6 and the transmission gear 7.8 is eliminated, and power transmission is performed accurately.

寸法精度を高めることができる。In this manner, the wave washer 10 biases the transmission gear 8, but at the same time biases the platen 3 in the axial direction, thereby eliminating play in the axial direction of the platen 3. This also makes it possible to reduce the number of parts. Moreover, it is easy to fit the wave washer 10 to the shaft portion 4,
The transmission gear 7.degree. 8 can also be meshed with the gear 6 while being biased in the axial direction, thus simplifying the assembly work. Further, since the transmission gear 7.8 does not require an opening 60 for accommodating the spring 59 unlike the conventional example, the shape is simple, deformation during molding can be prevented, and dimensional accuracy can be improved.
