（産業上の利用分野）
本発明は、保合面に歯型を設けたコグベルトを用いる伝
動装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a transmission device using a cog belt having tooth patterns on its retaining surface.
（従来の技術）
平行に配置された２軸間で高速回転を確実に伝達する手
段としては、ギヤ又はチェーンによるものが一般であり
（例えば実開昭５２−１［１９２５０）、エンジンの弁
開閉用などにはコグベルトが用いられている。(Prior art) Gears or chains are generally used as means for reliably transmitting high-speed rotation between two shafts arranged in parallel (for example, Utility Model Application Publication No. 52-1 [19250]), which is used to open and close engine valves. Cog belts are used for various purposes.

性の高い伝動装置を得ることを課題とする。(Problems to be Solved by the Invention) Among the conventional devices described above, those that use gears have the disadvantage that the distance between the axes changes when the temperature of the device rises, making it easy to generate hammering sounds in the occlusion and surfaces. This type uses a slipper-type tensioner, which causes a large amount of friction loss. An object of the present invention is to overcome these drawbacks of gears and chains and to obtain a transmission device that is quiet, reliable, has little power loss, and is highly reliable.

Wrap the cog belt around the cog pulleys fixed to both rotating shafts,
The top of the cog belt is on the loose side and a tension roller is pressed against the top surface.

イルパン９が取付けられている。(Example) Hereinafter, the present invention will be described in detail with reference to the drawings. This embodiment is an example in which the primary reduction gear of an engine is implemented, and the engine 1 includes a crank case 2, a cylinder block 3.4
, a cylinder head 5.6, a crankshaft 7 and a main shaft 8 are supported on the crankcase 2, and an oil pan 9 is attached to the lower surface of the crankcase 2.

、該緩み側にテンションプーリ１４が圧接される。A driving cog pulley 10 is fixed to the crankshaft 7, and a double-acting cog pulley 12, which is integrated with the outer member of the main clutch 11, is rotatably supported on the main shaft 8.
．． A cog belt 13 is wound around 12 and rotates in the direction of arrow A. Therefore, the lower portion of the cog belt 13 becomes the tension side, and the upper portion becomes the slack side, and the tension pulley 14 is pressed against the slack side.

からコグ部に供給させている。The tension pulley 14 is attached via a ball bearing 17 to one end of a lever 18 which is swingably supported by a pin 15 attached to the crankcase 2, and a tension spring is attached to the other end of the lever 16. 18 is locked, and its tension presses the tension pulley 14 against the upper surface of the cog belt 13. In the figure, 19 is lubricating oil, 20 is its oil level, 2
Reference numeral 1.22 denotes an injection nozzle provided on the side where the cog engages, and the lubricating oil branched from the lubricating oil path that supplies each part is supplied from the injection nozzle to the cog part.

ることがない。When the engine 1 operates and the crankshaft 7 rotates, the driven cog pulley 12 is rotated by the cog belt 13, and torque is transmitted to the output side via the main clutch 11 and a gear train not shown. On the loose side, it contacts the tension pulley 14, but since this contact is a rolling contact, there is no friction loss, and therefore no heat generation occurs due to friction. Furthermore, since the tension pulley 14 is located far from the oil level 20, even if the oil level 20 fluctuates, the rotation of the tension pulley 14 does not stir the lubricating oil 19, so the oil temperature does not rise. .
