この考案は回転速度の異なる無端ベルトラ同時に緊張で
きるようにした主として内燃機関に用いるベルトの緊張
装置に関する。[Detailed Description of the Invention] This invention relates to a belt tensioning device mainly used in internal combustion engines, which is capable of simultaneously tensioning endless belts having different rotational speeds.
従来内燃機関には発電機や冷却ファン及び水ポンプなど
を駆動する手段として■ベルトなどの無端ベルトを多く
採用している。Conventional internal combustion engines often use endless belts such as ■ belts as a means of driving generators, cooling fans, water pumps, etc.
しかし冷却ファンや発電機と水ポンプとでは回転速度が
異なるため別の無端ベルトで駆動する必要がある。However, since the cooling fan or generator and water pump have different rotational speeds, they must be driven by separate endless belts.
このため従来では回転速度の異なるベルト毎にベルトの
緊張装置を設ける必要があり、構造が複雑となる欠点が
あった。For this reason, in the past, it was necessary to provide a belt tensioning device for each belt having a different rotational speed, which resulted in a disadvantage that the structure was complicated.
この考案はかかる欠点を改善する目的でなされたもので
、回転速度の異なる無端ベルトを１個所で同時に緊張で
きるようにしたベルトの緊張装置を提供して、個々のベ
ルトに緊張装置を設ける無駄をなくしたものである。This invention was made for the purpose of improving such drawbacks, and it provides a belt tensioning device that can tension endless belts with different rotational speeds at the same time at one location, thereby eliminating the waste of providing tensioning devices for each individual belt. It's something I lost.
以下この考案を図示の一実施例について詳述する。This invention will be described in detail below with reference to an illustrated embodiment.

移動可能に固定されている。In the figure, 1 is an auxiliary device such as a generator, with one side of the bracket 1a being pivotally supported by a pin 2 on a part of the engine (not shown), and the other side of the bracket 1a is a groove 3a of an adjustment plate 3 whose one end is fixed to the engine 1. It is movably fixed therein by a fixing member 4.

っている。An endless belt 11 wound around the pulley 9 provided on the drive shaft 8 and the boot Oa of the cooling fan 10 is engaged with one pulley 5, and the cooling fan 10 and the auxiliary equipment 1 are operated by this endless belt 11. In addition, the idler pulley T includes a pulley 9 of the drive shaft 8.
A winding endless belt 13 is engaged with the boops 1) 12a provided on the water pump 12 and the water pump 12, respectively, and the water pump 12 is rotated by the endless belt 13.

に緊張できるようになる。Since this invention has been described in detail above, 80 rotations of the drive shaft are connected to the cooling fan 10, the auxiliary equipment 1 such as the generator, and the water pump 12 by means of the endless belt 11° 13 with different rotational speeds.
If you want to tension the endless bell) 11.13, rotate the auxiliary machine 1 in the direction of arrow a using the pin 2 as a fulcrum, and when the specified tension is reached. It is sufficient to fix it to the adjustment plate 3 using the fixing tool 4, and both endless belts 11 and 13 can be tensioned at one place at the same time.
これによって個個の無端ベルＨ１，１３に緊張装置を設
