【考案の詳細な説明】
本考案は、冷却装置の付いた分割形のねじり振動を回避
するゴムダンパに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a split-type rubber damper with a cooling device that avoids torsional vibration.
一般にゴムダンパは、軸にねじり振動が生じるとこの振
動エネルギを摩擦で熱に変え、振動を減少ないし回避す
るもので、このため発生する熱によってゴムが劣化しや
すい。In general, rubber dampers reduce or avoid vibration by converting the vibration energy into heat through friction when torsional vibration occurs on the shaft, and the rubber tends to deteriorate due to the generated heat.
殊に、ゴムダンパを使用する場所は風通しのよい所とは
限らず、例えば舶用の機関室などに使用されると、時な
らず防振の効用が失われる。In particular, rubber dampers are not always used in places with good ventilation, and if they are used, for example, in a ship's engine room, their anti-vibration effect is often lost.
また、現今振動に対し厳しい要求がなされ、各種ダンパ
が必要となり、そのため、ダンパの種類が多く、取扱に
不便である。In addition, there are now strict demands on vibrations, and various dampers are required.Therefore, there are many types of dampers, making them inconvenient to handle.
本考案は以上の事情に鑑み案出されたもので、第１図は
縦断面図で、第２図は分解図であるが、１は大径のダン
パで、環状の慣性体４と有孔円板７との間に環状のゴム
５を挟着している。The present invention was devised in view of the above circumstances. Fig. 1 is a longitudinal cross-sectional view, and Fig. 2 is an exploded view. 1 is a large-diameter damper, an annular inertial body 4 and a perforated damper. An annular rubber 5 is sandwiched between the disc 7 and the disc 7.
２は小径のダンパで、環状の慣性体８と有孔円板９との
間に環状のゴム１０を挟着している。Reference numeral 2 denotes a small-diameter damper, in which an annular rubber 10 is sandwiched between an annular inertial body 8 and a perforated disc 9.
そしてこれらダンパ１，２の間に放射状の羽根１１を植
設した環状の冷却ファン３を挾持し、各有孔円板７，９
をボルト１２で締付している。An annular cooling fan 3 having radial blades 11 is sandwiched between these dampers 1 and 2, and each of the perforated discs 7 and 9
is tightened with bolt 12.
そしてボルト１２の位置を規格化しておけば、各種の慣
性力及び径の異なるダンパをボルト１２でもって組合わ
せすることができる。If the positions of the bolts 12 are standardized, dampers with various inertia forces and diameters can be combined using the bolts 12.

２のゴム５，１０は冷却され、劣化促進を防止する。Therefore, as shown by the arrow in FIG.
The rubbers 5 and 10 of No. 2 are cooled to prevent accelerated deterioration.
以上要するに本考案は、慣性体と板とで挟着したゴムか
らなる２個のゴムダンパでもって、羽根を有する冷却フ
ァンを着脱自在に挾持したゴムダンパであるから、次の
効果を有する。In summary, the present invention has the following effects because it is a rubber damper in which a cooling fan having blades is detachably held between two rubber dampers made of rubber sandwiched between an inertial body and a plate.
■ ２個のゴムダンパを着脱自在にしたから組合せを変
えることにより、多用されるゴムダンパの種類を減らし
、部品の共通化を計り、量産による製造コストの低置が
できる。■ Since the two rubber dampers are detachable, the combination can be changed to reduce the number of commonly used rubber dampers, standardize parts, and lower manufacturing costs through mass production.
■ 中間に冷却ファンを介在させたから、ゴムの信頼性
、寿命が増大し、防振ゴムの劣化を防止する。■ The intervening cooling fan increases the reliability and lifespan of the rubber, and prevents deterioration of the anti-vibration rubber.
