【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、空冷減速機における冷却ファンに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a cooling fan in an air-cooled speed reducer.

。FIG. 2 shows a conventional reduction gear with a cooling fan. A cooling fan 2 attached to the high-speed shaft 1 of the reducer blows cold air onto the gear case 3 to prevent the temperature of the reducer from rising. The speed reducer is connected to the prime mover via a coupling 4, and the high-speed shaft 1 is elongated in order to attach the cooling fan 2. For this reason, not only does the installation area of the reducer increase, but also the high-speed shaft 1
As the number of alignment errors increases, it is necessary to improve machining accuracy. Furthermore, since the shaft end was elongated, the moment load from the coupling 4 increased, and countermeasures such as increasing the size of the bearing supporting the high-speed shaft 1 were required.

の問題点があった。The above-mentioned conventional technology does not take into account the mounting method of the cooling fan 2, and there is a problem in that the installation area of the reduction gear increases. In addition, in order to prevent misalignment of the high-speed shaft 1, the machining accuracy of the high-speed shaft 1 must be improved, and the moment load increases, so there are problems such as increasing the size of the bearing that supports the high-speed shaft 1.
本発明の目的は、高速軸１の寸法、及び、形状を変える
ことなく、冷却ファン２を取付けうる減速機を提供する
ことにある。An object of the present invention is to provide a speed reducer to which a cooling fan 2 can be attached without changing the dimensions and shape of the high-speed shaft 1.
上記目的を達成するために、カップリング外周に冷却フ
ァンを取付け、カップリングと冷却ファンを一体化した
構造としたものである。In order to achieve the above object, a cooling fan is attached to the outer periphery of the coupling, and the coupling and the cooling fan are integrated into a structure.
カップリング外周に冷却ファンを取付けることにより、
高速軸を長く伸す必要がなくなり、冷却ファン不付の減
速機と同じ設置面積で、強制空冷化を実現できる。By installing a cooling fan around the outer circumference of the coupling,
There is no need to extend the high-speed shaft long, and forced air cooling can be achieved with the same installation space as a reducer without a cooling fan.
以下、本発明の一実施例を第１図により説明する。 An embodiment of the present invention will be described below with reference to FIG.
第１図において、１は高速軸、３はギヤケース、４はカ
ップリング、５は冷却ファンの羽根である。In FIG. 1, 1 is a high-speed shaft, 3 is a gear case, 4 is a coupling, and 5 is a cooling fan blade.

できる。本実施例によれば、冷却ファンを取付けるため
高速軸１を伸す必要がなく、冷却ファン不付の減速機と
同じ設置面積で強制空冷化を実現できる。Cold air is sent out from the blades 5 directly attached to the outer periphery of the coupling 4, and the surface temperature of the gear case 3 can be lowered. According to this embodiment, there is no need to extend the high-speed shaft 1 to attach a cooling fan, and forced air cooling can be achieved with the same installation area as a reducer without a cooling fan.
尚、カップリング４の外周に羽根５を、直接、−３＝
取付けるのではなく、第３図に示す様に、リング状のボ
ス６に羽根５を取付け、これをカップリング４の外周に
焼ばめ等の方法で取り付けても同様の効果がある。Note that instead of attaching the blade 5 directly to the outer periphery of the coupling 4, the blade 5 is attached to a ring-shaped boss 6, as shown in FIG. A similar effect can be obtained by attaching by a method such as fitting.
本発明によれば、冷却ファン不付の減速機と同し設置面
積で強制空冷化を実現することができる。According to the present invention, forced air cooling can be realized with the same installation area as a reducer without a cooling fan.
また、高速軸を長く伸す必要がないので、アライメント
誤りを防止するための加工精度の向上や、モーメント荷
重の増大による軸受のサイズアップが不要となる効果も
ある。Furthermore, since there is no need to extend the high-speed shaft long, there is also the effect of improving machining accuracy to prevent alignment errors and eliminating the need to increase the size of the bearing due to an increase in moment load.
さらに、水冷式減速機から空冷式減速機にリプレースす
る場合、原動機や被動機のセツティングを変更すること
なく実現できる。Furthermore, when replacing a water-cooled speed reducer with an air-cooled speed reducer, it can be accomplished without changing the settings of the prime mover or driven machine.
