超大型舶用平行軸歯車減速機・遊星歯車減速機

超大型舶用平行軸歯車減速機・遊星歯車減速機は中超大型舶用平行軸歯車減速機・遊星歯車減速機の用途

小型舶用減速機で培われた経験と技術を生かし設計客船、フェリー、RO/RO船等製作された減速機です。最新鋭の工場、グリーソンファウターP2400G等の新型歯車研削盤で加工され超大型舶用平行歯車減速機の特長た高精度歯車を使用しており、高い信頼性と静粛な運１．静粛な高精度歯車使用転をお約束します。

新規導入されたグリーソンファウター歯車研削盤で高精度平行軸歯車減速機で約14700kW(20000PS)、遊に歯車を加工します。

星歯車減速機で22000kW(30000PS)まで製作可能です。平行軸歯車減速機では横異芯形・縦異芯形等ご希望の軸配置に対応可能です。
また、ご希望により燃費の良い主機関から発電機を駆２．浸炭歯車使用により軽量コンパクト
全ての歯車は浸炭焼き入れを施した歯面硬化歯車を採用しており、調質ギア・高周波焼き入れギアに比べ軽量コンパクトになります。
３．シンプルでメンテナンスの容易な構造

動する発電機駆動装置（PTO）、主機関停止時に補助部品点数の少ないシンプルな構造ですのでメンテナンスコ動力により自力航行することの出来る非常航行駆動

ストを削減することが出来ます。

装置（PTI）を装備した減速機の製作も可能です。

４．特殊仕様にも対応可能
１）油圧クラッチ内蔵型減速機２）２機１軸形減速機

Parallel shaft type reduction gear and epicycle
reduction gear for large size vessels have been
designed and built based on our technologicalexpertise on manufacturing reduction gears forsmall and medium size vessels. High reliability
and silent operation are the result of highprecision gears manufactured with the latest gear
grinding machine, Model P2400G from GleasonPfauter, at the most advanced gear manufacturing
plant.
Reduction gears for the parallel shaft type and forthe epicycle type can be built up to a capacity of14700 kW (20000 PS) and up to 22000 kW (30000PS) respectively. Shaft offset can be designed in
the horizontal or in the vertical position for theparallel shaft type reduction gears.
In response to customer needs, it is possible toapply a generator drive mechanism (PTO) to drive
the generator from the low-fuel-consumption main
engine, or an emergency navigation drive system(PTI) possible of navigating under main engine
failure.

•Features of Parallel Shaft type Reduction Gears forLarge Size Vessels
1. Application of high precision gears operated quietly
Gears machined with the latest Gleason-Pfauter gear
grinding machine are made to JIS Class 0 accuracy.
2. Light and compact by using carburized and case hardened
gears Carburized and case hardened gears are applied to
all gears. This method makes the gears more compact andlighter than hardened or induction hardened gears.
3. Simple and Low Maintenance Cost Structure
Maintenance cost can be reduced due to the simple gear
mechanism.
4. Application of Custom-made Specifications
1) Reduction gears with integrated hydraulic clutch.
2) Compound type reduction gears.
3) Integration of power take-off mechanism (PTO) or
emergency navigation system (PTI).
4) Mounting of lubrication system.

超大型舶用遊星歯車減速機の特長
１．静粛な高精度研削インターナルギア使用
グリーソンファウター歯車研削盤で高精度に歯車を加工します。
２．独特の等配機構
プラネットギア支持軸を片持ち梁とした独特のフレキシブルピン方式を採用していますので、抜群の等配効果が得られます。

３．軽量コンパクト
遊星歯車機構で、かつ独特の等配機構を採用しています
ので、平行歯車減速機に比べては勿論、他の遊星歯車減速機と比べても軽量コンパクトです。平行歯車減速機に比べ容積・投影面積とも約７０％となります。
４．入出力軸が同心入出力軸が同心上にありかつ３項の特長と合わせ据付専有面積が驚くほど小さくなります。
５．特殊仕様にも対応可能
１）油圧クラッチ内蔵型減速機
２）動力取り出し装置(ＰＴＯ)、非常航行駆動装置(ＰＴＩ)の組み込み
３）潤滑装置の取り付け•Features of Epicycle Reduction Gear forLarge Size Vessels
1. Application of high precision ground internal gear
operated quietly
Gears including internal gears are of accuracy exceeding
JIS Class 0, machined with Gleason-Pfauter gear grinding
machine.
2. Original load distribution mechanism
Excellent load distribution effect can be attained due toour flexible pin method where the planet gears aresupported as cantilever beam shafts.
3. Lightweight and compact
Our epicycle reduction gears are lightweight and compact,
超大型舶用減速機納入実績

compared with not only our parallel shaft type reduction
gears but also other epicycle reduction gears, thanks toour epicycle gear mechanism with its unique load
distribution mechanism.
4. Co-axial shaft
Remarkable reduction of installation space can beattained due to the co-axial shaft in addition to the featureexplained in above item 3.
5. Application of Custom-made Specifications
1) Reduction gears with integrated hydraulic clutch.
2) Integration of power drive mechanism (PTO) oremergency navigation system (PTI).
3) Mounting of lubrication system
