Description

【０００１】
【発明の属する技術分野】
本発明は、食品製造装置の撹拌軸など特に縦型主軸を油潤するにあたって、潤滑油の滲み出し漏洩を防止し得る撹拌装置の主軸のシール構造に関する。
【０００２】
【従来の技術】
一般に、撹拌装置の主軸部には、高速回転する主軸を支承する軸受装置が配設され、良好な高速回転性を維持するために軸受装置には種々の潤滑が施されている。
【０００３】
しかし、主軸の高速回転時の発熱を避けることはできず、こうした軸受装置の発熱を冷却すると共に低摩擦化を図るためには、軸受装置に冷却効果の優れた潤滑油を供給することが望まれる。
【０００４】
しかし、縦型主軸の場合には、軸受装置に潤滑油を直接供給すると、主軸とハウジングとの隙間から潤滑油が漏洩し、撹拌装置内へ落下して、食品等に潤滑油が混入してしまうという欠点がある。
【０００５】
従って、主軸の軸受装置には、グリースを施し、主軸のハウジング内に軸受に近接した通路を設け、該通路に冷却用の油を流すことにより間接的に軸受を冷却することが行われていた。
【０００６】
しかし、近年の主軸の高速化に伴い、上述の間接的な冷却方式では軸受装置を十分に冷却することは困難であり、主軸部の温度上昇を招き、軸受装置の寿命の低下をきたすという欠点があった。
【０００７】
従来、シール部材のオイル漏れ対策として、２重シール構造を採用することも提案されている。この構造では、寿命は長いと思われるが、シール部材の磨耗によりオイルが漏れ出してからの交換となるため、その時、生産していた食品は不良となるおそれがある。さらに、高速回転の軸シールの場合、シール部材の発熱によりシール部材が破損する場合がある。
【０００８】
また、高速回転の軸シールの場合は発熱を防止するため、シール部材材と主軸との当たり代（接触面積）を小さく設定することが考えられる。しかし、このような構造にすると、シール性能を損なうという欠点があった。
【０００９】
【発明が解決しようとする課題】
本発明は上記従来の欠点を解決するものであり、その目的とするところは、高速回転の軸シールの場合でも、シール部材の発熱によりシール部材が破損するおそれのない撹拌装置の主軸のシール構造を提供することにある。
【００１０】
本発明の他の目的は、油漏れが事前に発見できる撹拌装置の主軸のシール構造を提供することにある。
【００１１】
【課題を解決するための手段】
本発明の撹拌装置の主軸のシール構造は、主軸ハウジング内に鉛直方向に長く配置された主軸が軸受を介して回転可能に保持され、該軸受の下方位置において、該主軸ハウジングと主軸との間にシール手段が設けられた撹拌装置の主軸のシール構造であって、該シール手段は、主軸側に向けて開口する開口部を有する断面略Ｃ字状のシール部材を有し、該シール部材の遊端部が主軸の外面に近接してシール部材と主軸外面との間に空間部が形成され、該空間部内へ潤滑用および／または冷却用の媒体を供給し得る供給手段が設けられており、そのことにより上記目的が達成される。
【００１２】
一つの実施形態では、前記シール部材は外側片と、該外側片の両端部から主軸側へ延設された上片および下片を有し、該上片から主軸外面に沿って下方へ延設された第１内側片と、該下片から主軸外面に沿って上方へ延設された第２内側片と、を有し、該第１および第２内側片が該主軸外面に近接し、該外側片に前記空間部内へ媒体供給用の通孔が形成されている。
【００１３】
一つの実施形態では、前記潤滑用および／または冷却用の媒体が潤滑油の粒子を含む圧縮空気であり、該媒体の供給手段がハウジングに設けられた通路を有し、該通路内を通る圧縮空気が前記主軸とシール部材との間の空間部内に入る。
【００１４】
一つの実施形態では、前記シール部材に媒体を排出する出口用通孔が形成され、主軸ハウジングに設けられた通路を通ってシール部材内の媒体が排出される。
【００１５】
一つの実施形態では、前記撹拌装置は食品製造装置における撹拌装置であり、前記主軸ハウジングの通路出口に圧縮空気を通す透明チューブが接続されている。
【００１６】
以下、本発明の作用を説明する。
【００１７】
断面略Ｃ字形のシール部材の遊端部が主軸の外面に近接してシール部材と主軸外面との間に空間部が形成され、該空間部内へ潤滑用および／または冷却用の媒体を供給し得る供給手段が設けられていることにより、シール部材の空間部内へ、油粒子の含んだ圧縮エアーを通過させることができ、このようにシール部での潤滑となるため、グリスを用いないドライな環境でも磨耗を防止できる。
【００１８】
特に、シール部材に設けた媒体排出用の出口用通孔から、透明チューブを通って潤滑油を含む圧縮空気が通るようにすると、透明チューブを介して油漏れが事前に発見できる。
【００１９】
また、潤滑用および／または冷却用の媒体として、圧縮エアー、水、油などを通過させることにより、シール部の発熱を防止できる。
【００２０】

【００２８】
シール部材４の外側片４１に通孔４７が形成され、上記主軸ハウジング２および軸受押さえ２１に形成された通路２５と連通している。通孔４７，４８はシール部材４の主軸１を挟んで対向する位置、つまり、１８０°ずれた位置にそれぞれ２箇所形成されている。主軸ハウジング２に形成された通路２５の入り口に圧縮空気ノズル２６が接続される。この圧縮空気は、霧状の油を含有するのがよく、また圧縮空気の代わりに、水、油を供給してもよい。
【００２９】
この通路２５と対向する位置において、主軸ハウジング２および軸受押さえに通路２７が形成され、この通路２７は、上記シール部材４に形成された第２の通孔４８と連通している。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a seal structure of a main shaft of a stirrer which can prevent leakage and leakage of lubricating oil when lubricating a vertical main shaft such as a stir shaft of a food manufacturing apparatus.

Conventionally, it has been proposed to adopt a double seal structure as a measure against oil leakage of a seal member. In this structure, the service life is considered to be long, but since the oil leaks out due to the wear of the seal member and is replaced, the food produced at that time may be defective. Further, in the case of a high-speed rotating shaft seal, the heat generated by the seal member may damage the seal member.
[0008]
In the case of a high-speed rotating shaft seal, it is conceivable to set a small contact area (contact area) between the seal member and the main shaft in order to prevent heat generation. However, such a structure has a disadvantage that the sealing performance is impaired.

A first inner piece, and a second inner piece extending upward from the lower piece along the outer surface of the main shaft, wherein the first and second inner pieces are close to the outer surface of the main shaft, A through-hole for supplying a medium is formed in the outer piece into the space.
[0013]
In one embodiment, the lubricating and / or cooling medium is compressed air containing particles of a lubricating oil, and the medium supply means has a passage provided in the housing, and the compression means passes through the passage. Air enters the space between the main shaft and the sealing member.
[0014]
In one embodiment, an outlet through-hole for discharging the medium is formed in the seal member, and the medium in the seal member is discharged through a passage provided in the spindle housing.
[0015]
In one embodiment, the stirring device is a stirring device in a food manufacturing device, and a transparent tube for passing compressed air is connected to a passage outlet of the spindle housing.
[0016]
Hereinafter, the operation of the present invention will be described.
[0017]
