る。 By the way, in an emergency, a rotating body such as a turbine
stops operation, so it is desirable that the oil supply from head tank b gradually decreases in proportion to the gradual decrease in the rotational speed of rotating body a. However, in the conventional emergency lubricating oil supply system as described above, Since the lubricating oil supply pipe c is connected to the single lubricating oil flow port e in the head tank b, the lubricating oil supplied from this head tank b in an emergency is sent to the above-mentioned lubricating part at almost the same flow rate. There is.

Figures 3 and 4 show an emergency lubricating oil supply device as the first embodiment of the present invention, Figure 3 is a perspective view thereof, and Figure 4 is a perspective view thereof. is a cross-sectional view taken along the - arrow in FIG. 3, and FIG. 5 is a vertical cross-sectional view corresponding to FIG. 4, showing an emergency lubricating oil supply device as a second embodiment of the present invention.
まず、本考案の第１実施例について説明する

ツドタンク２が配設されており、このヘツドタン
ク２と潤滑部とは、潤滑油供給管３によつて接続
されている。 First, the first embodiment of the present invention will be described. As shown in FIGS. 3 and 4, a head tank 2 for storing lubricating oil is disposed above a lubricating part of a bearing (not shown) of a rotating body 1. The head tank 2 and the lubricating section are connected by a lubricating oil supply pipe 3.

It is connected to two oil flow ports 4 and 5 formed on the side surface 2a of the head tank 2 by a plurality of tightening bolts 6, and these oil flow ports 4 and 5 are formed with a level difference from each other. There is.

給管３のフランジ部３ａとヘツドタンク２の側面
２ａとの間に設けられている。 The oil supply system connected to the lower oil flow port 5 is provided with an orifice 7 so as to have a smaller oil supply capacity than the oil supply system connected to the upper oil flow port 4. is provided between the flange portion 3a of the lubricating oil supply pipe 3 and the side surface 2a of the head tank 2.

気流通管を示している。 In addition, in Fig. 4, reference numeral 8 indicates a discharge port, 9 indicates a pipe leading from the upper part of the head tank 2 to the oil reservoir, 10 indicates a tightening bolt, 11 and 12 indicate the lubricating oil level, and 13 indicates an outside air flow pipe. There is.
本考案の非常用潤滑油供給装置は上述のごとく
構成されているので、オーバーフローした潤滑油
は、排出口８より流出して、配管９を通り、図示
しない潤滑油タンクにもどることになり、したが
つて、ヘツドタンク２から潤滑油を供給する場合
には、潤滑油の油面１１は、常に排出口８より下
に保持されることになる。 Since the emergency lubricating oil supply device of the present invention is configured as described above, overflowing lubricating oil flows out from the discharge port 8, passes through the piping 9, and returns to the lubricating oil tank (not shown). Therefore, when lubricating oil is supplied from the head tank 2, the oil level 11 of the lubricating oil is always maintained below the discharge port 8.
そして、回転体１の潤滑部への強制供給が停止
した非常時には、ヘツドタンク２から潤滑油の供
給が行なわれ、その供給初期には、油流通口４，
５の２つの油流通口から、多量の潤滑油が流出さ
れることになる。 In an emergency when the forced supply to the lubricating part of the rotating body 1 is stopped, lubricating oil is supplied from the head tank 2, and at the beginning of the supply, the oil flow port 4,
A large amount of lubricating oil will flow out from the two oil flow ports 5.
なお、ヘツドタンク２からの潤滑油供給の初期
には、回転体１は、まだ慣性力により高速で回転
しているため、多量の潤滑油が必要である。 Note that at the beginning of the supply of lubricating oil from the head tank 2, the rotating body 1 is still rotating at high speed due to inertial force, so a large amount of lubricating oil is required.
そして、油面１１が、油流通口４を通過して、
油面１２（第４図２点鎖線参照）の位置になるま
で、多量の潤滑油が流れる。 Then, the oil level 11 passes through the oil flow port 4,
A large amount of lubricating oil flows until it reaches the oil level 12 (see the two-dot chain line in FIG. 4).
なお、油面１１の位置が油面１２の位置まで下
がるのに要する時間を、５分程度とするように、
油流通口４およびオリフイス７の径が定められ
る。 Note that the time required for the oil level 11 to drop to the oil level 12 is approximately 5 minutes.
The diameters of the oil flow port 4 and the orifice 7 are determined.
油面１１が油面１２の位置にくると、それ以
降、潤滑油は油流通口５だけから流出する。 Once the oil level 11 reaches the oil level 12, lubricating oil flows out only from the oil flow port 5.
そして、油流通口５には、オリフイス７が取付
けられているので、潤滑油供給管３を流れる潤滑
油量は少量となる。 Since the orifice 7 is attached to the oil flow port 5, the amount of lubricating oil flowing through the lubricating oil supply pipe 3 is small.
なお、オリフイス７から流れる潤滑油量は、ヘ
ツドタンク２の底から油面１２までの高さの（1/
２）乗に比例する。 The amount of lubricating oil flowing from the orifice 7 is equal to (1/1/2) the height from the bottom of the head tank 2 to the oil level 12.
2) Proportional to the power.
このようにして、油面１２が下がるに従い、オ
リフイス７から流れ出る潤滑油量は、従来の場合
（第２図参照）に比べて減少することになる。 In this way, as the oil level 12 decreases, the amount of lubricating oil flowing out from the orifice 7 decreases compared to the conventional case (see FIG. 2).
その際、回転体１の回転数は、指数関数的に減
少するので、潤滑油の供給初期以降の潤滑油量
は、少流量でよいことになる。 At this time, since the rotational speed of the rotating body 1 decreases exponentially, the amount of lubricating oil after the initial stage of lubricating oil supply may be small.
なお、潤滑油の供給が、油面１１の位置から始
まつて、その供給が終わるまでの所要時間として
は約１時間程度あれば十分である。 It should be noted that approximately one hour is sufficient for the time required for the supply of lubricating oil to start from the position of the oil level 11 and end the supply.

る。 In a second embodiment of the present invention shown in FIG. 5, a lubricating oil supply pipe 14 connecting the lubricating part of the bearing of the rotating body 1 (see FIG. 3) and the head tank 2 is formed on the side surface 2a of the head tank 2. The lubricant supply pipe 14 is connected to three oil flow ports 15, 16, and 17 having different levels, and the cross-sectional area A of the lubricant oil supply pipe 14 is the sum of the cross-sectional areas of the oil flow ports 15, 16, and 17. However, other configurations are the same as those of the first embodiment described above, and substantially the same effects can be obtained. In FIG. 5, the same reference numerals as in FIGS. 3 and 4 indicate substantially the same parts.

うな効果ないし利点を得ることができる。 As detailed above, according to the emergency lubricating oil supply device of the present invention, there is a lubricating oil storage head tank disposed above the lubricating part, and a lubricating oil supply pipe connecting the head tank and the lubricating part. With a simple structure in which the lubricating oil supply pipe is connected to a plurality of oil flow ports in the head tank and the oil flow ports have different levels from each other, the following effects or advantages can be obtained. I can do it.
(1) 多量の潤滑油を必要とする初期には、複数の
油流通口から多量の潤滑油を潤滑部に供給し、
少量の潤滑油で足りるようになると、個数の減
少した油流通口より少量の潤滑油を流して、潤
滑油の供給時間を長くすることができる。(1) In the initial stage when a large amount of lubricating oil is required, a large amount of lubricating oil is supplied to the lubricating part from multiple oil flow ports.
When a small amount of lubricating oil becomes sufficient, the lubricating oil supply time can be extended by flowing a small amount of lubricating oil through the reduced number of oil flow ports.
(2) 回転体の潤滑部に供給される潤滑油の量が全
体として少なくなるので、ヘツドタンクを小型
化することができ、ヘツドタンクの据付けスペ
ースも少なくてすむ利点がある。(2) Since the amount of lubricating oil supplied to the lubricating portion of the rotating body is reduced overall, the head tank can be downsized, and there is an advantage that the installation space for the head tank can be reduced.
(3) 潤滑部への給油を長時間行なえるようになる
ので、軸受部などにおける焼き付けを防止する
ことができる。(3) Since lubricating parts can be supplied with oil for a long time, seizing in bearing parts etc. can be prevented.
