の間には、厚さｈのクリアランスができるため、
両者の間には接触はおこらない。 Next, the operation of this device will be explained: Testing machines are prepared as many as the number of tires of the automobile to be tested, and each tire is set so as to ride on the running belt 02. The running belt 02 is stretched between two rotating drums 08, and runs over the pallet 01 as the drums 08 rotate. The load of the tire is supported by the pallet 01 via the running belt 02. The load capacity of pallet 01 is
Pressure p of the supply water sent from 2 to pocket 011
This occurs due to the land portion 013 and running belt 02
There is a clearance of thickness h between the
There is no contact between the two.
ポケツト０１１に供給された水は、厚さｈのク

きい。さらに、水回収溝０１４の外側へ漏れる水
量を減少させるため、水切りシール０３、バネ０
４は水回収溝０１４の外側にも設けられている。 The water supplied to the pocket 011 flows out from the clearance of thickness h, but since the running belt 02 moves at high speed, the running belt 02 does not reach the pallet 0.
In the part that breaks out from 1, due to the quest flow,
A large amount of water flows out from the pocket 011 in the belt traveling direction. This outflow water is blocked by a drainage seal 03 provided on the land portion 013. Since the draining seal 03 is pressed against the running belt 02 from the back side by a spring 04, it can follow the fluttering of the running belt 02 and is always in contact, so it is highly effective in blocking outflow water. Furthermore, in order to reduce the amount of water leaking to the outside of the water collection groove 014, a drain seal 03 and a spring 0
4 is also provided outside the water recovery groove 014.
また、パレツト０１外へ出た流出水は、スクレ
ーパ０６、フエルトシール０７によりシールされ
る。 Further, the water flowing out of the pallet 01 is sealed by a scraper 06 and a felt seal 07.
水切りシール０３は、高速で走行する走行ベル
ト０２と接触し摺動しているため、摩耗が激し
く、背面からバネ０４で走行ベルト０２におさえ
つけられてはいるものの、そのシール作用は時間
とともに徐々に低下し、流出水量は増加する。
Since the draining seal 03 is in contact with and sliding on the running belt 02 running at high speed, it is subject to severe wear, and although it is held down from the back by a spring 04 to the running belt 02, its sealing action gradually loses its sealing effect over time. The amount of runoff water increases.
従つて供給水量を増加させる必要があり、ポン
プ出力の増加が必要であるため、コスト増大が避
けられない。 Therefore, it is necessary to increase the amount of water supplied, and the pump output must also be increased, so an increase in cost is unavoidable.
また、摺動部分では、発熱による温度上昇の問
題、動力損失の問題なども発生する。 In addition, sliding parts also have problems such as temperature rise due to heat generation and power loss.
水切りシールと走行ベルトが接触し、摺動する

シールとする。
In order to solve various problems caused by contact and sliding between the drain seal and the running belt, the conventional type of drain seal was abolished and the outflow water was sealed by supplying high-pressure buffer gas, making it a non-contact seal. shall be.
走行ベルトがパレツトから抜け出る部分におい

ことができる。
At the portion where the running belt exits the pallet, the buffer gas prevents the supply water in the pocket from flowing out. Since there is a non-contact seal between the lower surface of the running belt and the land portion, it is possible to maintain a constant gap between the two without causing wear.

In FIG. 1, a pallet 1 is provided with a land portion 13 provided with several divided pockets 11, and a water recovery groove 14 around the land portion 13. A water supply hole 12 is provided in the pocket 11, and water is supplied from a pump (not shown). Land part 13
1 creates a water film, and a water collection groove 14 provided along the outer periphery of the land portion 13 forms a water film.
A labyrinth seal 15 is provided in a land portion 13 between a pocket 11 and a water recovery groove 14 where the running belt 2 exits and collects water flowing out from the belt.
２は走行ベルトで、パレツト１のランド部１３
と厚さｈの水膜で分離された状態で走行する。 2 is a running belt, which is attached to the land portion 13 of pallet 1.
It runs in a state where it is separated by a water film of thickness h.

いない供給源より送られたものである。 The outflow water is first squeezed by a labyrinth seal 15 provided in the land portion 13 between the pocket 11 and the water recovery groove 14. Furthermore, the outflow water is blocked by high-pressure buffer gas supplied from the buffer gas supply hole 5 provided in the land portion 13. Note that this buffer gas was sent from a source not shown in the figure.
さらに、水回収溝１４の外側へ漏れ出る水量を
防ぐため、バツフアガス供給孔５は、水回収溝１
４の外側にも備えられている。 Furthermore, in order to prevent the amount of water leaking to the outside of the water recovery groove 14, the buffer gas supply hole 5 is connected to the water recovery groove 14.
It is also provided on the outside of 4.
なお、本実施例は、作用流体が水の場合につい
てのものであるが、作用流体が油の場合について
