廃棄しなければならず損害が大きい。(Problems to be solved by the invention) In the above-mentioned prior art device, the bevel gear portion f,
It is necessary to lubricate gears g, and lubricating oil is stored in a box-shaped revolving shaft d that supports these gears. Although the support portion of the rotating screw shaft b is sealed by a rotary shaft seal, there is a risk that lubricating oil may leak from there and the material being processed in the container 1 may be contaminated with oil. This risk becomes even greater when the inside of the container is evacuated. Once a material is contaminated with oil, it is difficult to restore it to its original state, and in most cases it must be discarded, resulting in significant damage.
潤滑油の代りにグリースを使用したものもある

できなくなる欠点が生ずる。 Some bevel gears use grease instead of lubricating oil, but this reduces the lifespan of the bevel gear.
As an improvement, it is possible to transmit the rotational force by a belt transmission device j as shown in Fig. 3, but this would make the container higher than the conventional technology shown in Fig. 4, and would increase the dead space inside and outside the container.
Since the center line of d' is not perpendicular to the center line of d, a disadvantage occurs in that it is not possible to install a thermometer or spray piping through the center of the drive unit.
