Claims20
An oil seal structure comprising:
- a rotating shaft;
- a bearing configured to rotatably support the rotating shaft;
- a lower housing portion comprising a first bearing accommodating groove in which the bearing is provided;
- an upper housing portion comprising a second bearing accommodating groove in which the bearing is provided;
- an assembly surface seal member inserted into a first assembly surface seal groove formed in a surface, from among surfaces of the lower housing portion, facing the upper housing portion;
- and
- an oil seal member provided in a first seal groove formed in the lower housing portion and a second seal groove formed in the upper housing portion, and comprising a flange portion,
- wherein a lower oil receiving portion is formed in the lower housing portion to be located between the first bearing accommodating groove and the first seal groove, and
- wherein a first passage groove, which is directly connected to the first assembly surface seal groove, is formed in the first seal groove and an oil passage is formed between a bottom surface of the first passage groove and the flange portion.
A compressing apparatus comprising:
- a rotating shaft;
- at least one bearing configured to rotatably support the rotating shaft;
- a lower housing portion comprising a first bearing accommodating groove in which the bearing is provided;
- an upper housing portion comprising a second bearing accommodating groove in which the bearing is provided;
- an assembly surface seal member inserted into a first assembly surface seal groove formed in a surface, from among surfaces of the lower housing portion, facing the upper housing portion;
- at least one oil seal member provided in a first seal groove formed in the lower housing portion and a second seal groove formed in the upper housing portion and comprising a flange portion;
- and
- at least one impeller driven by receiving power from the rotating shaft,
- wherein a lower oil receiving portion is formed in the lower housing portion to be located between the first bearing accommodating groove and the first seal groove, and
- wherein a first passage groove, which is directly connected to the first assembly surface seal groove, is formed in the first seal groove and an oil passage is formed between a bottom surface of the first passage groove and the flange portion.
