Problems solved by technology

However, in the step of joining the first part and the second part, if the first part and the second part are joined with the seal member exposed to the outside of the seal groove, or if there is a defect in the seal member If the position is not correct, there will be a disadvantage that a gap will be generated in the bonding surfaces of the parts, and the fluid will leak from the sealing member to the outside air side.
[0004] However, with the conventional seal structure, the distance between the seal groove and the outside of the first and second parts is long, and it takes a long time for the fluid to reach the outside of the parts from the seal groove.
Therefore, it is difficult to detect the disadvantages mentioned in the previous paragraph during the inspection process at the time of shipment with limited time

Embodiment Construction

[0043] Below, refer to Figure 1 to Figure 6 , the first embodiment of the present invention will be described.

[0044] Such as Figure 1 ~ Figure 4 As shown, the gear pump of this embodiment mainly includes: a casing 1, which is formed by joining a main body 11 and a cover body 12. The main body 11 is the first part having a gear storage chamber 11a inside, and the cover body 12 is The second part that closes the gear storage chamber 11a of the main body 11; the pair of external gears, that is, the driving gear 2 and the driven gear 3, are stored and held in the gear storage chamber 11a of the housing 1 and mesh with each other; A bush 7 is disposed between the shaft holes 11x, 11y, 12x, 12y for respectively accommodating the drive shaft 4 and the driven shaft 5 and the shafts 4, 5, and the drive shaft 4 and the driven shaft 5 supports the driving gear 2 and the driven gear 3; and a gasket 8 is a sealing member located between the main body 11 and the cover 12.

Abstract

This seal structure for a member uses an annular seal structure in which a first component and a second component are provided between mutually opposing bonding surfaces, wherein the seal structure for a member uses a gasket (8) which is an annular seal member in which a body (11) as the first component and a cover (12) as the second component are provided between mutually opposing bonding surfaces (11f, 12r) so that the formation of a gap between the facing surfaces of the components can be detected with a short operation, the seal structure using a configuration in which an open groove (12a) communicated with the exteriors of the body (11) and the cover (12) is provided to the outside-air-side of the gasket (8) in the body (11) and / or the cover (12).

Description

technical field [0001] The present invention relates to a sealing structure of a part, and a gear pump or a motor using such a sealing structure. In combination, the first part and the second part have paths through which a fluid such as a working fluid flows inside. Background technique [0002] When joining parts that have passages through which fluid such as working fluid flows inside, for example, when joining between the main body (body) and cover (cover) of a gear pump, conventionally, parts An annular sealing member such as a gasket is provided between the joint surfaces facing each other to prevent the fluid from leaking to the outside (for example, refer to Patent Document 1). [0003] Furthermore, in the sealing structure of such parts, a seal groove for installing a seal member is formed in one of the first part and the second part to be joined, and the seal member is provided inside the seal groove. . However, in the step of joining the first part and the seco...
