Problems solved by technology

[0004] In the case where the washer rotates following the rotation of the bolt when the bolt is tightened and rotated, if the ductile part is extended, a load is applied to the washer, and deformation cannot be completely prevented, and since there is a cut at the junction of the washer and the coupling part, the When the joint is bent to install the washer, the joint breaks and the structure of connecting two pieces together becomes meaningless.

Embodiment Construction

[0024] Hereinafter, the best mode of the double gasket structure of the present invention shown in the drawings will be described.

[0025] An eye joint (eye joint) 1 shown in FIG. 3 to which the double gasket structure 0 of the present invention is applied has a large bolt hole 2 in the center, and a cylindrical portion 3 is formed in a direction perpendicular to the bolt hole 2. The eye joint 1 and the bolt hole 2 are concentric and form a part of a spherical surface, and at the same time form a plane parallel up and down. The oil pipe 4 is integrally embedded in the cylindrical part 3 in an oil-tight manner, and the periphery of the central part of the bolt hole 2 is The oil channel 5 communicates with the oil pipe 4.

[0026] And, the part where the eye joint 1 is installed is the pump casing 6 of the hydraulic pump not shown in the figure. The oil channel 7 in the pump casing 6 runs through the double gasket structure 0 and the eye joint 1, and the bolt 8 is screwed. Con...

Abstract

To provide a double washer structure for connecting one set of two washers through connecting portions. In this double washer structure 0 for connecting one set of two washers 10, 11 through a connecting portions 12, 13, the connecting portions 12, 13 are respectively bent in their thickness direction at right angles at respective positions apart for a prescribed distance from the one set of two washers 10, 11, and oriented in vertical direction parallel with the center line of the washers. A breaking portion 14 placing in the center of the connecting portions 12, 13 is constricted in the vertical direction and the vertical dimension of the constricted portion 17 is set so as to be smaller than the vertical dimension of other portions of the breaking portion 14.

Description

technical field [0001] The invention relates to a double washer structure in which two sets of washers are connected through a coupling part. Background technique [0002] A double washer structure with a tough part is formed by forming cutouts at both ends of the coupling part of a pair of washers connected to each other and the joint part of the washer. When fixing a bolt, the washer is in the same position as the bolt when the bolt is tightened and rotated. When the direction of rotation follows, the toughness part is easy to extend, preventing the deformation of the gasket before it happens. [0003] Patent Document 1 JP-A-2001-132722 [0004] When the bolt is tightened and rotated, and the washer rotates following the rotation of the bolt, if the flexible part is extended, a load is applied to the washer, and deformation cannot be completely prevented, and since there is a cut at the junction of the washer and the coupling part, the When the joint portion is bent for ...
