Abstract

A motor including a first member and a second member each having an annular shaped cross-section, a semi-metallic gasket for sealing between the first member and the second member, and a method for sealing the motor using the semi-metallic gasket. The semi-metallic gasket includes an annular shaped bead portion and portions to be sucked by a suction hand. The portions to be sucked project from the bead portion along the wall width direction of the bead portion.

Claims (20)

1 . A semi-metallic gasket provided in a motor equipped with a first member and a second member each having an annular shaped cross section, the semi-metallic gasket being configured to seal a gap between the first member and the second member, the semi-metallic gasket comprising:

a bead portion having an annular shape and made of a semi-metallic material; and

at least two portions to be sucked configured to be held under suction by a suction hand of a robot,

wherein the portion to be sucked projects out from the bead portion along a width direction of the bead portion,

the annular shape of the bead portion is point-symmetrical with respect to a center point of the annular shape of the bead portion, and

the two portions to be sucked are arranged in a manner so as to sandwich an imaginary straight line passing through one point on the bead portion having the annular shape and the center point.

2 . The semi-metallic gasket according to claim 1 , wherein the first member and the second member are connected by a plurality of connecting members,

the semi-metallic gasket further comprising a plurality of insertion portions each including a hole into which each of the plurality of connecting members is inserted,

wherein the plurality of insertion portions are provided in the bead portion in point-symmetry with respect to the center point.

3 . A motor in which the semi-metallic gasket according to claim 1 is provided, the motor comprising the first member and the second member,

wherein a gap between the first member and the second member is sealed by the semi-metallic gasket.

4 . A motor sealing method for, by using a semi-metallic gasket, sealing a gap between a first member and a second member provided in a motor, wherein the first member and the second member each have an annular shaped cross section,

the semi-metallic gasket including:

a bead portion having an annular shape and made of a semi-metallic material; and

a portion to be sucked configured to be held under suction by a suction hand of a robot,

wherein the portion to be sucked projects out from the bead portion along a width direction of the bead portion,

the motor sealing method comprising:

a suction step of holding the portion to be sucked of the semi-metallic gasket, under suction by the suction hand;

a placement step of placing the semi-metallic gasket held under suction by the suction hand, on the first member of the motor; and

a close contact step of bringing the second member of the motor into close contact with the semi-metallic gasket from a side opposite to a side where the first member is disposed.
