<p><P>PROBLEM TO BE SOLVED: To provide stable sealing force with respect to outflow of lubricating oil for lubricating meshing from an internal space, infiltration of a fluid having a high pressure from an exterior, or the like. <P>SOLUTION: The gear coupling includes a coupling case 1 meshing with a coupling center 3, and a seal structure 20 sealing a space between the coupling case 1 and the coupling center 3. The seal structure 20 has a first seal member 14 closely contacting the coupling center 3 throughout a whole circumference, a ring member 10 disposed on an outer circumference of the coupling center 3 and pressing a whole of the first seal member 14 fit in an inner circumference face against the coupling center 3, and a pressing plate 11 and a shim 16 provided in the coupling case 1, shielding the internal space 5 formed by the coupling case 1 and the coupling center 3, and supporting the ring member 10 such that it can freely move in a radial direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
