Title:
ONE SIDE ADHESION TYPE SEPARATE COLLAR
Document Type and Number:
Japanese Patent JP2003021119
Kind Code:
A
Abstract:

To provide a one side adhesion type separate collar, improving a problem of a conventional separate collar, enhancing an adhesive property by providing an adhesive side and a non-adhesive side on a separate collar and transmitting bending moment to the whole of the collar at the time of fastening of the non-adhesive side, and preventing the breakage of a bolt by preventing the generation of irregular stress due to a deformation of the collar, and to improve the efficiency of attaching work by facilitating fine adjustment of an attached position.

This separate collar is provided with an adhesive side 2 and a non-adhesive side 3, and a bolt 4a in the adhesive side 2 is fastened to be adhered. The non-adhesive side 3 is fastened by a bolt 4b and bending moment is transmitted to the whole of the collar, thereby improving an adhesive property of a collar inner surface. An abutting surface of the bolt 4b of a fastening portion in the non adhesive side 3 is machined to be a spherical surface 6, thereby adhering the spherical surface to an acting surface 7 on an outer periphery of a bolt hole 5. An irregular deformation of the bolt abutting surface generated by a deformation of the collar is solved to prevent the breakage of the bolt.
