It is seamed into curved.Thus, flange 4 is further bitten by making sleeve 2, sleeve 2 and flange 4 can be firmly fixed.In addition,
Since the end of roller 16 and sleeve 2 carries out point contact, so effectively pressure can be applied to the end of sleeve 2.
Due to making the roller 16,16,16 that three of side are one group with three of the other side for one group of roller 16,16,16
It is also axially moveable while mutually rotation in reverse direction, so the deformation other than the end of sleeve 2 can be inhibited.
Ca(u)lk processing it is last during, due to roller 16 peripheral surface (machined surface) 16a inner arc surface 16c with set
The end contact of cylinder 2, so the end of sleeve 2 can further be made to bite into flange 4 securely.At this point, producing prodigious
Be pushed axially the power of sleeve 2, but due to some bite, make sleeve 2 that the power of slight bending degree occur not
It can lead to the deformation of sleeve 2, and the decline of dimensional accuracy will not be caused.
Due to forming annular knurl 40 in the end of flange 4, and chamfering is not carried out to the end of the flange 4, so relative to
The annular knurl 40 by 2 ca(u)lk of sleeve at curved surface, therefore sleeve 2 bite it is good.In addition, due to being arranged on the peripheral surface of sleeve 2
Slot 20, therefore roller 16 carries out point contact with the protrusion other than the slot 20, so it is curved so that the end of sleeve 2 is become easy
It is bent.
