The specific embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
Consult accompanying drawing 1.
Embodiment 1
The provision for disengagement of a kind of endoporus self-lubricating bearing comprises expansion set 1, back-up ring 2, jacking bolt 3, voussoir 6 and cinch bolt 4; Cinch bolt 4 passes back-up ring 2, expansion set 1, adopts engage thread to be connected with the voussoir 6 that is positioned at expansion set 1.Two inclined-planes of voussoir 6 are symmetrical, along the self-lubricating bearing axis direction threaded through hole arranged in the middle of the voussoir 6, and cinch bolt 4 is housed in the through hole.Expansion set 1 forms by two, and expansion set 1 outside diameter is slightly less than self-lubricating bearing 5 diameter of bores, and expansion set 1 cylindrical has hatching knurling with the working face that self-lubricating bearing 5 endoporus cooperate, and does surface hardening and process; In the middle of the expansion set 1 the wedge shape endoporus is arranged, there is a raised flanges expansion set outer, and flange is equipped with jacking bolt 3 along 2 tapped through holes are arranged in the tapped through hole.
Cinch bolt moves axially along expansion set by voussoir, and expansion set is radially dilated the swelling of self-lubricating bearing endoporus, and jacking bolt mounted in pairs is used for the jacking expansion set on expansion set, expansion set is together taken apart from bearing saddle bore housing 7 together with self-lubricating bearing.
The specific implementation process of present embodiment:
With the provision for disengagement of endoporus self-lubricating bearing by Fig. 1 self-lubricating bearing 5 endoporus of packing into.Attention: before the dress cinch bolt 4 is suitably unclamped, adjust two expansion sets 1, make it to insert dead eye.Tighten cinch bolt 4, make voussoir 6 along bearing shaft to outside movement, like this, two expansion sets 1 outwards dilate, its cylindrical working face and brearing bore swelling.Tighten synchronously two jacking bolts 3, when the head of jacking bolt 3 during near bearing saddle bore housing 7 surface, can be filling up stalloy between bolt 3 heads and bearing saddle bore housing 7 surfaces, in order to avoid bearing saddle bore housing 7 is surperficial impaired.Continue to tighten synchronously two jacking bolts 3, the provision for disengagement of a whole set of endoporus self-lubricating bearing is mobile outside bearing mounting hole along bearing axis.Because cylindrical working face and the brearing bore swelling of two expansion sets 1, and the cylindrical working face of two expansion sets 1 has carried out annular knurl and Quenching Treatment, under the frictional force effect on expansion set cylindrical working face and brearing bore surface, self-lubricating bearing 5 together breaks away from bearing mounting hole with the provision for disengagement of a whole set of endoporus self-lubricating bearing, realizes the dismounting of self-lubricating bearing 5.
Present embodiment has simple in structure, and is easy to use, with low cost, economical and practical, and the characteristics such as long service life can disassemble engineering machinery gear pump case self-lubricating bearing efficiently and easily.
