Advantage and good effect that the present invention has are:
Self-lubricating bearing provision for disengagement has been owing to having adopted the brand-new technical scheme of the present invention, compared with prior art, and the effective containment vessel body of the present invention bearing mounting hole.Adopt the swelling of voussoir inclined-plane, expansion set and bearing pressure are large; Expansion set cylindrical working face annular knurl Quenching Treatment, can not only improve the frictional force of expansion set cylindrical working face and bearing surface, and improve expansion set service life.The present invention has simple in structure, easy to use, economical and practical, can be widely used in the advantages such as dismounting of engineering machinery gear pump case self-lubricating bearing.
Accompanying drawing explanation
Fig. 1 is self-lubricating bearing provision for disengagement structural representation.
In figure, 1, expansion set; 2, gear chock; 3, jacking bolt; 4, cinch bolt; 5, self-lubricating bearing; 6, voussoir; 7, bearing saddle bore housing.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
A self-lubricating bearing provision for disengagement, comprises expansion set 1, gear chock 2, jacking bolt 3, voussoir 6 and cinch bolt 4; Cinch bolt 4, through gear chock 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, in the middle of voussoir 6, along self-lubricating bearing axis direction, have threaded through hole, and cinch bolt 4 is housed in through hole.Expansion set 1 forms by two, and expansion set 1 outside diameter is slightly less than self-lubricating bearing 5 diameters, and expansion set 1 cylindrical has hatching knurling with the working face that self-lubricating bearing 5 coordinates, and does surface hardening and process; In the middle of expansion set 1, have wedge shape, there is a raised flanges expansion set outer, and flange, along there being 2 tapped through holes, is equipped with jacking bolt 3 in tapped through hole.
Cinch bolt moves axially along expansion set by voussoir, and expansion set is radially dilated self-lubricating bearing swelling, and jacking bolt mounted in pairs, on expansion set, for jacking expansion set, together takes apart expansion set together with self-lubricating bearing from bearing saddle bore housing 7.
The specific implementation process of the present embodiment:
By Fig. 1, pack self-lubricating bearing provision for disengagement into self-lubricating bearing 5.Attention: before 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 bearing swelling.Synchronously tighten two jacking bolts 3, when the head of jacking bolt 3 approaches bearing saddle bore housing 7 surface, can be padding stalloy between bolt 3 heads and bearing saddle bore housing 7 surfaces, in order to avoid the surface of bearing saddle bore housing 7 is impaired.Continue synchronously to tighten two jacking bolts 3, a whole set of self-lubricating bearing provision for disengagement is moved outside bearing mounting hole along bearing axis.Cylindrical working face and bearing swelling due to 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 of expansion set cylindrical working face and bearing surface, self-lubricating bearing 5 together departs from bearing mounting hole with a whole set of self-lubricating bearing provision for disengagement, realizes the dismounting of self-lubricating bearing 5.
The present embodiment has simple in structure, easy to use, with low cost, economical and practical, and the features such as long service life can disassemble engineering machinery gear pump case self-lubricating bearing efficiently and easily.
