Description
Technical field
The utility model relates to mining equiment field, particularly relates to the excentric sleeve on a kind of gyratory crusher.
Background technology
Gyratory crusher is a kind of mining machinery for broken building stones, and its principle drives eccentric stiffener to rotate by transmission mechanism, and eccentric stiffener drives the swing of mantle group to rotate, by mantle group with surely bore frame and cooperatively interact for broken building stones.Wherein, the critical component of eccentric stiffener is excentric sleeve, but existing Eccentrical axis sleeve for cone crusher has the following disadvantages: 1, excentric sleeve is inner at bearing block by bearing location and installation, between excentric sleeve and bearing, contact offsets, thus easily there is bearing dislocation, the phenomenon that axle sleeve is impaired; 2, the outside of excentric sleeve is located by bearing, and mantle group then passes through bearing location and installation in the inside of excentric sleeve; But existing excentric sleeve is not arranged the oil circuit running through both sides inside and outside it, thus gyratory crusher needs to arrange the bearing that two lubricant passage waies are respectively used to lubricate both sides inside and outside excentric sleeve, makes lubricating wire pass by complexity.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of good positioning effect, is convenient to the Eccentrical axis sleeve for cone crusher of lubrication.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
An excentric sleeve on gyratory crusher, described excentric sleeve comprises axle sleeve inner ring, axle sleeve outer ring and axle sleeve ring, and the inner end of axle sleeve ring is connected with the outer side surface one of axle sleeve inner ring, and the outer end of axle sleeve ring is connected with the interior sidewall surface one of axle sleeve outer ring; Be configured for the upper bearing (metal) groove installing axial thrust bearing between the upper surface of described axle sleeve ring and axle sleeve inner ring, axle sleeve outer ring, between the lower surface of axle sleeve ring and axle sleeve inner ring, be configured for the lower bearing groove installing lower axial thrust bearing; Described axle sleeve inner ring comprises eccentric top and eccentric bottom, and the central through hole of eccentric bottom is positive heart through hole; The central through hole at eccentric top is communicated by shaft coupling shoulder hole with between the central through hole of eccentric bottom; Described shaft coupling shoulder hole is communicated by thin oil passage with between upper bearing (metal) groove, lower bearing groove, eccentric bottom central through hole, and lower bearing groove is communicated by thin oil passage with between eccentric bottom central through hole, upper bearing (metal) groove.
The utility model adopts technique scheme, there is the advantage of following two aspects in the excentric sleeve of this gyratory crusher: 1, form upper bearing (metal) groove between the upper surface of axle sleeve ring and axle sleeve inner ring, axle sleeve outer ring, between the lower surface of axle sleeve ring and axle sleeve inner ring, form lower bearing groove; During installation, upper axial thrust bearing is arranged in upper bearing (metal) groove, interference fit between the bottom bearing circle of upper axial thrust bearing and the axle sleeve inner ring of excentric sleeve; Lower axial thrust bearing is arranged in lower bearing groove, interference fit between the top race ring of lower axial thrust bearing and the axle sleeve inner ring of excentric sleeve; Under making upper axial thrust bearing and lower axial thrust bearing all fixedly mount excentric sleeve by this structure, not easily misplace between excentric sleeve and bearing, good positioning effect.2, the central through hole at eccentric top is communicated by shaft coupling shoulder hole with between the central through hole of eccentric bottom; Shaft coupling shoulder hole is communicated by thin oil passage with between upper bearing (metal) groove, lower bearing groove, eccentric bottom central through hole, and lower bearing groove is communicated by thin oil passage with between eccentric bottom central through hole, upper bearing (metal) groove; During installation, the central through hole of eccentric bottom passes through bearing location and installation in frame, mantle group is positioned in the central through hole at eccentric top by bearing, and the lubricating oil in frame is drained to excentric sleeve inside, and by the bearing outside thin oil passage lubrication excentric sleeve; By this structure, the bearing of both sides inside and outside a lubricant passage way and Castor Oil excentric sleeve can be realized, thus simplify lubrication circuit.
