Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, bearing sealed ring press-loading apparatus in the present embodiment, comprise the abutment sleeve 10 for being slidably matched with bearing saddle bore, coaxially be fixedly connected on the pilot sleeve 4 of described abutment sleeve 10 upper ends, the pressure head 5 of being located at abutment sleeve 10 inside and being slidably matched with abutment sleeve 10 inwalls, pilot sleeve 4 inner peripheral surfaces are provided with motion thread and are connected with screw thread depression bar 3 by this motion thread, and screw thread depression bar 3 forms feed screw nut pair with pilot sleeve 4 and screw thread depression bar 3 tops, lower end are pressed on described pressure head 5 upper-end surfaces.
In the present embodiment, described pressure head 5 comprises that the diameter of cylindrical section that a plurality of diameters are different and each cylindrical section is all greater than the diameter of its below cylindrical section, the pressure head 5 that needs diameter to match with it due to the seal ring mounting hole of different-diameter, and existing press mounting device for seal rings only can press-fit the seal ring of same diameter, seal ring for different-diameter, need to change different press mounting device for seal rings, and pressure head 5 of the present utility model, there are the different a plurality of cylindrical sections of diameter, thereby can press-fit the seal ring of plurality of specifications, improved the Applicable scope of bearing sealed ring press-loading apparatus.
In the present embodiment, described abutment sleeve 10 outer walls are provided with on flange plate 9 and described flange plate 9 and are circumferentially with a plurality of positioning holes 7 along it, when bearing sealed ring is press-fited, need first abutment sleeve 10 and bearing saddle bore to be fixed, prevent that seal ring is in press-fiting process, abutment sleeve 10 is offset, and flange plate 9 on abutment sleeve 10 outer walls can be fixed by bolt with the flange plate on bearing saddle bore end face and is connected, thereby avoid seal ring to press-fit in process, abutment sleeve 10 is moved, and then has improved the installation precision of bearing sealed ring.
In the present embodiment, on described screw thread depression bar 3, be fixed with for driving it along the operating handle of axis rotation, when bearing sealed ring is press-fited in process, operating personnel can make screw thread depression bar 3 be rotated with respect to pilot sleeve 4 by swivel lever, because rotating rotatablely moving of screw thread depression bar 3, adjutant feed screw nut is converted to the straight line motion along its axis, screw thread depression bar 3 one end promote pressure head 5 and move towards downside, thereby bearing sealed ring is clamp-oned in seal ring mounting hole.
