The present invention relates to the improvement that both sides is had the integrated type thrust-bearing of the flat circle that rolls.
The structure of existing thrust-bearing as shown in Figure 4, the maintenance window frame on the retainer 3 is used for putting needle roller 2.The flat circle 4 that rolls is supporting the outer garden of retainer 3, and this Ping Quan matches with the annular groove a that opens on rotating object A end face.It just can rotate together with rotary article A like this.Another flat circle 5 of rolling matches with groove b.Groove b opens on rearward the part B, and part B is facing to the end face of rotating object A.Perhaps roll and one or several screw are housed on the flat circle 5, this flat circle is contained on the part B behind one or several holes, omitted among a kind of method figure in back.The shortcoming of this class formation be thrust-bearing installation be connected difficulty, reason be to roll flat circle 4 does not link to each other mutually with 5.
So, integrated type thrust-bearing has as shown in Figure 5 appearred, and this bearing curves another inner edge that rolls flat circle L shaped on profile direction, formed an anastomosis part 6, and anastomosis part 6 connects together two flat circles 4 and 5 that roll by retainer 3.Like this, thrust-bearing can easily be installed and engage, just needn't go up fluting b by part B rearward, this part B is facing to the end face of rotating object A.
When the rotating object A of existing integrated type thrust-bearing and horizontal positioned assembling, as shown in Figure 5, maintenance window frame 1 on the retainer 3 is equipped with some needle rollers 2, and the lower end in the outer garden of retainer is connected with the flat bottom of enclosing the circular groove 7 on 4 one side of rolling, and the flat circle 4 that rolls is supporting the outer garden of retainer 3.Another installation of rolling flat circle 5 is that the anastomosis part 6 that child-care center forms in it is connected with the interior garden of retainer 3.The flat circle 4 that rolls links together with retainer 3, and when the flat circle 4 that rolls began to rotate, retainer 3 also began to have rotated.During installation, retainer is positioned at following position because of its deadweight.During rotation, under the rotating center of the rotating center that makes retainer and object A coincided the concentric effect of this trend, retainer 3 upwards floated, up to its rotating center with till the rotating center of rotating object A overlaps.Therefore, existing integrated type thrust-bearing has important shortcoming: when promptly this Bearing Installation went up to the rotating object A of horizontal positioned, the Nei Yuan end of retainer 3 just contacted with another flat anastomosis part 6 of enclosing on 5 of rolling.During rotation, will cause contacting the inordinate wear of part, the result makes the lost of life of this integrated type thrust-bearing.
Therefore, the present invention intends providing a kind of shortcoming , And that can overcome above-mentioned existing integrated type thrust-bearing can stand long-time use, the integrated type thrust-bearing that reliability is high.
Produced the present invention for addressing the above problem, the present invention is that a kind of integrated type thrust-bearing is characterized in that: the flat circle of the rolling that extends to the retainer two ends is arranged, some needle rollers are housed in the window frame of retainer, the outer garden of retainer is being supported in the interior garden of the flat circle that rolls, and the interior child-care center that another flat circle that rolls is held frame supports.Its feature also is: the flat circle that rolls of integrated type thrust-bearing is fitted on Yi Qi And with rotating object Zhuan and rotates therewith, and the convex portion on another flat circle that rolls matches with part behind, and this part surface is facing to the end face of rotating object.
The structure of integrated type thrust-bearing of the present invention is with top described the same.Therefore, when it was installed on the rotating object that horizontally rotates, another that is held that the garden is supported in the frame flat circle that rolls was connected with interior garden, outer ring or groove on the part behind, and this back part surface faces toward the end face of rotating object.The installation of the flat circle of this rolling is not subjected to the influence of retainer.Therefore, when retainer rotated, when it floated under with the effect of mental and physical efforts, its Nei Yuan end did not contact with the internal surface that the flat circle of rolling that retainer is supported is gone up the anastomosis part.So just can not cause inordinate wear.
Exemplary embodiments of the present invention is described in detail with reference to accompanying drawing:
(A) among Fig. 1, (B), (C) are under operating conditions, the sectional view of integrated type thrust-bearing Lower Half of the present invention, each graph expression different embodiments, the code name of being given among the figure is identical with the corresponding part of Fig. 5.
In the integrated type thrust-bearing of the exemplary embodiments shown in Fig. 1 (A), there is convex portion 8 another Nei Yuan end of rolling flat circle 5, and this convex portion 8 is contained on the interior garden C of behind part B, and this part surface is facing to the end face of rotating object A.
Fig. 2 is the stereogram of another the flat circle 5 that rolls shown in Fig. 1 (A), in Fig. 2 clear expression like that, in this embodiment, another flat interior garden of enclosing on 5 of rolling, alternately outwardly-bent inwards at certain intervals on the Zhou Fangxiang of its garden, formed anastomosis part 6 and convex portion 8 respectively.
In addition, in the integrated type thrust-bearing of the exemplary embodiments shown in Fig. 1 (B), have in another Wai Yuan end of rolling flat circle 5 convex portion 8 ', on the outer garden d of part B, this part B is in the face of the end face of rotating object A behind for this convex portion 8 ' be contained in.
Fig. 3 is the stereogram of the flat circle 5 of another rotation shown in Fig. 1 (B).As Fig. 3 know expression like that, in this embodiment, convex portion 8 is not on the limit in garden in another rolls flat circle 5, but put down rolling 5 the outer garden enclosed outwards curve the convex portion 8 of a link spring shape '.Can also the outer garden of the flat circle 5 that rolls on the Zhou Fangxiang of garden, outwards curve at certain intervals convex portion 8 ', it is not the garden annular, but the same with convex portion shown in Figure 28.
