Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of snap ring for roll chock that the embodiment of the present invention provides, comprise locating ring mechanism and be connected retaining mechanism, locating ring mechanism is for accurately limiting the position of bearing block on roll, realize the location of bearing block on roll, connecting retaining mechanism for connecting upper locating ring and lower locating ring, realizing the function of the safe fixed bearing block of locking ring device;
Wherein, locating ring mechanism comprises locating ring 1 and lower locating ring 2, connect retaining mechanism and comprise connecting plate 3, upper rotating shaft 4, Shaft 5, special-shaped key 6, upper clamping screw 7 and lower clamping screw 8, upper rotating shaft 4 is welded to connect with one end of upper locating ring 1, Shaft 5 is welded to connect with one end of lower locating ring 2, connecting plate 3 is connected with Shaft 5 with upper rotating shaft 4 respectively, to realize the relative rotary motion between upper locating ring 1 and lower locating ring 2;
Upper locating ring 1 and lower locating ring 2 are fixedly linked by upper clamping screw, lower locating ring 2 and upper locating ring 1 are fixedly linked by lower clamping screw 8, one end of abnormity key 6 is connected with upper clamping screw 7, the other end of abnormity key 6 is connected with lower clamping screw 8, and special-shaped key 6 is fixed in the keyway of locating ring 1 and the formation of lower locating ring 2.
Wherein, there is an arc groove 12 inner side of upper locating ring 1 between upper clamping screw 7 and lower clamping screw 8, the arc radius of arc groove 12 is greater than locating ring 1 internal diameter 6-10 millimeter, its objective is in order to for assembling, because upper locating ring 1 and lower locating ring 2 are all arranged in the draw-in groove of roll 9 axle head, the radius of upper locating ring 1, lower locating ring 2 is identical with the radius of the draw-in groove of roll 9 axle head, like this, when snap ring 10 is half circular arc, just can be directly installed in roll 9 axle head draw-in groove.
Wherein, there is counterbore on an one end of upper locating ring 1, and upper rotating shaft 4 is welded to connect by one end of upper counterbore and upper locating ring 1, the degree of depth 5-8 millimeter of upper counterbore, the diameter of upper counterbore is that upper rotating shaft 4 diameter value adds 4-6 millimeter again, to increase the intensity that upper rotating shaft 4 welds with upper locating ring 1; There is a lower counterbore one end of lower locating ring 2, Shaft 5 is welded to connect by one end of lower counterbore and lower locating ring 2, the degree of depth 5-8 millimeter of lower counterbore, the diameter of lower counterbore is that Shaft 5 diameter adds 4-6 millimeter again, to increase the intensity that Shaft welds with lower locating ring.
Wherein, the both sides of special-shaped key 6 have first circular arc and second circular arc respectively, and first circular arc is connected with upper clamping screw 7, and second circular arc is connected with lower clamping screw 8.
The snap ring 10 that the embodiment of the present invention provides, assembling process is as follows for the first time for it:
Step 101: upper locating ring 1, lower locating ring 2 are placed according to same orientation, namely forms the orientation placement of a complete circle according to latter two locating ring of assembling;
Step 102: two of connecting plate 3 axis holes are faced respectively the upper counterbore of upper locating ring 1 and the lower counterbore of lower locating ring 2, upper rotating shaft 4, Shaft 5 are put into the upper counterbore of upper locating ring 1 and the lower counterbore of lower locating ring 2 respectively, welding rod is used upper rotating shaft 4, Shaft 5 to be welded together with upper locating ring 1, lower locating ring 2 respectively, so far, the relative rotary motion of locating ring 1 and lower locating ring 2 can be realized;
Step 103: the upper locating ring 1 after connection and lower locating ring 2 are placed in the annular groove of roll 9, after roll chock 11 and snap ring 10 assemble, a long 26-30 millimeter is formed between upper locating ring 1 and lower locating ring 2, the keyway of wide 15-18 millimeter, this keyway can be 0.5-2 millimeter in the gap at upper locating ring 1 and the closed place of lower locating ring 2, this gap appears at after upper locating ring 1 and lower locating ring 2 close, after two locating rings form a complete circle, when special-shaped key 6 is inserted, after upper clamping screw 7 and lower clamping screw 8 are fixed, this gap will reduce, its main purpose is the needs of assembling, guarantee special-shaped key 6, after upper clamping screw 7 and lower clamping screw 8 load, can compact siro spinning technology, abnormity key there will not be loosening,
Step 104: special-shaped key 6 is arranged on upper locating ring 1 and is connected in the keyway of rear formation with lower locating ring 2, after abnormity key 6 is installed, locating ring 1 can be realized and lower locating ring 2 is not having column spinner, when clamping screw, snap ring 10 is adeciduate function still, because upper locating ring 1 and lower locating ring 2 are arranged in roll 9 draw-in groove, to take out upper locating ring 1 and lower locating ring 2, just can only shift out along roll 9 draw-in groove radial direction or rotate, after the special-shaped key 6 of installation, abnormity key 6 limits the relative rotation of upper and lower two locating rings completely, also limit the relative movement of two locating rings simultaneously.
Step 105: be arranged on by upper clamping screw 7 in bolt mounting holes that upper locating ring 1, special-shaped key 6 and lower locating ring 2 formed, is arranged in another bolt mounting holes that upper locating ring 1, special-shaped key 6 and lower locating ring 2 formed by lower clamping screw 8; So far, roll chock locking ring device installs.
Repeat, in assembling use procedure, only to need the 2-5 carried out in above-mentioned assembling process to walk at daily snap ring; In addition, in actual use, upper clamping screw 7 and upper clamping screw 8 can only assembling wherein any one.
The roll chock locking ring device that the embodiment of the present invention provides, it is contrary with assembling process that it disassembles process, specific as follows:
First, clamping screw 7, lower clamping screw 8 in taking-up;
Secondly, special-shaped key 6 is taken out;
Finally, in the annular groove of roll 9, the parts that in taking-up, locating ring 1 and lower locating ring 2 link together, so far the snap ring 10 of bearing block 11 is disassembled complete.
The snap ring that the embodiment of the present invention provides, simple and reasonable for structure, disassemble conveniently, save time, long service life; The location of roll chock can be realized exactly; Safely, the connection of roll and bearing block is effectively guaranteed.
It should be noted last that, above detailed description of the invention is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to example to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
