The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of snap ring for roll chock that the embodiment of the invention provides, comprise locating ring mechanism and be connected retaining mechanism, locating ring mechanism is used for accurately limiting the position of bearing block on roll, realize the location of bearing block on roll, connect retaining mechanism and be used for connecting upper locating ring and lower locating ring, realize 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 flexibly connected with an end of upper locating ring 1, Shaft 5 is flexibly connected with an end of lower locating ring 2, connecting plate 3 links to each other with Shaft 5 with upper rotating shaft 4 respectively, to realize the relative rotary motion between upper locating ring 1 and the lower locating ring 2;
Upper clamping screw is fixedly linked upper locating ring 1 and lower locating ring 2, lower clamping screw 8 is fixedly linked lower locating ring 2 and upper locating ring 1, one end of abnormity key 6 links to each other with upper clamping screw 7, the other end of abnormity key 6 links to each other with lower clamping screw 8, and special-shaped key 6 is fixed in the keyway of locating ring 1 and 2 formation of lower locating ring.
Wherein, there is an arc groove 12 inboard 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 upper locating ring 1 internal diameter 6-10 millimeter, its objective is in order to be used for assembling, because upper locating ring 1 and lower locating ring 2 all are installed in the draw-in groove of roll 9 axle heads, 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 heads, like this, when snap ring 10 is half circular arc, just can be directly installed in the roll 9 axle head draw-in grooves.
Wherein, one end of upper locating ring 1 has counterbore on, and upper rotating shaft 4 is flexibly connected the degree of depth 5-8 millimeter of upper counterbore by an end of upper counterbore and upper locating ring 1, the diameter of upper counterbore is that upper rotating shaft 4 diameter values add the 4-6 millimeter again, the intensity of welding to increase upper rotating shaft 4 and upper locating ring 1; One end of lower locating ring 2 has a lower counterbore, Shaft 2 is flexibly connected by an end of lower counterbore and lower locating ring 2, the degree of depth 5-8 millimeter of lower counterbore, the diameter of lower counterbore are that Shaft 5 diameters add the 4-6 millimeter again, to increase the intensity of Shaft and lower locating ring welding;
Wherein, there are respectively first circular arc and second circular arc in the both sides of special-shaped key 6, and first circular arc links to each other with upper clamping screw 7, and second circular arc links to each other with lower clamping screw 8.
The snap ring 10 that the embodiment of the 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 formed the orientation placement of a complete circle according to latter two locating ring of assembling;
Step 102: the lower counterbore that two axis holes of connecting plate 3 is faced respectively upper counterbore and the lower locating ring 2 of upper locating ring 1, upper rotating shaft 4, Shaft 5 are put into respectively the lower counterbore of upper counterbore and the lower locating ring 2 of upper locating ring 1, use welding rod respectively upper rotating shaft 4, Shaft 5 to be welded together with upper locating ring 1, lower locating ring 2, so far, can realize the relative rotary motion of locating ring 1 and lower locating ring 2;
Step 103: the upper locating ring 1 after will connecting and lower locating ring 2 are placed in the annular groove of roll 9, after roll chock 11 assembles with snap ring 10, between upper locating ring 1 and lower locating ring 2, form a long 26-30 millimeter, the keyway of wide 15-18 millimeter, this keyway can be the 0.5-2 millimeter in the gap at upper locating ring 1 and lower locating ring 2 closed places, this gap appears at after upper locating ring 1 and lower locating ring 2 closures, after two locating rings form a complete circle, when special-shaped key 6 is inserted, after upper clamping screw 4 and lower clamping screw 5 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 are packed into, can closely connect, becoming flexible can not appear in special-shaped key;
Step 104: special-shaped key 6 is installed in upper locating ring 1 is connected with lower locating ring 2 in the rear keyway that forms, after abnormity key 6 is installed, can realize that locating ring 1 and lower locating ring 2 are not having column spinner, in the absence of clamping screw, snap ring 10 is adeciduate function still, because upper locating ring 1 and lower locating ring 2 are installed in roll 9 draw-in grooves, if take out locating ring 1 and lower locating ring 2, just can only radially shift out or rotate along roll 9 draw-in grooves, after special-shaped key 6 is installed, special-shaped key 6 has limited the up and down relative rotation of two locating rings fully, has also limited relatively moving of two locating rings simultaneously.。
Step 105: upper clamping screw 7 is installed in the bolt mounting holes of upper locating ring 1, special-shaped key 6 and 2 formation of lower locating ring, lower clamping screw 8 is installed in another bolt mounting holes of upper locating ring 1, special-shaped key 6 and 2 formation of lower locating ring; So far, the roll chock locking ring device installs.
Repeat to assemble in the use procedure at daily snap ring, the 2-4 step that only need to carry out in the above-mentioned assembling process gets final product; In addition, in actual use, upper clamping screw 7 and upper clamping screw 8 only assembling wherein any one.
The roll chock locking ring device that the embodiment of the invention provides, it is opposite with assembling process that it disassembles process, specific as follows:
At first, clamping screw 7, lower clamping screw 8 in the taking-up;
Secondly, take out special-shaped key 6;
At last, in the annular groove of roll 9, the parts that locating ring 1 and lower locating ring 2 link together in the taking-up, so far the snap ring 10 of bearing block 11 is disassembled complete.
The snap ring that the embodiment of the invention provides, simple and reasonable for structure, disassemble conveniently, save time long service life; Can realize exactly the location of roll chock; Safety, effectively guarantee being connected of roll and bearing block.
It should be noted last that, the above specific embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to example the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
