Abstract
A kind of spherical bush, comprise spherical bush body, in sand cleaning hole on described spherical bush body end face, be provided with for sealing the hexagonal socket head plug of sand cleaning hole, described hexagonal socket head plug is for being with externally threaded Rotary-table structure, and Rotary-table large end face center offers an interior hexagonal hole.In spherical bush in the utility model adopts, six side's plug screws seal sand cleaning hole, the large end face of its interior six side's plug screws is lower than the end face of spherical bush, with regard to not needing, by lathe, carry out smooth processing like this, saved cost, avoided the smooth fresh processed problem of weight occurring when processing unsuccessfully simultaneously, save the set-up time, thereby improved efficiency.
Description
Technical field
The utility model relates to the device that a kind of rotary kiln device is used, and especially relates to a kind of spherical bush.
Background technology
Bearing of conveyor idler group device is bearing rotating cylinder weight, weight of material and the rotating cylinder liner weight of rotary kiln, and load is huge.Spherical bush is the vital part of supporting roller of rotary kiln bearing group, spherical bush is contained on spheric seating with ball faying face, the substantial load of rotary kiln is all delivered on support roller by the wheel band on cylindrical shell, spherical bush plays regulatory role in riding wheel apparatus, makes riding wheel apparatus can well adapt to the unbalance stress being caused compared with small deformation or alignment error by cylindrical shell.Therefore in spherical bush, need water flowing to cool, Wa Ti center is cavity.Due to casting technique requirement, need stay husky clearly hole in the both ends of the surface that do not stress, the residual sand in watt body cavity is cleared, simultaneously in order to guarantee the closure of cavity, after clear complete sand, need sand cleaning hole to block.Because both ends of the surface also will be installed the parts such as briquetting, finally both ends of the surface need be processed smoothly, must not exceed both ends of the surface.Existing spherical bush is mainly with the stifled sand cleaning hole of outer six side's plug screws, then goes up machine tooling smooth.If the direction of processing is not right, outer six side's plug screws can not block up sternly, and pressure testing test will be leaked, and scene also likely leaks, and wants again to tighten to do some frocks, and then removes.
Utility model content
The purpose of this utility model is for solving the problem of existing spherical bush sand cleaning hole sealing trouble, a kind of spherical bush is provided, in spherical bush in the utility model adopts, six side's plug screws seal sand cleaning hole, the large end face of its interior six side's plug screws is lower than the end face of spherical bush, with regard to not needing, by lathe, carry out smooth processing like this, saved cost, avoided the smooth fresh processed problem of weight occurring when processing unsuccessfully simultaneously, save the set-up time, thereby improved efficiency.
The utility model is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
A kind of spherical bush, comprise spherical bush body, in sand cleaning hole on described spherical bush body end face, be provided with for sealing the hexagonal socket head plug of sand cleaning hole, described hexagonal socket head plug is for being with externally threaded Rotary-table structure, and Rotary-table large end face center offers an interior hexagonal hole.
The round platform large end face of described hexagonal socket head plug is lower than the end face of spherical bush body.
The beneficial effects of the utility model are: in the spherical bush in the utility model adopts, six side's plug screws seal sand cleaning hole, the large end face of its interior six side's plug screws is lower than the end face of spherical bush, with regard to not needing, by lathe, carry out smooth processing like this, saved cost, avoided the smooth fresh processed problem of weight occurring when processing unsuccessfully simultaneously, save the set-up time, thereby improved efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Graphical indicia: 1, end face; 2, sand cleaning hole; 3, hexagonal socket head plug; 4, spherical bush body.
The specific embodiment
Shown in figure, the specific embodiment is as follows:
A kind of spherical bush, comprise spherical bush body 4, in sand cleaning hole 2 on described spherical bush body 4 end faces 1, be provided with for sealing the hexagonal socket head plug 3 of sand cleaning hole 2, described hexagonal socket head plug 3 is for being with externally threaded Rotary-table structure, and Rotary-table large end face center offers an interior hexagonal hole.
The round platform large end face of described hexagonal socket head plug 3 is lower than the end face 1 of spherical bush body 4.
At spherical bush two ends sand cleaning hole, attack corresponding sealing internal thread, screw on and be processed with the externally threaded interior six side's plug screws of corresponding sealing after sand removal, the outer end face of plug screw is screwed into below spherical bush end flat.As pressure testing is leaked, available spanner is filled in interior hexagonal hole and is continued to tighten.As plug screw defectiveness, also can back-out and more renew plug screw.
The utility model is simple in structure, it is convenient to install and change, and do not use lathe and processes unnecessary amount and just can guarantee sand cleaning hole tightness.
The technical scheme that the utility model is cited and embodiment are not restrictions, in the cited technical scheme of the utility model and embodiment is equal to or effect same approach is all protected at the utility model scope.
