Abstract
The utility model provides a draw-casting machine structure for axial positioning and mechanical transmission, which is applied to the technical field of mechanical control. The draw-casting machine structure comprises a screw rod (1), a bearing support (2), a gland (3), a bevel gear (4), an upper bearing cap (6), a thrust bearing (7), a lower bearing cap (8), a cylindrical bearing (9), and a spacer sleeve (10), wherein the draw-casting machine structure is not provided with a nut (14), and a hough (5) assembled and matched the screw rod is arranged in the bearing support (2). Due to the adoption of the structure provided by the utility model, the problem in axial positioning of the screw rod can be effectively controlled by the axle sleeve of the hough, the thrust bearing and the cylindrical bearing can be replaced or inspected conveniently, when the bearing is replaced or inspected, only the bevel gear is required to be dismounted, the screw rod is hoisted by a traveling crane, and then the hough can be taken out. The structure is simple to demount, and the maintenance time and the maintenance amount can be reduced.
Description
Technical field
The utility model relates to mechanical control technology field, in particular, relates to a kind of axially cast machine structure of location of machine driving that is used for.
Background technology
Former semicontinuous cast machine is by motor, cycloidal-pin wheel, shaft coupling, the rotation of bevel gear driving-belt movable wire bar, do upper and lower moving with the screw mandrel nut engaged, cast machine and nut fuse, and the cast machine is done upper and lower moving with nut like this, finishes strand cast needs, because cast machine load is bigger, corrosivity is big, environment is abominable, and the bearing lubrication effect is relatively poor, therefore, in running, thrust bearing and cylindrical bearing are shorter service life.The adjusting of employing nut, the fastening axial location problem of controlling screw mandrel on thrust bearing, this setscrew nut dismounting earlier when replacing or inspection bearing, because there is corrosion in nut, dismounting is very difficult in the process, frequent dismounting, the thread form well damage of screw mandrel and nut has reduced screw axis to positioning accuracy, rock greatlyyer when causing the cast machine to move up and down, influenced product quality.Concrete structure is shown in Figure 3.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can effectively control screw axis to orientation problem, be convenient to change or check the cast machine structure of thrust bearing and cylindrical bearing.
Solve above-described technical problem, the technical scheme that the utility model is taked is:
The utility model is a kind of cast machine structure, comprises screw mandrel, bearing block, gland, bevel gear, upper ball cover, thrust bearing, lower ball cover, cylindrical bearing, spacer, described cast machine structure cancellation nut is provided with the Hough that cooperates installation with screw mandrel in the described bearing block.
Described Hough inner chamber is provided with along the boss face of the projection in one week of its inwall, is provided with on the described screw mandrel along the screw mandrel groove in one week, and described boss face and groove fit are installed.
Described Hough is set to the structure be made up of two semicircular structures, and described Hough is installed in the Hough axle sleeve.
Described Hough axle sleeve is set to be installed on bearing block, the structure on the inwall of the concave station face that gland constitutes.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Structure of the present utility model, can effectively control screw axis by the Hough axle sleeve to orientation problem, also be convenient to change or check thrust bearing and cylindrical bearing problem, when replacing or inspection bearing, only need the bevel gear dismounting is sling screw mandrel with driving, Hough can be taken out, this structure dismounting is simple, has reduced maintenance time and maintenance capacity.

The specific embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail embodiment:
Shown in accompanying drawing 1, accompanying drawing 2, the utility model is a kind of cast machine structure, comprises screw mandrel 1, bearing block 2, gland 3, bevel gear 4, upper ball cover 6, plane bearing 7, lower ball cover 8, cylindrical bearing 9, spacer 10, described cast machine structure cancellation nut 14 is provided with the Hough 5 that cooperates installation with screw mandrel in the described bearing block 2.
Described Hough 5 inner chambers are provided with along the boss face 11 of the projection in one week of its inwall, are provided with on the described screw mandrel 1 along the groove 12 in 1 one weeks of screw mandrel, and described boss face 11 cooperates installation with groove 12.
Described Hough 5 is set to the structure be made up of two semicircular structures, and described Hough 5 is installed in the Hough axle sleeve 15.
Described Hough axle sleeve 15 is set to be installed on bearing block 2, the structure on the inwall of the concave station face 13 that gland 3 constitutes.
Structure of the present utility model, nut above the thrust bearing 7 14 is removed, processing one cover Hough 5, external screw thread place with screw mandrel 1 processes groove 12 simultaneously, thereby cooperate installation with the boss face 11 on the Hough 5, like this, the axial location problem of screw mandrel 1 be can effectively control by Hough 5, thrust bearing 7 and cylindrical bearing 9, structure of the present utility model also are convenient to change or check, when replacing or inspection bearing, only need bevel gear 4 dismountings are sling screw mandrel 1 with driving, Hough 5 can be taken out, this structure dismounting is simple, has reduced maintenance time and maintenance capacity.
In maintenance process, when gap that need to change thrust bearing 7, cylindrical bearing 9 and screw mandrel 1 is adjusted, only need main transmission bevel gear 4 and axle are removed, remove gland 3, screw mandrel sling simultaneously to the appropriate location, can take out Hough 5, upper ball cover 6, thrust bearing 7 and cylindrical bearing 9 etc. easily.
Structure of the present utility model, simple and practical, easily manufactured, improvement cost is few.It is convenient to transform the back maintenance, has improved the screw mandrel positioning accuracy, has promoted product quality.Simultaneously, solved the assembling difficult problem, improved assembly precision simultaneously, saved maintenance time and maintenance capacity, enhanced productivity.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
