Abstract
The utility model relates to a vertical mill roller sleeve compaction structure which comprises a press ring, a roller core, a self-locking nut and a double-screw bolt, wherein a boss is arranged at the circumference of the roller core; a threaded hole matched with the double-screw bolt is formed in the boss; the press ring is connected with the boss through the self-locking nut and the double-screw bolt; and an adjusting washer is arranged between the press ring and the boss. Due to arrangement of the boss connected with the double-screw bolt and adoption of a locking mode based on the double-screw bolt and the self-locking nut, the machining is convenient, the consumption of base metal is saved under the condition that the locking strength is ensured.
Description
Technical field
The utility model relates to a kind of vertical roller grinder technical field, relates in particular to a kind of roller shell compressing structure.
Background technology
What the hold down gag of Present Domestic vertical grinding roll cover adopted is to connect by shank of bolt, pressure ring is connected with roller shell and locks.Use this hold down gag, long bolt need to run through roller core, and stay bolt bar needs customized, processes loaded down with trivial details and increases mother metal consumption, and long bolt intensity is also low, increases equipment cost.
Utility model content
For above problem the utility model, provide a kind of more simple and reliable vertical grinding roll cover compressing structure.
In order to overcome the above problems the utility model, provide a kind of vertical grinding roll cover compressing structure, comprise pressure ring, roller core, it is characterized in that: also comprise by Self-lock nut, studs, on described roller core circumference, be provided with boss, on boss, be provided with the screwed hole matching with studs, pressure ring is by being connected with boss with studs by Self-lock nut.Between described pressure ring and boss, be provided with adjustment packing ring.
The utility model is owing to having increased the boss being connected with studs, and adopts the locking mode of studs and Self-lock nut, processes more conveniently, guaranteed locking intensity when having saved mother metal consumption.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model patent.
In Fig. 1: 1-Self-lock nut; 2-studs; 3-pressure ring; 4-adjustment packing ring; 5-roller shell; 6-roller core; 7-boss; 8-screwed hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of vertical grinding roll cover compressing structure, comprises by Self-lock nut 1, studs 2, pressure ring 3, adjusts packing ring 4, roller core 6, on described roller core 6 circumference, be provided with boss 7, on boss 7, be provided with the screwed hole 8 matching with studs 2; Between pressure ring 3 and boss 7, be provided with and adjust packing ring 4; Pressure ring 3 is by being connected with boss 7 with studs 2 by Self-lock nut 1.
Erection sequence: pack roller shell 5 into roller core 6, pack into and adjust packing ring 4, be pressed into pressure ring 3, roller shell 5 tensioners, on roller core 6, are loaded on to studs 2, finally tighten Self-lock nut 1, locking pressure ring, thus compress roller shell.
The foregoing is only preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
