Abstract

The utility model discloses a novel grinding roller assembly. The novel grinding roller assembly comprises a bearing assembly room, a grinding roller shaft, a grinding roller, a grinding roller shaft upper nut, a retaining washer and a grinding roller shaft lower nut, wherein the grinding roller shaft runs through the whole grinding roller assembly; the bearing assembly room is arranged at the upper end of the grinding roller shaft; the grinding roller is arranged at the lower end of the grinding roller shaft; the grinding roller shaft upper nut and the grinding roller shaft lower nut are arranged at the lower end of the grinding roller shaft; the retaining washer is arranged between the grinding roller shaft upper nut and the grinding roller shaft lower nut; and the outer diameter of the grinding roller is 400mm. The novel grinding roller assembly is characterized in that: the inner diameter of the grinding roller is 260mm; the diameter of a connecting position of the grinding roller shaft and the grinding roller is 260mm; and the diameter of a contact position of the grinding roller shaft and the grinding roller is maximum. By the novel grinding roller assembly, the weight of a single novel grinding roller is reduced by about 35 percent, and the using effect is not affected; and the problem of material waste is effectively solved when the novel grinding roller assembly is used.

Description

A kind of novel grinding roller assembly

Technical field

The utility model relates to a kind of novel grinding roller assembly, and this technical application is on Raymond mill or high pressure overhang roll flour mill.

Background technology

Grinding roller on the flour mill be a kind of consumption very consumable accessory, and the new about 400mm of grinding roller external diameter of present 5R, the about 100mm of internal diameter; According to general operating position; When the grinding roller service efficiency was extremely low or out of use for some reason, the grinding roller external diameter generally also had 300mm, and the grinding roller that therefore changes ninety-nine times out of a hundred all is the about 300mm of external diameter; The useless grinding roller of the about 100mm of internal diameter, the old grinding roller after the replacing can only be as the recycling of waste metal goods and materials.

Prior art exists following two shortcomings:

First: the grinding roller assembly is designed with defective, and waste is serious in the time of use;

Second: it is very big to change the grinding roller workload, and very difficulty is sometimes pushed up to come out with 400 tons hydraulic jack yet; The words of not coming out in the top can only be by damage property dismounting mode; Promptly grinding roller is cut off, but because the damaged about 100mm of grinding roller thickness is time-consuming hard with oxygen-acetylene cutter.

Summary of the invention

The technical problem that the utility model will solve is to overcome deficiency of the prior art and a kind of novel grinding roller assembly is provided.

The technical scheme that the utility model adopts is:

A kind of novel grinding roller assembly comprises bearing assembly chamber, grinding roller axle, grinding roller, the top nut of grinding roller axle, floor clip and grinding roller axle lower nut, and the grinding roller axle runs through whole grinding roller assembly; The bearing assembly chamber is arranged on the upper end of grinding roller axle; Grinding roller is installed in the lower end of grinding roller axle, and grinding roller axle lower end is provided with top nut of grinding roller axle and grinding roller axle lower nut, is provided with floor clip between top nut of grinding roller axle and the grinding roller axle lower nut; Grinding roller external diameter 400mm is characterized in that: the internal diameter of said grinding roller is 260mm; The diameter of said grinding roller axle and said grinding roller connecting portion is 260mm.

Further, said grinding roller axle of the utility model and grinding roller contact site diameter are maximum.

The beneficial effect of the utility model is:

1, it is about 35% that this invention has reduced the weight of single new grinding roller, and do not influence result of use, and the waste of material situation is able to effective solution in the time of use, through calculating, following correction data is arranged:

2, maintenance is more sliding simple relatively, needn't re-use very big hydraulic test and operate, and directly with oxygen-acetylene cutter grinding roller is easily cut off, and grinding roller thickness that after all should breakage is 20mm only;

3, consider from the angle of transportation, smelting, can reduce social freight volume and smelting amount greatly, meet the national policy of energy-saving and emission-reduction.

Description of drawings

Fig. 1 is the structural representation of a kind of novel grinding roller assembly of the utility model.

The specific embodiment

With reference to Fig. 1; The described a kind of novel grinding roller assembly of the utility model comprises bearing assembly chamber 1, grinding roller axle 2, grinding roller 3, grinding roller axle top nut 4, floor clip 5 and grinding roller axle lower nut 6, and grinding roller axle 2 runs through whole grinding roller assembly; Bearing assembly chamber 1 is arranged on the upper end of grinding roller axle 2; Grinding roller 3 is installed in the lower end of grinding roller axle 2, and grinding roller axle 2 lower ends are provided with grinding roller axle top nut 4 and grinding roller axle lower nut 6, are provided with floor clip 5 between grinding roller axle top nut 4 and the grinding roller axle lower nut 6; Grinding roller 3 external diameter 400mm, characteristics are that the internal diameter of said grinding roller 3 is 260mm; The diameter of said grinding roller axle 2 and said grinding roller 3 connecting portions is 260mm.

Further, the said grinding roller axle 2 of the utility model is maximum with grinding roller 3 contact site diameters.

The described content of this specification embodiment only is enumerating the way of realization of inventive concept; The protection domain of the utility model should not be regarded as and only limit to the concrete form that embodiment states, the protection domain of the utility model also based on those skilled in the art according to the utility model design the equivalent technologies means that can expect.
