Abstract
The utility model relates to a grinding roller assembly structure for a vertical mill. The grinding roller assembly structure comprises a roller shaft, a rocker arm, a front bearing, a shaft sleeve, a rear bearing and a grinding roller, wherein the grinding roller and the roller shaft are assembled into a whole; the front and rear bearings are mounted between the roller shaft and the inner cavity of the rocker arm; the shaft sleeve is mounted between the front and rear bearings; the front and rear bearings are both rolling bearings. According to the grinding roller assembly structure, the grinding roller and the roller shaft are assembled into a whole, and rotate together, so that the inner structure of the grinding roller is simplified, and meanwhile, the grinding roller is more convenient to mount and maintain; the rolling bearings are mounted in the inner cavity of the rocker arm, so that the bearings can be convenient to mount, dismount and maintain.
Description
Technical field
The utility model relates to a kind of Vertical Mill technical field, relates in particular to a kind of grinding roller assembly structure.
Background technology
Current, in the grinding system of cement plant and steel mill, Vertical Mill, as a kind of main milling equipment, is widely used the occasions such as grinding raw material, cement, coal dust, slag and slag.Vertical Mill has stable mechanism performance, higher abrasive efficiency and longer life-span.Grinding roller is as one of Vertical Mill core component, with the carrier of milling of mill formation Vertical Mill.The rolling bearing of most Vertical Mill is mounted in grinding roller inside, and grinding roller is transferred roll shaft and do not turned, and grinding roller internal structure and rolling bearing assembling process are comparatively complicated, and comparatively difficulty is changed also in maintenance.
Utility model content
Provide one rolling bearing can be installed in rocking arm chamber for above problem the utility model, simplified assembling process, bearing maintenance is changed more convenient; Simplify grinding roller internal structure, make grinding roller and roll shaft be connected into as a whole a kind of grinding roller of vertical mill assembly structure
Provide a kind of grinding roller of vertical mill assembly structure in order to overcome the above problems the utility model, comprise roll shaft, rocking arm, fore bearing, axle sleeve, rear bearing, grinding roller, it is characterized in that: grinding roller and roll shaft assembling are as a whole, fore bearing and rear bearing are arranged between roll shaft and rocking arm inner chamber, between fore bearing, rear bearing, axle sleeve is housed, fore bearing and rear bearing are all rolling bearing.
Grinding roller and roll shaft assembling are as a whole, and grinding roller rotates together with roll shaft, and grinding roller internal structure is simplified, and it installs with maintenance also more convenient simultaneously; The installation site of rolling bearing is at rocking arm inner chamber, and bearing installation and removal maintenance is also more convenient.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
In Fig. 1: 1-roll shaft; 2-rocking arm; 3-fore bearing; 4-axle sleeve; 5-rear bearing; 6-grinding roller.
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1 and Figure 2, the utility model provides a kind of grinding roller of vertical mill assembly structure, comprise roll shaft 1, rocking arm 2, fore bearing 3, axle sleeve 4, rear bearing 5, grinding roller 6, grinding roller 6 assembles as a whole with roll shaft 1, fore bearing 3 and rear bearing 5 are arranged between roll shaft 1 and rocking arm 2 inner chambers, between fore bearing 3, rear bearing 5, axle sleeve 4 is housed, fore bearing 3 and rear bearing 5 are all rolling bearing.
When Vertical Mill operation, grinding roller 6 rotates by the fore bearing 3 that is positioned at rocking arm 2 chambeies with roll shaft 1 together with rear bearing 5.
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 amendment of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
