Abstract
The utility model relates to a grinding roller positioning device of a vertical mill. The grinding roller positioning device comprises a roller shaft, a rocker arm, a front bearing, a rear bearing and a grinding roller, wherein the grinding roller and the roller shaft are assembled to form an integrated body; the roller shaft and the grinding roller can rotate together; the front bearing and the rear bearing are located between the roller shaft and the inner cavity of the rocker arm. The grinding roller and the roller shaft are assembled to form the integrated body so that the inner structure of the grinding roller is simplified; meanwhile, the assembling and the maintenance are very convenient; the front bearing and the rear bearing are mounted in the inner cavity of the rocker arm, so that the installation, detachment and maintenance of the bearings are very convenient. The front bearing and the rear bearing are sliding bearings. The self-lubricating sliding bearings are adopted and a special lubricating system does not need to be arranged, so that the structure of the grinding roller positioning device is further simplified.
Description
Technical field
The utility model relates to a kind of Vertical Mill technical field, relates in particular to a kind of grinding roller positioner.
Background technology
Current, in cement plant and steel mill's grinding system, 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 needs to be equipped with special bearing lubrication system; Grinding roller is transferred roll shaft and is not turned, and grinding roller internal structure is complexity comparatively, and rolling bearing assembling is also comparatively difficult with maintenance replacing.
Utility model content
Provide one can simplify assembling process for above problem the utility model, bearing maintenance is changed more convenient, simplifies the grinding roller of vertical mill positioner of grinding roller internal structure.
Provide a kind of grinding roller of vertical mill positioner in order to overcome the above problems the utility model, comprise roll shaft, rocking arm, fore bearing, rear bearing, grinding roller, it is characterized in that: grinding roller and roll shaft assembling are as a whole, roll shaft and grinding roller can together with rotate, fore bearing and rear bearing are between roll shaft and rocking arm inner chamber.Grinding roller and roll shaft assembling are as a whole, can make grinding roller internal structure simplify, and its assembling is also more convenient with maintenance simultaneously; The installation site of fore bearing and rear bearing is at rocking arm inner chamber, and bearing installation and removal maintenance is also more convenient.
Described fore bearing and rear bearing are all sliding bearing.Adopt self-lubricating plain bearing, without being equipped with special lubricating system, further simplified the structure of grinding roller positioner.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
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 positioner, comprise roll shaft 1, rocking arm 2, fore bearing 3, rear bearing 4, grinding roller 5, grinding roller 5 assembles as a whole with roll shaft 1, roll shaft 1 and grinding roller 5 can together with rotate, fore bearing 3 and rear bearing 4 are between roll shaft 1 and rocking arm 2 inner chambers.Described fore bearing 3 is all sliding bearing with rear bearing 4.
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.
