Abstract
The utility model discloses a mill equipment in the industry of building materials and particularly relates to a supporting structure of a vertical mill tray. The supporting structure can improve stability and supporting capacity of the mill tray in the operation. The structure comprises the mill tray and a large open tooth ring fixed at the outer circle of an annular shell of the mill tray. An annular seat is fixedly arranged on the foundation and the mill tray can be supported on the annular seat in a rotatable manner by a hydrostatic bearing with large diameter; and the rotating center of the mill tray is limited by a centering device. As the independent hydrostatic bearing is used for supporting the mill tray, the vertical loading capacity of the mill tray can be improved and the capacity of shock absorption and damping capacity can also be effectively improved with the increase in supporting diameter, thereby greatly improving the operation stability and bearing capacity of the mill tray. Therefore, the supporting structure can be widely applied to the modification of existing vertical mills and the manufacturing of new products.
Description
Technical field
The utility model relates to the milling equipment that uses in a kind of building materials industry, especially relates to a kind of supporting structure of Vertical Mill mill.
Background technology
Vertical Mill is to use a kind of very widely milling equipment in the building materials industry, and it mainly carries out grinding, oven dry, sorting to cement slurry, grog and slag etc.In present traditional Vertical Mill both domestic and external, high pressure lubricating pad in speed reducer dedicated supports by Vertical Mill in the supporting of mill, diameter can not be done very big owing to speed reducer dedicated, this just makes the actual supporting diameter of mill very little (the lubricating pad distribution circle often grinding roller roll a little in), therefore cause mill galloping, vibration greatly, and then cause the bigger vibration of Vertical Mill complete machine; The downforce of Vertical Mill grinding roller is strengthened be restricted, the kind of Vertical Mill grinding material is also corresponding to be subjected to certain restriction.In addition, because the speed reducer dedicated design of the high-power Vertical Mill of China and manufacturing technology are immature, mainly solve by import, the speed reducer dedicated price of high-power Vertical Mill is very high, makes the cost of large-scale Vertical Mill very high, and this has also limited the maximization and the production domesticization of China's Vertical Mill.
The utility model content
Technical problem to be solved in the utility model provides the supporting structure of the Vertical Mill mill of a kind of stationarity that improves mill running and bearing capacity.
The technical scheme that its technical problem that solves the utility model adopts is: the supporting structure of Vertical Mill mill, comprise mill and be fixed on open type bull gear on the excircle of annular outer cover body of mill, it is characterized in that: be set with annular seating on the basis, mill is supported on the annular seating by the major diameter hydrostatic bearing is rotatable, and the pivot of mill is spacing by centring means.Utilize this independently supporting of major diameter hydrostatic bearing, can effectively strengthen the diameter of mill supporting, the support unit of mill and the transferring elements of motion are relatively independent, thereby have improved the stationarity and the bearing capacity of mill running significantly.
For make mill turn round more steadily and bearing capacity stronger, the end face of the annular outer cover body of mill can be supported on the major diameter hydrostatic bearing, thereby make mill support the diameter maximum.
The beneficial effects of the utility model are: the major diameter hydrostatic bearing supports mill owing to adopt independently, not only can improve the ability of the vertical load of bearing mill, simultaneously owing to support the increasing of diameter, also can effectively improve shock-absorbing, cushioning ability, thereby improved the stationarity and the bearing capacity of mill running significantly, can be widely used in the manufacturing of the transformation of existing Vertical Mill and new product.
Description of drawings
Fig. 1 is mill transmission and supporting structure figure in the Vertical Mill of the present utility model.
Fig. 2 is the partial enlarged drawing of mill supporting in M place among Fig. 1.
Fig. 3 is along the partial sectional view of A-A direction mill among Fig. 1.
Be labeled as among the figure: main motor 1, transmission synchronizing shaft 2, decelerator 3, open type pinion 4, open type bull gear 5, mill 6, centring means 7, pressurization oil cylinder 8, grinding roller 9, major diameter hydrostatic bearing 10, annular seating 11, labyrinth type oil groove 12, inner chamber 13.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1-Figure 3, main motor 1 is by transmission synchronizing shaft 2 transmission universal speed reducers 3, be set with open type pinion 4 on the output shaft of decelerator 3, the open type bull gear 5 on the excircle of open type pinion 4 and the annular outer cover body that is fixed on mill 6 meshes, and rotates thereby drive mill 6.Above-mentioned power transmission is identical with traditional Vertical Mill with structure.Fixedly install annular seating 11 on the basis, as independent support, mill 6 is by major diameter hydrostatic bearing 10 rotatable being supported on the annular seating 11.Owing to can produce the radial load of horizontal direction during the exposed gear engagement, move horizontally for preventing mill 6, centring means 7 is set separately, the pivot of mill 6 is spacing by centring means 7.
Centring means 7 can adopt multiple version to realize, for example centripetal limb support structure, central shaft location structure etc., these all are prior aries, and those skilled in the art can adopt the usual version that adopts of mechanical field to realize according to actual conditions, repeat no more here.
Support diameter in order to strengthen to greatest extent, the end face of the annular outer cover body of mill 6 is supported on the major diameter hydrostatic bearing 10.
For the ease of major diameter hydrostatic bearing 10 is installed, also consider the fuel feeding and the oil return problem of major diameter hydrostatic bearing 10 simultaneously, the end face of annular seating 11 is provided with the inner chamber 13 of annular, and major diameter hydrostatic bearing 10 is arranged in the inner chamber 13 of annular seating 11.Like this, the inner chamber 13 of the annular on the end face of annular seating 11 both can be used as the cavity that major diameter hydrostatic bearing 10 is installed, and also the inner chamber 13 of annular seating 11 can be communicated with drainback passage simultaneously, helped the processing of oil return.In addition, the end face of the inside and outside both sides of end face that is positioned at the annular outer cover body of mill 6 on the annular seating 11 is provided with labyrinth type oil groove 12, labyrinth type oil groove 12 and be fixed between the parts on the annular outer cover body of mill 6 and can form labyrinth sealing.
