Abstract
The utility model relates to a sealing device suitable for a main shaft bearing of a large-size ball grinding mill. The sealing device comprises a bearing cover, a hollow shaft, a rubber asbestos packing and a packing pressing cover, wherein the rubber asbestos packing is arranged between the outer side of the bearing cover and the hollow shaft, and the packing pressing cover is arranged outside the rubber asbestos packing and is connected with the bearing cover; and a groove matched with the rubber asbestos packing is formed in the outer side of the bearing cover. According to the sealing device, the sealing effect is good, the service life of the bearing is prolonged, and the installation is simple and convenient.
Description
Technical field
The utility model relates to the machinery field, relates in particular to the seal arrangement that is applicable to the large-size ball mill main shaft bearing.
Background technique
The seal type of bearing keeps good lubricating condition and normal working environment in order to make bearing, give full play to the service behaviour of bearing, increase the service life, must have suitable sealing, with the leakage that prevents oiling agent and the intrusion of dust, aqueous vapor or other dirts rolling bearing.
At present, the sealing of large-size ball mill main shaft bearing is difficulty relatively, uses wool felt to seal usually, but sealing effect is undesirable, and this sealing is because friction is bigger at work, and heating value is also big, easily cause insufficient lubrication, the easy abrasion of surface of contact, thus cause sealing effect and decreased performance.
The model utility content
The technical problems to be solved in the utility model provides the seal arrangement that is applicable to the large-size ball mill main shaft bearing, good sealing effect, simple installation.
For solving the problems of the technologies described above, the utility model provides the seal arrangement that is applicable to the large-size ball mill main shaft bearing, comprise bearing cap and quill shaft, seal arrangement also comprises the rubber asbestos packing that is arranged between the bearing cap outside and the quill shaft, the packing gland that is arranged on rubber asbestos packing outside and is connected with bearing cap; The arranged outside of bearing cap has the groove that is complementary with the rubber asbestos packing.
Optionally, packing gland is fixedlyed connected with bearing cap by clamping bolt.
Compared with prior art, the utility model is provided with the rubber asbestos packing, makes sealing effect have and significantly improves, and simple installation has prolonged working life of bearing, has saved cost of production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model is applicable to the seal arrangement of large-size ball mill main shaft bearing, comprise bearing cap 1 and quill shaft 4, seal arrangement also comprises the rubber asbestos packing 2 that is arranged between bearing cap 1 outside and the quill shaft 4, the packing gland 3 that is arranged on rubber asbestos packing 2 outsides and is connected with bearing cap 1; The arranged outside of bearing cap 1 has the groove that is complementary with rubber asbestos packing 2.Packing gland 3 is fixedlyed connected with bearing cap 1 by clamping bolt.
Arranged outside one groove and a brill silk hole at bearing cap 1; Make a steel plate packing gland 3 again, and boring, make the hole of packing gland 3 and the silk hole on the bearing cap 1 be complementary.During assembling, after earlier rubber asbestos packing 2 usefulness machine oil being soaked, be placed in the groove in the bearing cap 1 via hole outside, with hex head bolt packing gland 3 be fixed on bearing cap 1 outside again, it is too tight to make that rubber asbestos packing 2 is not pressed.The bearing cap 1 of macropore is positioned on the big step of pebble mill quill shaft by direction, adorns bearing and bearing support then, last, bearings at both ends lid 1 is loaded onto, just finished the sealing of large-size ball mill main shaft bearing.After using a period of time to treat the wearing and tearing of rubber asbestos packing, again the hex head bolt on the packing gland is tightly once got final product.The rubber asbestos packing is an easily damaged parts, when wearing and tearing can not be used, even want to change, changes also more convenient.
The rubber asbestos packing of the utility model by being provided with improved sealing effect, and simple installation, saves production cost.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
