Abstract
The utility model relates to an adjustable sealing structure of a mining grinding main bearing. The adjustable sealing structure comprises seal rubber, a pressing plate, a compressing spring, a pressing ring, an oil cup, a triangular block, a compressing bolt and a fixed bolt, wherein the seal rubber is contacted with an inclined surface of the triangular block fixed on a bearing base and a bearing cover and is closely contacted with a hollow shaft; the compressing spring is hooked on the fixed bolt fixed on the bearing base and the bearing cover, the pressing ring arranged on the upper surface of the seal rubber is compressed, meanwhile, the end surface of the pressing plate is utilized to compress, and a condition that the seal rubber is compressed is realized. The adjustable sealing structure provided by the utility model effectively solves the problem that a bearing seal is easy to wear, the effective compensation is not obtained, and the oil leakage is easy to appear; compared with the existing sealing structure, the adjustable sealing structure of the mining grinding main bearing is relatively complex, and part manufacture accuracy and assembling requirement are high.
Description
Technical field
The utility model relates to a kind of sealing configuration, the adjustable sealing configuration of especially mining mill main bearing.
Background technique
Most bearing seal adopts the end face rubber seal of end face J type spring end face rubber seal or many lips multiple-grooved, this type of is sealed in can realize bearing seal to a certain extent, but due in use, due to the installation precision of grinding machine, the reasons such as the vibrations of grinding machine, bearing seal can not realize tight seal, simultaneously easy quick-wearing excessively, and can not effectively be compensated, easily there is leakage of oil, both befouling environment, causes again economic loss.
Model utility content
In order to overcome above-mentioned deficiency of the prior art, solve the compensation problem after main shaft seals wearing and tearing, reduce the too fast wear problem of Sealing, prevent sealing place leakage of oil.The utility model proposes a kind of new solution.
The adjustable sealing configuration of a kind of mining mill main bearing, described structure comprises caulking gum, pressing plate, holddown spring, trim ring, lubricating cup, corner block, hold-down bolt and fixing bolt, described caulking gum be fixed on bearing support and contact with the described corner block inclined-plane on bearing cap, with quill shaft close contact, described holddown spring is hooked on the described fixing bolt that is fixed on bearing support and bearing cap, compresses the trim ring of described caulking gum upper surface, simultaneously, utilize the end face of described pressing plate to compress, realize press seal rubber.
Wherein, between described caulking gum, be by the location of fixing double inclined plane corner block, prevent relatively rotating of Sealing and trim ring and pressing plate, reduce the wearing and tearing of Sealing, under pressing force of the spring effect, the Sealing contacting with described corner block double inclined plane can move down, with quill shaft close contact, realize the compensation after wearing and tearing, prevent oil leak.
Wherein, on Sealing, be provided with grease channel, make lubricant grease enter the surface of contact of caulking gum and quill shaft by described lubricating cup, reduce the wearing and tearing of described Sealing.
Brief description of the drawings
Fig. 1 is the adjustable sealed structural representation of the mining mill main bearing of the utility model.
Fig. 2 is that Fig. 1 is along A-A directional profile figure.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As Fig. 1,2, the adjustable sealing of mining mill main bearing mainly comprises caulking gum 1, pressing plate 2, holddown spring 3, trim ring 4, lubricating cup 5, corner block 6, hold-down bolt 7 and fixing bolt 8.Caulking gum be fixed on bearing support 9 and contact with the corner block inclined-plane on bearing cap, with quill shaft 10 close contacts, holddown spring 3 is hooked on the fixing bolt 8 that is fixed on bearing support 9 and bearing cap, the trim ring 4 of press seal rubber 1 upper surface, simultaneously, utilize the end face of pressing plate 2 to compress, realize press seal rubber 1.
Owing to being by the location of fixing double inclined plane corner block 6 between caulking gum 1, prevent relatively rotating of Sealing and trim ring 4 and pressing plate 2, reduce the wearing and tearing of Sealing, under pressing force of the spring effect, the Sealing contacting with corner block 6 double inclined planes can move down, with quill shaft 10 close contacts, realize the compensation after wearing and tearing, prevent oil leak; On the other hand, on Sealing, be designed with grease channel, make lubricant grease enter the surface of contact of Sealing and quill shaft 10 by lubricating cup 5, reduce the wearing and tearing of Sealing.
The utility model has effectively solved the easy quick-wearing excessively of former bearing seal, and can not effectively be compensated, and easily occurs the problem of leakage of oil.But, compared with sealing configuration in the past, the adjustable sealing configuration relative complex of mining mill main bearing, part make precision and matching requirements relatively high.
The above is only the utility model preferred implementation; should be understood that; for the member of ordinary skill of the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
Claims (3)
