Abstract
The utility model belongs to the technical field of mine reducers, particularly to a novel mine reducer sealing structure. The novel mine reducer sealing structure aims at solving the problem that existing reducer sealing structures cannot effectively prevent pulverized coal particles from entering the collar portion of an oil seal and can affect the service life of the sealing structures. The novel mine reducer sealing structure comprises slots formed outside the oil seal and inside the end cap of a mine reducer, and a dustproof plate is arranged inside the slots, composed of two semi-circular shapes and fixed onto the end cap through bolts; an adjusting cushion which adjusts the position of the dustproof plate is arranged between the dustproof plate and the end cap, a gap exists between the dustproof plate and a shaft, and lubricating grease is filled between the space formed between the dustproof plate and the oil seal. By arranging an independent dustproof chamber outside the framework oil seal, the novel mine reducer sealing structure solves the problem that external dust enters the collar of the oil seal, avoids grain wearing of the oil seal, guarantees normal operation of the oil seal and effectively prolongs the normal service life of a reducer.
Description
Technical field
The utility model belongs to the technical field of mining speed reducer, is specifically related to a kind of new type mining speed reducer sealing configuration.
Background technique
Mining speed reducer is owing to operating mainly in coal industry, and applying working condition is severe, coal dust etc., and graininess dust is many.The contact seal of the main employing of current mining speed reducer sealing outside framework oil seal, because dust very easily enters lip, skeleton oil seal often produces abrasive wear and lost efficacy, so speed reducer oil leakage phenomenon frequently occurs, how to reduce and even avoid dust to invade oil seal lip, extend sealing life and just become an industry difficult problem.
Summary of the invention
The utility model cannot effectively stop pulverized coal particle to enter oil seal lip position in order to solve existing mining speed reducer sealing, affects the problem in sealing configuration life-span, proposes a kind of new type mining speed reducer sealing configuration.
The utility model adopts following technological scheme to realize:
A kind of new type mining speed reducer sealing configuration, comprise that mining speed reducer is positioned at the groove that the axial region of oil sealing outside, end cap inner side is opened, dust guard is set in groove, dust guard comprises two semicircles, dust guard is secured by bolts on end cap, the spacer of adjusting dust guard position is set between dust guard and end cap, and dust guard and between centers leave gap, form space and be full of lubricating grease between dust guard and oil sealing.
The utility model has increased independent dustproof room in outside framework oil seal outside, has solved the problem that external dust enters oil seal lip, has avoided the abrasive wear of oil sealing, has ensured the normal work of oil sealing, has effectively extended speed reducer up-time.Meanwhile, the utility model is simple, on existing structure, just can transform.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
Fig. 2 is anti-dust plate structure schematic diagram
In figure: 1-axle, 2-oil sealing, 3-dust guard, 4-lubricating grease, 5-spacer, 6-lubricating cup.
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described further.
New type mining speed reducer sealing configuration, comprise that mining speed reducer is positioned at the groove that the axial region of oil sealing outside, end cap inner side is opened, dust guard is set in groove, dust guard comprises two semicircles, dust guard is secured by bolts on end cap, the spacer of adjusting dust guard position is set between dust guard and end cap, and dust guard and between centers leave gap, form space and be full of lubricating grease between dust guard and oil sealing.
Implementation process is as follows: in the outside region of preventing dust of setting up of outside framework oil seal, by at axial region processing groove, and increase dust guard, dust guard is two semicircles, after assembling, embed in axial trough, and be secured by bolts on end cap, between dust guard and end cap, adjust dust guard position by spacer, ensure that dust guard and axle leave gap, avoid friction, between dust guard and oil sealing, form space and be full of lubricating grease, the object that reaches size particles thing simultaneously and all cannot enter oil seal lip, end caps is processed with grease channel repairing at any time.
