Abstract
The utility model provides a tipper riding wheel labyrinth seals, belongs to tipper riding wheel sealing technique field for effectively reduce inside coal dust etc. Gets into the riding wheel, cause the riding wheel lubricated bad, bearing failure, its technical scheme is: increased the ring packing groove on the circumference lateral wall of end cover, the ring packing grooved ring flushes with the up end plane of casing around the circumference of end cover, the lower limb in ring packing groove, and the ring packing inslot has inlayed annular felt ring. The utility model discloses radial ring packing groove and felt ring have been increased at the end cover circumference, labyrinth seals after the improvement becomes axial and radial mixing maze, the labyrinth seals clearance is littleer, the length and the direction in maze all have the increase, make dustproof effect improve greatly, can prevent effectively that the coal dust from getting into inside the bearing, improve the lubrication of bearing, the lubricated cycle has been prolonged, the service life of the bearing is prolonged, thereby the number of times that the riding wheel more encircled has been reduced, the life of riding wheel has been prolonged, the shut -down number of times that brings because of riding wheel bearing failure has been reduced, the production efficiency is raised.
Description
Technical field
The utility model relates to a kind of wagon tipper support roller labyrinth seal of improvement, belongs to wagon tipper support roller technical field of sealing technology.
Background technique
Wagon tipper is a kind of heavy mechanical equipment being used for dumping truck bulk cargo, rotor type dumper riding wheel apparatus has supported weight and leading role, end ring support roller station system forms by four and forms being distributed in the flange roll shaft compensated on beam, always have 16 roll shafts, the diameter of roll shaft is 800 millimeters.Four rolling assemblies are arranged on two prefabricated metal beams, and two beams of metals are fixed on across on the geotechnological beam on hopper machine hole.Wagon tipper has 8 groups of support rollers, and the bearing of support roller adopts rolling bearing, and lubrication system adopts labyrinth seal.
Riding wheel apparatus is arranged on below ground, be in the large and condition of humidity of dust to work, although existing labyrinth seal has certain dustproof effect, but coal dust is thinner, still entering Bearing inner than being easier to, causing bearing well not lubricate, reduce the working life of bearing, and easily cause the damage of bearing and miscellaneous part, affect production of normally unloading.Therefore be necessary to improve the sealing means of existing bearing.
Model utility content
Technical problem to be solved in the utility model is the labyrinth seal of a kind of wagon tipper support roller, and this sealing can effectively prevent tiny coal dust from entering the lubrication that Bearing inner affects bearing, improves bearing working life.
The technological scheme solved the problems of the technologies described above is:
The labyrinth seal of a kind of wagon tipper support roller, it comprises end cap, oil sealing, end cap is connected with housing seal by oil sealing, its improvements are, the circumferential side wall of end cap adds annular seal groove, annular seal groove is around the circumference of end cap, and the lower limb of annular seal groove and the upper-end surface planes align of housing, annular seal groove is embedded with annular felt collar.
The labyrinth seal of above-mentioned wagon tipper support roller, described annular seal groove is the annular groove of 4mm × 4mm, and felt collar thickness is 3mm, and felt collar and seal groove two lateral extent 0.5mm, be 1mm with seal groove distance from bottom, annular seal groove and felt collar form labyrinth seal.
The beneficial effects of the utility model are:
The utility model adds radial annular seal groove and felt collar at end cap circumference, after improvement labyrinth seal become axially and radial mixing labyrinth, labyrinth seal clearance is less, all there is increase in length and the direction in labyrinth, dust-proof effect is improved greatly, can effectively prevent coal dust from entering Bearing inner, improve the lubrication of bearing, extend lubrication interval, improve working life of bearing, decrease the number of times of tugboat more ring, extend the working life of support roller, decrease because bearing of conveyor idler damages the shutdown times brought, thus improve manufacturing efficiency.The utility model has the lubrication circumstances that structure is simple, reasonable in design, maintaining facilitates, can observe bearing, is a kind of support roller sealing being applicable to rotor type dumper.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of end cap.
In figure, mark is as follows: end cap 1, straight Hudrodynamic lubrication mouth 2, oil sealing 3, housing 4, felt collar 5, annular seal groove 6.
Embodiment
The utility model improves on the basis of original end cap 1, oil sealing 3 and labyrinth seal.
Show in figure, to get on the bus out annular groove at the circumferential side wall of end cap 1, annular groove is annular seal groove 6, and annular seal groove 6 is around the circumference of end cap 1, and the lower limb of annular seal groove 6 and housing 4 upper-end surface planes align, annular seal groove 6 is embedded with annular felt collar 5.
Show in figure, annular seal groove 6 is the annular groove of 4mm × 4mm, and felt collar 5 thickness is 3mm, and two lateral extent 0.5mm of felt collar 5 and seal groove 6 are 1mm with the distance from bottom of seal groove 6.And former sealing labyrinth minimum clearance is 1.5mm, the labyrinth seal clearance after improvement is less.
The utility model forms radial labyrinth by felt collar 5 with the annular seal groove 6 of end cap 1 and seals.After improvement labyrinth seal become axially and radial mixing labyrinth, labyrinth seal clearance is less, and all there is increase in length and the direction in labyrinth, and dust-proof effect is improved greatly, can effectively prevent coal dust from entering Bearing inner.
