Abstract
The utility model belongs to a sealing element of an axis of swivel, and in particular relates to a floating oil-seal ring used for sealing mechanical running mechanisms of large works. The utility model comprises an oil-seal ring body and a sealing annular belt arranged on one end face of the oil-seal ring body. The utility model is characterized in that an annular pyramidal face of the oil-seal ring is provided with a rough layer of different rough lines. The utility model has the advantages of the floating oil-seal ring used for sealing mechanical running mechanisms of large works ensures the optimum roughness of the pyramidal face of the floating oil-seal ring, and can keep the friction of the O-shaped seal ring in the optimum state to achieve excellent sealing effect.
Description
Technical field
The utility model belongs to a kind of seal element of rotating shaft, relates in particular to a kind of large-scale engineering machinery traveller sealing float grease seal ring.
Background technique
The sealing of travellers such as large-scale engineering machinery such as bulldozer, stirrer, coal mine machinery adopts float grease seal ring to play the effect of seal lubrication.Mounting structure is that two float grease seal rings are installed in respectively in the oil sealing base at present, and oil sealing base refills in traveller.One of them rotates two oil sealing bases with axle, and another is fixed on the frame.Two float grease seal rings also with it correspondence be divided into rotating ring with fixed ring and relative revolution and tightly contacting, float grease seal ring and " O " shape seal ring are realized good sealing effect at the surface of contact of oil sealing base complete sealing surface of formation jointly.Float grease seal ring is given its certain axial pressure in when assembling, with the sealing that keeps float grease seal ring with can guarantee that float grease seal ring is relative and turn round.If pressure is excessive, " O " shape seal ring can be pressed onto the dead point, then reduces the working life of float grease seal ring greatly; If pressure is too small, can not satisfy above-mentioned two conditions again, do not have good seal action.Is wear-resistant according to the mine operating conditions to the requirement of oil sealing, can should be not less than 4000h in the operating time that peripheral velocity is not revealed under the operating conditions less than 0.3mpa less than 3m/S and oil pressure.Inventor's many years of experience finds that float grease seal annular conical surface roughened surface has determined that the frictional force size of " O " shape seal ring is one of its key that guarantees good seal performance.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of suitable large-scale engineering machinery traveller to seal the float grease seal ring of usefulness, guarantee the best roughness of float grease seal annular conical surface, can keep the frictional force of " O " shape seal ring to be in the optimum state, make it reach good sealing effect.
The utility model for achieving the above object, by the following technical solutions: a kind of float grease seal ring, comprise the seal band that is provided with on an oil sealing ring body and the side end face thereof, it is characterized in that: described oil sealing ring body circular cone is provided with the rough layer of different concavo-convex lines.
The roughness of described conical surface rough layer is Ra 6.3-12.5.
The beneficial effects of the utility model: the float grease seal ring that is fit to large-scale engineering machinery traveller sealing usefulness, guarantee the best roughness of float grease seal annular conical surface, can keep the frictional force of " O " shape seal ring to be in the optimum state, make it reach good sealing effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is to use the status architecture schematic representation.
Embodiment
As shown in the figure, a kind of float grease seal ring, the oil seal washer ring 1 that adopts the high alloy special cast iron to make, and the seal band 2 that is provided with on the one side end face, described oil sealing ring body circular cone is provided with the rough layer 3 of different concavo-convex lines, and the roughness of conical surface rough layer is best for Ra 6.3-12.5.During use, two relative float grease seal rings are installed in respectively in the oil sealing base 4, oil sealing base refills in traveller.Float grease seal annular conical surface rough layer roughness has determined that the frictional force size of " O " shape seal ring 5 is one of its keys that guarantee good seal performance.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. a float grease seal ring comprises the seal band that is provided with on an oil sealing ring body and the side end face thereof, it is characterized in that: described oil sealing ring body circular cone is provided with the rough layer of different concavo-convex lines.
