Abstract
The utility model belongs to a sealing element for a rotation shaft, especially refers to a float oil-seal ring in sealing of moving structure for a large engineering machinery, including oil-seal ring body which is characterized in that one side of the oil-sealing ring body is provided with a sealed ring of a width for 0.7+-0.2mm. The utility model has such salutary effects that it is suitable for sealing the moving structure of large engineering machinery, and has longest longevity and improved sealing property for selecting the optimal width for the sealing ring.
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
Large-scale engineering machinery, sealing adopts float grease seal ring to play the effect of sealing as travellers such as bulldozer, coal winning machine, excavators.Mounting structure is that two float grease seal rings are installed in respectively in two oil sealing bases at present, and an oil seal ring rotates in the using process, and another is static.Float grease seal ring is to realize sealing by the seal band on the one side end face.The width of seal band directly influences the float grease seal ring life-span, the width of seal band is too wide, lubricating condition worsens the fast of oily temperature rise when float grease seal ring relatively rotates, the easy coking of oil machine, metal particle under grinding is with the sealing strip galled spots, frictional force is increased cause sealing surfaces to damage, cause that two encircle extremely; In use because one of float grease seal ring is static, another uses that be rotatably assorted, oil seal ring can fluctuate, again because of foozle own, so require seal band that certain width must be arranged.If it is too narrow, can cause leakage of oil equally.The width of optimal seal endless belt is the technical problem that those skilled in the art need to be resolved hurrily.
The model utility content
The purpose of this utility model is to provide a kind of float grease seal ring of suitable large-scale engineering machinery traveller sealing usefulness, has selected the width of optimal seal endless belt, makes its longest-lived.
The utility model for achieving the above object, by the following technical solutions: a kind of float grease seal ring, comprise the oil sealing ring body, it is characterized in that: a side end face of described oil sealing ring body is provided with the seal band that width is 0.7 ± 0.2mm.
Described seal band width is 0.7mm.
The beneficial effects of the utility model: be fit to the float grease seal ring of large-scale engineering machinery traveller sealing usefulness, selected the width of optimal seal endless belt, make its longest-lived, sealability improves.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode structural representation.
Embodiment
As shown in the figure, a kind of float grease seal ring, the oil sealing ring body 3 that adopts the high alloy special cast iron to make, a side end face of described oil sealing ring body is provided with the seal band 3-1 that width is 0.7 ± 0.2mm.Production experimental results show that: the seal band of width 0.7mm is an optimum width.During use, be installed in two relative float grease seal rings in the oil sealing base 4 respectively and be socketed on the transmission shaft 5, rubber seal 2 is equipped with in the outside, the oil sealing ring body back side, and oil sealing base refills in traveller seat 1.Float grease seal ring is to realize sealing by the seal band 3-1 on the one side end face.Must guarantee suitable tolerance when float grease seal ring manufacturing and assembling.
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 kind of float grease seal ring comprises the oil sealing ring body, it is characterized in that: a side end face of described oil sealing ring body is provided with the seal band that width is 0.7 ± 0.2mm.
2, float grease seal ring according to claim 1 is characterized in that: described seal band width is 0.7mm.
