Abstract
The utility model relates to a sealing element, in particular to a combined sealing ring. The combined sealing ring is characterized in that the combined sealing ring comprises an outer frame oil seal, an intermediate frame oil seal and an inner frame oil seal, which are mutually combined to form a labyrinth type structure; lubricating grease layers are arranged among more than two sealing lips; and a distance-adjustable moving space structure is formed between a contacted surface A of the outer frame oil seal and the intermediate frame oil seal, and a contacted surface B of the inner frame oil seal and the intermediate frame oil seal. In the combined sealing ring disclosed by the utility model, a sealing structure is ingeniously designed and the quantity of the sealing lips is reasonably configured, so that an external medium can be better sealed and the better sealing performance can be obtained; and in addition, the full lubrication of the sealing lips can be maintained and the requirement for sealing of engineering machinery can be met.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of combined type packing ring.
Background technique
The Sealing of present engineering machinery, exist sealing configuration simple more, seal lip is less, to the dissatisfactory shortcoming of the sealing effect of external agency, for this reason, need a kind of sealing configuration ingenious, the sealing lip reasonable quantity, can better seal action be arranged to external agency, and can obtain the oil sealing of better sealability, satisfy the requirement of engineering machinery sealing with this.
The model utility content
A kind of combined type packing ring of the present utility model, by ingenious design to sealing configuration, and to the reasonable disposition of sealing lip quantity, can better seal action be arranged to external agency, and can obtain better sealability, and the sufficient lubrication that can keep sealing lip, can satisfy the requirement of engineering machinery sealing.
The technological scheme that the utility model adopted is:
A kind of combined type packing ring is characterized in that: comprise being combined to form the outer skeleton oil sealing of maze-type structure, middle outside framework oil seal and inner frame oil sealing mutually.
Described combined type packing ring, the quantity of sealing lip are more than two.
Described combined type packing ring is filled with grease layer between the sealing lip.
Described combined type packing ring, the surface of contact A face of outer skeleton oil sealing and middle outside framework oil seal is with the activity space structure that forms adjustable distance between the surface of contact B face of inner frame oil sealing and middle outside framework oil seal.
Like this when work, a kind of combined type packing ring of the present utility model, be combined to form the outer skeleton oil sealing of maze-type structure, middle outside framework oil seal and inner frame oil sealing mutually, the quantity of sealing lip is more than two, thereby realize many sealing lip sealings and maze-type structure, external agency is had better seal action; Be filled with grease layer between the sealing lip, thereby keep lubricating sealing lip; The surface of contact A face of outer skeleton oil sealing and middle outside framework oil seal is with the activity space structure that forms adjustable distance between the surface of contact B face of inner frame oil sealing and middle outside framework oil seal, thereby can obtain better sealability,
A kind of combined type packing ring of the present utility model, by ingenious design to sealing configuration, and to the reasonable disposition of sealing lip quantity, can better seal action be arranged to external agency, and can obtain better sealability, and the sufficient lubrication that can keep sealing lip, can satisfy the requirement of engineering machinery sealing.

Embodiment
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, wherein Fig. 1 and Fig. 2 are original oil seal structure schematic representation, oil sealing comprises outer skeleton oil sealing 10 and inner frame oil sealing 12, and oil sealing is provided with four sealing lips, and it exists sealing configuration simple, seal lip is less, to the dissatisfactory shortcoming of the sealing effect of external agency.Fig. 3 is a kind of combined type packing ring structural representation of the present utility model, comprises the outer skeleton oil sealing 10, middle outside framework oil seal 11 and the inner frame oil sealing 12 that are combined to form maze-type structure mutually; Sealing lip 1-9, its quantity is nine; Be filled with grease layer between the sealing lip 1-9; The surface of contact A face 13 of outer skeleton oil sealing 10 and middle outside framework oil seal 11 is with the activity space structure that forms adjustable distance between the surface of contact B face 14 of inner frame oil sealing 12 and middle outside framework oil seal 11.
Like this when work, a kind of combined type packing ring of the present utility model, be combined to form outer skeleton oil sealing 10, middle outside framework oil seal 11 and the inner frame oil sealing 12 of maze-type structure mutually, the quantity of sealing lip 1-9 is nine, thereby realize many sealing lip sealings and maze-type structure, external agency is had better seal action; Be filled with grease layer between the sealing lip 1-9, thereby keep lubricating sealing lip 1-9; The surface of contact A face 13 of outer skeleton oil sealing 10 and middle outside framework oil seal 11 is with the activity space structure that forms adjustable distance between the surface of contact B face 14 of inner frame oil sealing 12 and middle outside framework oil seal 11, thereby can obtain better sealability,
A kind of combined type packing ring of the present utility model, by ingenious design to sealing configuration, and to the reasonable disposition of sealing lip quantity, can better seal action be arranged to external agency, and can obtain better sealability, and the sufficient lubrication that can keep sealing lip, can satisfy the requirement of engineering machinery sealing.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
