Abstract
The utility model relates to a flexible metal sealing ring, which is composed of flexible metal blocks and a spring. The utility model is characterized in that both ends of the flexible metal block are inclined planes; the inclined angle alpha of the inclined plane is 65 DGR-75 DGR; four to six flexible metal blocks are mutually connected; the spring is sheathed in spring slots on the surfaces of the flexible metal blocks; a flexible metal sealing ring is formed. Because the sealing ring is made of flexible metal materials, the hardness of the sealing ring is lower than the hardness of a dual shaft, and the dual shaft can not be damaged. The utility model has the advantages of convenient installation and maintenance, long service life, large applicable temperature interval, and a great amount of oil materials saving.
Description
The utility model is to belong to the seal arrangement that is used on the running shaft.
Spindle nose at the input of oil-field oil pumper speed reducer, output shaft seals at present, the sealing of sealing of machine oil recovery well well head and screw pump is generally all with rubber and felt sealing, especially in cold winter, time is long, rubber ring is aging, and it leaks serious, often causes the body inner oil shortage, and pollution housing, the gear oil consume is many, and waste is serious, influences work.
The purpose of this utility model is to propose a kind of soft metal seal ring, makes the soft metal piece with iron charge, graphite after bonding, connects with spring, forms the soft metal seal ring, not only can guarantee sealing effect, and easy to maintenance, reduces labor intensity the saving oil plant.
The utility model is made up of soft metal piece 1, spring 2, as shown in Figure 1, 2; It is characterized in that: piece 1 two ends in soft metal are the inclined-plane, and its angle of tilt α is 65 °-75 °, and 4-6 piece soft metal piece 1 links, and are placed in the lip-deep spring groove of each soft metal piece with spring 2, form the soft metal seal ring.
The utility model is because the housing of seal ring is to be made of polylith soft metal piece 1, and the both ends of the surface of whenever determining are the inclined-planes, its angle [alpha] is the 65-75 degree, and soft metal piece 1 can be four, six, on each piece surface spring groove is arranged, be placed in spring 2, under the effect of spring force, will dwindle endoporus along sliding in the α angle, reach with idol axle and be slidingly matched, play the effect of sealing without leakage.
The utility model has following advantage compared with prior art: because this seal ring is made up of polylith soft metal piece 1 and spring 2, and every two ends are inclined-planes, its angle α is 65 °-75 °, when the long-term rotation of axle and wear and tear, each soft metal piece 1 is under the effect of outer casing spring 2, and each is along sliding in the α angle, and ring inner hole dwindles, reaching is slidingly matched with the antithesis axle plays the effect of sealing without leakage, and the durable life-span is long.Each soft metal piece 1 is to mix with antifriction material (graphite) with iron powder to press refining, machine to add to form, have a large amount of gaps between the various material granules, boil through oil, promptly contain lubricant oil, and the hardness of hardness ratio antithesis axle is much lower, can not damage antithesis.These seal ring installation and maintenance are convenient and swift, four soft metals certainly can be fastened on the antithesis axle with spring 2, can advance in the chamber of body, and gland gets final product.The sealing circle is used for the input of oil-field oil pumper speed reducer, the spindle nose sealing of output shaft, compares long service life with existing seal ring, and the maintain and replace time is short, and the Applicable temperature scope is big, can save a large amount of machine oil.
Description of drawings:
Fig. 1 is the utility model plan view;
Fig. 2 is the utility model side view cutaway drawing.
Embodiment of the present utility model:
The utility model by the soft metal determine 1, spring 2 forms, as shown in Figure 1, 2; Its spring 2 can adopt selects part for use; Soft metal piece 2 usefulness pure iron powder, antifriction material such as graphite and cementin, iron powder is a main raw material, iron powder is 100 orders, content of graphite 8-13%, with iron powder, graphite and a small amount of cementin, add and form through mixing compacting, machine, wherein angle of tilt α of every each end of soft metal piece is between 65 degree-75 degree, and there is spring groove on each piece surface.
With 4, also can be combined into circle by 6 soft metal pieces 1, and be enclosed within on each soft metal piece 1 with spring 2, form the soft metal seal ring.
Claims (1)
1, a kind of soft metal seal ring comprises spring, and it is characterized in that: soft metal piece (1) two ends are the inclined-plane, its angle of tilt α is 65 °-75 °, 4-6 piece soft metal piece (1) links, and is placed in the lip-deep spring groove of each soft metal piece with spring (2), forms the soft metal seal ring.
