Description
Technical field
The present invention relates in a kind of machinery running shaft with bearing housing or gear box lubricating oil (fat) seal arrangement, specifically a kind of pair of split type combination oil seal.
Background technique
At present, the oil sealing on the market (like GB GB/T9877.1～9877.3--1998 defined), its profile is integral ring-shaped closing structure, this structural entity good seal performance, but installation and removal are comparatively difficult.When installation or removal; Other parts that must remove in the Seal cage outward turning rotating shaft could be advanced into oil sealing mounting point preset in the Seal cage or by opposite step and direction dismounting along an end of axle with oil sealing; Like this; Not only time-consuming taking a lot of work, and other parts that also might damage equipment when changing oil sealing have a strong impact on the efficient and the quality of the normal operation and the production of machinery.
In the actual mechanical process of device maintenance, the way of in case of emergency the unitized seal otch being used is arranged also.But misplace because of otch eventually and be difficult to the fixing location that reaches and to reach desirable sealing effect.
Split type oil sealing or the opening oil sealing released in the market, the material that has is soft excessively, the inconvenience location; The material that has is really up to the mark, and otch can't fit tightly; The perhaps better but difficult installation or cause costing an arm and a leg and to be used widely of material effect because of processing cost is too high.Such as disclosed patent document " make by oneself bit-type split type folder cloth oil sealing (ZL200720102538.9) " and the endless belt-shaped opening oil sealing of split type combine and assemble type (ZL200620023790.6) etc.; This type opening oil sealing still exists opening couplet (gluing) to connect difficulty and bonding precision is difficult to defectives such as assurance, influences sealing effect.
Summary of the invention
The objective of the invention is to the deficiency to existing technology, provide that a kind of supporting ring is combined into one with seal ring, good positioning effect, easy for installation, dismounting easily, the subdivision place connects facility and reliable sealing pair split type combination oil seals.
Solve the problems of the technologies described above and adopt following technological scheme: a kind of pair of split type combination oil seal, comprise supporting ring and seal ring, described supporting ring and seal ring are split type split composite structure.
Described supporting ring is a split type structure, and the two ends, subdivision place of this supporting ring are respectively equipped with bolt hole and with Bolt Connection, and the supporting ring inboard is provided with the groove that is used to connect with the fixing seal ring; The supporting ring outside is provided with the groove that is used to install O type circle; The outside, supporting ring back is provided with positioning step; Described seal ring comprises lip, bizet, spring groove, shoulder, boss, secondary lip and waist and is the split type integrative-structure; The lip of sealing ring is positioned on the bizet, and this bizet has spring groove, and spring is installed in the spring groove; Secondary lip is positioned at the waist outside; Boss is positioned at the shoulder outside, and waist links to each other with shoulder, and the two ends, subdivision place of sealing ring are respectively equipped with the guiding latch and connect matching mechanism with the guiding jack for guiding; Described supporting ring is radially encircled with boss that is positioned at the ring shoulder outside and shoulder through its inboard groove and is one.
According to technique scheme, the present invention can make the mould batch process, walks the standardization route, and is with low cost, easy to use, is widely used.In use; Only need guiding latch with seal ring subdivision place one end to insert the guiding jack of the other end and with the subdivision place bonding after; Hang up spring; The boss that again supporting ring is positioned at the seal ring shoulder outside through its inboard groove fit and shoulder are radially encircled the attachment bolt that seal ring and locking are positioned at two ends, supporting ring subdivision place, and to putting into the groove in the supporting ring outside after sticking, it is interior and positioning step and Seal cage end face evenly are adjacent to get final product to push Seal cage then in the lump with O type circle.The positioning step structure in the outside, supporting ring of the present invention back has not only solved the orientation problem of two split type combination oil seals well, and has been easy for installation and removal; Supporting ring and seal ring are split-type structural; And be provided with the guiding latch at seal ring subdivision place and connect matching mechanism with the guiding jack; Great facility is provided for the positions such as lip, bizet, waist, secondary lip and shoulder that connect with adhesive seal ring subdivision place, the connection at seal ring subdivision place and bonding being easy to are turned one's hand over.
Compared with prior art, the invention has the beneficial effects as follows:
⑴ only need remove original-pack oil sealing when installing, need not remove or mobile device on other any parts, install extremely convenient and swift;
⑵ because supporting ring and seal ring are split-type structural, for connecting and the subdivision place of adhesive seal ring provides great facility;
⑶ adopt the guiding latch to connect matching mechanism with the guiding jack seal ring subdivision place is connected, and is aided with gluingly simultaneously, can realize sealability identical with unitized seal and effect;
⑷ the positioning step design on the supporting ring makes two split type combination oil seal location clock like precision and convenient.If supporting ring in the supporting ring and positioning ring are processed into the split type Structural Hardware, therebetween with Bolt Connection, then can use for a long time, when changing oil sealing next time, only need change seal ring, thereby save great amount of cost;
⑸ the present invention is applicable to the sealing that reaches to various lubricant mediums and lubricating system, and reaches the sealing effect of unitized seal.And process easy, with low cost.
