Description
Technical field
The utility model relates in a kind of machinery running shaft with bearing housing or gear box lubricating oil (fat) seal arrangement, specifically a kind of two split type opening oil sealings of bit-type of making by oneself.
Background technique
At present, oil sealing on the market (as GB GB/T9877.1～9877.3-1998 defined), its profile is integral ring-shaped closing structure, this structural entity good seal performance, but when installing, other parts that must remove in the Seal cage outward turning rotating shaft could be pushed into the oil sealing mounting point of presetting in the Seal cage along an end of axle with oil sealing, like this, not only time-consuming taking a lot of work, and other parts that can damage equipment when changing oil sealing.Particularly in case of emergency, as when repairing, can because of remove and install operation more loaded down with trivial details or in replacing oil sealing process damage equipment influence production.
In the actual mechanical process of device maintenance, the way with the bonding use of whole J type oil sealing otch is arranged also in case of emergency.But cause the otch dislocation can not reach desirable sealing effect because of can't correctly docking eventually.
Split type oil sealing of Tui Chuing or opening oil sealing 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; Perhaps material effect is better but installed difficulty or is caused costing an arm and a leg and can't be used widely 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 class opening oil sealing still exists opening connection (gluing) to connect deficiencys such as difficulty, applying weak effect, has a strong impact on sealing effect.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, provide that a kind of supporting positioning ring is combined into one with lip seal, good positioning effect, easy for installation, dismounting easily, the subdivision place connects facility and reliable sealing is made bit-type pair split type opening oil sealings by oneself.
Solve the problems of the technologies described above by the following technical solutions: a kind of two split type opening oil sealings of bit-type of making by oneself, comprise supporting positioning ring and lip seal, described supporting positioning ring and lip seal are that split type divides body structure, and this supporting positioning ring and lip seal are radially encircled and be combined into one.
According to technique scheme, compared with prior art, the utility model can be made the mould batch process, walks the standardization route, and is with low cost, easy to use, is widely used.In use, only need after the connection of lip seal subdivision place, hang up spring, to support the trapezoidal connection slot of positioning ring by its inboard again and cooperate the trapezoidal connection tenon and the shoulder that are positioned at the lip seal shoulder outside radially to encircle lip seal, and push seal chamber and make positioning ring and the Seal cage end face evenly is adjacent to and gets final product along running shaft in the lump then.The integral structure of supporting ring of the present utility model and positioning ring has not only solved the orientation problem of making the two split type opening oil sealings of bit-type by oneself well, and has been easy for installation and removal; Supporting positioning ring and lip seal are split-type structural, provide a great convenience for connection and bonding lip seal B-D subdivision place, and can guarantee the precisely bonding of each position, B-D subdivision place, guarantee that its sealability approaches self-contained oil sealing.
Compared with prior art, the beneficial effects of the utility model are:
Only need remove original-pack oil sealing when (1) installing, need not remove or mobile device on other any parts, install extremely convenient and swift.
(2) because supporting positioning ring and lip seal are split-type structural, the place of dissecing with bonding lip seal provides a great convenience for connection.
(3) under complete visual condition, can realize the precisely bonding of lip seal subdivision place, thereby realize the sealing effect close with self-contained oil sealing.
(4) the positioning ring design on the supporting positioning ring makes and makes the two split type opening oil sealing location clock like precision of bit-type and convenient by oneself.If the supporting ring and the positioning ring that will support in the 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 lip seal, thereby save great amount of cost.
(5) this edible novel splash oil lubrication or dry oil lubrication environment of being applicable to.
