Description
Technical field
The present invention relates to a kind of shaft coupling, specifically a kind of thread seal shaft coupling.
Background technology
Traditional drum-shaped tooth type shaft coupling generally comprises two half a couplers, and there are one outer respectively for each half a coupler
Tooth shaft and the internal tooth casing being sleeved on outside outer tooth shaft pass through flanged joint between two internal tooth casings of two half a couplers, it is well known that
Shaft coupling is typically all by end cap and sealing ring sealing installation, existing this structure during the connection process, on the one hand, by
It is installed in using sealing ring, sealing part is relatively more, permanent using easily sealing ring being made to fail, and makes oil leak, reduces
The reliability used, in addition, it is also necessary to often replace sealing ring, waste manpower and materials, affect normal use, in addition a side
Face, the end cap of use are directly positioned on shaft end, permanent to use, and easily end cap is damaged, affects service life.
Invention content
The technical problem to be solved in the present invention is to provide a kind of sealing part is few, use reliability is good, long-lived spiral shell
Line sealed coupler.
In order to solve the above-mentioned technical problem, thread seal shaft coupling of the invention, including being connected in two sections of shafts
The half a coupler of left and right two and for be mounted on left and right two half a couplers between internal tooth casing, one end of internal tooth casing opens
Open, other end have with the right comparable placement hole of half a coupler outer diameter, form two-stage stepped hole in the inner cavity of internal tooth casing, right half
The end of shaft coupling is provided with limited step, and the forepart of limited step is provided with keyway and is pacified on the half a coupler by key
Equipped with external tooth cover, right half a coupler passes through the placement hole of internal tooth casing and limited step is made to limit at first order stepped hole, external tooth
Set is located at into the inner cavity of internal tooth casing and the right end face of internal tooth casing is made to limit at the stepped hole of the second level, the end of left half a coupler
End is provided with the annular installation end that diameter is more than shaft diameter, and internal and external threads, internal tooth are provided with inside and outside annular installation end
The openend of set is provided with the threaded hole of annular, and left half a coupler is mounted on the openend of internal tooth casing by annular installation end.
The internal tooth casing open end side forms annular inner portion and outer ring portion by threaded hole, and the height of the annular inner portion is low
In the height of outer ring portion, the annular installation end 7 has the annular groove coordinated with annular inner portion, and the annular installation end passes through ring
Slot is mounted on the annular inner portion of internal tooth casing.
No.1 sealing ring is mounted in the annular groove, the annular installation end is sealed in annular installation by No.1 sealing ring
Between end and the annular inner portion of internal tooth casing.
It is provided with and is located between the external peripheral surface of the inner circumferential surface of placement hole and right half a coupler in the internal tooth casing
No. two sealing rings on rear side of limited step.
After above-mentioned structure, half shaft coupling of the right side due to the internal tooth casing with stepped hole of setting, with limited step
Device and the left half a coupler with annular installation end, external tooth can be packed into capable limiting from there through stepped hole, when mounted,
Installed by annular installation end and internal tooth casing and external tooth cover be encapsulated in internal tooth casing, not only eliminate traditional end cap with
And sealing ring, it will not be because of the reliability that sealing ring failure effect uses, sealing part is few, improves sealing performance, and will connect
Seam end is staggered with inner cavity and further ensures sealing performance, and the screw connection structure at the same time set further ensures sealing
Performance not only ensure that its permanent use, solve the problems such as manpower and materials traditionally replaced needed for sealing ring, and it is tied
Structure design is simple, convenient to disassembly, facilitates and overhauls and reduce manufacture cost, extends service life.
