Description
Technical field
The present invention relates to a kind of shaft coupling, specifically a kind of permanent protective property 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, by flanged joint between two internal tooth casings of two half a couplers, tradition is this
There are many defects for the shaft coupling of structure, on the one hand, its complex structural designs, parts are more, and manufacture is of high cost；An other side
Face, dismounting trouble, maintenance are inconvenient；In another aspect, poor sealing, it is easy to make oil leak, reduce use reliability.
Invention content
The technical problem to be solved in the present invention is to provide a kind of structure design is simple, convenient for disassembly and assembly, good airproof performance, using can
The permanent protective property shaft coupling leaned on.
In order to solve the above-mentioned technical problem, permanent protective property shaft coupling of the invention, including being connected in two sections of shafts
Former and later two half a couplers, the end of preceding half a coupler is provided with the internal tooth casing that diameter is more than shaft diameter, rear half a coupler
End be provided with limited step, the forepart of limited step is provided with keyway and is equipped on the half a coupler by key outer
Tooth set, external tooth cover are extend into the inner cavity of internal tooth casing, further include one have annular compression ring end cover, end cover it is interior
Side portion compresses are on the end face of limited step, and the exterior portion of end cover is pressed on the end face of internal tooth casing, annular compression ring
Between internal tooth casing and external tooth cover and it is pressed on the end face of external tooth cover.
The end of inner ring shape sealing ring, the end cover and internal tooth casing is provided between the end cover and limited step
Outer shroud shape sealing ring is provided between face.
The thickness of inboard portion is less than the thickness of its exterior portion in the end cover.
It is provided between the external peripheral surface of the inner circumferential surface of the end cover and rear half a coupler positioned at limiting stand
End part seal circle on rear side of rank.
After above-mentioned structure, due to be provided on the half a coupler at rear portion limited step and with annular compression ring
Limited step cooperation end cover, annular compression ring is between internal tooth casing and external tooth cover and is pressed on the end face of external tooth cover,
A reliable labyrinth seal structure is consequently formed, improves sealing reliability, avoids other oil leak problem,
Structure design advantages of simple, parts are few, and dismounting is very convenient quick, facilitates and overhauls and reduce manufacture cost.
Description of the drawings
Fig. 1 is the cross-sectional view of permanent protective property shaft coupling of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, the permanent protective property shaft coupling of the present invention is described in further detail.
As shown in the figure, the permanent protective property shaft coupling of the present invention, including be connected in two sections of shafts former and later two half
Shaft coupling, the end of preceding half a coupler 1 are provided with the internal tooth casing 2 that diameter is more than shaft diameter, the end setting of rear half a coupler 3
There is limited step 4, the forepart of limited step 4 is provided with keyway and is equipped with external tooth cover 6 by key 5 on the half a coupler,
External tooth cover 6 is extend into the inner cavity of internal tooth casing 2, and front end is limited by the end face of forepart half a coupler, and its rear end passes through limiting
Step limits, and further includes an end cover 8 with annular compression ring 7, the inboard portion of end cover 8 is pressed on limited step
On 4 end face, the exterior portion of end cover 8 is pressed on the end face of internal tooth casing 2, and annular compression ring 7 is located at internal tooth casing and external tooth
Between set and it is pressed on the end face of external tooth cover 6.
Further, leakproofness in order to better improve is provided with inner ring between end cover 8 and limited step 4
Outer shroud shape sealing ring 10, the inner periphery of end cover 8 are provided between the end face of shape sealing ring 9, end cover 8 and internal tooth casing 2
The end part seal circle 11 being provided between the external peripheral surface of surface and rear half a coupler 3 on rear side of limited step, in addition, close
The thickness for blocking inboard portion in lid 8 is less than the thickness of its exterior portion.
