Abstract
The invention discloses a greased rust-proof coupler. The greased rust-proof coupler comprises a left half coupler and a right half coupler; the outer wall of the right half coupler, which is close to the left end portion of the right half coupler, is fixedly connected with a connecting cylinder matched with the left half coupler, and the inner wall of the connecting cylinder is provided with internal threads; the outer wall of the left half coupler, which is close to the right end of the left half coupler, is provided with external threads matched with the internal threads. According to the greased rust-proof coupler, the inner wall of the connecting cylinder is provided with the internal threads, and the outer wall of the left half coupler, which is close to the right end of the left half coupler, is provided with the external threads matched with the internal threads, so that people can assemble and disassemble the greased rust-proof coupler; the middle of the outer wall of the connecting cylinder is radially provided with a plurality of greasing holes, which can facilitate greasing and disassembly when the coupler is not used for a long time; a dust-proof layer can protect the connecting cylinder from external corrosion.
Description
Technical field
The present invention relates to a kind of coupling, relate in particular to the antirust coupling of a kind of oiling.
Background technique
Coupling is that two axles (driving shaft and driven shaft) for connecting in different institutions make it the mechanical parts of common rotation with transmitting torque.In the power transmission of high-speed overload, it is the effect of dynamic performance that some coupling also has buffering, vibration damping and raising axle.But the coupling using at present, exists the shortcoming of complex structure, dismounting inconvenience, and does not use for a long time, easily produces rust staining, not quick detachable.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides the antirust coupling of a kind of oiling.
To achieve these goals, the technical solution used in the present invention is: the antirust coupling of a kind of oiling, comprise left half-coupling and right half-coupling, the outer wall of right half-coupling is fixedly connected with a connecting cylinder mating with left half-coupling near left part place, the inwall of connecting cylinder is provided with internal thread, the outer wall of left half-coupling is provided with the outside thread mating with internal thread near right part place, the outer wall of connecting cylinder middle part radially has several oil holes along connecting cylinder, and the outer wall of connecting cylinder is coated with resin layer.
As preferably, oil hole is four and is uniformly distributed.
Compared with prior art; the invention has the advantages that: the inwall of connecting cylinder is provided with internal thread; the outer wall of left half-coupling is provided with the outside thread mating with internal thread near right part place; be convenient for people to dismounting; the outer wall middle part of connecting cylinder radially has several oil holes along connecting cylinder, in the time not using for a long time, can facilitate oiling; convenient dismounting, resin layer protection connecting cylinder is not corroded by the external world.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1, left half-coupling; 2, right half-coupling; 3, connecting cylinder; 4, oil hole; 5, resin layer.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As one embodiment of the present invention, consult Fig. 1, the present invention includes left half-coupling 1 and right half-coupling 2, the outer wall of right half-coupling 2 is fixedly connected with a connecting cylinder 3 mating with left half-coupling 1 near left part place, the inwall of connecting cylinder 3 is provided with internal thread, the outer wall of left half-coupling 1 is provided with the outside thread mating with internal thread near right part place, the outer wall middle part of connecting cylinder 3 is along the several oil holes 4 of radially having of connecting cylinder 3, and the outer wall of connecting cylinder 3 is coated with resin layer 5.Oil hole 4 is four and is uniformly distributed.
The inwall of connecting cylinder 3 of the present invention is provided with internal thread; the outer wall of left half-coupling 1 is provided with the outside thread mating with internal thread near right part place; be convenient for people to dismounting; the outer wall middle part of connecting cylinder 3 is along the several oil holes 4 of radially having of connecting cylinder 3; in the time not using for a long time; can facilitate oiling, convenient dismounting, resin layer 5 protects connecting cylinder 3 not corroded by the external world.
Although be recognized as a most practical and preferred embodiment and described the present invention in conjunction with current, but be to be understood that, the invention is not restricted to the disclosed embodiments, and be intended on the contrary contain multiple amendment and equivalent arrangements included in the spirit and scope of the appended claims.
Claims (2)
1. the antirust coupling of oiling, comprise left half-coupling and right half-coupling, it is characterized in that: the outer wall of described right half-coupling is fixedly connected with a connecting cylinder mating with left half-coupling near left part place, the inwall of described connecting cylinder is provided with internal thread, the outer wall of described left half-coupling is provided with the outside thread mating with internal thread near right part place, the outer wall middle part of described connecting cylinder radially has several oil holes along connecting cylinder, and the outer wall of described connecting cylinder is coated with resin layer.
