Abstract
The utility model discloses a piston rod. The piston rod comprises a truck loading end, a rod body and a work end, wherein the piston rod is made of polyphenylene sulfide; one end of the rod body is connected with the truck loading end and the other end of the rod body is connected with the work end; a limit groove is formed in the truck loading end; a limit groove is formed in the work end; a concave ring is arranged in the middle of the rod body; and a graphite ring is mounted on the concave ring. The piston rod is lower in cost, light in weight and self-lubricating.
Description
Technical field
The utility model relates to axle class technical field, specifically relates to a kind of piston rod.
Background technique
Existing piston rod mostly is greatly metal material, and the power that this piston rod transmits is large, long service life.But in many occasions, the occasion of high speed light loading particularly, the shortcoming that metallic piston inertia is large has just come out, and for the lower occasion of ask for something, the cost of metallic piston bar is too high again, and the liquid lubrication of existing most of piston rod has also strengthened its user cost greatly.
The model utility content
The technical problem that (one) will solve
For the deficiency that prior art exists, the utility model provides a kind of cost lower, and quality is light, the piston rod of energy selflubricating.
(2) technological scheme
For achieving the above object, the utility model provides a kind of piston rod, comprises entrucking end, shaft and working end; The material of described piston rod is polyphenylene sulfide, one termination entrucking end of described shaft, another termination working end of described shaft, have a restraining groove on the described entrucking end, also have a restraining groove on the described working end, there is a scrobicular ring at described shaft middle part, fill graphite annulus on the described scrobicular ring, described graphite annulus is comprised of two semi-rings, and two semi-rings blocked respectively the described scrobicular ring of people when described graphite annulus was installed, and is bonding by glue between described graphite semi-ring and the shaft.
(3) beneficial effect
The utility model piston rod cost is low, quality light, self-lubricating function is arranged.
Description of drawings
Fig. 1 is the structural representation of piston rod of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The structure of piston rod of the present utility model comprises entrucking end 1, shaft 2 and working end 3 as shown in Figure 1; The material of described piston rod is polyphenylene sulfide, one termination entrucking end 1 of described shaft 2, another termination working end 3 of described shaft 2, have a restraining groove 4 on the described entrucking end 1, also have a restraining groove 6 on the described working end 3, there is a scrobicular ring at described shaft 2 middle parts, dress graphite annulus 5 on the described scrobicular ring, described graphite annulus 5 is comprised of two semi-rings, and two semi-rings blocked respectively the described scrobicular ring of people when described graphite annulus 5 was installed, and are bonding by glue between described graphite semi-ring and the shaft.
The beneficial effects of the utility model: the piston rod cost is low, quality light, self-lubricating function is arranged.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
