Description
Technical field
The utility model relates to a kind of double oil roller chain.
Background technology
The petroleum-type conventional machinery equipment such as chain drive pumping unit its to have structure simple and easily realize long stroke, heavy loading; the advantage of light weight and efficient energy-saving; obtain using more widely in each oil field; and oil roller chain compares common component in the equipment such as chain drive pumping unit; existing oil roller chain is for oil equipment, stability and poor reliability, and failure rate is higher; often there will be various fault, add the work-ing life of maintenance cost and equipment.
Practical novel content
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, the double oil roller chain of firm and durable, stability and good reliability, failure rate is low and long service life.
For solving the problem, the utility model adopts following technical scheme:
A kind of double oil roller chain, comprise the middle carrier bar that two rows are oppositely arranged, and it is arranged on the inner plate of middle carrier bar both sides, and it is arranged on the roller of inner plate both sides, and it is arranged on the sleeve inside roller, and it is arranged on the special-shaped pin link plate of roller side, and it is arranged on the common pin link plate of another side of roller, and run through middle carrier bar, inner plate, roller, sleeve, the bearing pin of abnormity pin link plate and common pin link plate, and it is arranged on outside abnormity pin link plate, and for connecting the only lock pin of two ends bearing pin, described common pin link plate and bearing pin are that shrink-fit connects, on described abnormity pin link plate, two ends are provided with perforation, described perforation is D type structure, and shrink-fit mutual to bearing pin is connected.
As preferably, described middle carrier bar both sides are respectively provided with two inner plates, described roller, between two inner plates of middle carrier bar side, increases its firm property and reliability.
As preferably, described only lock pin middle-end is U-shape structure, not easily deviates from, more firmly.
As preferably, described only lock pin is steel wire only lock pin, and employing steel wire is material, increases its stability.
The beneficial effects of the utility model are: be provided with common pin link plate and abnormity pin link plate on a kind of double oil roller chain of the utility model, common pin link plate and abnormity all mutual with the bearing pin shrink-fit of pin link plate are connected, and outside the common pin link plate in one end its two ends bearing pin between be connected with only lock pin, simultaneously, perforation on abnormity pin link plate adopts D-shape configuration, being possible to prevent bearing pin to rotate, overall chain structure firm and durable, stable and reliability height, effectively improve the work-ing life of chain.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, it is briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of double oil roller chain of the utility model;
Fig. 2 is the front view of single-unit in a kind of double oil roller chain of the utility model;
Fig. 3 is the rear view of single-unit in a kind of double oil roller chain of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made more explicit defining.
Consult shown in Fig. 1 to Fig. 3, a kind of double oil roller chain, comprise the middle carrier bar 3 that two rows are oppositely arranged, and it is arranged on the inner plate 2 of middle carrier bar 3 both sides, and it is arranged on the roller 6 of inner plate 2 both sides, and it is arranged on the sleeve 5 inside roller 6, and it is arranged on the special-shaped pin link plate 8 of roller 6 side, and it is arranged on the common pin link plate 1 of another side of roller 6, and run through middle carrier bar 3, inner plate 2, roller 6, sleeve 5, the bearing pin 4 of abnormity pin link plate 8 and common pin link plate 1, and it is arranged on outside abnormity pin link plate 8, and for connecting the only lock pin 7 of two ends bearing pin 4, described common pin link plate 1 and bearing pin 4 are shrink-fit connection, on described abnormity pin link plate 8, two ends are provided with perforation 9, described perforation 9 is D type structure, and shrink-fit mutual to bearing pin 4 is connected.
Described middle carrier bar 3 both sides are respectively provided with two inner plates 2, and described roller 6, between two inner plates 2 of middle carrier bar 3 side, increases its firm property and reliability.
Described only lock pin 7 middle-end is U-shape structure, not easily deviates from, more firmly.
Described only lock pin 7 is steel wire only lock pin, and employing steel wire is material, increases its stability.
In the present embodiment, common pin link plate 1 adopts shrink-fit with bearing pin 4, and adopt steel wire to be that the only lock pin 7 of material connects, guaranteeing that common pin link plate 1 is fixed, abnormity pin link plate 8, its perforation 9 is designed to D shape, and pin 4 adopts shrink-fit with connecing, and rivet, being possible to prevent bearing pin 4 in axial rotation, one-piece construction can improve the work-ing life of chain greatly, promotes about 30%.
The beneficial effects of the utility model are: be provided with common pin link plate and abnormity pin link plate on a kind of double oil roller chain of the utility model, common pin link plate and abnormity all mutual with the bearing pin shrink-fit of pin link plate are connected, and outside the common pin link plate in one end its two ends bearing pin between be connected with only lock pin, simultaneously, perforation on abnormity pin link plate adopts D-shape configuration, being possible to prevent bearing pin to rotate, overall chain structure firm and durable, stable and reliability height, effectively improve the work-ing life of chain.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
