Abstract
The utility model discloses a coupling for a pumping unit. The coupling comprises two coupling haves respectively connected onto two sections of rotating shafts, wherein the tail end of one coupling half is provided with a connecting sleeve with inner teeth, and the outer circumference of the tail end of the other coupling half is provided with outer teeth matched with the inner teeth of the connecting sleeve; the outer teeth are sealed in the sealing sleeve by a sealing sleeve positioned at the back of the outer teeth after the connecting sleeve is sleeved on the outer teeth. With the structure, the coupling half with the outer teeth is sleeved in the other coupling half during connecting, the structure is very simple, the parts are few, the manufacturing cost is low, and the assembly, disassembly and maintenance are very inconvenient; meanwhile, the sealing links are few, the sealing performance is improved, so the lubricating oil can not be leaked, in addition, the traditionally used flanges are removed in the connecting process, the two sections of rotating shafts can relatively slide, and the coupling can bear certain axial and radial offset when being used on the pumping unit and other equipment.
Description
Technical field
The utility model relates to a kind of coupling, specifically a kind of used for oil extractor coupling.
Background technique
Traditional crown gear coupling, generally comprise two half-couplings, each half-coupling has respectively an external tooth axle and is enclosed within the internal tooth casing outside external tooth axle, between two internal tooth casings of two half-couplings, by flange, connect, the coupling of this structure of tradition, on the one hand, complex structure, component are more, and manufacture cost is high; In addition on the one hand, dismounting trouble, maintenance inconvenience; On the one hand, sealing part is many again, therefore causes sealing poor, is easy to make oil leak, more on the one hand, two half-couplings connect by flange, and rigidity is strong, in the time of on being used in the equipment such as pumping unit, can not bear certain side-play amount.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, and cost is low and can bear the used for oil extractor coupling of certain deviation amount.
In order to solve the problems of the technologies described above, used for oil extractor coupling of the present utility model, comprise two half-couplings that are connected in two sections of rotating shafts, the end of one of them half-coupling is set to have the connecting sleeve of internal tooth, on the excircle of another one half-coupling end, be provided with the external tooth matching with the internal tooth of connecting sleeve, after connecting sleeve is enclosed within on external tooth, by a stuffing box gland that is positioned at external tooth rear, external tooth be sealed in to connecting sleeve.
Between the external diameter of described stuffing box gland and the internal diameter of connecting sleeve, be provided with O-ring seals.
On described connecting sleeve, have and can to the cavity between connecting sleeve and external tooth, inject the lubricant oil hand-hole of lubricant oil, on lubricant oil hand-hole, priming cup is installed.
Adopt after above-mentioned structure, because one of them half-coupling has connecting sleeve, another one half-coupling is provided with the external tooth matching with the internal tooth of connecting sleeve, during connection, the half-coupling with external tooth is enclosed within another one half-coupling, its structure is very simple, component are few, low cost of manufacture, and dismounting maintenance is very inconvenient; Meanwhile, sealing part is few, has improved sealing, can not make oil leak, in addition, has removed the flange using in tradition in connection procedure, and two sections of rotating shafts can relative sliding, in the time of on being used in the equipment such as pumping unit, can bear certain axially and radial deflection amount.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model used for oil extractor coupling.
Embodiment
Below in conjunction with the drawings and specific embodiments, used for oil extractor coupling of the present utility model is described in further detail.
As shown in the figure, used for oil extractor coupling of the present utility model, comprise two half-couplings that are connected in two sections of rotating shafts, the end of one of them half-coupling is set to have the connecting sleeve 4 of internal tooth, on the excircle of another one half-coupling end, be provided with the external tooth matching with the internal tooth of connecting sleeve, said external tooth is crowned teeth, the formed axle of this half-coupling with external tooth is referred to as external tooth axle, after being enclosed within on external tooth, connecting sleeve 4, by a stuffing box gland 2 that is positioned at external tooth rear, external tooth is sealed in to connecting sleeve 4, between the external diameter of the internal diameter of stuffing box gland 2 and external tooth axle, it is interference fit, between the internal diameter of the external diameter of stuffing box gland 2 and connecting sleeve 4, be provided with O-ring seals 3, can directly utilize seal ring to seal thus, sealing configuration is very simple, sealing effect is but very good.
Further, on said connecting sleeve 4, have and can inject to the cavity between connecting sleeve and external tooth the lubricant oil hand-hole 1 of lubricant oil, priming cup 5 is installed on lubricant oil hand-hole 1, can facilitates thus lubricant oil to inject, also available lubricating grease is lubricated simultaneously.
