Abstract
The utility model relates to a novel axial coupling. The axial coupling comprises two couple axes, a button and a sleeve coupling, and is characterized in that the two coupled axes are connected to the sleeve coupling with the button; a groove is provided outside the button of the two coupled axes, in which retaining rings are provided; the retaining rings are pressed by pressing boards, which are connected to sleeve coupling with bolts. Inner broken corners are provided on the pressing boards and the sleeve coupling to fit the retaining rings. The advantage of the utility model is that the minimum diameter of the rear coupling axis is 89 percent of that of the original axis, which greatly enhance the axis intensity; moreover, processing of the coupling is simpler, which reduces the production cost.
Description
Technical field
The utility model relates to a kind of axle coupling parts that are used for vertical sewage pump, particularly a kind of novel axle coupling.
Background technique
Vertical sewage pump belongs to the major axis pump, and its axial length is generally at several meters to tens meters, and so long axle can not be made an integral body, must make plurality of sections and link together with coupling then.Owing to will adorn shaft coupling in the existing coupling parts, therefore need process axle head, but the minimum diameter of processing rear axle has only 60% of original diameter, this has just weakened the intensity of axle greatly, and just must increase the diameter of primitive axis, thereby cause very big waste as the intensity that will increase axle.Simultaneously original coupler structure complexity, the processing cost is higher.
Summary of the invention
The purpose of this utility model is to solve the prior art axis need process and process the back primitive axis connecting end problem that the intensity of existing axle reduces that attenuates with coupling to primitive axis when the shaft coupling, provides a kind of novel to use coupling.The utility model designs a kind of novel axle coupling, comprise two velamen shaft couplings, key, cover bucket coupling, it is characterized in that: key connecting sleeve bucket coupling is arranged on two velamen shaft couplings, the outside of key is fluted on two velamen shaft couplings, snap ring is arranged in groove, snap ring is pressed mutually by pressing plate, and pressing plate is connected on the cover bucket coupling by screw.On pressing plate and the cover bucket coupling the interior unfilled corner that cooperates with snap ring is arranged all.The utility model advantage is that the minimum diameter of shaft coupling rear axle is 89% of original axle, has improved the intensity of axle greatly, and in shaft coupling processing also than simply many originally, reduced cost of production.
Description of drawings
Accompanying drawing 1 is the prior art structural representation.
Accompanying drawing 2 is the utility model structural representations.
Embodiment
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Comprise two velamen shaft couplings 1, key 2, cover bucket coupling 3 among the figure, it is characterized in that: key 2 connecting sleeve bucket coupling 3 are arranged on two velamen shaft couplings 1, the outside fluted 4 of key 2 on two velamen shaft couplings 1, snap ring 5 is arranged in groove 4, snap ring 5 is pressed mutually by pressing plate 6, and pressing plate 6 connects two velamen shaft couplings 1 by screw 7 and is connected on the cover bucket coupling 8.On pressing plate 6 and the cover bucket coupling 3 the interior unfilled corner 8 that cooperates with snap ring 5 is arranged all.Process keyway in the end of two velamen shaft couplings 1 during connection, by key 2 two velamen shaft couplings 1 and cover bucket coupling 3 are coupled together, on two velamen shaft couplings 1, process groove 4 snap ring 5 is installed, be pressed in above the snap ring 5 with pressing plate 6 then, pressing plate 6 and a cover bucket coupling 3 linked together and tighten with screw 7, like this about two velamen shaft couplings 1 just be joined together.Compare very shallowly with the diameter of primitive axis because of the groove 4 that snap ring 5 is installed, therefore can improve the intensity of integral shaft behind the shaft coupling greatly.
