Abstract
The utility model discloses the long key force transmission mechanism of a kind of straight-through type, comprise pump shaft and some groups of impeller assemblies, described pump shaft outer side wall is provided with straight-through type keyway, impeller assembly described in some groups is fixed in described straight-through type keyway successively by long key, and is fixed by the first axle shelves at described pump shaft two ends and the second axle shelves; Described impeller assembly comprises impeller, the second axle sleeve, lifting force dish and the middle axle sleeve of arranging successively.All keyways are merged into straight-through type keyway by the utility model, only need disposable processing, and technique is simple, guarantees machining accuracy; Coordinated with all parts by long key simultaneously, be installed on long key in order by other parts, overall assembling is simple, and structure is reliable, ensures the integrity of part.
Description
Technical field
The utility model relates to a kind of static connection driving mechanism, is specifically related to the long key force transmission mechanism of a kind of straight-through type.
Background technique
Current axle with parts on shaft in order to transmitting torque generally adopts short flat key to be connected, when the number of spare parts that axle connects is more, need to spline technique to each mounting parts position on axis body, be discrete segmented keyway between each keyway, be difficult to the straightness accuracy of guarantee keyway.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides a kind of straight-through type long key force transmission mechanism, ensures machining accuracy.
Technological scheme: the long key force transmission mechanism of straight-through type described in the utility model, comprise pump shaft and some groups of impeller assemblies, described pump shaft outer side wall is provided with straight-through type keyway, impeller assembly described in some groups is fixed in described straight-through type keyway successively by long key, and is undertaken spacing by the first axle shelves at described pump shaft two ends and the second axle shelves; Described impeller assembly comprises impeller, the second axle sleeve, lifting force dish and the middle axle sleeve of arranging successively.
Preferably, described first axle shelves are integrated shaft shelves, and described second axle shelves are split type axle shelves.
Preferably, outside described first axle shelves, be provided with fixing end cap, inside described first axle shelves, be provided with the first axle sleeve.
Preferably, described impeller assembly is two groups, is provided with the second axle sleeve described in two groups between impeller assembly.
Beneficial effect: all keyways are merged into straight-through type keyway by (1), only needs disposable processing, and technique is simple, guarantees machining accuracy; (2) coordinated with all parts by long key, be installed on long key in order by other parts, overall assembling is simple, and structure is reliable, ensures the integrity of part.
Accompanying drawing explanation
Fig. 1 is static connection driving mechanism structural representation described in the utility model.
