Abstract
A protective structure of the shaft coupling device outer ring checking surface, which is comprised of a shaft coupling device. The shaft coupling has an outer circular periphery surface, at least a circle of groove is arranged on the outer ring periphery, and the bottom surface of any groove is concentric with the circular periphery of the shaft coupling device. Through a bottom surface and a periphery groove concentric with the shaft coupling device arranged on the outer circular periphery surface of the shaft coupling device, the utility model takes the groove bottom surface as the standard circular periphery surface for shape and position error checking, and the groove bottom surface is not easy to be impact and scratched, guaranteeing the accuracy of the checking result of the shape and position error.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to coupling, the protection structure of particularly a kind of coupling outer ring check face.
Background technique:
Coupling is applied in a large amount of pump products.For the Security in the installation and operation that guarantees pump, need carry out the check of form and position tolerance to coupling.The surface, outer ring of coupling is the check surface of centering.In the prior art, surface, coupling outer ring is not provided with the protection structure, and coupling makes the surface, outer ring exist to collide with, the cut equivalent damage in producing and installing easily, therefore can not accurately check form and position tolerance.
Summary of the invention:
The purpose of this utility model provides the protection structure of a kind of coupling outer ring check face, and the protection structure of described this coupling outer ring check face will solve the easy impaired technical problem of check table face of coupling outer ring in the prior art.
The protection structure of this coupling of the present utility model outer ring check face is made of coupling; described coupling has an outer peripheral surface; wherein; at least be provided with a circle groove in the described outer peripheral surface, the bottom surface of any one described groove all is circumferential surfacies concentric with described coupling.
Further, described coupling is made of one first shaft coupling portion and one second shaft coupling portion, be respectively arranged with taper hole in the first shaft coupling portion and the second shaft coupling portion, the end face butt joint of the first shaft coupling portion and the second shaft coupling portion, its taper hole is positioned on the same axis, be respectively arranged with step hole in the butt joint end face of the first shaft coupling portion and the second shaft coupling portion, be respectively arranged with round nut in the step hole, the first shaft coupling portion is connected by flange arrangement with the second shaft coupling portion, the first shaft coupling portion has one first outer peripheral surface, the second shaft coupling portion has one second outer peripheral surface, is provided with the described groove of a circle in first outer peripheral surface, is provided with the described groove of a circle in second outer peripheral surface.
Further, the degree of depth of described groove is less than or equal to 2mm.
Working principle of the present utility model is: the bottom surface of the groove in the coupling outer peripheral surface is the circumferential surface concentric with coupling, is difficult for being collided with, scratching, and therefore can be used as the basic circle side face of check form and position tolerance.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is by being provided with the bottom surface circumferential groove concentric with coupling in the coupling outer peripheral surface, with the basic circle side face of groove floor as the check form and position tolerance, groove floor is difficult for being collided with, scratching, and has guaranteed the correctness of form and position tolerance assay.
