Abstract
The utility model discloses a locating structure of a straight shaft bearing; the locating structure comprises locating sleeves arranged on a straight shaft; the locating sleeves are arranged at both sides of the bearing; a stepped barrel is arranged at the front end of each locating sleeve, wherein the external diameter of the stepped barrel is smaller than that of the locating sleeve; the stepped barrel is in interference fit with the straight shaft; the stepped barrel of one of the locating sleeves reaches against one side of the bearing; and the bottom end surface of the other locating sleeve reaches against the other side of the bearing. When the locating sleeves are arranged, the locating structure pushes the locating sleeves to a locating place of the bearing on the straight shaft, and then the stepped barrels are compacted so as to realize location, thereby being very convenient; during location, the two locating sleeves are matched for use; one side of the bearing is located by the stepped barrels, and the other side of the bearing is located by the locating sleeves; the bearing working is not affected while the bearing is accurately located.
Description
Technical field
The utility model relates to d-axis bearing assembly structure, particularly a kind of d-axis bearing position structure.
Background technique
Generally on small-sized, micromachine, adopt d-axis, and the bearing on the d-axis is because structure is less, be difficult for axially locating, and there is not the structure of positioning bearings such as the shaft shoulder on the d-axis, therefore the axially locating of bearing is relatively difficult, some adopts the structure or the mode of sleeve to realize, but relates to the axially locating of sleeve so again, and structure is complicated.
The model utility content
Problem to be solved in the utility model just provides a kind of d-axis bearing position structure, and is simple in structure, easy for installation, can be exactly with d-axis bearing axially locating.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of d-axis bearing position structure, comprise the setting sleeve that is located on the d-axis, it is characterized in that: the both sides at bearing are equipped with setting sleeve, the front end of setting sleeve is provided with the external diameter step cylindrical shell littler than the external diameter of setting sleeve, step cylindrical shell and d-axis interference fit, the step cylindrical shell of one of them setting sleeve is against a side of bearing, and the bottom end of another setting sleeve is against on the opposite side of bearing.
Further, the external diameter of described step cylindrical shell is not more than the external diameter of bearing inner race.
Further, the external diameter of described setting sleeve is not more than the internal diameter of bearing outer ring.
Further, described setting sleeve and d-axis transition fit.Be convenient to install.
Further, described setting sleeve and d-axis interference fit.Add strong fix.
After adopting technique scheme, the utlity model has following advantage: when installing and locating is overlapped, setting sleeve is pushed into d-axis upper bearing (metal) location and locates, compress the step cylindrical shell then and can realize the location, very convenient, be used with two setting sleeves when the location, bearing one side is by step cylindrical shell location, and the bearing opposite side is located by setting sleeve, accurately positioning bearing does not in like manner influence bearing working yet.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is the structural representation of setting sleeve.
Embodiment
A kind of embodiment's of the utility model structural representation as illustrated in fig. 1 and 2, a kind of d-axis bearing position structure, comprise the setting sleeve 2 that is located on the d-axis 1, both sides at bearing 4 are equipped with setting sleeve, the front end of setting sleeve is provided with the external diameter step cylindrical shell 3 littler than the external diameter of setting sleeve, step cylindrical shell and d-axis interference fit, the step cylindrical shell of one of them setting sleeve is against a side of bearing, and the bottom end of another setting sleeve is against on the opposite side of bearing.The external diameter of step cylindrical shell is not more than the external diameter of bearing inner race, and the external diameter of setting sleeve is not more than the internal diameter of bearing outer ring.Setting sleeve and d-axis transition fit.
In the foregoing description, setting sleeve also can be arranged to and the d-axis interference fit, can strengthen locating effect.
When installing and locating is overlapped, setting sleeve is pushed into place, d-axis upper bearing (metal) location, compresses the step cylindrical shell then and can realize the location, very convenient, when the location, be used with two setting sleeves, bearing one side is by step cylindrical shell location, and the bearing opposite side is located by setting sleeve.
Except that above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
