Description
Technical field
The present invention relates to bearing performance detection technique field, relate in particular to a kind of assembly angular contact ball bearing device for measuring axial clearance.
Background technology
Just there is end-play single-row angular contact ball bearing in itself, and the angular contact ball bearing end-play after the assembly has just more strengthened.Combine suitable play angular contact ball bearing and be usually used on the machine tool chief axis, improve main axis stiffness and running accuracy.So play need to strictly be adjusted when the pairing angular contact ball bearing dispatched from the factory.
That the assembly angular contact ball bearing has is back-to-back, face-to-face, three kinds of basic matching forms of series connection, and matched bearing is at the two bearings bulge quantity of assembly face end with for δ 1+ δ 2 is end-play, as shown in Figure 1.
The assembly angular contact ball bearing that precision machine tool is used requires very strict to end-play, but existing measurement mechanism complex structure and measuring accuracy are low.Therefore, need a kind of accurately easy device for measuring axial clearance of development.
Summary of the invention
In order to overcome the existing defective of prior art, the purpose of this invention is to provide a kind of assembly angular contact ball bearing device for measuring axial clearance, it is simple in structure, and is easy to operate, and measuring accuracy is high.
To achieve these goals, technical scheme of the present invention is as follows:
Assembly angular contact ball bearing device for measuring axial clearance, comprise load piece, centering sleeve, cone spacer, outer ring spacer, packing ring and surveying instrument, the centering sleeve is placed on the platform of surveying instrument, gasket sleeve is on the centering sleeve, measured bearing is enclosed within on the centering sleeve, and the following of the inner ring of measured bearing supported by packing ring, and the load piece is placed on the measured bearing, cone spacer connects the inner ring of two measured bearings, and outer ring spacer connects the outer ring of two measured bearings.
Above-mentioned outer ring spacer is the annular ring that is made of separable pair of semi-ring.
The invention has the beneficial effects as follows:
1, outer ring spacer is made the two partly ring-like, easy to operate of separate type, is applicable to the bearing machining factory of various scales;
2, can guarantee measuring accuracy, the flatness of each parts end face, parallel error all require to be 0.0005mm, can guarantee the accuracy of form and position, the not centering of load piece, and the upper and lower end face easily processes;
3, adopt the centering sleeve, can guarantee bearing and the centering of each annex;
4, simple in structure, cost is low.
