In order to realize the purpose, the utility model discloses the technical scheme who adopts is: an improved self-aligning roller bearing cage pocket center appearance post, includes: an upper section column, a middle section column and a lower section column; the upper section column and the lower section column are both of an upper cone frustum structure and a lower cone frustum structure; a cylindrical structure is arranged between the upper cone frustum and the lower cone frustum; the upper cone frustum and the lower cone frustum are both of a structure with a large upper part and a small lower part.
Furthermore, the upper cone frustum is used for measuring the central inclination angle of the pocket; both sides of the upper end of the upper conical table are provided with a fillet structure with the R of 0.5; avoid acute angle scratch and prevent collision damage.
Further, the cylindrical table structure is used for measuring the diameter of the pocket;
furthermore, the lower cone frustum is used for measuring the cone angle and the cone height of the pocket;
furthermore, the outer diameter of the cylindrical table and the lower conical table is completely matched with the shape of the cage pocket; the size of the truncated cone part of the pocket hole can be effectively controlled; the hidden danger that the quality problem of the clamped roller is caused because the size of the root part of the pocket is small easily because the cone angle of the lower cone table of the original design sample column is required to be 2 times of the inclination angle of the pocket and cannot be effectively controlled is avoided;
furthermore, the middle-lower part of the designed sample column is consistent with the shape of the pocket, if the sample column is designed to only have the upper cone frustum as a measuring part, the central diameter and the inclination angle of the pocket can be still detected, and the measurement is simpler and more convenient;
furthermore, the upper cone frustum structure with the large upper part and the small lower part is more beneficial to the operation of inserting and pulling out the pocket holes by the sample columns, and is particularly suitable for products with small pocket hole diameters, such as products with pocket hole diameters of only about 10 mm.
When the measuring sample columns are used, the measuring sample columns are used in pairs, two measuring sample columns are placed in two pocket holes with the longest chord length on the circumference of the self-aligning roller bearing solid retainer, and then the circumscribed circle chord length and the inscribed circle chord length of the two measuring sample columns are measured by a vernier caliper; and then calculating the inclination angle value and the cone angle value of the pocket. And then calculating to obtain the central circle diameter and the central inclination angle of the pocket, changing the position of the pocket, measuring at multiple points and further evaluating the variation of the central circle diameter of the pocket, and evaluating whether the taper height and the taper angle of the pocket conical frustum meet the product requirements by using a dyeing method or direct visual observation.
The utility model has the advantages that:
compared with the original center sample column, the method has the advantages of simple manufacture, simple operation and high detection speed, and can meet the requirement of all detection of the relevant sizes of the pockets; the sample column has good size universality and is suitable for products with large or small diameter of the pocket; the method is more suitable for the requirements of fast-paced and high-precision production and processing.
