Abstract
The invention belongs to the technical field of bearing cage detection and provides a spherical roller bearing solid cage pocket detection method. The spherical roller bearing solid cage pocket detection method is suitable for detection of a pocket having a slope. The method is characterized in that, to begin with, central diameter measuring columns (1), the height of which is H, are prepared, wherein each central diameter measuring column (1) has a cylindrical section, the diameter of which is same with that of the pocket; the two ends of the cylindrical section are respectively provided with a cone section, the diameter of which is reduced gradually from the cylindrical section to the two ends, and the inclination angle of the cone section is same with the inclination angle of the cage pocket; during measuring, the two central diameter measuring columns (1) are disposed in two pockets, the chord length of which in the circumference is the longest, of a spherical roller bearing solid cage respectively; then, a vernier caliper is utilized to measure circumcircle chord length D2 and incircle chord length D0 of the two central diameter measuring columns; and then, the inclination angle value alpha of the pocket is calculated. The method solves the problem of measurement of the central diameter and the inclination angle of the pocket.
Description
Technical field
The invention belongs to retainer detection technique field, be specifically related to the detection method in a kind of aligning roller bearing solid retainer pocket hole.
Background technology
Conventional method now for self-aligning roller bearing entity retainer measuring center footpath is to adopt special measurement post, measures end face center-diameter or the method directly measuring pocket hole vertex (vertices) center-diameter.
Measure end face center shot: be individually positioned in by special measurement post in two pocket holes on keeper maximum chord length direction, in product end surface institute in radial directions, measuring two measurement column largest outside diameter chord lengths, this measurement chord length conversed with product design center-diameter contrasts；Being the center-diameter (chord length) of pocket orifice part due to what measure, the quality of fit of pocket bore dia and measurement column directly affects certainty of measurement, and operation easier is big and error is relatively big, and certainty of measurement also has impact.
Measure vertex (vertices) center shot: measure retainer largest chord two pocket hole drill heart vertex (vertices) distance, contrast with scaled value；Owing to the distances being difficult to two unbearable points in the process measured accurately are measured, simultaneously for the processing of drill bit and unbearable be formed with high requirement, error is bigger.
Both the above center-diameter measuring method, one is the deficiency of certainty of measurement, and two is the angle of inclination that cannot measure pocket hole, and dip angle of hole can only lean on equipment adjustment to ensure.
Summary of the invention
For solving above-mentioned technical problem, the purpose of the present invention is to propose to the detection method in a kind of aligning roller bearing solid retainer pocket hole.
The present invention adopts the following technical scheme that for completing above-mentioned purpose
The detection method in a kind of aligning roller bearing solid retainer pocket hole, described detection method is applicable to have the detection of sloping pocket hole；First making is highly the center-diameter measurement column of H, and described center-diameter measurement column has the cylindrical section identical with pocket bore dia, and the height of cylindrical section is h, and diameter is d；The two ends of described cylindrical section are respectively provided with by the cylindrical section frustum of a cone section to convergent footpath, two ends, and the angle of inclination of frustum of a cone section is identical with the angle of inclination in retainer pocket hole, and angle of inclination is α；During measurement, center-diameter measurement column uses in pairs, in two pocket holes that two center distance measurement posts are placed on aligning roller bearing solid retainer circumference most long-chord length, the cylindrical section of center distance measurement post is made to coordinate with the Upper cylindrical pass in pocket hole fixing, the lower cone platform section of center distance measurement post is positioned at the bottom in pocket hole, and vertical with retainer end face；Then slide gauge is held in center distance measurement post lower cone platform section, measures the circumscribed circle chord length D of two center distance measurement posts2；Then again slide gauge is held in the upper cone platform section of center distance measurement post, measures the inscribed circle chord length D of two center distance measurement posts0；Then circumscribed circle diameter and inscribed circle diameter indirect calculation pocket hole inclination angle value α are utilized；Inclination angle value α is calculated by equation below:
。
The detection method in a kind of aligning roller bearing solid retainer pocket hole that the present invention proposes, the center distance measurement post adopting two ends to be circular cone structure carries out the detection in pocket hole, solve pocket hole center-diameter and the measurement problem at angle of inclination, hole, pocket hole in the lump, during owing to measuring, slide gauge contact is two parallel lines in same plane, so this measuring method precision is high, operate reproducible, the measurement technology at cutter and angle of inclination is required low, and can be intuitively, precisely measure out entity retainer pocket hole center-diameter and extrapolate angle of inclination, being particularly suited for pocket hole number is the solid cage of odd number.
Accompanying drawing explanation
Fig. 1 is the axonometric chart that the present invention measures pocket hole center-diameter and angle of inclination.
Fig. 2 is the structure top view that the present invention adds measurement column measuring center footpath when measuring odd number hole.
In figure: 1, center-diameter measurement column, 2, solid cage.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the present invention is illustrated:
As shown in Figure 1 and Figure 2, the detection method in a kind of aligning roller bearing solid retainer pocket hole, described detection method is applicable to have the detection of sloping pocket hole；First making is highly the center-diameter measurement column 1 of H, and described center-diameter measurement column 1 has the cylindrical section identical with pocket bore dia, and the height of cylindrical section is h, and diameter is d；The two ends of described cylindrical section are respectively provided with by the cylindrical section frustum of a cone section to convergent footpath, two ends, and the angle of inclination of frustum of a cone section is identical with the angle of inclination in retainer pocket hole, and angle of inclination is α；During measurement, center-diameter measurement column uses in pairs, in two pocket holes that two center distance measurement posts 1 are placed on aligning roller bearing solid retainer circumference most long-chord length, the cylindrical section of center distance measurement post is made to coordinate with the Upper cylindrical pass in pocket hole fixing, the lower cone platform section of center distance measurement post is positioned at the bottom in pocket hole, now, the measurement bus of center-diameter measurement column frustum of a cone section is vertical with retainer end face；Then slide gauge is held in center distance measurement post lower cone platform section, measures the circumscribed circle chord length D of two center distance measurement posts2；Then again slide gauge is held in the upper cone platform section of center distance measurement post, measures the inscribed circle chord length D of two center distance measurement posts0；Then circumscribed circle diameter and inscribed circle diameter indirect calculation pocket hole inclination angle value α are utilized；Inclination angle value α is calculated by equation below:
。
When pocket hole number is even number, on circumference, diametrically the circumscribed circle chord length of two center distance measurement posts is circumscribed circle diameter same in two holes of most long-chord length, and the inscribed circle chord length of two center distance measurement posts is inscribed circle diameter；
When pocket hole number is odd number, on circumference, most long-chord length is exactly connect round measured value apart from the inside and outside of two farthest pocket holes.
