Abstract
The utility model discloses a measuring column for the central diameter of a cage pocket hole of a self-aligning roller bearing entity. The diameter of an upper section column (2) of the measuring column (1) is larger than that of a lower section column (3); and a conical transition section (4) is arranged between the upper section column (2) and the lower section column (3) of the measuring column. The measuring column has ingenious design and reasonable conception; according to the shape of the cage pocket hole of the self-aligning roller bearing entity and the processing characteristics of the pocket hole, in order to measure the central diameter of the product accurately, and consider the convenience and operability of use on production site, the measuring column mode is adopted to measure the central diameter of the cage pocket hole of the self-aligning roller bearing entity, thus being capable of intuitively and accurately measure the size of the central diameter of the cage packet hole of the entity, having not only high measuring accuracy, but also simple structural design, easy manufacture, convenient use for production site and strong repeated operability and being suitable for being promoted.
Description
Technical field
The utility model belongs to retainer pocket hole measurement device technique field, and what relate generally to is footpath, center, a kind of self-aligning roller bearing solid cage pocket hole measurement column.
Background technology
The center, pocket hole of self-aligning roller bearing solid cage directly is important parameters very in the retainer processing, the processing precision direct influence assembling in footpath, center, pocket hole, if center, pocket hole footpath machining precision error will cause rolling body to skid, fall roller and serious quality problems such as stuck.So serviceability of the processing precision direct influence finished product bearing in footpath, center, self-aligning roller bearing solid cage pocket hole.
Measurement to footpath, center, self-aligning roller bearing solid cage pocket hole at present mainly contains following several method:
Examination cover method: the retainer examination cover with processing, fall roller flexibly and not with the sensation rotation, just think that footpath, center, retainer pocket hole is qualified.This method is more backward, and measuring error is big, and accuracy is lower.
Footpath, vertex (vertices) center, pocket hole mensuration: center, pocket hole directly is converted into vertex (vertices) center, pocket hole numerical value directly, measures then.Because what the vertex (vertices) center was directly measured is a vertex (vertices) point, be difficult to measuring point is placed on the vertex (vertices) accurately, not only measurement is not easy to operate, and measuring error is big, and accuracy is lower.
The stick harness mensuration: be made up of stick harness and small column, two stick harnesses that use in pairs during measurement are placed on respectively in two pocket holes on the retainer diametric(al), measure the distance of two small columns on the stick harness.Because each measurement all needs centering one secondary flat, and the plane of centering is careless slightly in measuring process then has mobilely, and not at all easy plane that finds also needs again spended time to look for again.Operation is repeatable relatively poor, and measuring accuracy also is subjected to certain influence.
In actual applications, generally adopt two kinds of measuring methods to corroborate each other, guarantee the machining precision in footpath, center, pocket hole.
Summary of the invention
The purpose of this utility model is to propose footpath, center, a kind of self-aligning roller bearing solid cage pocket hole measurement column.This measurement column is not only easy to use, and repetitive operation is strong, and the measurement accuracy height.
For achieving the above object, the technical scheme that the utility model is taked is: the epimere column diameter of measurement column is greater than the diameter of hypomere post, has the tapering transition section between the epimere post of measurement column and hypomere post.
The utility model design is ingenious, reasonable idea, according to self-aligning roller bearing solid cage pocket hole shape and pocket hole machining characteristics, for footpath, accurate measurement products center, and consider convenience and the operability that use the production scene, adopt the mode of measurement column to measure footpath, center, self-aligning roller bearing solid cage pocket hole, can intuitively, accurately measure the size in footpath, center, solid cage pocket hole, measurement accuracy height not only, and structural design is simple, and is easy to manufacture, makes things convenient for the use of production scene, repetitive operation is strong, is suitable for promoting.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 uses synoptic diagram for the utility model.
Among the figure: 1, measurement column, 2, the epimere post, 3, the hypomere post, 4, the tapering transition section, 5, retainer pocket hole.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1, the measurement cylinder in footpath, center, the described self-aligning roller bearing solid cage of present embodiment pocket hole is a column structure, and material is: GCr15, hardness is: 62-65HRC.Epimere post 2 diameters of this measurement column 1 are greater than the diameter of hypomere post 3, have tapering transition section 4 between the epimere post of measurement column and hypomere post.The length of tapering transition section 4 is determined with bevel protractor control by the ramp angles of hypomere column diameter and tapering transition section.Tapering transition section angle has strict tolerance limits during fabrication, measures with coelosphere.The baseplane of measurement column 1 and axis normal, for being convenient for measuring, the length of tapering transition section is generally all greater than 5mm.
Measurement column uses (as shown in Figure 2) in pairs during measurement, and measurement column 1 is placed in the pocket hole along retainer pocket hole 5 central axial direction.Two measurement columns are placed on respectively in two pocket holes on the retainer diametric(al).Measurement column epimere post is by fixed apertures on the pocket hole, and measurement column hypomere post 3 drops on bottom, pocket hole.After measurement column was put into the pocket hole, tapering transition section 4 length part was vertical with the retainer end face, and the distance of measuring between two slopes is footpath, center, self-aligning roller bearing solid cage pocket hole.Be converted into footpath, center numerical value indirectly.
Claims (2)
1. center, self-aligning roller bearing solid cage pocket hole footpath measurement column, it is characterized in that: the diameter of the epimere post (2) of measurement column (1) is greater than the diameter of hypomere post (3), has tapering transition section (4) between the epimere post (2) of measurement column and hypomere post (3).
2. footpath, center, self-aligning roller bearing solid cage according to claim 1 pocket hole measurement column, it is characterized in that: the length of described tapering transition section (4) is greater than 5mm.
