Abstract
A measuring method of the lock amount of an angle contact ball bearing ring uses a special bearing check instrument to measure the lock amount of the angle contact ball bearing ring. The basic principle is to measure through a comparison method: (I) firstly, a standard ring in a shape totally the same as the checked ring is selected and put on a D714 bearing check and measuring instrument to be adjusted; all positioning and measuring supporting points of the D714 bearing check instrument are adjusted, so that benchmark supporting points, the positioning supporting points and elastic hold-down supporting points are at the same height and totally on the center or the center line of a channel; the measuring supporting points are as close to the benchmark points as possible; after the instrument is adjusted and positioned, the standard piece is removed, and the part can be measured. (II) after the bearing ring is arranged, a measurement meter can immediately read the lock amount of the ring. The ring rotates for a round, and the change range of the lock amount of the whole ring can be read. In this way, the lock amount of the angle contact ball bearing ring can be measured. The method has the advantages of accurate, convenient and fast measurement, etc.
Description
Affiliated technical field
The present invention relates to a kind of bearing ring detection technique field, relate in particular to a kind of angular contact ball bearing ferrule locking amount measurement method.
Background technology
Angular contact ball bearing is extensive use of in social every field, and the quality of angular contact ball bearing quality directly has influence on each the normal operation and economic benefit of going of society.The angular contact ball bearing ferrule locking amount value has a significant impact product quality, angular contact ball bearing when assembling, need the heating outer ring that it is risen greatly, above the designed hold depth value of lasso, it is assembled into one, drop to normal temperature after, bearing ring can not separate.The hold depth value must be controlled within the limits prescribed through the accurate Calculation design, guarantees the easy assembling of bearing and can not separate, not damage bearing parts.
Traditional measuring method is: measurement instrument is surveyed on the lasso raceway groove, and mobile then lasso is observed instrument indication value, judges bottom of trench to minimum value shown in the instrument, and mobile again lasso is sought the hold depth maximal value, and the difference of calculating two values obtains the hold depth value.The shortcoming of traditional measurement method is: (1) measuring principle is correct, but measurement mechanism is irregular, and lasso location and lasso move manually and carry out during measurement, make measurement result be easy to generate artificial error.(2) minimum value and the maximal value of reading in the measurement is in the moving process of lasso, and instrument indication value is read in constantly changing, and influences the accuracy of reading.(3) the one-shot measurement process can only be measured the hold depth of a point on the lasso circumference, if measure the variation on the hold depth circumference, then wants multimetering, and work in-process is difficult to measure.(4) measuring process is long, and labour intensity is big, and production efficiency is low.
Summary of the invention
In order to overcome the deficiencies in the prior art, the technical problem to be solved in the present invention is a kind of measuring method that can measure angular contact ball bearing ferrule locking amount fast, reduce labour intensity, enhance productivity of exploitation.
For achieving the above object, the present invention adopts following technical scheme:
A kind of angular contact ball bearing ferrule locking amount measurement method, use the special bearing inspection apparatus to measure angular contact ball bearing ferrule locking amount, its ultimate principle is a comparative method for measuring: (one) at first selects for use and the identical standard lasso of measured sleeve loop-shaped, be put on the D714 bearing check measurement instrument and transfer, adjusting D714 bearing detector respectively locatees fulcrum and measures fulcrum, make the benchmark fulcrum, the location fulcrum, the height unanimity of elastic compression fulcrum, and fully on raceway groove center or center line, allow and measure fulcrum as far as possible near reference point, behind the instrument adjustment location, take off standard component, can measure part.(2) after bearing ring was put, meter can be read ferrule locking amount.Lasso is rotated a circle, can read the variation range of whole ferrule locking amount.Thereby finish the measurement of diagonal angle contact ball bearing ferrule locking amount.
On inner ring, described measuring method adopts said method to carry out hold depth with D724 bearing detector and measures for hold depth.
Because bearing ring is through Precision Machining, its shape can be consistent with standard component.Measuring error is minimum, can ignore.The method has overcome the shortcoming of traditional measurement method, and it is accurate, convenient, fast to measure.
Owing to adopted technical scheme as mentioned above, the present invention has following good effect:
This method can be measured angular contact ball bearing ferrule locking amount fast, reduces labour intensity, enhance productivity, and measures advantages such as accurate, convenient, fast.

Embodiment
Embodiment 1:
With 7213AC is example, (1) at first with the good outer ring hold depth standard component of calibrating, be put on the D714 bearing check measurement instrument, adjust instrument, adjusting D714 bearing detector respectively locatees fulcrum (5) and measures fulcrum (2), make the height unanimity of benchmark fulcrum (1), location fulcrum (5), elastic compression fulcrum (3), and fully on raceway groove center or center line, allow and measure fulcrum (2) as far as possible near reference point (1); 7213AC standard component hold depth is 0.16
+ 0.01, behind the instrument adjustment location, take off standard component, can measure part.(2) hold depth design calculated value in 7213AC outer ring is 0.16
-0.02, after bearing ring was put, meter can be read ferrule locking amount.Measured value is in scope of design, and the hold depth value is qualified, and lasso is rotated a circle, and can read the variation range of whole ferrule locking amount.Thereby finish the measurement of diagonal angle contact ball bearing ferrule locking amount.
