Abstract
The invention discloses a method for measuring the groove position of an inner bearing ring, which comprises the following steps of: a, preparing a micrometer, and arranging a measuring ball of which the diameter d is the same with the radius R of a measured groove at the measuring end of the micrometer; b, measuring the end surface height H real of a measured inner bearing ring; c, measuring the assembly surface height C real of the measured inner bearing ring; d, adjusting the distance E between the lower end of the measuring ball of the micrometer and a measuring plane according to a theoretical value A0 of the groove and the end surface height H real of the measured inner bearing ring, wherein the E=(H real-A0)-d/2; e, putting the measured inner bearing ring on the measuring plane, making the arc of the groove completely match with that of the measuring ball of the micrometer, and obtaining the reading X real of the micrometer; f, calculating the real groove position A real of the measured inner bearing ring, wherein the A real=H real-X real; and g, calculating the real groove assembly position B real of a measured bearing, wherein the B real=X real-C real. The method has the characteristics of simplicity for measurement, convenience for operation and high detection accuracy.
Description
Technical field
The invention belongs to bearing detection technique field, especially relate to the measuring method of a kind of bearing inner sleeve ditch position.
Background technology
The bearing industry of China development in recent years rapidly, but domestic measuring technique to bearing is also relatively backward, especially to the measuring method of bearing inner sleeve ditch position, and bearing inner sleeve ditch position is one of important test item of bearing; At present, domestic measurement to bearing inner sleeve ditch position generally all is to adopt the testing staff to go out actual ditch place value and practical set ditch place value with kind of calliper; Yet, because testing staff's difference, it is also different that it measures gimmick, the actual ditch place value of measuring at last and the bigger error of existence of practical set ditch place value, thereby can cause the bearing inner sleeve of producing can't be up to standard, badly influence the qualification rate of the bearing inner sleeve of producing, also greatly reduce the production efficiency of enterprise simultaneously, also increased the production cost of enterprise to a certain extent.
Summary of the invention
To the objective of the invention is the degree of accuracy bearing inner sleeve ditch position measured in order improving, the measuring method of a kind of bearing inner sleeve ditch position to be provided.
For this reason, the technical solution adopted in the present invention is: the measuring method of bearing inner sleeve ditch position is characterized in that comprising the steps:
A prepares 1,000 fens instrument, and its measuring junction is made as the survey ball, and the diameter d of surveying ball is identical with measured raceway groove radius R;
B measures the end face height H of overlapping in the measured bearing
Real
C measures the fitting surface height C that overlaps in the measured bearing
Real
D is according to the theoretical value A of ditch position

The ditch position of bearing inner sleeve of the present invention is meant the distance of the distance of center circle bearing inner sleeve end face of bearing inner sleeve raceway groove circular arc; The assembling ditch position of described bearing inner sleeve is meant the distance of the distance of center circle bearing inner sleeve fitting surface of bearing inner sleeve raceway groove circular arc.
Compared with prior art, measuring method of the present invention is simple, and the testing staff operates also comparatively convenient; Because ditch position and assembling ditch position are difficult to direct measurement, the present invention calculates by measuring other parameters, and the institute directly numerical value of measurement is the precision that can reach very high, has so just improved measuring accuracy; The measuring junction of thousand fens of instrument is made as the survey ball, and the diameter d of surveying ball is identical with measured raceway groove radius R, and it mainly is in order to fit like a glove with the circular arc of above-mentioned raceway groove, can to make thousand fens instrument measure more accurate data X
RealThereby, by formula A
