Description
Technical field
The present invention relates to bearing edge guard clearance measurement decision method, and in particular to one kind is used to determine fulcrum cylindrical roller axle
Hold rib clearance measurement decision method.
Background technology
The gap on certain type No4 fulcrum cylinder roller bearings, roller end face and bearing inner race rib surface is (between abbreviation rib
Gap) 0.04~0.058mm of technical requirements, often cover bearing and assemble 28 rollers, actual length of roller deviates the deviation of nominal dimension
It is worth for 0~-0.004mm, it is desirable to which every roller rib gap should be all controlled in the range of 0.04~0.058mm, and prior art is surveyed
Computational methods are measured by the use of high-precision metric blocks as gauge, raceway developed width is measured, is measured with the vertical optical meter of 0.2um precision
The physical length of every roller, find out most long roller and most short roller in bearing, with raceway developed width subtract most long roller or
The actual size of most roller, rib clearance control is between 0.04~0.058mm.Shortcomings：Bearing parts are surveyed respectively
Amount calculates, and the overlay error of two measurement parameters be present；To the physical lengths of the whole measurement rollers of 28 rollers, measurement efficiency and
It is low, does not apply to engineering application detection.Prior art standard clearance gauge measuring method：0.04mm and 0.06mm thickness is used respectively
Standard clearance gauge control rib gap, often cover 3 rollers of bearing measuring, when checking rib gap with 0.04mm clearance gauges, roll
Body rotates different positions, and clearance gauge can pass through rolling body end surface and rib surface and enter oil duct bottom, then it is assumed that most
Small limit rib gap is qualified；When checking rib gap with 0.06mm clearance gauges, rolling element rotates different positions, and clearance gauge is not
Rolling body end surface and rib surface can be passed through, then it is assumed that greatest limit rib gap is qualified.Shortcomings：Standard clearance gauge measurement gear
Side gap error is larger, because《JJG62-2007 clearance gauge vertification regulations》Regulation, clearance gauge examine and determine for the first time allowable error should be-
Between 0.003~+0.005mm, the requirement of measurement accuracy is unsatisfactory for；3 rollers of bearing measuring are often covered, whole rollers are not entered
Row measurement, it is also possible to measurement error be present.
The content of the invention
The present invention judges to use survey calculation method to solve cylinder roller bearing rib clearance measurement in the prior art
In the presence of the overlay error of two measurement parameters；To the physical lengths of the whole measurement rollers of 28 rollers, measurement efficiency and its low,
Inapplicable engineering application detection, it is larger using standard clearance gauge measuring method rib gap error, and measurement error be present
Problem, and then provide a kind of for determining fulcrum cylinder roller bearing rib clearance measurement decision method.
