Background technology
At present, robot, radar, medical instruments field critical piece bearing requirements possess high accuracy, high rigidity, can be with essence
Certainly position（Moment of friction uniformity is good）Performance.The crossed roller bearing of double half inner rings that the utility model is related to, 4 points connect
Touch ball bearing, bearing ring full quenching steel making, multi-configuration steel plate retainer, with conventional cross roller, four penalty kick turntable shafts
Hold and compare, hole, the stopper of lasso arming rolling element on this kind of bearing arrangement are eliminated because stopper factor is to bearing accuracy, friction
The influence of moment, can obtain running accuracy high, the good uniformity of friction moment；The structure of subdivision can arrange steel plate structure
Retainer, load more rolling elements, and make the speed ability that bearing possessed, meanwhile, lasso causes bearing without soft ribbons
Bearing capacity improves a lot, and this class bearing list set product can bear radial load can bear axial load, power of toppling again
Square, beneficial to the lightweight for realizing whole machine, while bearing possesses the good uniformity of running accuracy high, high-mechanic, moment of friction
Feature, this class bearing is increasingly used in robot, radar, medicine equipment etc. the field for being accurately positioned requirement.
Double half inner-ring bearings that the utility model is related to, what the lasso of its pair half had uses connecting bolt part, the product also having
There is no connecting bolt.Aborning, traditional crossed roller, the clearance measurement of 4 ball slewing bearings is used and presss from both sides ball Wall-Thickness Method, rolling
The road size direct method of measurement, friction moment mensuration calculate, evaluate the clearance of bearing, to double half inner-ring bearings, inner ring for point
It is release, then cannot realize.
The content of the invention
The purpose of this utility model is to provide a kind of double half inner ring crossed roller bearing, four-point contact ball bearing clearances
Detection means, both can check bearing finished product clearance, can be used in inter process again, judge part raceway processing dimension whether meet
Clearance requirement.
The purpose of this utility model can adopt the following technical scheme that to realize：It includes base and gland, clamp nut, survey
Amount end cap, measurement table, the base middle part is cylinder, and its bottom has an end edge, end edge with diameter greater than middle part cylinder
The diameter of body, cylinder height is less than bearing height, and cylinder top is provided with threaded post；Gland is enclosed within the threaded post of base
On, clamp nut is fastened in threaded post, and gland is pressed against on bearing inner sleeve upper half inner ring, measured bearing upper half inner ring and
Lower half inner ring is enclosed within the cylinder external diameter of the base between gland and end edge；Described measurement end cap is located at the top of gland,
Measurement table is arranged on the top of gland.
Cylinder external diameter and measured bearing internal diameter in the middle part of the base are interference fits.
The measurement end cap is in inverted cup type, and ring-shaped step, the measurement end tops middle setting are set in rim of a cup
One boss, boss center line overlaps with measured bearing axis；Described measurement table is arranged on the center of boss.
The measurement end tea cup with a cover choma shape stepped portions internal diameter is enclosed within bearing outside external diameter, and it is matched somebody with somebody and is combined into interference fits,
On measured bearing overcoat upper surface contacts, the small internal diameter for measuring end cap is less than bearing outside diameter, more than bearing for step end face part
External diameter.
The utility model simple structure is easy to detect, effective.Measurement table magnetic force dial framework or other servicing units are fixed,
Indicator perpendicular contact measurement end lid upper boss centre.During detection, bearing inner race is compressed by nut, gland, apply outer
Power, moves up and down bearing outside（Measurement end cap can simultaneously be moved up and down with bearing）, measurement table display numerical value is the axial direction of bearing
Clearance, so as to realize the class bearing clearance detect, in real work, it is measurable for several times（General 2 ~ 3 times）, it is fixed to average
It is the clearance of bearing.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In figure：1st, base, 2, gland, 3, clamp nut, 4, measurement end cap, 5, measurement table, 6, in measured bearing upper half
Circle, 7, measured bearing outer ring, 8, measured bearing lower half inner ring.
Specific embodiment
With reference to accompanying drawing 1, specific embodiment of the utility model is illustrated：
As shown in Figure 1：The utility model includes base 1 and gland 2, and clamp nut 3 measures end cap 4, and measurement table 5 is described
The middle part of base 1 is cylinder, and its bottom has end edge, and the diameter with diameter greater than base cylindrical body of end edge, base cylindrical body is high
Degree is less than bearing width（Or height）, cylinder top is provided with threaded post, and gland 2 is enclosed within threaded post, and clamp nut 3 is fastened
In threaded post, gland 2 is pressed against on bearing inner sleeve upper half inner ring 6, bearing two halves inner ring 6,8 is enclosed within the cylinder of base 1
