Description
Technical field
The present invention relates to a kind of survey tool, and in particular to the detection means of mechanical bearing part axiality.
Background technology
Bearing part is widely used in machinery industry, and it is the important foundation parts of all kinds of mechanized equipments, it
Precision, performance, life and reliability play conclusive effect to the precision, performance, life and reliability of main frame.In machinery production
In product, bearing part belongs to high-precision product, not only needs the comprehensive support that the subjects such as mathematics, physics are theoretical, and
Need material science, heat treatment technics, Precision Machining and e measurement technology, Numeric Control Technology and effective numerical method and powerful
The subjects such as computer technology service for it, therefore bearing part is a product for representing national science and technology strength.Axle
Sliding bearing, oscillating bearing, rolling bearing, deep groove ball bearing, self-aligning ball bearing, needle bearing etc. can be divided into by structure by holding.
Sliding bearing will not divide Internal and external cycle also without rolling element, be usually to be made up of high-abrasive material, be usually used in low speed, heavy duty and filling profit
Lubricating oil and mechanical rotation position difficult in maintenance.The sliding contact surface of oscillating bearing be sphere, be primarily adapted for use in oscillating motion,
Banking motion and rotary motion.Deep groove ball bearing is most representational rolling bearing, with the other types of bearings of size identical
Compare, such bearing friction coefficient is small, limit speed is high, and simple in construction, manufacturing cost is low, precision is high, without often maintenance, and
It is a most widely used class bearing and size range is big, form is more, its substantial radial load can also bear certain axle
To load, when it is subjected only to radial load, contact angle is zero, after deep groove ball bearing is on axle, in the end-play of bearing
In the range of, the axial displacement of axle or shell both direction can be limited, therefore axially position can be made two-way, when deep groove ball bearing tool
When having larger end-play, the performance with angular contact bearing can bear larger axial load, very big in axial load
Run at high speed under operating mode, deep groove ball bearing specific thrust ball bearing more has superiority.Self-aligning ball bearing be two raceways inner ring and
Raceway is between the outer ring of sphere, is equipped with the bearing of spherical shape ball, the center of curvature and the bearing centre one in outer ring raceway face
Cause,, can be with adjust automatically, no when axle, shell are bent so with the aligning function same with automatic aligning ball bearing
Increase bearing burden, self-aligning roller bearing can bear the axial load in radial load and two directions, and self-aligning ball bearing is radially
Load-bearing capacity is big, it is adaptable to have heavy load, the situation of impact load, and inner ring internal diameter is the bearing of taper hole, can be mounted directly, or make
It is arranged on sleeve, dismounting cylinder on cylinder axis, retainer uses steel plate punched retainer, polyamide shaping self-aligning ball bearings
Suitable for bearing heavy load and shock loading, precision instrument, low noise motor, automobile, motorcycle, metallurgy, milling train, mine, stone
The industries and common mechanical etc. such as oil, papermaking, cement, squeezing sugar.
The two ends of some bearing parts are respectively provided with the hole that diameter is differed, and two holes connect to form T-shaped hole, in order to ensure two
The diameter in individual hole on same straight line, it is necessary to carry out coaxality measurement to T-shaped hole, the peace of the axiality of T-shaped hole to workpiece
Dress precision has large effect, especially in automobile industry, therefore, to assure that the T-shaped hole in workpiece possesses higher axiality,
Axiality detection is also frequently problem in machining measurement.Thousand are used to most of axiality detection of part at present
Table is divided to be detected, but amesdial can only detect columned hole, for the workpiece with T-shaped hole, then can not detect T-shaped hole
The axiality of middle macropore and aperture.
