And existing straightening-wheel, as shown in Figure 1, the assembly be made up of alignment wheel body 01 and block bearing 02, namely alignment structure is set on alignment wheel body 01 outer surface, alignment wheel body 01 is embedded in two cover block bearings 02, the outer ring of block bearing 02 and alignment wheel body 01 interference fit, make alignment wheel body 01 can rotate relative to inner ring with outer ring.Modular construction is complicated, bearing apolegamy technical requirements is high, accumulated error large, simultaneously because assembly is installed on supporting axle by two cover brearing bores, installs, changes difficulty.
Summary of the invention:
The object of the present invention is to provide a kind of bearing unit for copper pipe alignment, it is easy for installation, effectively can reduce accumulated error, improves running accuracy, and then improves copper pipe alignment precision.
For a bearing unit for copper pipe alignment, the ball that this bearing unit comprises outer ring, inner ring and is located between inner ring and outer ring, is characterized in that: the outer surface of described outer ring offers the alignment groove coordinated with described copper pipe outer surface circular arc along its circumference.
The bearing unit for copper pipe alignment of the present invention, directly on the outer ring of bearing unit, offer alignment groove, compared with conventional art, achieve the combination of the straight function of straightening-wheel sports school and bearing antifriction function, break traditions fabricated structure, makes straightening-wheel become as a whole with bearing unit, not only easy to install, also effectively can reduce accumulated error, improve running accuracy, and then improve copper pipe alignment precision.
The bearing unit for copper pipe alignment of the present invention, improves by following scheme:
Alignment groove described above is the groove of shape of roughly taking the shape of the letter U, and comprises at the bottom of a curve bath and the notch be positioned at above at the bottom of curve bath, can coordinate at the bottom of described curve bath with described copper pipe outer surface circular arc.
Be the arc length of mating with the copper pipe outer surface circular arc close to semicircle at the bottom of curve bath described above.
Notch described above is by large gradually little wealthy mouth structure, and wherein, the two side inclination several angle of notch is tangent and symmetrical with the circular arc at the bottom of described curve bath, facilitates copper pipe to enter alignment groove smoothly.
Bearing unit described above is angular contact ball bearing.
Angular contact ball bearing described above is double-row angular contact bal bearing, twice ring raceway is provided with between its inner ring and outer ring, on each ring raceway, correspondence is provided with a row ball, and the line of described ball and inner ring and outer ring ring raceway point of contact and the angle of bearing unit radial plane form a wrapping angle.
Wrapping angle described above is 25 °.
Another object of the present invention is to provide a kind of copper pipe coalignment, effectively can reduce accumulated error, improve running accuracy, and then improve copper pipe alignment precision.
A kind of copper pipe coalignment, it is characterized in that: at least comprise 3 at the spaced bearing unit for copper pipe alignment described above shifted to install of same plane, wantonly two dislocation and the alignment groove of adjacent bearing unit are relatively and jointly on copper pipe alignment direction form an alignment hole can mated with the outer surface circumference of described copper pipe.
The copper pipe coalignment of the present invention, it directly offers alignment groove on the outer ring of the bearing unit of copper pipe alignment, compared with conventional art, achieve the combination of the straight function of straightening-wheel sports school and bearing antifriction function, break traditions fabricated structure, makes straightening-wheel become as a whole with bearing unit, not only easy to install, also effectively can reduce accumulated error, improve running accuracy, and then improve copper pipe alignment precision.
The copper pipe coalignment of the present invention, improves by following scheme:
Alignment hole described above is formed on copper pipe alignment direction jointly by the bottom of the curve bath of the alignment groove of the described bearing unit shifted to install.
