Description
Technical field
The present invention relates to a kind of pivoting support, particularly relate to a kind of two rollaway type plane rotation supportings.
Background technique
The basic structure form of pivoting support is made up of inside and outside two steel rings, outer rim is enclosed within the outside of interior steel ring, on the junction plane that the outside vertical of the inner side of outer rim and interior steel ring is corresponding, respectively dig one ring-type semi-circular recesses, left and right twice groove is merged into a ring-type tubular shape raceway, filling steel ball and spacing block in raceway.Because the bonding crack of the raceway of left and right twice groove combination one-tenth is arranged by steel ball central vertical, thus compare the radial force being conducive to pivoting support, and be not too conducive to its axially loaded.
The present invention designs a kind of plane pivoting support, its structural feature is changed into by vertical setting by the bonding crack of the groove of twice up and down by steel ball center being horizontally disposed with, and raceway quantity is increased to two by one, thus greatly strengthen axial carrying capacity and the smoothness of pivoting support, special convenient axial loading demands is very high, stability requires that good main process equipment adopts.
Summary of the invention
The object of the invention is the deficiency in order to make up prior art, providing a kind of two rollaway type plane rotation supportings, to meet the technique needs of the exigent class main process equipment of thrust load.
The present invention is achieved through the following technical solutions:
A kind of two rollaway type plane rotation supportings, it is characterized in that: include outer ring, inner ring and auxiliary inner ring, described outer ring is high outside and low outside step, the step part of outer ring inwardly extends to the inward flange of pivoting support, described inner ring is high outside and low outside to be had step and is arranged on the step of outer ring, the cross section of described auxiliary inner ring is in " Z " shape, and its high portion covers inner ring step, and lower curtate is fixed on outer ring; Described outer ring is ring-type semi-circular recesses together with the horizontal integration face of inner ring respectively being dug and makes, and upper and lower two grooves are corresponding is combined into ring-type tubular shape raceway one, and in raceway one, the some steel balls one of filling, separate with spacing block between two adjacent steel balls one; Described inner ring is ring-type semi-circular recesses together with the horizontal integration face of auxiliary inner ring respectively being dug and makes, and upper and lower two grooves are corresponding is combined into ring-type tubular shape raceway two, and in raceway two, the some steel balls two of filling, separate with spacing block between two adjacent steel balls two; Described inner ring height facial planes is provided with several installation screws in order to be connected with the upper part of main frame, the point of attachment of described auxiliary inner ring and outer ring is provided with some installation through holes, and auxiliary outer ring and inner ring are by being connected and fixed by the lower part of installation through hole with main frame.
A kind of two rollaway type plane rotation supportings, it is characterized in that: include inner ring, outer ring and auxiliary outer ring, described inner ring is low inside and high outside step, the step part of inner ring outwards extends to the outward edge of pivoting support, described outer ring is low inside and high outside to be had step and is arranged on the step of inner ring, the cross section of described auxiliary outer ring is in " Z " shape, and its high portion covers outer ring step, and lower curtate is fixed on inner ring; Described inner ring is ring-type semi-circular recesses together with the horizontal integration face of outer ring respectively being dug and makes, and upper and lower two grooves are corresponding is combined into ring-type tubular shape raceway one, and in raceway one, the some steel balls one of filling, separate with spacing block between two adjacent steel balls one; Described outer ring is ring-type semi-circular recesses together with the horizontal integration face of auxiliary outer ring respectively being dug and makes, and upper and lower two grooves are corresponding is combined into ring-type tubular shape raceway two, and in raceway two, the some steel balls two of filling, separate with spacing block between two adjacent steel balls two; Described outer ring height facial planes is provided with several installation screws in order to be connected with the upper part of main frame, the point of attachment of described auxiliary outer ring and inner ring is provided with some installation through holes, and auxiliary outer ring is connected and fixed by the lower part of installation through hole with main frame with inner ring.
The outer side surface of described outer ring can arrange external gear, also can not establish.
The inner side surface of described inner ring can arrange internal gear, also can not establish.
The size of described raceway one and steel ball one can be equal with the size of raceway two and steel ball two, also can be unequal.
When within it gear is not established in side, also can interleave axle and carry out installing and using in pivoting support, but whole pivoting support can not overturn by this kind of installation form.Because the mode of loading rolling element is first directly placed in steel ball and spacing block in lower track groove, then closes upper track groove, thus filling hole, plug block need not be set and wear the filling such as pin, hole facility.Owing to being combined in fact a large oil groove of ring-type between the outer ring of backing and auxiliary inner ring and between the inner ring of backing and auxiliary outer ring, the bottom of its steel ring does not have gap, thus do not need to arrange the fueling facility such as oilhole, oil nozzle, can save the Sealing Device on top yet.
Advantage of the present invention is:
The present invention is except alternative plane bearing carries out axial operation, and can also carry out the transmission of band tooth, it is easy to process, assembling is simple, smooth running, for ease of maintenaince, long service life, very very high, the stability of convenient axial loading demands requires that good main process equipment adopts.
