Description
Technical field
The present invention relates to a kind of pivoting support, relate in particular to a kind of two rollaway type plane rotation supportings.
Background technique
The basic structure form of pivoting support consists of inside and outside two steel rings, outer rim is enclosed within the outside of interior steel ring, in the outside vertical of the inboard of outer rim and interior steel ring on corresponding junction plane, respectively dug the ring-type semi-circular recesses one, left and right twice groove is merged into a ring-type tubular shape raceway, filling steel ball and spacing block in raceway.The bonding crack of the raceway become due to left and right twice groove combination arranges by the steel ball central vertical, thereby relatively is conducive to the radial force of pivoting support, and not too is conducive to its axially loaded.
The present invention designs a kind of plane pivoting support, its structural feature is that the bonding crack of the groove of twice up and down by the steel ball center is changed into and being horizontally disposed with by vertical setting, and raceway quantity is increased to two by one, thereby greatly strengthened axial carrying capacity and the smoothness of pivoting support, special convenient axial load requirement is very high, stability requires good main process equipment to adopt.
Summary of the invention
The objective of the invention is in order to make up the deficiency of prior art, provide 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 always, 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 " Z " shape, and its high section covers the inner ring step, and lower curtate is fixed on outer ring; On the horizontal integration face of described outer ring and inner ring, respectively dig make together with the ring-type semi-circular recesses, the corresponding ring-type tubular shape raceway one that is combined into of upper and lower two grooves, the some steel balls one of the interior filling of raceway one, separate with spacing block between two adjacent steel balls one; On the horizontal integration face of described inner ring and auxiliary inner ring, respectively dig make together with the ring-type semi-circular recesses, the corresponding ring-type tubular shape raceway two that is combined into of upper and lower two grooves, the some steel balls two of the interior filling of raceway two, separate with spacing block between two adjacent steel balls two; The high facial planes of described inner ring is provided with several installation screws that divide the use that links in order to the top with 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 with the lower part of main frame by through hole is installed.
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 always, 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 " Z " shape, and its high section covers the outer ring step, and lower curtate is fixed on inner ring; On the horizontal integration face of described inner ring and outer ring, respectively dig make together with the ring-type semi-circular recesses, the corresponding ring-type tubular shape raceway one that is combined into of upper and lower two grooves, the some steel balls one of the interior filling of raceway one, separate with spacing block between two adjacent steel balls one; On the horizontal integration face of described outer ring and auxiliary outer ring, respectively dig make together with the ring-type semi-circular recesses, the corresponding ring-type tubular shape raceway two that is combined into of upper and lower two grooves, the some steel balls two of the interior filling of raceway two, separate with spacing block between two adjacent steel balls two; The high facial planes in described outer ring is provided with several installation screws that divide the use that links in order to the top with 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 and inner ring are connected and fixed with the lower part of main frame by through hole is installed.
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 equate with the size of raceway two and steel ball two, also phase not
Deng.
Does not establish in the situation of gear side within it, can in pivoting support, interleave axle yet and installed and use, but this kind of installation form can not be by whole pivoting support upset.Because the mode of loading rolling element is first steel ball and spacing block directly to be placed in lower raceway groove, the upper raceway groove that closes, thereby filling hole, plug piece needn't be set and wear the filling facilities such as pin, hole.Owing between the outer ring of backing and auxiliary inner ring and between the inner ring of backing and auxiliary outer ring, being combined in fact a large oil groove of ring-type, the bottom of its steel ring does not have gap, thereby do not need the fueling facilities such as oilhole, oil nozzle are set, also can save the Sealing Device on top.
Advantage of the present invention is:
The present invention, except alternative plane bearing carries out axial operation, can also be with the tooth transmission, and it is easy to process, assembling is simple, smooth running, for ease of maintenaince, long service life, very convenient axial load requires very high, stability to require good main process equipment to adopt.
