Abstract
The utility model relates to a non-flange bearing with two rows of rollers, which is a matching bearing for rolling machines and heavy machinery in metallurgy industry, composed of an outer ring, an inner ring, two cages and two rows of rolling bodies. The external layer of the bearing is provided with the outer ring; the internal layer is provided with the inner ring; the inner ring and the outer ring are annular; the two cages and the two rows of rolling bodies are arranged between the inner ring and the outer ring; the rolling bodies are arranged on the cages and are closed on the cages by the retainer ring on each of the cages. The utility model adopts that the contact performance of the two rows of short rolling bodies and rolling ways is improved to cause the limit speed of the bearing to increase; the service life of the utility model is prolonged by more than one time, compared with a long roller bearing.
Description
The utility model double-row roller bearing without flange is the self-contained bearing of metallurgy industry rolling machinery, heavy machinery.
Present domestic metallurgical machinery is a large amount of, and what adopt is " 4 " type long cylindrical roller bearing, and it is made up of an outer ring, inner ring, riveted retainer and a row long cylinder roller.This bearing roller is long, and the contact performance of roller and raceway is poor, and is all lower with respect to its ability to work coefficient of cylindrical roller bearing and limit revolution.Retainer is to be formed by two back-up rings and several pillar riveteds, and the strength phenomenon is twisted in the normal appearance of retainer during owing to the Zhi Zhuchang riveted, and skew easily takes place roller when rotated.Be the guide rolls rotation, the roller two ends have pivot, and its manufacturability is poor, and the roller pivot easily ruptures during rotation.This bearing power that in use is hit is bigger, and therefore riveted pillar limited amount the riveted point often occurs to strut the phenomenon that causes retainer to destroy, and above-mentioned various factors has all reduced the working life of bearing.
The utility model purpose provides a kind of double-row roller bearing without flange, can replace " 4 " type long cylindrical roller bearing, overcomes above-mentioned shortcoming.
The utility model double-row roller bearing without flange content Description:
The utility model double-row roller bearing without flange is made up of an outer ring, inner ring, two retainers and biserial rolling element, and it is characterized in that: the skin of bearing is an outer ring, is ring, play supporting role; Nexine is an inner ring, is ring, rotates with milling train axle drive fit.Be two retainers and two row's rolling elements between the inside and outside circle, rolling element is enclosed on the retainer by the back-up ring on the retainer after being contained on the retainer, and roller can not be separated with retainer.
The utility model double-row roller bearing without flange, the rolling element shorten length, rolling element and raceway contact performance improve, and bearing limit revolution and ability to work coefficient all are improved, assembling back roller content 100% has avoided retainer to twist the phenomenon of strength roller skew.This bearing roller does not have the pivot at two ends, and is easy to process, eliminated the phenomenon of roller pivot fracture.In addition, retainer riveted point increases, and is identical with the roller number, increased riveted intensity, and can be enhanced about more than once its working life.
Embodiment:
Fig. 1 is the double-row roller bearing without flange structural representation
Among the figure: outer ring 1 has 1, and is circular, play supporting role; Rolling element 2 has two row, short columnar roller; Inner ring 3 has 1, ring, there are two for the ring-type solid cage with the milling train axle drive fit retainer 4 that rotates together with the axis, axially equidistantly distributing rolling element pocket hole at retainer, isolate platform for one between the two pocket holes, isolate platform and link to each other with at the bottom of the pocket hole, rolling element is enclosed on the retainer by the back-up ring on the retainer, rolling element and retainer are become one can not be separated, and is contained in then in the raceway between the Internal and external cycle.
Claims (2)
1, a kind of double-row roller bearing without flange is made up of an outer ring, inner ring, two retainers and biserial rolling element, and the skin that it is characterized in that bearing is an outer ring, is ring; Nexine is an inner ring, is ring; Be two retainers and two row's rolling elements between the inside and outside circle, rolling element is enclosed on the retainer by the back-up ring on the retainer after being contained on the retainer.
2, double-row roller bearing without flange according to claim 1, it is characterized in that said retainer has two, be the ring-type solid cage, axially equidistantly distributing rolling element pocket hole at retainer, isolate platform for one between the two pocket holes, isolate platform and link to each other with at the bottom of the pocket hole.
