Description
Technical field
The utility model belongs to technical field of bearings, and in particular to a kind of high speed wire rod finishing block cone mating cylindrical roller of case
Bearing.
Background technology
High speed wire rod finishing block is the one of the important signs that for weighing national steel and iron manufacturing industry level and technical merit.In recent years
Come, with the upgrading of high speed wire rod finishing block, improves, high speed also increasingly harsher to its mating bearing technology index request
Wire finishing mill bores the mating cylinder roller bearing of case, and with high content of technology, high precision machining, vibration values are small, added value is high, it is desirable that
There is higher comprehensive performance in operation.
Invention content
To achieve the above object, the utility model provides a kind of high speed wire rod finishing block cone mating cylinder roller bearing of case,
Including inner ring, outer ring, rolling element and retainer；Dovetail groove is arranged in the circumferencial direction of the retainer internal diameter, and the dovetail groove is set
It sets on retainer window beam, dovetail groove is corresponded with window beam, and the four corners in retainer pocket hole are set as fillet, the guarantor
It holds and is provided with lock point on frame.
Further, the lock point is arranged on the outer diameter direction in retainer pocket hole, and lock point is contacted with window beam, each pocket hole
Four lock points of upper setting, four lock points in same pocket hole match the rolling element positioned in the pocket hole.
Further, the fillet in retainer pocket hole is great circle corner structure, the arc surface protrusion retainer pocket hole of fillet
Four sides.
Further, the retainer outer surface is silver-plated.
Further, the retainer is an integral structure.
Further, in the axis of cone of the cylinder roller bearing for high speed wire rod finishing block cone case.
The beneficial effects of the utility model are：Simple in structure, reasonable design improves the intensity of retainer, ensure that axis
The effective operation held.

In figure：1, inner ring, 2, outer ring, 3, rolling element, 4, retainer, 5, dovetail groove, 6, retainer window beam, 7, protect
Hold frame pocket hole, 8, Rouno Cormer Pregrinding Wheel, 9, lock point.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings, in a kind of axis of cone for high speed wire rod finishing block cone case
High speed wire rod finishing block bores the mating cylinder roller bearing of case, including inner ring 1, outer ring 2, rolling element 3 and retainer 4；The holding
Dovetail groove 5 is arranged in the circumferencial direction of 4 internal diameter of frame, and the dovetail groove 5 is arranged on retainer window beam 6, dovetail groove 5 and window beam 6 one
One corresponds to, and 5 structure of dovetail groove alleviates retainer weight, is conducive to bearing and steadily effectively operates, and increase lubrication；It is described
The four corners in retainer pocket hole 7 are set as fillet 8, and lock point 9 is provided on the retainer.
The lock point 9 is arranged on the outer diameter direction in retainer pocket hole 7, and lock point 9 is contacted with window beam 6, is set on each pocket hole 7
Four lock points are set, four lock points in same pocket hole match the rolling element positioned in the pocket hole.In retainer pocket hole
" 4 lock points " design, ensures that rolling element is easily packed into from retainer outer diameter, does not scratch rolling element surface, and rolling element is in the running
It will not fall out bearing.
The fillet in retainer pocket hole is the grinding undercut of 8 structure of Rouno Cormer Pregrinding Wheel, the arc surface protrusion retainer pocket hole of fillet
Four sides.First, under the operating mode to run at high speed, Rouno Cormer Pregrinding Wheel designs the inlet that can increase lubricating oil, increases rolling
The lubrication of body and raceway；Secondly, the mutually deserved contact area for reducing four wall and rolling element working surface of pocket hole, rolls to reduce
The friction of body and pocket hole.
4 outer surface of the retainer is silver-plated.Silver coating not only acts as the effect of increasing heat dissipation, can even more increase bearing from profit
Sliding effect.
The retainer is an integral structure.Retainer uses high intensity bearing steel material, integrated retainer that can expire
Sufficient bearing is under severe duty to the intensity requirement of retainer.
