Abstract
The utility model belongs to a bearing component and discloses a large ball bearing which is combined by sections. One end of each section is provided with a convex connecting sheet (5), and the other end is provided with a concave hole which can be fastened with the connecting sheet (5). The utility model is integrated by fastening head to tail of the sections. The sections have no gap, and operational noise is quite low. The noise of the integral machine is less than 70dB, and rotation accuracy is of PS grade. Meanwhile, the utility model can reduce fault rate and prolong service life.
Description
Affiliated technical field
The utility model belongs to bearing part, mainly proposes a kind of large-scale ball bearing retainer.
Background technique
At present, as gamma knife, CT machine, X-ray production apparatus, be widely used in the medical equipment, very high to performance, the life requirements of associated self-contained bearing.The main feature of this class bearing is: bearing boundary dimension is big, and wall thickness belongs to large-sized thin-wall bearing.Its large-sized nylon cages limits because of mould, still there is not overall structure, be segmented, but do not connect between each section, cause between each retainer and exist the gap, each section collision produces noise in operation process, must influence the level of noise of bearing, influences the life-span of retainer and the precision of complete machine running simultaneously.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of large-scale ball bearing retainer, and noise reduced when it can make bearing operation, improves precision, prolongs bearing life.
The utility model purpose adopts following technological scheme to realize: described retainer adopts segmented to be formed by connecting, and each section end is provided with a connecting sheet that outwards protrudes, and the other end is provided with a shrinkage pool that can interlock with connecting sheet.
Because the utility model employing segmentation is linked closely from beginning to end to link to each other and is formed as a whole structure, make to constitute between each segmentation of retainer and do not have the gap substantially, running noise is extremely low, it can make the noise of complete machine be lower than 70dB, running accuracy reaches the P5 level, simultaneously, reduce rate of fault, prolonged its working life.
Description of drawings
Accompanying drawing 1 is a kind of large size bearing structural representation.
Accompanying drawing 2 is the utility model structural representation.
Among the figure, 1, the outer ring, 2, inner ring, 3, steel ball, 4, retainer, 5, connecting sheet, 6, connect shrinkage pool.
Embodiment
In conjunction with the accompanying drawings, further describe embodiment of the present utility model:
Be a kind of large size bearing as shown in Figure 1, mainly constitute by outer ring 1, inner ring 2, steel ball 3, retainer 4.
Retainer 4 as shown in Figure 2 adopts segmenteds to be formed by connecting, and each section end is provided with a connecting sheet 5 that outwards protrudes, and the other end is provided with a shrinkage pool 6 that can interlock with connecting sheet 5.Each segmentation interlocks from beginning to end and forms an integral cage 4.
