Abstract
The invention relates to a needle bearing cage. The outer surface of the needle bearing cage is provided with an annular slot, and the annular slot, an elastic ring and a needle roller form an oil storage space. With the structure adopted, the needle bearing cage can increase the storage capacity of oil. Within the operating life, the lubrication of a bearing is well guaranteed, and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to bearing processing design field, especially relate to a kind of needle bearing cage with oil storage function.
Background technique
At present, can not dismantle voluntarily at the needle bearing that some occasions are used, therefore the lubricated of needle bearing must be filled with grease before installation, yet be subjected to bearing volume inside position limit, general retainer does not have the oil storage function, and its working life is on the low side, brings the certain quality influence to complete machine, increase cost of use, increased cost of production.
Summary of the invention
Technical problem to be solved by this invention provides a kind of needle bearing cage with oil storage function, is used for direction converter bearing, has solved this class bearing because of the quality problems that oil starvation causes, and the bearing of complete machine is resolved because of the problem that oil starvation fat produces.
The present invention solves the technological scheme that its technical problem takes: a kind of needle bearing cage, the outer surface of described retainer is provided with circular groove, forms oil storage space between circular groove and elastic ring and the needle roller.
Needle bearing cage has increased the storage volume of grease, has improved the working life of bearing.
The invention has the beneficial effects as follows: adopted after the said structure, the retainer of this bearing can increase the storage volume of grease, at life time inner bearing lubricated good guarantee, the working life of having improved bearing has been arranged.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a package assembly schematic representation of the present invention.
Among the figure: 1, rubber sleeve 2, elastic ring 3, needle roller 4, retainer 5, oil storage space 6, circular groove
Embodiment
A kind of as depicted in figs. 1 and 2 needle bearing cage, the outer surface of described retainer 4 is provided with circular groove 6, and the assembling back forms oil storage space 5 with elastic ring 2, needle roller 3, and retainer 4 adopts plastic production to form.
In installation process, grease will spread upon in the circular groove of the retainer 4 that installs needle roller 3, again each assembly of bearing is assembled successively, be placed in the rubber sleeve 1, because the oil storage space 5 that forms in the bearing can effectively keep grease, lubricating bearings increases the working life of bearing fully, effectively raises economic benefit of enterprises.
The foregoing description does not limit the present invention in any way all employings and is equal to and replaces or technological scheme that the mode of equivalence conversion obtains all drops in protection scope of the present invention.
Claims (1)
1. needle bearing cage, it is characterized in that: the outer surface of described retainer (4) is provided with circular groove (6), and circular groove (6) forms oil storage space (5) with elastic ring (2) and needle roller (3).
