Embodiment Construction

[0010] Such as figure 1 with figure 2 Shown is a needle roller bearing cage. The outer surface of the cage 4 is provided with an annular groove 6. After assembly, an oil storage space 5 is formed with the elastic ring 2 and the needle roller 3. The cage 4 is made of plastic.

[0011] During the installation process, the grease should be applied in the annular groove of the cage 4 where the needle roller 3 is installed, and then the components of the bearing are assembled in sequence and placed in the rubber jacket 1, because the oil storage space 5 formed in the bearing can effectively The retained grease can fully lubricate the bearing, increase the service life of the bearing, and effectively improve the economic benefits of the enterprise.

[0012] The above embodiments do not limit the present invention in any way. All technical solutions obtained by means of equivalent replacement or equivalent conversion fall within the protection scope of the present invention.

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 [0001] The invention relates to the field of bearing processing and design, in particular to a needle roller bearing cage with an oil storage function. Background technique [0002] At present, the needle roller bearings used in some occasions cannot be disassembled by themselves, so the lubrication of the needle roller bearings must be filled with grease before installation. However, limited by the space inside the bearing, the general cage does not have the oil storage function. The service life is on the low side, which brings a certain quality impact to the whole machine, increases the use cost, and increases the production cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a needle roller bearing cage with oil storage function, which is used in steering gear bearings, which solves the quality problems of such bearings caused by lack of oil, and makes the bearings of the whole machine suffe...
