Abstract
The invention relates to a grease storing device of a grease lubricating angular contact ball bearing retainer. The grease storing device comprises a retainer main body, and is characterized in that one side or two sides of the external diameter wall surface of the retainer main body is /are provided with a grease storing groove, thereby improving the grease storing space; the grease storing groove on the retainer can ensure the grease storing space to be enlarged by 5%, especially the grease storing groove is closed to a rolling element and a raceway, and the lubricating grease can enter into the rolling area easily, thereby achieving an effective lubricating effect, i.e., the lubricating grease in the grease storing groove is effective lubricating grease; and the retainer of the structure can be used for prolonging the service life of a bearing by about 10%.
Description
Technical field
The present invention relates to the grease lubrication angular contact ball bearing cage, particularly relate to the depot fat device of grease lubrication angular contact ball bearing cage.
Background technique
In the angular contact ball bearing of high speed grease lubrication, the effect of retainer is most important, in five big parts of bearing (outer ring, inner ring, steel ball, retainer, lubricating grease), selects for use to material from structure, shape, and the variation of retainer is maximum.It has directly determined the performance such as speed, vibration, noise of bearing.Its life-span of the ball bearing of grease lubrication says to be exactly the working life of lubricating grease in bearing to a certain extent, a large amount of tests and use condition explanation, and the bearing of grease lubrication, fat lose the lubrication rear bearing and have also just damaged.Therefore, how increasing the reserves of lubricating grease in the bearing, is to prolong the grease lubrication angular contact ball bearing key technology in working life.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, a kind of depot fat space of setting up in retainer is provided, make close rolling element in depot fat space and raceway limit in the retainer simultaneously, make lubricating grease enter scroll zones easily, play the depot fat device of the grease lubrication angular contact ball bearing cage of effectively lubricating effect.
The technological scheme of the depot fat device of grease lubrication angular contact ball bearing cage of the present invention: comprise the retainer main body, it is characterized in that the system grease storage groove is opened in a side or the both sides of the external diameter wall of described retainer main body.
The depot fat device of grease lubrication angular contact ball bearing cage of the present invention, the system grease storage groove is opened in a side or both sides at the external diameter wall of retainer main body, increased the depot fat space of bearing, grease storage groove on this retainer can make the depot fat space of bearing increase 5%, particularly grease storage groove distance scroll body and raceway are extremely near, its lubricating grease very easily enters scroll zones, and play the effective lubricating effect, be that the interior lubricating grease of grease storage groove is effectively lubricating fat, adopt the retainer of this structure, can make the life-span of bearing improve about 10%.
The depot fat device of grease lubrication angular contact ball bearing cage of the present invention, its described retainer main body is that metallic material or phenolic aldehyde cloth tube material are made.Adopt phenolic aldehyde cloth tube material, wear-resisting property with good high speed rotating.

Fig. 2 is a grease lubrication angular contact ball bearing cage schematic representation of the present invention.
Embodiment
The present invention relates to the depot fat device of grease lubrication angular contact ball bearing cage, as shown in Figure 1, comprise retainer main body 1, system grease storage groove 11 is opened in the side or the both sides that it is characterized in that the external diameter wall of described retainer main body 1,12, the system grease storage groove is opened in a side or both sides at the external diameter wall of retainer main body, increased the depot fat space of bearing, grease storage groove on this retainer can make the depot fat space of bearing increase 5%, particularly grease storage groove distance scroll body and raceway are extremely near, its lubricating grease very easily enters scroll zones, and play the effective lubricating effect, be that the interior lubricating grease of grease storage groove is effectively lubricating fat, adopt the retainer of this structure, can make the life-span of bearing improve about 10%.Its described retainer main body 1 is that metallic material or phenolic aldehyde cloth tube material are made, adopts phenolic aldehyde cloth tube material, the wear-resisting property with good high speed rotating.
Claims (2)
