Abstract
A grease storage device of a grease lubrication angular-contact ball bearing retainer comprises a retainer main body, and is characterized in that grease storage grooves are formed on one side or on two sides of the wall of the external diameter of the retainer main body. Because the grease storage grooves are formed on one side or on two sides of the wall of the external diameter of the retainer main body and the grease storage space of a bearing is increased, the grease storage grooves on the retainer ensures that the grease storage space of the bearing is increased by 5 percent, particularly, the grease storage grooves are very near to a rolling body and a roller path, and the lubricating grease can enter a rolling region easily so as to achieve the lubricating effect effectively, that is, the lubricating grease inside the grease storage grooves are useful. Due to the adoption of the structure of the retainer, the service life of the bearing is improved by 10 percent approximately.
Description
Technical field
The utility model relates to the grease lubrication angular contact ball bearing cage, particularly relates 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 purpose of this utility model 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 the utility model grease lubrication angular contact ball bearing cage: 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 utility model, 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 utility model, 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 the utility model grease lubrication angular contact ball bearing cage schematic representation.
Embodiment
The utility model 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)
