Abstract
A bearing cage provided with oil storage grooves at inner diameter and outer diameter is formed by manufacturing a cage outer diameter semicircular oil groove (2) penetrating through a connection lintel (1) in the middle portion of an outer diameter of the lintel of each cylindrical pocket of an original bearing cage, and manufacturing a cage inner diameter semicircular oil groove (3) penetrating through a lintel in the middle portion of an inner diameter of the connection lintel between each cylindrical pocket and the adjacent cylindrical pocket of the original cage. The cage outer diameter semicircular oil grooves and the cage inner diameter semicircular oil grooves are capable of storing small amount of lubricating oil, thereby resolving the problem of self oil storage of the bearing cage, avoiding temporary oil deficiency occurring in use, reducing damages such as bearing burn and the like due to the oil deficiency in use, and prolonging lubricating and main unit maintenance period.
Description
Technical field
The utility model belongs to technical field of bearings, and especially a kind of inside and outside footpath has the retainer of oil storage tank.
Background technique
The retainer of existing Biserial cylindrical roller bearing and four-line column roller bearing is a cirque body comb type overall structure, retainer dress roller pocket hole is the straight pocket of cylinder type hole, the pocket hole is staggered in the whole both ends of the surface of cirque body comb type, and connecting between pocket hole and the pocket hole is called the retainer lintel.Because this retainer self do not design oil storage tank, therefore under oil starvation or weary oily situation, be easy to take place the sintering of rolling element and bearing ring raceway between the pocket hole, cause the unusual damage of bearing.
Summary of the invention
For addressing the above problem, the utility model has designed the retainer that a kind of inside and outside footpath has oil storage tank, can contain minor amounts of lubricants in retainer external diameter semi-circle oil groove and the retainer internal diameter semi-circle oil groove, so just solved the problem of retainer self oil storage, the weary oily phenomenon that has occurred in short-term in having avoided using.
For achieving the above object, the utility model adopts following technological scheme:
The retainer that described inside and outside footpath has oil storage tank is that the external diameter middle part that connects lintel in each cylinder pocket hole of former retainer is processed with the retainer external diameter semi-circle oil groove that runs through lintel, and is processed with the retainer internal diameter semi-circle oil groove that runs through lintel in the middle part of the internal diameter that connects lintel between each cylinder pocket hole of former retainer and the adjacent column pocket hole.
Because adopt aforesaid technological scheme, the utility model produces following good effect:
1, the utility model does not change the basic structure of Biserial cylindrical roller bearing and four-line column roller bearing retainer, just the external diameter middle part that connects lintel in each cylinder pocket hole of former retainer be processed with the retainer external diameter semi-circle oil groove that runs through lintel and between each cylinder pocket hole of former retainer and adjacent column pocket hole connect the lintel internal diameter in the middle part of be processed with the retainer internal diameter semi-circle oil groove that runs through lintel, so just solved the problem of retainer self oil storage, the weary oily phenomenon that has occurred in short-term in having avoided using, reduce the harm such as burn bearing that cause owing to oil starvation in using, prolonged the host maintenance cycle.
2, to process inside and outside footpath semi-circle oil groove method easy for the utility model, is easy to realize, also may extend to other similar retainer.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Among the above-mentioned figure: the 1-lintel; 2-retainer external diameter semi-circle oil groove; 3-retainer internal diameter semi-circle oil groove.
Embodiment
In conjunction with Fig. 1-2, the retainer that inside and outside footpath of the present utility model has oil storage tank is that the external diameter middle part that connects lintel 1 in each cylinder pocket hole of former retainer is processed with the retainer external diameter semi-circle oil groove 2 that runs through lintel, and is processed with the retainer internal diameter semi-circle oil groove 3 that runs through lintel in the middle part of the internal diameter that connects lintel 1 between each cylinder pocket hole of former retainer and the adjacent column pocket hole.
Need to prove: the utility model does not change the basic structure of Biserial cylindrical roller bearing and four-line column roller bearing retainer, just the external diameter middle part that connects lintel in each cylinder pocket hole of former retainer be processed with the retainer external diameter semi-circle oil groove that runs through lintel and between each cylinder pocket hole of former retainer and adjacent column pocket hole connect the lintel internal diameter in the middle part of be processed with the retainer internal diameter semi-circle oil groove that runs through lintel, can contain minor amounts of lubricants in retainer external diameter semi-circle oil groove and the retainer internal diameter semi-circle oil groove, so just solved the problem of retainer self oil storage, the weary oily phenomenon that has occurred in short-term in having avoided using, the harm such as burn bearing that cause owing to oil starvation in using have been reduced, to prolong lubricated and host maintenance cycle.
Claims (1)
1. an inside and outside footpath has the retainer of oil storage tank, it is characterized in that: the external diameter middle part that connects lintel (1) in each cylinder pocket hole of former retainer is processed with the retainer external diameter semi-circle oil groove (2) that runs through lintel, and is processed with the retainer internal diameter semi-circle oil groove (3) that runs through lintel in the middle part of the internal diameter that connects lintel (1) between each cylinder pocket hole of former retainer and the adjacent column pocket hole.
