Abstract
The utility model relates to a kind of deep-groove ball retainers with oil storage slot structure, including deep-groove ball retainer ontology, the ball pocket for placing steel ball is offered on deep-groove ball retainer ontology, the outer wall and inner wall of the deep-groove ball retainer ontology offer the oil storage tank of equal part respectively, the linkage section between adjacent two balls pocket is arranged in the oil storage tank, and the oil storage tank of outer wall and the oil storage tank of inner wall correspond, the outer wall or inner wall of linkage section are run through in each oil storage tank top and bottom end.Steel ball is directly contacted with the inside and outside circle raceway without grease of bearing during the deep-groove ball retainer with oil storage slot structure can prevent bearing from running at high speed, bearing operation temperature is caused to increase the initial failure with bearing, temperature rise and noise during raising bearing operation service life and reduction bearing rotary.
Description
Technical field
The utility model relates to technical field of bearings more particularly to a kind of deep-groove ball retainers with oil storage slot structure.
Background technique
During running at high speed, steel ball often goes out existing deep-groove ball retainer with bearing inner race, outer ring raceway
The phenomenon that existing insufficient lubrication, cause noise in operational process excessive, bearing operation temperature increases and leads to bearing failure.Although existing
There are some bearing retainers to start using oil storage groove mechanism, in one kind as disclosed in Patent No. CN201547135U,
Outer diameter has the bearing retainer of oil storage tank, however such retainer structure is complex, and the structure of oil storage tank needs the later period two
Secondary machine-shaping, processing technology is complex, very inconvenient.
Utility model content
Simple, high lubricating effect that the purpose of the utility model is to provide a kind of structures easy to process has oil storage tank knot
The deep-groove ball retainer of structure.
The utility model is achieved by the following technical solution: a kind of deep-groove ball retainer with oil storage slot structure,
Including deep-groove ball retainer ontology, the ball pocket for placing steel ball, the deep-groove ball retainer are offered on deep-groove ball retainer ontology
The outer wall and inner wall of ontology offer the oil storage tank of equal part respectively, and the connection between adjacent two balls pocket is arranged in the oil storage tank
The outer wall of linkage section is run through in section, and the oil storage tank of the oil storage tank of outer wall and inner wall one-to-one correspondence, each oil storage tank top and bottom end
Or inner wall.
In one preferred embodiment of the utility model, the oil storage tank is preferably rectangle, the top end opening width of oil storage tank
It is of same size with bottom opening.Certainly, the similar structures such as arc-shaped, trapezoidal shape can also be used in oil storage tank.
In order to guarantee antiwhip, avoid oil storage tank notch excessive and cause to occur in bearing operational process shake and
Retainer structural strength is reduced, preferably, the top end opening width or bottom opening width of the oil storage tank are connection segment length
Within the half of degree, the depth of the oil storage tank is within a quarter of deep-groove ball retainer body thickness.
The beneficial effects of the utility model are: the deep-groove ball retainer that should have oil storage slot structure passes through the special of setting
Oil storage slot structure can store certain grease to Bearing inner greasing, oil storage tank by oil storage tank, run at high speed in bearing
In the process, what the grease in oil storage tank can continue provides certain grease to raceway and steel ball surface, prevents bearing from running at high speed
Steel ball is directly contacted with the inside and outside circle raceway without grease of bearing in the process, is caused bearing operation temperature to increase and is lost with the early stage of bearing
Effect, if bearing lubrication is cooled down by external lubricating oil, oil storage tank can provide the path that lubricating oil enters bearing, keep
Bearing inner (steel ball, inner ring, outer ring) lubrication sufficiently, improve the bearing operation service life and reduce bearing rotary during temperature rise with
Noise.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the deep-groove ball retainer with oil storage slot structure of the utility model；
Fig. 2 is the main view of the deep-groove ball retainer with oil storage slot structure of the utility model；
In figure: 1. deep-groove ball retainer ontologies, 2. ball pockets, 3. oil storage tanks, 4. linkage sections.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be understood by those skilled in the art with feature, to make apparent specific boundary to the protection scope of the utility model
It is fixed.Direction term that the utility model is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom" etc.,
It is only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the utility model, rather than to
Limit the utility model.
As shown in Figure 1 and Figure 2, a kind of deep-groove ball retainer with oil storage slot structure, including deep-groove ball retainer ontology 1,
The ball pocket 2 for placing steel ball, the outer wall and inner wall point of the deep-groove ball retainer ontology 1 are offered on deep-groove ball retainer ontology 1
The oil storage tank 3 of equal part is not offered, and the linkage section 4 between adjacent two balls pocket 2, and the oil storage of outer wall is arranged in the oil storage tank 3
The outer wall or inner wall of linkage section 4 are run through in the oil storage tank 3 of slot 3 and inner wall one-to-one correspondence, each 3 top of oil storage tank and bottom end.
The oil storage tank 3 is rectangle, and the top end opening width and bottom opening of oil storage tank 3 are of same size, and oil storage tank 3
Top end opening width or bottom opening width are less than the half of 4 length of linkage section, and the depth of oil storage tank 3 is protected less than deep-groove ball
Hold a quarter of 1 thickness of frame ontology.
Oil storage tank 3 in the deep-groove ball retainer with oil storage slot structure can be processed and formed at one time with ontology, very
It is convenient.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.
