Abstract
The utility model discloses a retainer of a roller bearing replacing an inner and an outer rings, the retainer comprises a first ring-shaped end frame (1) and a second ring-shaped end frame (2) which are separated along the axis axially, and a plurality of transverse septa (4) linking the two ring-shaped end frames (1, 2). The transverse septa (4) distribute along the circle at equal intervals, the outside surface of the transverse septa (4) is in the same level with the outside diameter surface of the two ring-shaped end frames (1, 2), the axis of the transverse septa (4) is vertical to the inside surface of the two ring-shaped end frames (1, 2), the inside between every two transverse septa (4) can be provided with a roller moveably. The radial widths of the two ring-shaped end frames (1, 2) are smaller than the roller diameter needed to be put in, the longitudinal distance between inside surfaces of the two ring-shaped end frames (1, 2) is bigger than the longitudinal length of the roller needed to be put in. The retainer can prevent the roller from squeezing and wearing in the assembly process, the structure and the processing technology thereof are simple, and the requirements on the material and the machining precision thereof are lower, the labour is saved, the time and the material are also saved.
Description
Technical field
The utility model relates to the rolling bearing that a kind of mechanical transmission is used, and specifically is the retainer that a kind of roller bearing that is used for only being made of retainer and roller replaces the roller bearing of Internal and external cycle.
Background technique
The structure of the roller holder that the no inside and outside circle of prior art promptly only is made of retainer and roller is as follows, it comprises along the axially spaced first annular end frame of axis and the second annular end frame and some tabulas of being connected these two annular end frames, described some tabulas equidistantly distribute along circumference, movablely between per two tabulas be embedded with a roller, promptly per two tabulas constitute limit simultaneously roller radially inwardly and the device of radially outward position.The roller bearing that is made of inner ring, outer ring, retainer and plurality of rollers of the bearing that is made of this retainer and roller and prior art is compared, and has the strong advantage of radially bearing capacity simple in structure, that save material, bearing.But prior art also have following shortcoming with holder: 1, because roller is activity is inlaid in the groove that two tabulas form, roller needs just can be pressed into external force, its assembling is effort, particularly adopt its bearing assembly process of this retainer inevitably roller to be produced to squeeze and hinder and wearing and tearing, directly influenced the working life of this roller bearing.2, because the radially inside and radially outer position that tabula will limit roller simultaneously, objectively require tabula itself to have complicated structure, its processing technology complexity, its material and machining accuracy all require very high, so its manufacturing is taken a lot of work, time-consuming, expense material, manufacture cost is also high relatively.
The model utility content
The technical problems to be solved in the utility model is, overcome the shortcoming of above prior art, provide a kind of can avoid assembly process to roller produce to squeeze hinder all relative low, the saving of labor of, its material all simple with processing technology, save time with requirement on machining accuracy with wearing and tearing and its structure, material-saving, the retainer of the roller bearing of the replacement Internal and external cycle that manufacture cost is low relatively.
The technical solution of the utility model is, a kind of retainer of roller bearing of the replacement Internal and external cycle with following structure is provided, it comprises along the axially spaced first annular end frame of axis and the second annular end frame and some tabulas of being connected these two annular end frames, described some tabulas equidistantly distribute along circumference, the outer surface of described tabula is concordant with the external diameter surface of two annular end frames, the axis of described tabula is vertical with the inner surface of two annular end frames, roller of movable placement between per two tabula inboards, the axial length of the roller that the diameter dimension of the roller that the radial width size of described two annular end frames is all put into less than need, described two the annular end frame inner surfaces distance between is axially put into greater than need.
After adopting above structure, the utility model replaces the retainer of the roller bearing of Internal and external cycle, compares with above-described prior art, has the following advantages:
1, can put into very easily from the inboard of retainer owing to roller, do not need to be pressed into external force, make the assembling of bearing become easier, particularly the assembly process of its bearing has been avoided crowded wound and the wearing and tearing to the roller generation fully, has prolonged the working life of the roller bearing that adopts this retainer significantly.
2, because the tabula radially outer position that only need limit roller, this body structure of tabula is very simple, and its processing technology is also very simple, and its material is all relative with requirement on machining accuracy low, thus the saving of labor, save time, material-saving, its manufacture cost is also low relatively.
Roller of movable placement between described per two tabula inboards can adopt following concrete structure: the diameter of the roller that the distance between per two tabula inboards is put into less than need.
As improvement, the outer surface of described each tabula can have a radial groove, and described radial groove connects the whole width of tabula, can be beneficial to lubricated and heat radiation for the lubricant oil infiltration.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2.
The utility model replaces the retainer of the roller bearing of Internal and external cycle, and it comprises along the axially spaced first annular end frame 1 of axis and the second annular end frame 2 and some tabulas 4 of being connected these two annular end frames 1,2.Described some tabulas 4 equidistantly distribute along circumference, and the outer surface of described tabula 4 is concordant with the external diameter surface of two annular end frames 1,2, and the axis of described tabula 4 is vertical with the inner surface of two annular end frames 1,2, and is also vertical with its outer surface certainly.Roller 5 of movable placement between per two tabula 4 inboards: the diameter of the roller 5 that the distance between per two tabula 4 inboards is put into less than need.The axial length of the roller 5 that the diameter dimension of the roller 5 that the radial width size of described two annular end frames 1,2 is all put into less than need, described two annular end frames, 1, the 2 inner surfaces distance between is axially put into greater than need.
The outer surface of described each tabula 4 has a radial groove 3, and described radial groove 3 connects the whole width of tabula 4.
In actual applications, in the roller bearing center hole that constitutes by this retainer and roller, can there be a restriction roller 5 radially inwardly to break away from tabula 4 and when roller bearing is loaded on the axle, can be ejected and the elasticity stop collar in hole, off center by this.
The utility model not only is confined to above embodiment; all various variations of being done in the independent claims protection domain are all in protection domain of the present utility model; as: can establish two or more circumferential projection in the both sides of tabula; roller of movable placement between described per two tabula inboards; the diameter that also can adopt roller is greater than the distance between the circumferential projection of two tabulas; if after the circumferential projection, also can not establish radial groove etc.More than these variations, all fall in the protection domain of the present utility model.
