Abstract
A rolling bearing retainer for sidewall band radiating fin, is made up of the overall support body with through hole, and the both ends of the surface of support body are fixed with the upper and lower fin consistent with rolling bearing sense of rotation, and upper and lower fin favours the inside and outside circle edge of support body sidewall and installs; Uniform, raised, symmetrical, the fixing upper and lower fin identical with bearing rotary direction of inclination is added in the both ends of the surface of support body, its first and last end tilts respectively to the tangent direction of the inside and outside circle edge of support body sidewall, when retainer is with bearing High Rotation Speed, by the centripetal force that air radial thrust produces, can offset the part centrifugal power that retainer produces when working and rotating, what decrease retainer is stressedly conducive to improving retainer working life.Add heat diffusion area, reduce rolling bearing operating temperature, good cooling results, improve rolling bearing running speed, working efficiency, reduce and the stuck fault of the various heating of bearing occurs, do not need other power or the energy, use safety, reliable, structure simply, easily makes enforcement.
Description
Technical field
The utility model relates to a kind of retainer of rolling bearing, particularly a kind of rolling bearing retainer of sidewall band radiating fin with heat sinking function, good cooling results.
Background technique
Because the mounting point of rolling bearing retainer is narrow, the bearing heat produced that operates for a long time is difficult to be dispersed in air and goes, if heat can not distribute timely and effectively, will occur to cause because bearing operating temperatures is too high bearing to burn out stuck fault, greatly reduce the working life of bearing.
Patent No. ZL200920232578.4 " disk bearing retainer ", just provides a kind of retainer of new structure, utilizes and offer first, second oilhole on the lintel of retainer and the outer ring of lintel, for improving lubrication and the heat dispersion of raceway.
Patent No. ZL200820088904.4 " external bracing type cylindrical roller bearing holder ", ZL200820088905.9 " inner pulling type cylindrical roller bearing cage ", the inclined-plane of symmetrical inclination is provided with in the two edges of retainer, though be all overall structure, but its retainer volume is large, heavy weight, mainly uses on air condition compressor.
Summary of the invention
Technical problem to be solved in the utility model is: the rolling bearing retainer providing a kind of sidewall band radiating fin, this retainer effectively can reduce running temperature, the good cooling results of rolling bearing, improve bearing operation speed and working efficiency again, also reduce various heating accident and increase the service life.
The technical scheme in the invention for solving the above technical problem is: the rolling bearing retainer of sidewall band radiating fin, be made up of the overall support body with through hole, the both ends of the surface of described support body are fixed with the upper and lower fin consistent with rolling bearing sense of rotation, and described upper and lower fin favours the inside and outside circle edge of support body sidewall and installs;
Height h, length L, the width B of described upper and lower fin are identical, are symmetrical, uniform, raised long strip, and the inside and outside surface of described upper and lower fin is plane;
The exterior edge face of described upper and lower fin there is continuous, identical sawtooth;
The first and last end of described upper and lower fin tilts respectively to the tangent direction of the inside and outside circle edge of support body sidewall.
Compared with prior art, the utility model has the advantage of: the rolling bearing retainer of sidewall band radiating fin, add uniform in the both ends of the surface of support body, raised, symmetrical, tilt fixing identical with bearing rotary direction upper, lower fin, and on, the first and last end of lower fin is respectively in support body sidewall, the tangent direction of outer annulus edge tilts, when it is with bearing High Rotation Speed, the centripetal force that the radial thrust being subject to air produces, the part centrifugal power that retainer produces when working and rotating can be offset, additionally reduce the stressed of retainer like this, thus be conducive to the working life of improving retainer.Upper and lower fin plays again fan blade and can stir, instigate air in addition, increase and the contact of air and heat exchange area, strengthen and promote the convection current of air and circulation is carried out conducting heat, dispelling the heat, the heat produced when being operated by rolling bearing is taken away in time and effectively distributes, the operating temperature of rolling bearing can be reduced, thus improve running speed and the working efficiency of rolling bearing, reduce and the stuck fault of the various heating of bearing occurs, substantially prolongs the working life of bearing.Upper and lower fin, with retainer high speed rotating, does not need other power or the energy, use safety, reliable, and structure simply, easily makes.The exterior edge face of simultaneously upper and lower fin also has continuous print sawtooth, increases again, expand heat diffusion area and can take away more heat, cooling effect is obvious.
Accompanying drawing explanation

The plan view of Fig. 2, Fig. 1.
The structural representation of Fig. 3, upper fin.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Rolling element in rolling bearing can be steel ball or cylindrical roller, and the through hole 2 on retainer support body 1 is for placing rolling element.
According to self-contained bearing needs, have fixing uniform, raised, symmetrical also consistent with bearing rotary direction in the upper/lower terminal face of support body 1, and the upper fin 3, the lower fin 4 that tilt.
The first and end of upper and lower fin 3,4 tilts with the tangent direction of the inside and outside circle edge of support body 1 sidewall respectively, ensures that the heat diffusion area of upper and lower fin is maximum.
True dip direction, the sense of rotation of upper and lower fin 3,4 are identical, when bearing High Rotation Speed, the air thrust that upper and lower fin is subject to is radial centripetal force, the part centrifugal power produced when can also offset retainer work, is conducive to the working life of improving retainer.
Height h, length L, the width B of upper and lower fin 3,4 are identical, be symmetrical, uniform, raised long strip, and the inside and outside surface of long strip are plane, easily makes processing, and height h is the seal ring or the dust cover that do not touch rolling bearing.
The exterior edge face of upper and lower fin 3,4 there is consecutive identical sawtooth 5, turn increases ventilation, heat diffusion area.
The support body of this retainer can use the various different materials such as low carbon steel, stainless steel, bakelite, plastics, brass, bronze, aluminum alloy to make.
During use, the retainer made is arranged on (figure does not draw) in the inside and outside circle of bearing, and make the exterior edge face of upper and lower fin can not touch seal ring or the dust cover of rolling bearing, on retainer support body, the true dip direction of upper and lower fin is consistent with the sense of rotation of bearing, bearing is high speed rotating under shaft torque drives, by the continuous agitation air of upper and lower fin, strengthen convection current and the circulation of air, add heat diffusion area, the heat produced at work by bearing distributes in time more, enhances cooling effect, and successful.
This retainer be not only applicable to open, without the rolling bearing of seal ring, dust cover, be also applicable to the incomplete half-sealed rolling bearing use of sealing simultaneously.
