Abstract
The invention discloses a bearing inner ring which comprises a bearing inner ring body, wherein circular grooves are symmetrically formed on the front surface and the back surface of the bearing inner ring body; a plurality of heat radiation holes are formed on the bearing inner ring body at intervals; and each heat radiation hole is communicated with two circular grooves. Through the bearing inner ring provided by the invention, the weight of a bearing is reduced greatly, thus the bearing inner ring is convenient to install; and at the same time, the heat radiation effect is improved, the service life of the bearing inner ring provided by the invention is prolonged, and inconvenience brought about by frequent replacement is avoided.
Description
Technical field
The present invention relates to a kind of bearing inner race, especially a kind of bearing inner race that is used for heavy mechanical equipment.
Background technique
Bearing is in machinery, to play parts fixing and supporting axle, also has the effect that reduces the friction factor in the power transmission process.Existing bearing can be divided into two types on rolling bearing and sliding bearing; Rolling bearing is made up of inner ring, outer ring, rolling element and roller holder four parts usually; And sliding bearing is made up of inner ring, outer ring and slide mass three parts, and bearing inner race directly contacts with the surface of axle.The thinner thickness of existing bearing inner race uses and will find the phenomenon that ruptures after some times, but in some heavy mechanical equipments, because the diameter of axle is bigger, like the thickness thickening with bearing inner race, then can increase the weight of bearing inner race, is difficult for installing; In heavy mechanical equipment, the heat radiation of bearing has been satisfied not in single lubricant oil heat radiation, makes shorten the working life of bearing, has increased the inconvenience that the frequent change bearing brings in addition.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of be used for heavy mechanical equipment and be convenient to install, the bearing inner race of good heat dissipation effect.
Technical solution of the present invention is achieved in that a kind of bearing inner race, comprises the bearing inner race body, and symmetry has a circular trough on the positive and negative surface of said bearing inner race body; The first-class indirect a plurality of radiation holes that have of said bearing inner race body; Said each radiation hole all communicates with two circular troughs.
Preferably, said radiation hole is provided with 8 at least.
Preferably, indirectly in said arbitrary circular groove etc. be provided with at least two radiating fin; Said radiating fin is arranged on the bearing inner race body, and is positioned between any two radiation holes.
Preferably, indirectly in said two circular grooves etc. be provided with at least two radiating fin; Said radiating fin is arranged on the bearing inner race body, and is positioned between any two radiation holes.
Preferably, said radiating fin number is 4.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Bearing inner race of the present invention owing to the circular trough that has of symmetry on the positive and negative surface of bearing inner race body, has alleviated the weight of bearing greatly, is convenient to install; Simultaneously, because the first-class indirect a plurality of radiation holes that have of bearing inner race body, radiating effect is improved, and has increased bearing inner race of the present invention working life, the inconvenience of having avoided the frequent change bearing to bring; In addition, indirect being provided with all waits indirect at least two radiating fin that are provided with at least two radiating fin or two circular grooves in arbitrary circular groove etc., further improved radiating effect.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of bearing inner race of the present invention;
Accompanying drawing 2 is the sectional view of bearing inner race of the present invention;
Accompanying drawing 3 is the partial enlarged drawing of accompanying drawing 2;
Wherein: 1, bearing inner race body; 2, circular trough; 3, radiation hole; 4, radiating fin.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of bearing inner race shown in accompanying drawing 1-3 comprises bearing inner race body 1, and symmetry has a circular trough 2 on the positive and negative surface of said bearing inner race body 1; First-class indirect at least 8 radiation holes 3 that have of said bearing inner race body 1; Said each radiation hole 3 all communicates with two circular troughs 2; Indirect at least two radiating fin 4 that are provided with such as in said arbitrary circular groove 2; Said radiating fin 4 is arranged on the bearing inner race body 1, and is positioned at 3 of any two radiation holes; Said radiating fin number is 4.
As another embodiment of a kind of bearing inner race of the present invention, indirect at least two radiating fin 4 that are provided with such as in said two circular grooves 2; Said radiating fin 4 is arranged on the bearing inner race body 1, and is positioned at 3 of any two radiation holes; Said radiating fin 4 numbers are 4.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
