Abstract
The utility model relates to a take bearing of intercommunicating pore, including bearing inner race, bearing inner race, a plurality of steel ball and holder, all have the guiding gutter that circumference is extended on two sides of bearing inner race and bearing inner race, to connect through the intercommunicating pore between two last corresponding guiding gutters of bearing inner race and bearing inner race, the both ends opening of this intercommunicating pore all is located the guiding gutter, and the vestibule of intercommunicating pore is arc, and the changeover portion is connected to the vestibule and the open -ended of intercommunicating pore is the arc, and the vestibule bore of intercommunicating pore is greater than the both ends opening bore of intercommunicating pore. This bearing flows in the guiding gutter of bearing inner race and bearing inner race both sides face at pivoted in -process air, and the interior air that flows of guiding gutter that is parallel to each other on bearing inner race and the bearing inner race passes through the intercommunicating pore and forms the convection current, has further accelerated the flow of air, has strengthened radiating effect for heat on bearing inner race and the bearing inner race by interior outside to whole having gived off go out, prolonged the life of bearing.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of bearing with intercommunicating pore.
Background technique
Bearing rises fixing in mechanical transmission course and reduces the parts of load friction factor, alternatively, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.And when being installed on the positions such as main frame when bearing, the heat in the heat that bearing rotary produces and bearing support can cause the fever expansion such as bearing outer ring, bearing inner race and steel ball in bearing, and simultaneously bearing support itself also can due to fever expansion.But because the material of bearing and bearing support is different, relative expansion coefficient is also different, after temperature raises, bearing inner race and bearing support all can radially expand.Present bearing when mounted, if because bearing outer ring and bearing inner race are because temperature raises the uneven deformation of as easy as rolling off a log generation, and then affects stability and the working life of bearing operation.
Model utility content
The purpose of this utility model is the defect in order to solve existing for prior art middle (center) bearing, provides a kind of bearing with intercommunicating pore.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of bearing with intercommunicating pore, comprise bearing outer ring, bearing inner race, multiple steel ball and retainer, described bearing outer ring is sleeved on the outside of bearing inner race, and bearing outer ring is provided with the opposed side face of bearing inner race the guide-track groove settling described steel ball, and described retainer is sleeved on steel ball;
Described bearing also comprises dust cover, the both sides of described guide-track groove are provided with draw-in groove, described dust cover is fastened in this draw-in groove, all with the guiding gutter that circumference extends on two sides of described bearing outer ring and bearing inner race, bearing outer ring and bearing inner race are connected by intercommunicating pore between two corresponding guiding gutters, the both ends open of this intercommunicating pore is all positioned at described guiding gutter, the vestibule of intercommunicating pore is circular arc, the vestibule of intercommunicating pore and the connection changeover portion of opening are arc, and the vestibule bore of intercommunicating pore is greater than the both ends open bore of intercommunicating pore.
Above-mentioned a kind of bearing with intercommunicating pore, the intercommunicating pore on described bearing outer ring and bearing inner race is equidistantly arranged between the guiding gutter of two correspondences.
Above-mentioned a kind of bearing with intercommunicating pore, described dust cover circumferentially.
Above-mentioned a kind of bearing with intercommunicating pore, the edge conjunction place of described dust cover and draw-in groove is with fixed block.
The beneficial effects of the utility model: this bearing air in the process of rotating flows in the guiding gutter of bearing outer ring and bearing inner race bi-side, and guiding gutter circumference on the side of bearing outer ring and bearing inner race extends, extraneous cool air can flow in guiding gutter inner circumferential, with the heat that bearing running produces, in order to the radiating effect reached further, connected by intercommunicating pore between guiding gutter corresponding between two on bearing outer ring and bearing inner race, the both ends open of this intercommunicating pore is all positioned at guiding gutter, the vestibule of intercommunicating pore is circular arc, the vestibule of intercommunicating pore and the connection changeover portion of opening are arc, in the guiding gutter that bearing inner race and bearing outer ring are parallel to each other, the air of flowing forms convection current by intercommunicating pore, and the vestibule bore of intercommunicating pore is greater than the both ends open bore of intercommunicating pore, the air entered in intercommunicating pore forms siphon, accelerate the flowing of air further, increase the effect of heat radiation, heat on bearing inner race and bearing outer ring is all distributed from inside to outside go out, extend the working life of bearing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Further understand for making to have structure characteristic of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
