Abstract
The utility model relates to a double track way angular contact bearing, including bearing inner race, bearing inner race, steel ball, the bearing inner race suit is in bearing inner race's the outside, and bearing inner race's internal surface is global with a pair of opposition of bearing inner race's surface formation, is equipped with an arc track on bearing inner race's the internal surface, is equipped with a plurality of circular arc recesses on bearing inner race's the surface, and the steel ball block is between arc track and circular arc recess, being provided with the dust ring between bearing inner race and the bearing inner race, all being equipped with the oil storage hole on the inner wall of bearing inner race's arc track and bearing inner race's circular arc recess, the opening in oil storage hole is located the inner wall of arc track or circular arc recess, the downthehole packing of oil storage have soak there is lubricating oil lead the oil piece, lead the oil piece from the opening in oil storage hole stretch out with the surface contact of steel ball. At steel ball pivoted in -process, lead the oil piece and paint lubricating oil on the surface of steel ball, both play the cooling and also played lubricated effect.
Description
Technical field
The utility model relates to a kind of two-orbit angular contact bearing.
Background technique
Angular contact ball bearing mainly bears larger unidirectional axial load, and contact angle is larger, and it is larger to bear load carrying capacity.Can work at higher rotational speeds, wrapping angle is larger, and axial carrying capacity is higher, and highi degree of accuracy and high-speed bearing get 15 degree of wrapping angles usually.Under responsive to axial force, wrapping angle can increase, and single-row angular contact ball bearing can only bear the axial load in a direction, when bearing radial load, will cause additional axial force.And can only restrictive axes or the axial displacement of shell in a direction, if duplex is installed in pairs, make the outer ring of pair of bearings relative, namely wide end surface is to wide end surface, and narrow end surface is to narrow end surface.Can avoid like this causing additional axial force, and axle or shell can be limited within the scope of axial internal clearance in both direction.Because angular contact ball bearing mainly bears larger unidirectional axial load, can be there is steel ball and rotate discontinuous in present two-orbit angular contact bearing, rotate defaulted defect, and the heat that bearing rotation produces can not get distributing timely, cause part distortion, have impact on working life.
Model utility content
The purpose of this utility model is the defect in order to solve in prior art existing for two-orbit angular contact bearing, provides a kind of good heat dissipation and the two-orbit angular contact bearing of steel ball high lubricating effect.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of two-orbit angular contact bearing, comprise bearing outer ring, bearing inner race, steel ball, described bearing outer ring is sleeved on the outside of bearing inner race, the internal surface of bearing outer ring and the outer surface of bearing inner race form a pair opposed side face, the internal surface of described bearing outer ring is provided with an arc track, the outer surface of bearing inner race is provided with multiple arc groove, and described steel ball card is combined between arc track and arc groove; Dust ring is provided with between described bearing outer ring and bearing inner race, the inwall of the arc track of described bearing outer ring and the arc groove of bearing inner race is equipped with oil storage hole, the opening of oil storage hole is positioned on the inwall of arc track or arc groove, in oil storage hole, be filled with the oil guide piece being soaked with lubricant oil, oil guide piece stretches out the surface contact with steel ball from the opening of oil storage hole.
Above-mentioned a kind of two-orbit angular contact bearing, the short transverse of described bearing inner race inwall is provided with multiple radiating groove.
Above-mentioned a kind of two-orbit angular contact bearing, described radiating groove circumference on bearing inner race extends.
Above-mentioned a kind of two-orbit angular contact bearing, the edge of described dust ring is provided with fixed block.
The beneficial effects of the utility model are: the inwall of the arc track of this bearing and the arc groove of bearing inner race is equipped with oil storage hole, the opening of oil storage hole is positioned on the inwall of arc track or arc groove, the oil guide piece being soaked with lubricant oil is filled with in oil storage hole, oil guide piece stretches out the surface contact with steel ball from the opening of oil storage hole, in the process that steel ball rotates, lubricant oil is spread upon the surface of steel ball by oil guide piece, both the effect that cooling also serves lubrication had been served, the short transverse of bearing inner race inwall is provided with multiple radiating groove, also the effect of heat radiation is served in the process that bearing rotates.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A district enlarged view in Fig. 1.
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:
As shown in Figure 1 and Figure 2, a kind of two-orbit angular contact bearing, comprise bearing outer ring 1, bearing inner race 2, steel ball 3, bearing outer ring 1 is sleeved on the outside of bearing inner race 2, internal surface and the outer surface of bearing inner race 2 of bearing outer ring 1 form a pair opposed side face, the internal surface of bearing outer ring 1 is provided with an arc track, and the outer surface of bearing inner race 2 is provided with multiple arc groove, and steel ball 3 is fastened between arc track and arc groove, dust ring 4 is provided with between bearing outer ring 1 and bearing inner race 2, the edge of dust ring 4 is provided with fixed block 5, the inwall of the arc track of bearing outer ring 1 and the arc groove of bearing inner race 2 is equipped with oil storage hole 6, the opening of oil storage hole 6 is positioned on the inwall of arc track or arc groove, the oil guide piece 7 being soaked with lubricant oil is filled with in oil storage hole 6, oil guide piece 7 stretches out the surface contact with steel ball 3 from the opening of oil storage hole 6, in the process that steel ball rotates, lubricant oil is spread upon the surface of steel ball by oil guide piece 7, both the effect that cooling also serves lubrication had been served, further, the short transverse of bearing inner race 2 inwall is provided with multiple radiating groove 8, radiating groove 8 circumference on bearing inner race 2 extends, also the effect of heat radiation is served in the process that bearing rotates, and, in the event of high temperatures, even if bearing inner race 2 expands, under the effect of radiating groove 8, also can expand evenly, there will not be distortion, extend the working life of bearing.
