Abstract
The invention discloses a novel double-row tapered bearing based on outer-ring lubrication grooves. The novel double-row tapered bearing comprises two outer rings 5 spaced by a middle outer ring spacer 1, and an inner ring 8 sleeved concentrically in the inner part. Two tapered rollers 6 are respectively disposed between the inner ring 8 and one of the outer rings as well as between the inner ring 8 and the other outer ring through cages 7. The novel double-row tapered bearing is characterized in that the end sides contacting the outer ring spacer 1 of the outer rings are respectively provided with an oil groove 3, and the oil grooves lead to the tapered rollers and the cages 7. According to the novel double-row tapered bearing, previous oil holes in outer ring spacers are changed to be in the big-mouth cross sections of the outer rings, and therefore the ring spacer can bear large load and is not liable to break. The oil grooves are milled in the large-mouth end faces of the outer rings in consideration of small stress on the big-mouth end faces of the novel double-row tapered bearing, and therefore lubricating oil can flow into a roller path through the outer-ring oil holes so as to allow sufficient lubrication of the bearing during working and the service lifetime of the bearing is prolonged.
Description
Technical field
The present invention relates to technical field of bearings.
Background technique
As shown in Figure 1, the structure of prior art biserial conical bearing comprises the both sides outer ring 5 placed separately by middle outer ring spacer 1, and the inner ring 8 of inner concentric socket, between described inner ring 8 and outer ring, both sides 5, is provided with tapered roller 6 respectively by retainer 7.
Wherein, the middle part of outer ring spacer 1 is provided with the oilhole 2 that leads to roller and retainer.Problem is, lubrication hole is far away apart from roller, and lubrication effect is poor.
Summary of the invention
The present invention aims to provide a kind of biserial conical bearing of high lubricating effect.
In order to achieve the above object, the invention provides a kind of Novel double-row conical bearing based on outer ring lubrication groove, comprise the both sides outer ring placed separately by middle outer ring spacer, and the inner ring of inner concentric socket, between described inner ring and outer ring, both sides, be provided with tapered roller by retainer respectively.The distolateral oil groove that offers respectively that the described outer ring of both sides contacts with described outer ring spacer, described oil groove leads to described tapered roller and described retainer place.
Novel tapered roller bearing of the present invention is that the oilhole in outer ring spacer is in the past changed on the section of large mouthful of outer ring.Make like this spacer ring can bear larger load, and be not easy cracked.As novel tapered roller bearing, consider that its big opening end face is stressed little, therefore at its outer ring big opening end facing cut oil groove.Can fully make like this lubricant oil flow to and obtain fully lubrication while making bearing operation in raceway by outer ring oilhole.Thereby improve the working life of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art biserial conical bearing.
Fig. 2 is the structural representation of biserial conical bearing of the present invention.
Embodiment
The present invention is based on as shown in Figure 2 the Novel double-row conical bearing of outer ring lubrication groove, comprise the both sides outer ring 5 placed separately by middle outer ring spacer 1, and the inner ring 8 of inner concentric socket, between described inner ring 8 and outer ring, both sides 5, be provided with tapered roller 6 by retainer 7 respectively; It is characterized in that, the distolateral oil groove 3 that offers respectively that the described outer ring 5 of both sides contacts with described outer ring spacer 1, described oil groove 3 leads to described tapered roller and described retainer 7 places.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technological scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
