Abstract

The invention relates to a roller bearing equipped with a plurality of oil-storing separating elements, which comprises an inner ring, an outer ring and a plurality of rolling elements, wherein, each rolling element is shaped of a cone or cylinder and is arranged between the ball tracks of the inner ring and the outer ring; a separating element is arranged between the any two adjacent rolling elements, which has two circular arc surfaces in contact with the revolving surfaces of the adjacent rolling elements and is provided with a groove on each circular arc surface. The roller bearing provided by the invention has the beneficial effects that a layer of oil film is formed on the circular arc surface of the separating element when the roller bearing revolves and the groove on the circular arc surface is used for storing the oil, which greatly improve the lubricating condition of the rolling elements, thus adequately lengthening the service life of the roller bearing under the condition that grease oil is the only choice.

Description

The roller bearing of band oil storage spacer body

Technical field

The present invention relates to rolling bearing, relating in particular to rolling element is circular cone or columned roller bearing.

Background technique

Rolling bearing all has a guard ring that places between outer ring and the inner ring, also claims " fender bracket ".The effect of guard ring is with spaced apart between each rolling element, rolling element is contacted with each other and produces friction.At present known rolling element is in circular cone or the columned roller bearing, guard ring is that line contacts with rolling element, when bearing rotates, lubricating grease on the rolling element can be wiped off a part by guard ring and be thrown out of, the result causes roller bearing after work a period of time, the rolling element lubricating condition worsens, and bearing weares and teares too early.

Summary of the invention

The purpose of this invention is to provide a kind of roller bearing with the oil storage spacer body.

The main technical schemes that the present invention takes is: a kind of roller bearing with the oil storage spacer body, comprise inner ring, outer ring and rolling element, rolling element is a circular cone or cylindric, rolling element is clipped between the raceway of inner ring and outer ring, be provided with spacer body between per two rolling elements, described spacer body has the arc surface that contacts with the turning surface of rolling element, is provided with groove on this arc surface.

The beneficial effect that has according to roller bearing provided by the invention is: when bearing rotates, on the arc surface of spacer body, form one deck oil film, and the groove on the arc surface plays the oil storage effect, greatly improved the lubricating condition of rolling element thus, significantly prolonged the working life of bearing under the condition that can only use grease lubrication oil.

Fig. 3 is the outline drawing of the independent spacer body among Fig. 2;

Fig. 4 is the left view of Fig. 3;

Fig. 5 is the B-B revolved sectional view of Fig. 3.

Embodiment

According to the embodiment of roller bearing provided by the invention as shown in Figure 1 and Figure 2, comprise inner ring 1, outer ring 2 and rolling element 3.Rolling element 3 is clipped between the raceway of inner ring 1 and outer ring 2, is circular cone or cylindric.Be provided with spacer body 4 between per two rolling elements 3, rolling element 3 is evenly distributed.Respectively be provided with back-up

ring

5,6 at the forward and backward two ends of spacer body 4.The center line of back-up

ring

5,6 is exactly the shaft axis of bearing.All spacer bodies 4 and back-up

ring

5,6 riveted joints.Back-up

ring

5,6 plays and supports all spacer bodies 4, and makes spacer body 4 equally distributed effects.

To shown in Figure 5, spacer body 4 has the arc surface 4a that contacts with the turning surface of rolling element 3, is provided with groove 7 on this arc surface as Fig. 2.When bearing rotates, just when rolling element 3 rolls, on the arc surface 4a of spacer body 4, form one deck oil film, and the groove on the arc surface 7 plays the oil storage effect, thereby greatly improved the lubricating condition of rolling element 3.

Claims

1. roller bearing with the oil storage spacer body, comprise inner ring, outer ring and rolling element, rolling element is a circular cone or cylindric, rolling element is clipped between the raceway of inner ring and outer ring, be provided with spacer body between per two rolling elements, it is characterized in that: described spacer body has the arc surface that contacts with the turning surface of rolling element, is provided with groove on this arc surface.
