Abstract

The utility model discloses an angle contact ball bearing outer ring with an oil injection structure. The outer ring is provided with an oil injection groove (1) and a bearing channel (3); the oil injection groove (1) is provided with an oil injection hole (2) leading to a bearing rolling body (5); the oil injection hole (2) is positioned in the bearing channel (3); and the outer ring adopting the structure leads the bearing to be capable of effectively injecting clean lubricating oil into the bearing channel (3) so as to lubricate all surfaces for rolling of a bearing and avoid the invalidation of the bearing due to poor lubrication.

Description

The angular contact ball bearing outer ring that has oil injection structure

Technical field

The utility model relates to a kind of outer ring of bearing, particularly a kind of angular contact ball bearing outer ring that has oil injection structure.

Background technique

In some application, the Environmental Conditions of bearing is very severe comparatively speaking, bearing directly contacts with dust, mud, water etc., use condition from present bearing, reasons such as the immersion of foreign matter make bearing can not get good lubricating, and cause bearing corrosion, wearing and tearing to account for a very big part.In addition, using in the machinery of angular contact ball bearing, needing regularly or for a long time to bearing filling lubricant oil in part, traditional method is owing to the reason of bearing structure, be difficult to directly effectively annotate on the bearing element surface, bearing can not get good lubricating, thus too early damage.

The model utility content

Problem to be solved in the utility model provides a kind of angular contact ball bearing outer ring that has oil injection structure, under the prerequisite that does not influence bearing load carrying capacity, by designing a kind of angular contact ball bearing outer ring structure that has oil hole and oiling groove, can be directly when making bearing in use annotate lubricant oil, effectively with oil filling in bearing channel, and turbidity test are effectively guaranteed.

For reaching above-mentioned technical purpose, the technical solution of the utility model is: a kind of angular contact ball bearing outer ring that has oil injection structure,: described outer ring is provided with oiling groove and bearing channel, and oiling groove is provided with the oil hole that leads to bearing roller, and oil hole is positioned at bearing channel.

Consider that from the bearing capacity of bearing the oil hole setting should be avoided the contact area of rolling element in the bearing.

Lubricant oil enters in the oiling groove of bearing outer ring by the oil hole of machinery upper bearing (metal) housing, and the oil hole of flowing through then enters bearing channel inside again, realizes that the directly effective filling of lubricant oil is on the bearing element surface.

Adopt the outer ring of said structure, make bearing in use, can be directly effectively with the oil filling of cleaning in bearing channel, each surface that lubricating bearings rolls has avoided bearing owing to insufficient lubrication lost efficacy.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an A portion enlarged view among Fig. 1.

Embodiment

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an A bilge construction schematic representation among Fig. 1, as shown in Figure 2, the utility model design has oiling groove 1, bearing channel 3, the angular contact ball bearing outer ring structure of oil hole 2, oil hole 2 is consistent with oiling groove 1 center, oil hole 2 is positioned at bearing channel 3 simultaneously, but avoids the contact area 5 of rotor 4 in the bearing, so to the bearing capacity did not influence of bearing.

Lubricant oil enters in the oiling groove 1 of bearing outer ring by the oil hole of machinery upper bearing (metal) housing in the use, the oil hole 2 of flowing through then, enter bearing channel 3 inside again, can be directly effectively with the oil filling of cleaning in bearing channel 3, each surface that lubricating bearings rolls, realize that the directly effective filling of lubricant oil on the bearing element surface, makes bearing obtain good lubricating, avoided bearing because of insufficient lubrication premature failure, damage.

The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.

Claims (1)

1. angular contact ball bearing outer ring that has oil injection structure, it is characterized in that: described outer ring is provided with oiling groove (1) and bearing channel (3), oiling groove (1) is provided with the oil hole (2) that leads to bearing roller (4), and the contact area (5) that oil hole (2) is avoided rolling element in the bearing (4) is positioned at bearing channel (3).
