Abstract
The utility model relates to a bearing. The bearing comprises a bearing outer ring and a bearing inner ring, wherein a rotatable steel ball is arranged between the bearing outer ring and the bearing inner ring; the bearing inner ring is provided with a shaft hole; the upper end of the shaft hole is provided with a plurality of oil holes; and an oil duct formed by the oil holes is communicated with the inner wall of the shaft hole and the outer side wall of the bearing inner ring. The bearing has the advantages that: a shaft is inserted into the shaft hole, and oil is filled into the oil holes and flows into the inner wall of the shaft hole and a position at which the steel ball is positioned through the oil duct, so that good lubricating effect is achieved and the running noise of the bearing is low.
Description
Technical field
The utility model relates to a kind of bearing.
Background technique
Existing bearing generally comprises bearing outer ring and the bearing inner race that is positioned at bearing outer ring, is provided with rotating steel ball between bearing outer ring and the bearing inner race, after service time was long, steel ball gets rusty not to be changeed easily, and axle inserts in the axis hole, because long-time running causes bearing noise big, wearing and tearing are big.
The model utility content
The technical problems to be solved in the utility model provides the bearing of a kind of high lubricating effect, steel ball long service life.
The technical scheme in the invention for solving the above technical problem is:
Bearing, comprise bearing outer ring and bearing inner race, be provided with rotating steel ball between described bearing outer ring and the bearing inner race, have axis hole in the described bearing inner race, the upper end of described axis hole has a plurality of oilholes, and the oil duct that described oilhole forms communicates with shaft hole inner wall and the outer side wall of bearing inner race communicates.
The radius of described oilhole equates with the radius of oil duct.
Advantage of the present utility model: axle is inserted axis hole, add oil in the oilhole, oily position by oil duct inflow shaft hole inner wall and steel ball place, high lubricating effect, the bearing operation noise is low.
