Abstract
The utility model relates to a bearing lubrication structure which comprises a bearing, a mounting base, a rotating shaft and a liner. The rotating shaft is mounted on the mounting base through the bearing and the liner; a bearing axial positioning step is arranged on the liner; a cutting surface is arranged in the outer diameter of the step; an arc-shaped cutting surface is arranged on the cutting surface close to the bottom of liner; a through-hole is formed on the arc-shaped cutting surface; and the other end of the through-hole is opposite to the space between an inner ring and an outer ring of the bearing. The cutting surface is additionally arranged in the outer diameter of the liner and a spray hole is formed at the bottom, and the sprayed lubricant can directly lubricate the bearing. The bearing lubrication structure has simple structure and convenient technology, and can be widely applied to the lubrication of various bearings.
Description
Technical field
The utility model relates to a kind of lubricating structure, especially a kind of bearing lubrication structure.
Background technique
In the existing technology, adopt bearing to realize the running of rotating shaft mostly, and the lubricated of bearing generally is bath lubrication, promptly lubricating oil is provided with groove outward by lining, and lubricating oil flows to the outer shroud of bearing by a through hole in groove, slowly soak on the ball to be lubricated again.But this kind structure is when bearing runs up, and lubricating oil disperses easily, and stopped by high velocity air and be difficult to enter bearing, and the lubricating oil utilization ratio is low, can cause bearing lubrication bad.
Summary of the invention
The purpose of this utility model provides a kind of can realize running up the time, and bearing is carried out lubricated efficiently structure.
The technical solution of the utility model is: structure comprises bearing, fitting seat, rotating shaft, lining, rotating shaft is installed on the fitting seat by bearing, lining, described lining is provided with bearing shaft to positioning step, the external diameter of the position of step is provided with the cutting face, bottom near lining on the cutting face is provided with an arc milling face, described arc milling face is provided with through hole, and the direction of the other end of through hole is facing between the inside and outside ring of described bearing.
The utility model will be cancelled near the groove on the bearing outside diameter on the former lining, on the lining external diameter, increase the cutting face, and at bottom increase spray-hole, lubricating oil is subjected to passing through through hole behind the high pressure outside lining, is spray pattern and enters bearing, because through hole faces the inside and outside ring of bearing, therefore the lubricating oil of ejection directly is lubricated bearing, simple for structure, technology is convenient, can be widely used in various bearing lubricated.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a lining schematic representation of the present utility model.
