Abstract
The utility model discloses a bearing which comprises a bearing inner ring, a bearing outer ring and a ball arranged between the bearing inner ring and the bearing outer ring. The bearing is characterized in that an oil film layer with lubrication effect is coated on surfaces of the bearing inner ring, the bearing outer ring and the ball; generally the thickness of the oil film layer is 3 to 5 micrometers; and by taking bearing oil as the raw material, the oil film layer is made by adopting titanium nitride (TIN) physical vapor deposition (PVD) surface coating technology. The bearing oil takes refined mineral oil as base oil, a plurality of anti-oxygen, rust preventing and abrasion proof additives are added, and the bearing oil is mainly applied to spindles and oil film bearings. The bearing has skillful design, reduces friction coefficient among all components of the bearing and friction loss among all components connected with the bearing, and improves the rust resistance.
Description
Technical field
The utility model relates to a kind of bearing with lubrication.
Background technique
Bearing is the supporting member in the mechanical transmission mechanism, is used for determining running shaft and other part relative movement position, and its quality directly influences the service behaviour of mechanical complete machine, drives the motion of associated mechanisms by the running of bearing.Bearing bears complicated applied forces such as pressure, shearing and tired impact friction in the course of the work, when particularly producing friction in the mechanism that links to each other with bearing, consumed power not only, but also can produce certain loss to each parts of friction mutually, bearing is caused damage.
The model utility content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of bearing, and the surface is by lubricated, effectively reduces the frictional loss with connected components, helps mechanical transmission mechanism and turns round more efficiently.
To achieve these goals, the technical solution of the utility model is as follows:
Bearing, comprise bearing inner race, bearing outer ring and be arranged on ball between described bearing inner race and the bearing outer ring, be characterized in, the surface of described bearing inner race, ball and bearing outer ring evenly is coated with oil lamella, described oil lamella is to be that raw material adopts titanium nitride (TIN) physical vapor deposition (PVD) surface coating technology to make with the bearing oil, has the effect of lubricated component of machine.
Further, the thickness of described oil lamella is generally 3-5um;
Above-mentioned bearing oil is that to adopt oil petroleum refined by naphthenic be base oil, adds an amount of antioxygen, multiple additives modulation such as antirust, wear-resistant forms, and mainly is applicable to spindle and filmatic bearing, and kinematical viscosity is 6.12-7.48mm in the time of 40 ℃
2/ s, flash-point are not less than 115 ℃, and condensation point is not higher than-18 ℃.
By adopting above-mentioned oil lamella to reduce friction factor between they itself, also reduced the frictional loss between the coupled parts, and improved the rustless property of bearing.
The beneficial effects of the utility model are, this oil lamella is applicable to various bearing part, and lubrication effect was more remarkable after plated film got on, and had reduced the frictional loss between the component, had effectively prolonged the working life of bearing.
Description of drawings
Fig. 1 is a schematic cross-section of the present utility model.
Fig. 2 is the schematic representation of oil lamella in the utility model.
