Abstract
The utility model relates to a coated bearing. Superhard strengthening layers with N micron thickness are arranged on the surfaces of a bearing inner ring, a bearing outer ring, a rolling body and a holding frame. Self lubricating film with M micron thickness is arranged outside the N micron thick superhard strengthening layers on the surfaces of a bearing inner ring, a bearing outer ring, a rolling body and a holding frame. Compared with the prior art, the surface hardness of all the positions of the bearing is improved, the friction coefficient among the positions is reduced, the coated bearing can be provided with better function and quality, in order to ensure the hardness of the bearing not to be reduced because of coating, simultaneously, to ensure the quality stability of mass coated bearings (the bonding strength of the coating and the thickness tolerance precision), and to improve the stability of the appearance and the quality.
Description
Technical field
The utility model relates to a kind of plated film bearing, specifically belongs to material surface modifying promptly by physical vapor deposition and other coating technique, plates the superhard plated film bearing made from lubricating film of one deck on each surface, position of bearing, to improve the effect and the quality of bearing.
Background technique
Bearing is the supporting member in the mechanical transmission mechanism, and its quality directly influences the service behaviour of mechanical complete machine.Bearing bears complicated applied forces such as pressure, shearing and tired impact friction in the course of the work.Bearing is because of the position difference, the power of bearing is different, but in the prior art, the material material of each bearing is the same, the deficiency that exists is: stressed big local wearing and tearing earlier often make bearing failure owing to bearing a part surface abrasion small pieces peel off or are out of shape.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art a kind of each position surface hardness of bearing that improves is provided, and reduces the plated film bearing of the friction factor between them.
The technical solution of the utility model comprises bearing inner race, bearing outer ring, rolling element, retainer, and the superhard strengthened layer of N micron thickness is arranged on bearing inner race, bearing outer ring, rolling element and retainer surface.
The superhard strengthened layer of the said N micron thickness of the utility model, wherein N is 2～8.
The utility model has the self-lubricating film of M micron thickness outside the superhard strengthened layer of N micron thickness on bearing inner race, bearing outer ring, rolling element and retainer surface.
The self-lubricating film of the said M micron thickness of the utility model, wherein M is 1～3.
The said plated film bearing outward appearance of the utility model has two or more colors: bearing inner race, bearing outer ring, rolling element are that roller, steel ball, needle roller are grey or grey black look, and retainer is golden, improves appearance quality and rustless property.
The application on mechanical parts such as cutting tool, mould since the last century the eighties of titanium nitride (TIN) physical vapor deposition (PVD) technology is more extensive, improved the quality of some products, in 21st century PVD technology new development has been arranged again especially, the exploitation of multiple new plated film composition is for condition has been created in the PVD application of bearing.The utility model is based on new bearing plated film theory, i.e. overcoat in bearing, rolling element (roller, steel ball, needle roller), the retainer surface plates several microns superhard and solid lubricant film, compared with prior art, the utility model has improved each position surface hardness of bearing, reduced the friction factor between them, make plated film bearing that better function and quality be arranged, to guarantee that bearing can be because of the hardness of plated film reduction own, guarantee the mass stability (rete adhesive strength and thickness deviation precision) of plated film bearing in enormous quantities simultaneously, and improve bearing exterior quality stability.
Description of drawings
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
In the accompanying drawing, the utility model comprises bearing inner race 2, bearing outer ring 4, rolling element 3, retainer 1, and the superhard strengthened layer 5 of 5 micron thickness is arranged on bearing inner race 2, bearing outer ring 4, rolling element 3 and retainer 1 surface.This superhard strengthened layer 5 is nitride, carbide or the nitride superhard film of chromium nitride (CRN), charing chromium (CRC), charing zirconium (ZRC), titanium nitride III-II transition elements such as (TIN).The self-lubricating film 6 that 2 micron thickness are arranged outside the superhard strengthened layer 5 on bearing inner race 2, bearing outer ring 4, rolling element 3 and retainer 1 surface.Self-lubricating film 6 is molybdenum disulfide (N
0S
2), tungsten disulfide (WS
2), DLC (DLC) lubricating film.The utility model outward appearance has two kinds of colors: bearing inner race 2, bearing outer ring 4 and rolling element 3 are grey, and retainer 1 is golden.
The utility model adopts low temperature physical coating (PVD) technology and the equipment and the special frock clamping of unique design, to guarantee that bearing can be because of the hardness of plated film reduction own, guarantee the mass stability (rete adhesive strength and thickness deviation precision) of plated film bearing in enormous quantities simultaneously, and improve bearing exterior quality stability.
