Abstract
The invention relates to a coated bearing, which is produced by coating a coating layer on each component of the bearing including an internal sleeve, an external sleeve, a rolling body and a holder by titanium nitride (TIN) physical vapor deposition (PVD) and other surface coating techniques. The coating layer comprises a hard coating layer and a self-lubricating film layer. The inventive coated bearing has more than two colors on appearance: the internal and the external sleeves of the bearing, and the rolling body (i.e. rollers, steel balls and roller pins) are grey or dark grey, and the holder is golden. Compared with the prior art, the invention improves the surface hardness of each component of the bearing and reduces the friction coefficient between components, so that the bearing has better function and quality, thereby enabling the bearing not to reduce the hardness due to the coated film and ensuring quality stability of the coated bearings in a large quantity (film layer binding strength and thickness tolerance precision), and improving the appearance quality stability of the bearing.
Description
Technical field
The present invention relates to a kind of plated film bearing, specifically belong to material surface modifying, plate 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 promptly by physical vapor deposition and other coating technique.
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 objective of the invention is to overcome the deficiencies in the prior art provides a kind of each position surface hardness of bearing that improves, and reduces the plated film bearing of the friction factor between them.
Technical program of the present invention lies in: this bearing is to plate the plated film bearing product that coating is made on interior overcoat, rolling element and the retainer by adopting titanium nitride (TIN) physical vapor deposition (PVD) and other surface coating technology to comprise at the bearing each several part.
The said coating of the present invention is hard coating and selflubricating rete.
The said coating of the present invention is the N micron thickness hard coating on bearing inner race, bearing outer ring, rolling element and retainer surface.
The hard coating of the said N micron thickness of the present invention, wherein N is 2～8.
The said hard coating of the present invention composition 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 said coating of the present invention is for there being the selflubricating rete of 1～3 micron thickness outside the N micron thickness hard coating on bearing inner race, bearing outer ring, rolling element and retainer surface.
The said plated film bearing outward appearance of the present invention has two or more colors: overcoat, rolling element are that roller, steel ball, needle roller are grey and grey black look in the bearing, and retainer be a gold.
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 present invention is based on new bearing plated film theory, promptly overcoat, rolling element (roller, steel ball, needle roller), retainer surface plate several microns superhard and solid lubricant film in bearing, compared with prior art, the present invention 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 improved bearing exterior quality stability.
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the present invention.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
In the accompanying drawing, the present invention includes bearing inner race 2, bearing outer ring 4, rolling element 3, retainer 1, the hard coating 5 of 5 micron thickness is arranged on bearing inner race 2, bearing outer ring 4, rolling element 3 and retainer 1 surface.This hard coating 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 selflubricating rete 6 that 2 micron thickness are arranged outside the hard coating 5 on bearing inner race 2, bearing outer ring 4, rolling element 3 and retainer 1 surface.Selflubricating rete 6 is molybdenum disulfide (N
0S
2), tungsten disulfide (WS
2), DLC (DLC) lubricating film.Outward appearance of the present invention has two kinds of colors: bearing inner race 2, bearing outer ring 4 and rolling element 3 are grey, and retainer 1 is golden.
(1) adopt special low-temperature physics gas phase deposition technology (PVD) to plate plated film bearing product superhard and that solid profit face is made at the bearing each several part.
(2) plate several microns above-mentioned different superhard films or superhard and self-lubricating composite membrane by bearing species overcoat, rolling element (roller, steel ball, needle roller) surface in bearing, retainer plates titanium nitride (TIN) and the plated film bearing that is assembled into.
(3) the bearing outward appearance has two or more color and lusters, and promptly overcoat, rolling (roller, steel ball, needle roller) are grey or grey black look in the bearing, and retainer is golden, improves appearance quality and rustless property.
The present invention 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.
