Abstract
The utility model belongs to the technical field of mechanical parts and relates to a bearing, in particular to a wear-resistant rust-proof bearing. The wear-resistant rust-proof bearing comprises an outer ring (5), an inner ring (1), a roller (3) and flat retaining rings (2), wherein the outer ring (5) is coaxial with the inner ring (1); the flat retaining rings (2) are fixed at the upper end and the lower end of the inner ring (1); the inner wall of the outer ring (5), the outer wall of the inner ring (1) and the flat retaining rings (2) surround an annular roller groove; the roller (3) is arranged inside the roller groove; and titanium alloy layers (4) are arranged on the inner wall of the outer ring (5), the outer wall of the inner ring (1) and the outer surface of the roller (3). The wear-resistant rust-proof bearing has the advantages of high strength, good corrosion resistance, high thermal resistance and the like and has a good application prospect in the technical field of the mechanical parts.
Description
Technical field
The utility model belongs to the component of machine technical field, relates to a kind of bearing, relates in particular to a kind of bearing of wear resistant and rustproof.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.When other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.On the bearing of high speed shaft, must realize good lubricating, the bearing that has itself has had lubricated, is called prelubricated bearing; And most bearing must have lubricant oil; Load on when running up, because friction not only can increase energy consumption, more fearful is to be easy to damage bearing.
Summary of the invention
The purpose of the utility model is to overcome the defective that the existing technology middle (center) bearing is not wear-resisting and get rusty easily, and a kind of bearing of wear resistant and rustproof is provided, and between inner ring, outer ring and roller, is equipped with titanium alloy layer, effectively guarantees the wear resistant and rustproof function of bearing.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of bearing of wear resistant and rustproof; Comprise outer ring, inner ring, roller and loose rib; Outer ring and inner ring are coaxial, and loose rib is fixed on inner ring two ends up and down, and outer ring inwall, interior ring outer wall peace back-up ring surround the roller groove of annular; Roller is located in the roller groove, and outer ring inwall, interior ring outer wall and roller outer surface are equipped with titanium alloy layer.
As preferably, titanium alloy layer is titanium-molybdenum alloy layer or titanium-palladium alloy layer.
The utlity model has intensity height, good, the heat resistance advantages of higher of corrosion resistance, not only unit strength height, good rigidly, light weight are worked in the atmosphere of humidity and seawater medium, and its corrosion stability is much better than stainless steel; Resistivity to spot corrosion, acid etching, stress corrosion is strong especially; Organic article of alkali, chloride, chlorine, nitric acid, sulfuric acid etc. there is good anti-corrosion capacity.The utility model has good prospects for application in the component of machine technical field.
Description of drawings
Fig. 1 is the bearing cross-sectional structure schematic representation of the described a kind of wear resistant and rustproof of the utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1.
Embodiment
A kind of bearing of wear resistant and rustproof; Shown in Fig. 1 to 2, comprise outer ring 5, inner ring 1, roller 3 and loose rib 2, outer ring 5 is coaxial with inner ring 1; Loose rib 2 is fixed on inner ring, and about in the of 1 two ends; Outer ring 5 inwalls, inner ring 1 outer wall and loose rib 2 surround the roller groove of annular, and roller 3 is located in the roller groove, and outer ring 5 inwalls, inner ring 1 outer wall and roller 3 outer surfaces are equipped with titanium alloy layer 4.Titanium alloy layer 4 is titanium-molybdenum alloy layer.The utlity model has intensity height, good, the heat resistance advantages of higher of corrosion resistance, in the atmosphere of humidity and seawater medium, work, its corrosion stability is much better than stainless steel; Resistivity to spot corrosion, acid etching, stress corrosion is strong especially; Organic article of alkali, chloride, chlorine, nitric acid, sulfuric acid etc. there is good anti-corrosion capacity.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
Claims (2)
1. the bearing of a wear resistant and rustproof; Comprise outer ring (5), inner ring (1), roller (3) and loose rib (2); Outer ring (5) and inner ring (1) are coaxial, and loose rib (2) is fixed on inner ring (1) two ends up and down, and outer ring (5) inwall, inner ring (1) outer wall and loose rib (2) surround the roller groove of annular; Roller (3) is located in the roller groove, it is characterized in that: outer ring (5) inwall, inner ring (1) outer wall and roller (3) outer surface are equipped with titanium alloy layer (4).
