Abstract

The invention discloses a kind of manufacturing methods of novel oil-free bearing, it is characterized by comprising by polyflon material, the mixture of metal powder and molybdenum disulphide powder carries out high temperature sintering and is pressed into shaping, turning is ground into required geomery after cooling, it compares with the prior art, the beneficial effects of the present invention are: such novel oil-free bearing has self-lubrication, addition lubricating oil is not needed, the bearing powder fallen under high-speed friction is sticked on bearing the lubricant effect that can also increase bearing, the addition of metal powder makes bearing have good thermal conductivity, with high intensity, creep resistance, high temperature resistant and transcalent characteristic, the service life is longer for bearing.

Description

A kind of manufacturing method of novel oil-free bearing
Technical field
The present invention relates to a kind of method field of manufacturing, and in particular to be a kind of novel oil-free bearing manufacturing method.
Background technique
The bearing of existing wall-breaking machine or fan generallys use lubricating oil and is lubricated, the meeting more than ultrahigh speed (8000rpm) There is the case where losing oil abrasion damage, shaft expansion and bearing seizure can be made in the high temperature for the generation that runs at high speed, reduce making for bearing With the service life, the pollution for causing food materials can be sprayed in the lower lubricating oil that runs at high speed.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of manufacturer of the novel oil-free bearing of more wear resistant non lubricant oil Method.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of manufacturing method of novel oil-free bearing, including by polyflon material, metal powder and curing The mixture of molybdenum powder carries out high temperature sintering and is pressed into shaping, and turning is ground into required geomery after cooling.
As a preferred solution of the present invention, the temperature of the high temperature sintering be 360~390 degrees Celsius, high temperature sintering when Between be 3~12 hours.
As a preferred solution of the present invention, the weight ratio of the mixture are as follows: polyflon 40%~60%, gold Belong to powder 40%~60% and molybdenum disulfide 0%~15%.
As a preferred solution of the present invention, the metal powder is copper powder.
As a preferred solution of the present invention, the mesh number of the metal powder is 200 mesh or more.
It compares with the prior art, the beneficial effects of the present invention are: such novel oil-free bearing has self-lubrication, is not required to Lubricating oil is added, the bearing powder fallen under high-speed friction is sticked on bearing the lubricant effect that can also increase bearing, metal The addition of powder makes bearing have good thermal conductivity, has high intensity, creep resistance, high temperature resistant and transcalent characteristic, bearing The service life is longer.
Specific embodiment
Below with reference to embodiment further explanation of the present invention, but the invention is not limited in any way.
Embodiment 1
A kind of manufacturing method of novel oil-free bearing, including by weight ratio be 40% polyflon material, 58% copper powder and 5% molybdenum disulphide powder mixture 370 ° to 390 ° at a temperature of be stirred, 6 hours of high temperature sintering After be pressed into shaping, it is cooling after turning be ground into required geomery.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims Variation is included within the present invention, and any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art The other embodiments being understood that.
