Description
Technical field
The present invention relates to field of mechanical technique, more particularly to heavily loaded high-temperature self-lubrication rolling bearing and processing technology.
Background technique
With the development of Mechanical Industry Technology, the design and fabrication technology of bearing has also obtained development in an all-round way, and bearing has
The extensive feature of application surface.A kind of conventional machinery structure of the bearing as mechanical industry, plays receiving to the mechanism mutually rotated
Load, the effect for reducing frictional resistance, improving machinery driving efficiency.
In the prior art, there are many type of heavy-duty bearing, by the frictional property of bearing working, can be divided into sliding friction axis
It holds and rolling friction bearing two major classes；The load that can bear by it can be divided into: 1. transverse bearing or radial bearing, this
Bearing bears radial load；2. thrust bearing or thrust bearing, this bearing bears axial load；3. radical-thrust axis
It holds, or referred to as radial thrust bearing, this bearing can bear radial load and axial load simultaneously；
Sliding bearing, also without rolling element, is made regardless of Internal and external cycle of wear-resistant material, and this bearing is usually used in low speed, again
It carries and filling lubricating oil and the relatively difficult mechanical rotary part of maintenance；Rolling bearing is the axis and axle bed that will be operated
Between sliding friction become rolling friction, to reduce a kind of mechanical organ of friction loss；Rolling bearing generally by outer ring,
Inner ring, rolling element and retainer composition, rolling bearing working service is convenient, and bearing capacity is higher under medium speed；Sliding axle
Hold it is bigger than the coefficient of friction of rolling bearing, so, for improve mechanical efficiency, traditional mechanical rotational structure mostly design and use
Rolling bearing；
And the bearing of currently used this heavy duty, the load under rotation because of receiving are larger, and then when being worked,
Since the increase of frictional force can generate high temperature, causes the lubricant in bearing to be easy failure in the event of high temperatures, cause heavy duty
The security risk that bearing uses；It usually solves the problems, such as such, to generally use high temperature rolling bearing, is the gold in bearing matrix
Belong to and output the hole that size is appropriate, orderly aligned on rubbing surface, then insertion has the molding of self-lubricating property solid in hole
Body lubricant and manufactured self-lubricating bearing bear load by metallic matrix high-tensile strength brass.General this formation solid lubricant
Using graphite or molybdenum disulfide, for the latter's general work temperature within 300 DEG C, the former operating temperature, can not within 800 DEG C
It is applicable in high revolving speed, high environment temperature field；In addition, it is easy to occur spot corrosion or line erosion on bearing internal external circle, so-called spot corrosion is just
It is to be easy to form microcosmic pit or line hole, these pits on the channel of relatively low curvature when rolling element and channel contact
Or the presence in line hole makes bearing occur effect of climbing in the process of running, in-fighting is big, noise is big and vibration is big, in this operation shape
Easily make bearing generate fatigue under state to damage, to influence the use longevity of heavy-duty bearing.
