Abstract
The invention provides a low-speed self-lubricating high-temperature rolling bearing convenient for lubrication maintenance. The rolling bearing comprises an inner ring, an outer ring, rolling elements, two dust caps and two graphite blocks, the number of actually used rolling elements is equal to the difference of the number of full-loaded rolling elements and 1, the two graphite blocks are located between the inner ring and the outer ring, the graphite blocks and the rolling elements form an annular structure, the rolling elements are separated in the annular structure at an interval, two opposite surfaces of each one of the graphite blocks respectively facing to the two rolling elements adjacent to the graphite block are arc surfaces, and through the arc surfaces, the graphite blocks fit to a part of the rolling elements. In operation of the low-speed self-lubricating high-temperature rolling bearing, the graphite blocks, the adjacent rolling elements and the inner and outer rings produce uniform friction thereby producing graphite chippings, and the graphite chippings stay in a rollaway nest and produce solid powder lubrication effects. The rolling elements and the inner and outer rings have high smoothness and a less disposable graphite block wear amount and thus the graphite block can continuously provide solid powder lubrication effects for the bearing for a long time. The bearing is convenient for lubrication maintenance.
Description
technical field
The present invention relates to a kind of low speed selflubricating high temperature rolling bearing.
background technique
In order to improve the bearing capacity of rolling bearing, existing low speed high temperature rolling bearing is the full dress rolling element structure removing retainer, usually adopts high temperature lubricating grease lubrication.Low speed high temperature rolling bearing works in high temperature environments, first lubricant component in the high temperature grease of initial filling evaporates, only residual solids composition plays lubrication, this solid constituent amount is less, is not enough to maintain the long good lubrication of low speed high temperature rolling bearing, therefore needs high temperature grease of again annotating in a short time, due to the reason such as special construction and elevated-temperature seal, cause filling to operate inconvenience, could annotate after also needing stopping production to wait bearing cooling if desired, make maintenance cost higher.If do not annotated, high temperature grease continues to use, and will cause low speed high temperature rolling bearing early failue, changes bearing cost higher.Due to the impact of bearing self structure and position, part low speed high temperature rolling bearing can not adopt pressed powder to lubricate, when bearing can adopt pressed powder to lubricate, pressed powder lubrication retention amount in raceway is limited, and in bearing operation process, pressed powder is easily pushed out outside bearing, and pressed powder consumption is fast, and lubrication effect is still poor.
summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low speed selflubricating high temperature rolling bearing being convenient to lubricated maintenance.
In order to solve the problems of the technologies described above, technological scheme of the present invention is:
A kind of low speed selflubricating high temperature rolling bearing, comprise inner ring, outer ring, rolling element, two dust covers and two graphite blocks, rolling element quantity=completely fill rolling element quantity-1, two graphite blocks also form ring structure between Internal and external cycle together with rolling element, two graphite blocks are spaced apart setting in loop configuration, each graphite block is arc shaped surface towards the two relative side of two rolling elements adjacent with this graphite block respectively, and this arc shaped surface makes graphite block and part rolling element match.
Above-mentioned low speed selflubricating high temperature rolling bearing, the distance between two graphite blocks that the position of two graphite blocks in loop configuration should make maximizes.
Above-mentioned low speed selflubricating high temperature rolling bearing, the curvature of arc shaped surface and rolling element is close.

Embodiment
As shown in Figures 1 to 5, low speed selflubricating high temperature rolling bearing comprises inner ring 4, outer ring 2, rolling element 3, two dust cover 5 and two graphite blocks 1.Rolling element quantity=completely fill rolling element quantity-1, namely this bearing does not install retainer, still adopts full dress rolling element structure, just during assembling rolling element, fills 1 rolling element less, to reserve the assembly space of graphite block.Two graphite blocks also form ring structure between Internal and external cycle together with rolling element, and outer the moving that two dust covers limit two graphite blocks makes two graphite blocks operate in bearing.Two graphite blocks are spaced apart setting in loop configuration, each graphite block is arc shaped surface towards the two relative side of two rolling elements adjacent with this graphite block respectively, this arc shaped surface makes graphite block and part rolling element match, the setting of arc shaped surface increases the area of contact of graphite block and adjacent rolling elements, reduces contact stress.
Distance between two graphite blocks that the position of two graphite blocks in loop configuration should make maximizes, and such as, when rolling element is even number, two graphite blocks are oppositely arranged centered by bearing centre; When rolling element is odd number, two graphite blocks are substantially oppositely arranged centered by bearing centre.
The curvature of arc shaped surface and rolling element is close, and maximize with the area of contact of the graphite block made and adjacent rolling elements, contact stress minimizes.
In low speed selflubricating high temperature rolling bearing operation process, there is revolution and rotation in rolling element, graphite block revolves round the sun, and graphite block and adjacent rolling elements and Internal and external cycle rub and more evenly produce graphite and consider to be worth doing, then reside in raceway, play pressed powder lubrication.Due to rolling element and Internal and external cycle smoothness higher, disposable graphite block wear extent is less, therefore graphite block can for a long time incessantly for bearing provides pressed powder to lubricate.When bearing does not work, graphite block also correspondingly stops wearing and tearing, and graphite block has high-temperature stability, loss can not occur.In addition, when graphite block wearing and tearing to a certain degree need to change, only need dismantle dust cover, graphite block is changed.In sum, the present invention has the characteristic being convenient to lubricated maintenance.The invention solves low speed high temperature rolling bearing and use the technical problem that the high temperature grease life-span is short, lubricate uneven and frequent greasing, reduce bearing wear, extend working life, the type being applicable to manufacturing low speed selflubricating high temperature rolling bearing in this is deep groove ball bearing, roller bearing, needle bearing, angular contact ball bearing, roller bearing units or double-row self-aligning ball bearing.The present invention uses rotating speed to be not more than 300 revs/min.
