Abstract

The utility model relates to a maintenance-free ball bearing which comprises an outer ring, an inner ring, a support and a ball, wherein the outer ring comprises a steel layer, a transition layer, a ceramic layer and a solid powder layer from outside to inside, the inner ring comprises a steel layer, a transition layer, a ceramic layer and a solid powder layer from inside to outside, sealing elements are arranged on two sides of the outer ring and the inner ring by virtue of clamping grooves. The maintenance-free ball bearing provided by the utility model has the beneficial effects that the ceramic layer is abrasion resistant, corrosion resistant and high temperature resistant, the double design of the ceramic layer and a solid lubrication layer greatly enhances the self-lubricating property of the bearing, the sealing elements have sealing effect, so that the bearing can be free from maintenance in a considerable long time.

Description

A kind of non-maintaining ball bearing
Technical field
The utility model relates to a kind of non-maintaining ball bearing.
Background technique
At the bearing that some special occasions use, as the bearing on the wind power generation fan, sand and dust content is big in the air; Some small hydropower stations and for example, water in air vapour content is big; Little in these working strengths, but the working environment complexity is difficult in maintenance, the several years is just safeguarded workplace once, bearing need not safeguarded and proper functioning in the complex work environment for a long time.Existing bearing all needs certain interval of time to add lubricant oil and carries out respective dimension and protect, and does not also have a kind of bearing of safeguarding of not needing substantially in whole working life, to satisfy the user demand of some special occasions.
The model utility content
The purpose of this utility model provides a kind of non-maintaining ball bearing, so that a kind of bearing of safeguarding of not needing substantially to be provided.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of non-maintaining ball bearing, comprise outer ring, inner ring, support and ball, described outer ring comprises firm layer, transition layer, ceramic layer and pressed powder layer from outside to inside, described inner ring comprises firm layer, transition layer, ceramic layer and pressed powder layer from inside to outside, and described outer ring and inner ring both sides are provided with Sealing by draw-in groove.
Further, described transition layer is the ferroaluminium layer.
Further, described pressed powder layer is the signal bronze powder.
The beneficial effects of the utility model are: a kind of non-maintaining ball bearing that the utility model provides, and ceramic layer is wear-resistant, corrosion-resistant, high temperature resistant; Ceramic layer and solid lubricant layer double design have strengthened the self-lubricating property of bearing greatly, Sealing have a sealing effect, allow bearing in considerable time, avoid safeguarding.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the plan view of the described non-maintaining ball bearing of the utility model embodiment.
Among the figure:
1, outer ring; 2, inner ring; 3, support; 4, ball; 5, firm layer; 6, transition layer; 7, ceramic layer; 8, pressed powder layer; 9, Sealing.
Embodiment
As shown in Figure 1, the described a kind of non-maintaining ball bearing of the utility model embodiment, comprise outer ring 1, inner ring 2, support 3 and ball 4, described outer ring 1 comprises firm layer 5, transition layer 6, ceramic layer 7 and pressed powder layer 8 from outside to inside, described inner ring 2 comprises firm layer 5, transition layer 6, ceramic layer 7 and pressed powder layer 8 from inside to outside, and described outer ring 1 and inner ring 2 both sides are provided with Sealing 9 by draw-in groove.Described transition layer 6 is a ferroaluminium.Described pressed powder layer 8 is the signal bronze powder.
The pottery iron and steel have outstanding resistance to wear, corrosion-resistant and resistance to high temperature, and have the good anti-mechanical shock and the combination property of thermal shock, and its cost has only 70% ~ 80% of wear-resistant alloy cast steel.The ball 4 of the bearing that the utility model provides and the contact position of ball 4 are ceramic body, and its friction factor is low.The pressed powder layer 8 of signal bronze powder constituent has extremely outstanding greasy property again, and double design can allow bearing not need to install additional lubricant oil in working life, avoids safeguarding.Sealing 9 allows and can keep clean at the big working environment middle (center) bearing of some dust contents, guarantees that further it exempts from greasy property.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but on its shape or structure, do any variation; every have identical with a application or akin technological scheme, all drops within the protection domain of the present utility model.
