CN201696495U - Self-lubricating bearing - Google Patents

Abstract

The utility model relates to a self-lubricating bearing, which comprises an inner ring and an outer ring, wherein a movable bush is arranged on the inner surface of the outer ring. The utility model has the beneficial effects that: since the utility model uses an SF material as the inner layer of the movable bush, and the movable bush and the inner ring of the bearing form a pair of friction pairs, the structure is simplified, and the cost is reduced; by the analysis of mechanical performance, heat aging and thermal stability performance, the friction coefficient of the SF material is the smallest, can resist the corrosion action of oxygen, ozone and ultraviolet light, is not aged, and resist high temperature, therefore, the SF self-lubricating bearing has low running noise, long service life, small wear, and good corrosion resistance, does not need add lubricating oil often in running, and saves steel materials.

Description

A kind of self oiling bearing

Technical field

The utility model relates to a kind of self oiling bearing.

Background technique

No matter known bearing is that sliding bearing or rolling bearing all exist following shortcoming in manufacturing and using process: (1) complex manufacturing technology, and cost height, particularly rolling bearing are higher to the technological requirement of steel ball; (2) in service have certain noise, and after long-term the use, wearing and tearing are big, needs often to add lubricant oil; (3) Corrosion Protection is poor, has reduced the life-span.

The model utility content

The purpose of this utility model provides a kind of self oiling bearing, simplifies the structure, and has reduced cost, does not in servicely need often to add lubricant oil, and Corrosion Protection is good, has saved steel in addition.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of self oiling bearing comprises inner ring and outer ring, and the internal surface of described outer ring is provided with loose bush.

The beneficial effects of the utility model are: the utility model is owing to adopted the SF material to make the internal layer of loose bush, with the bearing inner race friction pair that partners, simplify the structure, reduced cost, through the SF mechanical property of materials and heat ageing, thermal stability analysis, the friction factor of SF material is minimum in the plastics, and can tolerate the corrosive action of oxygen, ozone and ultraviolet, be difficult for wearing out, high temperature resistant, therefore, SF self oiling bearing running noises is low, the life-span long, wearing and tearing are little, in servicely do not need often to add lubricant oil, Corrosion Protection is good, has saved steel in addition.

Description of drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of the described a kind of self oiling bearing of the utility model embodiment.

Among the figure:

1, inner ring; 2, outer ring; 3, loose bush.

Embodiment

As shown in Figure 1, the described a kind of self oiling bearing of the utility model embodiment comprises inner ring 1 and outer ring 2, and the internal surface of described outer ring 2 is provided with loose bush 3.

When concrete the use, the internal layer of loose bush 3 adopts the SF material, the SF material is to be major ingredient with the teflon, adding proper additive, pore former are composited, the skin of loose bush 3 adopts metallic copper, make it to be fixed on 2 inboards, outer ring, loose bush 3 and the inner ring 1 self oiling bearing friction pair that partners.

Claims (1)

1. a self oiling bearing comprises inner ring (1) and outer ring (2), and it is characterized in that: the internal surface of described outer ring (2) is provided with loose bush (3).
