Abstract

The utility model discloses an abrasion and high-temperature resistant rolling bearing, which comprises a bearing outer ring, a bearing inner ring, bearing rollers and a bearing support. The bearing is characterized in that a nano ceramic coating layer is respectively sprayed on the inner wall of the bearing outer ring, the outer wall of the bearing inner ring and the outer surfaces of the bearing rollers. Compared with the prior art, the bearing has the advantages of reducing bearing failure caused by high temperature and high speed abrasion by adding the nano ceramic coating layer with characteristics of high-temperature and abrasion resistance, and prolonging service life of a ceramic bearing to be more than three times of ordinary bearings.

Description

The Wear-resistant, high-temperature resistant rolling bearing

Technical field

The utility model relates to Wear-resistant, high-temperature resistant rolling bearing field, particularly a kind of used roller-mill bearing of iron and steel enterprise's high-speed wire production line that is used for.

Background technique

On iron and steel enterprise's high-speed wire production line, milling train is produced wire rod with the rolling 800 ℃ steel billet of the speed of 90～105 meter per seconds, such productivity needs the bearing per minute to change commentaries on classics up to ten thousand, the temperature that billet material itself is 800 ℃ makes bearing be in very high ambient temperature, and present employed roller-mill bearing mostly is the steel bearing, under this high-speed and high-temperature environment, its rate of wear is sharply accelerated, bearing can very fast inefficacy, too early bearing failure meeting causes the shut-down of entire equipment, reduce manufacturing efficiency, increased cost of production.

The model utility content

Technical problem to be solved in the utility model is, at above-mentioned prior art present situation, provides a kind of Wear-resistant, high-temperature resistant rolling bearing product of simple, long service life.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of Wear-resistant, high-temperature resistant rolling bearing, comprise bearing inner race, bearing outer ring, bearing roller and bearing bracket, it is characterized in that: bearing outer ring inwall, bearing inner race outer wall and bearing roller outer surface are coated with nano ceramic coat.

Compared with prior art, advantage of the present utility model is, simple in structure, it is convenient to use, and has increased the working life of bearing greatly, and the nano ceramics friction ractor is low, hardness is high, lubricating ability is higher than traditional steel axle far away, its material itself has the characteristic that heat resistant and wear resistant decreases, because high temperature and the bearing failure that causes of wearing and tearing at a high speed, this NANO Ceramic Bearing working life is more than 3 times of plain bearing by increasing that this nano ceramic coat can effectively improve.

Description of drawings

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the partial enlarged drawing of I among Fig. 1.

Among the figure:

1, bearing inner race; 2, bearing bracket; 3, bearing outer ring; 4, bearing roller; 5, nano ceramic coat.

Embodiment

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

As shown in Figure 1, a kind of Wear-resistant, high-temperature resistant rolling bearing comprises bearing inner race 1, bearing bracket 2, and bearing outer ring 3, bearing roller 4 is characterized in that: bearing outer ring 3 inwalls, bearing inner race 1 outer wall and bearing roller 4 are coated with nano ceramic coat 5 in appearance.

As shown in Figure 1, during the bearing element state, mutual friction mutually between the inwall of bearing outer ring 3 and bearing roller 4 outer walls and bearing inner race 1 outer wall and bearing roller 4 outer walls.As shown in Figure 2, increase nano ceramic coat 5 at bearing outer ring 3 inwalls, telogenesis increases nano ceramic coat outside bearing inner race 1 outer wall and bearing roller 4 equally, strengthens its wear-resisting and resistance to high temperature.

Claims (1)

1. Wear-resistant, high-temperature resistant rolling bearing, comprise bearing inner race (1), bearing bracket (2), bearing outer ring (3), bearing roller (4) is characterized in that: bearing outer ring (3) inwall, bearing inner race (1) outer wall and bearing roller (4) outer surface are coated with nano ceramic coat (5).
