Abstract

The utility model discloses a rolling mill rolling bearing, including a bearing outer ring, a bearing inner ring, a bearing roller and a bearing bracket, characterized in that an oil filler point is provided on the bearing outer ring to match with the external circulating oiling device to make the lubricant oil circulating flow between rollers, to realize the lubrication with the maximum extent and reduction of bearing temperature. Compared with existing technologies, the utility model has the advantage of increased lubrication, reduced temperature, effectively improved bearing fail caused by high-temperature and bad lubrication, 25 to 30 percent prolonged service life of bearing, saved production costs and improved productivity.

Description

A kind of mill roller bearing

Technical field

The utility model relates to the mill roller 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 80 meter per seconds, such productivity needs the bearing per minute to change commentaries on classics up to ten thousand, and the temperature that billet material itself is 800 ℃ makes bearing be in very high ambient temperature, and present employed roller-mill bearing, under this high-speed and high-temperature environment, its rate of wear is sharply accelerated, and bearing can very fast inefficacy, and 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 mill roller 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 mill roller bearing, comprise bearing inner race, bearing outer ring, bearing roller and bearing bracket, and it is characterized in that: have oil hole on the bearing outer ring.

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, can inject the lubricant oil that circulates by oil hole, realize increasing lubricated, reduction bearing temperature, effectively improve because the bearing failure that high temperature and insufficient lubrication cause makes prolong 25% to 30% the working life of bearing, save production cost, enhance productivity.

Description of drawings

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

Fig. 2 be among Fig. 1 A-A to sectional drawing.

Among the figure:

1, bearing inner race; 2, bearing outer ring; 3, bearing roller; 4, bearing bracket; 5, oil hole.

Embodiment

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

As shown in Figure 1, a kind of mill roller bearing comprises bearing inner race 1, bearing outer ring 2, bearing roller 3 and bearing bracket 4, it is characterized in that: have oil hole 5 on the bearing outer ring 2.

Described mill roller bearing is provided with 1 above oil hole 5 on bearing outer ring 2.

As shown in Figure 1, 2, with the mill roller bearing that is provided with 3 oil holes is example, on bearing outer ring 2, offer 3 through holes, equally distributed 3 through holes are as oil hole 5, cooperate the outer loop oiling device, lubricant oil is injected and is flowed out by

different oil hole

5, and 3 formation of the bearing roller between bearing inner race 1 and bearing outer ring 2 circulate, and can take away the heat of its generation when assurance is lubricated.

Claims

1. a mill roller bearing comprises bearing inner race (1), bearing outer ring (2), and bearing roller (3), bearing bracket (4) is characterized in that: have oil hole (5) on the bearing outer ring (2).

2. mill roller bearing according to claim 1 is characterized in that: have 1 above oil hole (5) on bearing outer ring (2).
