Abstract

The utility model relates to a rolling mill sealing bearing for a rolling mill, which is composed of an outer ring, an inner ring, a holder and a rolling body. The utility model is characterized in that the outer ring, the inner ring and the rolling body of the rolling mill sealed bearing are made of vacuum degassed steel; two sealing rings are arranged between the outer ring and the inner ring. The rolling mill sealing bearing of the utility model is made of vacuum degassed steel having good quality, the material purity is high, the gas content is less, the rated load of a bearing can be improved, and the service life can be extended. The sealing rings are arranged between the outer ring and the inner ring, the service life of the rolling mill bearing can be extended by more than three times, the consumption of machine oil is reduced, and the environmental pollution is avoided.

Description

The milling train sealed bearing

Technical field

The utility model relates to the milling train sealed bearing that a kind of rolling mill is used.

Background technology

The bearing that rolling mill is used is divided into two kinds on sliding bearing and rolling bearing, belongs to general quick-wear part, at present, the domestic rolling bearing that tradition is used on rolling mill, mainly by: outer ring, inner ring, retainer and rolling element four parts are formed.Because the rolling mill bearing will bear high load capacity, high rotary speed working, there are water spray, cooling, steam to splash in the surrounding environment, there are iron rust, iron phosphorus impurities to fly upward again, if these impurity are invaded the rolling mill bearing inside of rotation at a high speed, can make bearing very quick-wearing scrap, simultaneously can also cause lubricating oil loss contaminated environment.Analyze from economic benefit in addition, according to incompletely statistics, domestic rolling mill has thousands of groups, needs on every group of rolling mill with tens cover bearings, have only tens days the service life of every cover rolling mill bearing, and therefore the annual expense that consumes on the rolling mill bearing is just picked up hundred million RMB up to number with regard to the whole nation.How to improve rolling mill bearing service life, reduce production costs, reduce environmental pollution, increase economic efficiency, become the scientific research task that the insider pays close attention to most.

Summary of the invention

The purpose of this utility model is to provide a kind of milling train sealed bearing with long service life, non-environmental-pollution for rolling mill.

The utility model milling train sealed bearing content Description:

The utility model milling train sealed bearing, by: outer ring, inner ring, retainer and rolling element are formed, and it is characterized in that: the outer ring of milling train sealed bearing, inner ring and rolling element are to adopt vacuum-degassed steel to make, and two sealing rings are set between outer ring and inner ring.

The utility model milling train sealed bearing selects for use the vacuum-degassed steel of high-quality to make, and the rated load that material purity height, air content be few, can improve bearing, increases the service life.Between outer ring and inner ring, sealing ring is set, can prolongs rolling mill bearing service life more than 2 times, and reduced consumption of lubricating oil, avoided environmental pollution.

Description of drawings

Fig. 1 is a milling train sealed bearing structure schematic diagram

Among Fig. 1: 1 is that outer ring, 2 is that inner ring, 3 is that rolling element, 4 is that retainer, 5 is sealing ring.

The specific embodiment

The utility model milling train sealed bearing is to realize like this, see Fig. 1, form by outer ring 1, inner ring 2, rolling element 3, retainer 4, sealing ring 5, the outer ring 1 of milling train sealed bearing, inner ring 2 and rolling element 3 are to adopt vacuum-degassed steel to make, because material purity height, air content are few, the rated load that can improve bearing, increase the service life.Two sealing rings 5 are set between outer ring 1 and inner ring 2, have avoided introduced contaminants to invade bearing inside, can avoid bearing to scrap because of wearing and tearing, can also prevent that machine oil run off more than 2 times the service life of improving bearing, reduces the machine oil loss, avoids environmental pollution.

Claims

1, a kind of milling train sealed bearing, by: outer ring, inner ring, retainer and rolling element are formed, and it is characterized in that: the outer ring of milling train sealed bearing, inner ring and rolling element are to adopt vacuum-degassed steel to make, and two sealing rings are set between outer ring and inner ring.
