Abstract
The utility model relates to a double-row cylindrical roller split bearing with a spherical outer ring. The double-row cylindrical roller split bearing comprises an outer ring, rollers, a retainer and an inner ring; the outer ring consists of two double half outer rings which are connected through outer ring fasteners; the inner ring consists of two double half inner rings which are connected together; a double-row raceway is formed between the inner wall of the outer ring and the outer wall of the inner ring; and the rollers are arranged in the double-row raceway through the retainer. Compared with the prior art, the double-row cylindrical roller split bearing with a spherical outer ring replaces a common cylindrical roller bearing and is applied to a converter device, so that the bearing is convenient to install and maintain, the time and the money for exchanging bearings are greatly reduced; because the oil lubrication is changed to grease lubrication, the lubrication system is reduced, the cost is lowered, the lubrication environment is improved, and the working environment is more comfortable, so that the iron and steel industry is improved to a new stage and reaches the advanced level at home and abroad.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of outer ring spherical double-row cylindrical roller split bearing.
Background technique
At present, vitals in the converter installation at the steel industry middle (center) bearing, be installed on the gudgeon, use is in the rugged environment of high temperature, high loading, corrosion corrosion, usually adopt the integrated type roller bearing, this bearing has following shortcoming: 1, the outer ring is the cylndrical surface, does not have the aligning effect, causes the life-span low; Change the bearing difficulty when 2, safeguarding,, reduced working efficiency.
The model utility content
The purpose of this utility model is exactly to provide a kind of longer service life in order to overcome the defective that above-mentioned prior art exists, use more easily outer ring spherical double-row cylindrical roller split bearing.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of outer ring spherical double-row cylindrical roller split bearing, comprise outer ring, roller, retainer and inner ring, described outer ring is connected and composed through the outer ring fastening piece by two double semi outer rings, described inner ring is connected and composed by two two half inner rings, consist of the biserial raceway between the inwall of outer ring and the outer wall of inner ring, roller is in retainer is arranged on the biserial raceway.
Described two double semi outer rings can be installed respectively, begin a theatrical performance rank and boring on the semi outer rings, offer tapped hole on second half outer ring, connect through the outer ring fastening piece that outer ring fastening screw trip bolt and outer ring fastening spring consist of.
The end face of described two double semi outer rings is provided with the mounting groove that the outer ring fastening piece is installed.
Described outer ring is with the spheric structure that can make bearing self-aligning when axle has deflection.
The thickness of described outer ring is 24mm, has increased intensity.
Offer oilhole on the external diameter of described outer ring, can use grease lubrication, regularly stuffing has reduced lubrication system, provides cost savings, and has improved lubricated environment, and the environmental work environment is more comfortable.
Described two two half inner rings can be installed respectively, through the inner ring fastening piece in the outside and the inner ring fastening screw trip bolt connection that is arranged with the inner ring fastening spring.
Described roller is cylindrical roller, and roller diameter is 14mm, and length is 16mm, has increased bearing load, improves working life.
Described retainer is two and half copper cages, and two ends connect respectively the roller that is arranged in the raceway, gain in strength, and is convenient to install.
Compared with prior art, the utility model replaces straight roller bearing with outer ring spherical double-row cylindrical roller split bearing, is used for converter installation, and bearing is convenient to install and safeguard, has significantly reduced time and the expense of changing bearing, has the following advantages:
1, owing to the cylindrical roller that adopts, roller diameter strengthens, and length lengthens, thereby has increased bearing load, has improved the life-span;
2, outer ring band sphere, when axle has deflection, but the bearing self-aligning has improved bearing life;
3, outer ring external diameter band oilhole can use grease lubrication, and regularly stuffing has reduced lubrication system, provides cost savings, and has improved lubricated environment, and the environmental work environment is more comfortable.
4, retainer adopts two and half copper cages, gains in strength, and is convenient to install.
