Abstract
The invention 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, 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 home and abroad.
Description
Technical field
The present invention relates to a kind of bearing, especially relate to a kind of outer ring spherical double-row cylindrical roller split bearing.
Background technique
At present, vitals in converter installation at steel industry middle (center) bearing, be arranged on gudgeon, use in the rugged environment of high temperature, high loading, corrosion corrosion, conventionally adopt integrated type roller bearing, this bearing has following shortcoming: 1, outer ring is cylndrical surface, there is no aligning effect, causes the life-span low; 2, while maintenance, change bearing difficulty,, reduce working efficiency.
Summary of the invention
Object of the present invention is exactly to provide a kind of longer service life in order to overcome the defect that above-mentioned prior art exists, use outer ring spherical double-row cylindrical roller split bearing more easily.
Object of the present invention 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 outer ring fastening piece by two double semi outer rings, described inner ring is connected and composed by two two half inner rings, between the inwall of outer ring and the outer wall of inner ring, form biserial raceway, roller is in retainer is arranged on biserial raceway.
Two described double semi outer rings can be installed respectively, begin a theatrical performance rank boring on a semi outer rings, on second half outer ring, offer tapped hole, and the outer ring fastening piece forming through outer ring fastening screw trip bolt and outer ring fastening spring connects.
The end face of two described double semi outer rings is provided with the mounting groove that outer ring fastening piece is installed.
Described outer ring is with the spheric structure that can make bearing self-aligning in the time that axle has deflection.
The thickness of described outer ring is 24mm, has increased intensity.
On the external diameter of described outer ring, offer oilhole, can use grease lubrication, regularly stuffing, has reduced lubrication system, provides cost savings, and has improved lubricated environment, and environmental work environment is more comfortable.
Described two two half inner rings can be installed respectively, connect through the inner ring fastening piece in outside and the inner ring fastening screw trip bolt that is arranged with 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 being arranged in raceway, gain in strength, and is convenient to install.
Compared with prior art, the present invention replaces straight roller bearing with outer ring spherical double-row cylindrical roller split bearing, and for converter installation, bearing is convenient to install and safeguard, has significantly reduced time and the expense of changing bearing, has the following advantages:
1, due to the cylindrical roller adopting, roller diameter strengthens, and length lengthens, thereby has increased bearing load, has improved the life-span;
2, outer ring band sphere, in the time that axle has deflection, bearing can 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 environmental work environment is more comfortable.
4, retainer adopts two and half copper cages, gains in strength, and is convenient to install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of two semi outer rings joints;
Fig. 3 is the structure for amplifying schematic diagram of Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
