Rolamentos Esféricos
- Diâmetro Externo: 602mm~4726mm
- Bore diameter: 30mm~75mm
- Carga Nominal: 129kN~3410kN
Rolamentos Esféricos feature two rows of rolos with a common spherical raceway in the outer anel. The inner anel has two raceways that are inclined at an angle relative to the rolamento axis, and the curvature center of the outer raceway is consistent with the rolamento center.
Rolamento de Rolos Esféricos is self-aligning rolamento and consequently insensitive to errors of alignment of the eixo relative to the carcaça, and to the deflection of eixo. It automatically compensates for the angular errors caused by eixo flexing and misalignments. In addition to Carga Radial, the rolamento can also carry bidirectional axial loads and the combined loads, featuanel a large rolamento capacity, and good vibration and impact resistance.
Rolamentos Esféricos are the most widely used rolamentos in the machinery industry, commonly found in Várias mechanical equipment in iron and steel, Mineração, paper making, shipbuilding, textile machinery, coal mills, power and other industries.
Rolamento de Rolos Esféricos cages are optional in pressed steel cage (CC), machined brass cage (CA), two machined brass cages (MB), and pressed reinforced steel cage (E). rolamento code on the same structure may have difference and the following is the Características of common types of cages used in rolamentos esféricos.
| Types | Características |
| CC | It consists of two pressed steel cages, flangeless inner anel and a guide anel centred on the inner anel. It adopts symmetrical spherical rolos, which Características increased load carrying capacity and a longer Vida útil compared with CA. |
| CA | It consists of a one-piece machined brass cage, an inner anel with flange on both sides and a guide anel centred on the inner anel. It Características a higher limit speed and a relatively low noise. |
| MB | It consists of two pieces of machined brass cage, an inner anel with flange on both sides and one guide anel centred on the inner anel. Its performance is similar to CA, with lower load rating. |
| E | As the latest design, it uses symmetric spherical rolos, two pressed steel cages, a flangeless inner anel and guide anel centred on the cages. Guide anel around the outer anel can improve the lubricating condition on rolo face of end, by reducing friction, guiding rolo in the non-load region and assisting rolo enteanel into the load area. Meanwhile, the length of rolo is getting longer so that the load rating is greatly enhanced. Usually, the Carga Nominal can be increased by 20% -35%. |
