Split spherical roller bearings are mainly used in places where the bearings are difficult to install, such as long drive shafts or crankshafts with multiple support points, in the case of integral bearings that are difficult to maintain, especially when replacing bearings In the case of very expensive occasions or when the equipment does not allow downtime for maintenance, split bearings provide the best solution.
LMM has successfully developed split bearings that can be installed anytime and anywhere, especially for the transmission and conveying roller table in the continuous casting cooling zone. The cast steel bearing seat is cooled by water, and there is a cooling inner cavity with a small section on the top of the bearing seat. Because the standard design only allows half of the outer ring of the bearing to be placed on the seat of the housing.
Design
Split spherical roller bearings are mainly developed based on the integral standard spherical roller bearings, which represent the current development level of bearing technology.
All split bearings have a cylindrical bore, and there are oil grooves and oil holes on the outer diameter of the outer ring, making it easier for lubrication to enter the cavity of the bearing.
The connecting section of the inner rings of the two parts of the bearing forms an angle with the center line of the bearing to improve the rolling conditions after the connection: the rotation is smooth, and the inner and outer rings and cages of the entire bearing are split in the center. The split inner rings are connected with bolts or clamps.
BSR.1- inner rings are connected with bolts, two split cage assemblies, and the solid brass cage is positioned by the inner ring.
BSR.2 – The flanges at both ends of the inner ring are clamped by two unfastened split clamps, and the physical cage is positioned by the inner ring.
The overall dimensions of split bearings have not yet been standardized.
Split bearings are self-aligning, and the allowable angular alignment error between the shaft and the bearing seat is 1-1.5°.
