What should be considered when using spherical roller bearings?

Spherical roller bearings are divided into symmetrical spherical roller bearings and asymmetrical spherical roller bearings according to the shape of the roller section. Asymmetrical spherical roller bearings are early products and mainly serve the maintenance of the main motor. Symmetric spherical roller bearings are rarely used in the new design of the main motor. The internal structure has been comprehensively improved and optimized. Compared to the early production of spherical roller bearings, they can withstand greater axial load.

What should be considered when using spherical roller bearings?

The preload force of the spherical roller bearing is carried out at room temperature, but in the operating state, the drive shaft will change the bearing preload force by the micro-expansion temperature of the system, so the set preload force should be taken into account this factor.

spherical roller bearings must have the ability to adjust the size, speed and other conditions of reasonable use of spherical roller bearing preload to ensure the service life of the transmission. If the preload is too high, the power consumption can even lead to overheating. If the preload is too low, under the action of the body load, the rolling of the shaft and the gap between the outer rings, there will be banging, running and the transmission accuracy will be increased to reduce noise, affect tooth engagement and severely damage teeth and bearings.

How are spherical roller bearings heated in an oil bath?

The heating method for oil tanks is a widely used traditional heating method. A metal grid is installed at a distance of 50–70 mm from the bottom of the oil tank, and the spherical roller bearing is placed on the grid. The large bearing should be raised by hooks and should not be placed directly on the tank floor, to avoid contact The bearing parts on the bottom of the tank are heated too strongly locally or the dirt deposited on the bottom of the tank gets into the heating method of the storage oil tank The following points must be observed in the heating method: Non-corrosive mineral oil with good thermal stability should be used, preferably transformer oil Both oil and a container should be used The capacity of the oil tank should be kept clean should be determined by the size and oil volume of the heated spherical roller bearing. If the tank is too small, in continuous operation, the oil temperature drops quickly after the bearing is inserted, and the effect is not good.

What are the advantages of spherical roller bearings compared to other products of the same type?

Like spherical ball bearings, spherical roller bearings are self-aligning, but due to the large contact area between the rollers and the raceway surface, their frictional capacity exceeds that of spherical ball bearings at far roller bearings also have a large frictional resistance during rotation, the limited speed of this type of bearing is lower than that of the ball bearing, but differs from the linear contact between the roller and the raceway in tapered roller bearing is higher than in tapered roller bearings.
