Performance and characteristics of thrust spherical roller bearings:
First of all, we need to understand what is a thrust spherical roller bearing, which is a thrust bearing with Peng-shaped rollers arranged obliquely. The raceway of the seat ring is spherical and has the function of self-aligning. The imported thrust spherical roller bearing is a separate roller bearing. The cage includes the shaft ring and spherical rollers into one component, and the seat ring and the component can be separated. This kind of imported bearing is suitable for working at high speed and is mostly used for the main shaft of oil drilling rigs.
The performance and characteristics of thrust spherical roller bearings: the outer ring of spherical roller bearings should not adopt interference fit with the housing hole of the bearing seat, and the fit between the inner ring and the shaft journal should not be too tight, and it is required to use nuts to adjust during installation. It should be able to make it produce more flexible axial displacement. Because if the self-aligning roller bearing adopts interference fit, it is easy to change the contact angle of the bearing, resulting in uneven distribution of bearing load and high temperature rise. Therefore, the installation and coordination of the inner and outer rings of this type of bearing with the journal and the housing hole of the bearing seat should generally be the best when the thumbs of both hands can just push the bearing into the journal and the housing hole.
Performance and characteristics of thrust spherical roller bearings: For the installation axial clearance of spherical roller bearings, the adjusting nut on the journal, the adjusting gasket and the thread in the bearing seat hole can be used, or the method of preloading the spring can be used. Make adjustments. The size of the axial clearance is related to the arrangement of the bearings during installation, the distance between the bearings, the material of the shaft and the bearing seat, and can be determined according to the working conditions. For spherical roller bearings with high load and high speed, when adjusting the clearance, the influence of temperature rise on the axial clearance must be considered, and the clearance reduction caused by temperature rise must be estimated, that is to say, the axial clearance The gap should be adjusted appropriately larger. For low-speed and vibration-bearing bearings, clearance-free installation or preload installation should be applied. Its purpose is to make the rollers and raceways of spherical roller bearings have good contact, distribute the load evenly, and prevent the rollers and raceways from being damaged by vibration and impact. After adjustment, check the size of the axial clearance with a dial gauge. The method is to fix the dial indicator on the fuselage or the bearing seat first, make the contact of the dial indicator withstand the smooth surface of the shaft, and push the shaft left and right along the axial direction. The maximum swing of the pointer is the axial clearance value.
Thrust self-aligning roller bearings are used to bear axial and radial combined loads with the main axial load, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has a lower friction coefficient, higher speed and self-aligning performance. Thrust 
cylindrical roller bearings and thrust roller bearings are suitable for low-speed applications, and the speed of thrust tapered roller bearings is slightly higher than that of thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings, which can only bear one-way axial load and slight impact, and can limit the axial displacement of the shaft (or shell) in one direction, so they can be used for one-way axial positioning. But its carrying capacity is far greater than that of thrust ball bearings. When the rollers are rolling, due to the different linear speeds at both ends of the rollers, the rollers inevitably slide on the raceway of the ring. Therefore, the limit speed of this type of bearing is lower than that of thrust ball bearings, and it is usually only suitable for low-speed operation occasions. Thrust cylindrical roller bearings of standard design adopt lathe-made metal solid cages, and cages of other types or materials can also be used according to user requirements. Thrust tapered roller bearings can only bear one-way axial load and can limit the one-way axial displacement of the bearing, so they can be used for one-way axial positioning. Compared with thrust cylindrical roller bearings, it has larger load capacity and smaller relative slip, but lower limit speed.
