Bearings of tapered roller bearings can be divided into different structural types such as single row, double row or four row tapered roller bearings according to the number of rows of rollers. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, an axial component will be generated, which requires another bearing that can withstand the axial force in the opposite direction to balance. The most widely used tapered roller bearings are single row tapered roller bearings. Smaller double row tapered roller bearings are used in the front wheel of the car. Four row tapered roller bearings are generally used in large cold and hot. In large machines such as rolling mills.
Tapered roller bearings - installation
The tapered roller bearings of various models and structures are similar in installation. The small series is introduced for the installation of four-row tapered roller bearings. Firstly, the tapered roller bearings are first loaded into the bearing housing, and then The bearing housing is fitted into the journal. When the outer ring of the four-row tapered roller bearing is mounted with the bearing housing, the dynamic form is also used to fit the outer ring A into the bearing housing. The tapered roller bearing is printed with the character symbol on the outer ring, the inner ring and the inner and outer spacers at the time of shipment. The installation must be carried out in order according to the order of the character symbols. After installation, all parts are placed in the bearing housing, and then the axial direction between the inner ring and the inner spacer, the outer ring and the outer spacer are abutted.
Tapered roller bearings - Application
The bearing bearing force of the tapered roller bearing depends on the raceway angle of the outer ring, and the angle determines the bearing strength of the tapered roller bearing. The number of rows of rolling elements in a bearing is divided into single row, double row, and four row tapered roller bearings. The travel of the single-row tapered roller bearing needs to be adjusted by the user during use. The double-row and four-row tapered roller bearing clearances are manufactured according to the requirements of the user when the product leaves the factory, and no user adjustment is required. Tapered roller bearings are mainly used in industries such as automobiles, mining, metallurgy, plastic machinery, and tie machines.
