The structure of double row tapered roller bearings includes an outer ring, two inner rings, spacers and rolling elements. The characteristic of this kind of bearing is that it can withstand large radial loads, mainly radial and axial combined loads and moment loads, and is mainly used in components that limit the two-way axial displacement of the shaft and housing. In addition, the clearance and pre-interference of double-row tapered roller bearings can be adjusted by changing the thickness of the spacer ring.
The structure of double row tapered roller bearings includes outer rings, inner rings, rolling elements and cages. Its characteristics include the following aspects:
1. Loading capacity: This type of bearing can not only bear radial load, but also bear bidirectional axial load. Therefore, they are suitable for applications where multiple loads must be sustained simultaneously.
2. Adjust the clearance: There is a spacer ring between the two inner rings or the outer rings of the double-row tapered roller bearing. By changing the thickness of the inner and outer spacer rings, the clearance of the bearing can be adjusted.
3. Limit axial displacement: The bearing can limit the axial displacement of the shaft or box on both sides within the axial clearance limit of the bearing, ensuring the stable operation of the machine.
4. Wide range of applications: Double row tapered roller bearings are widely used in machine tools, reducers, automobiles, agricultural machinery, mining, metallurgy, plastic machinery, heavy machinery and other industries.
The use and installation of double-row tapered roller bearings also need to be selected and adjusted according to the specific working environment and needs to achieve the best use results.
