Overview of tapered roller bearings
Tapered roller bearing is a kind of separation type rolling bearing. Its core design feature is that the roller and raceway are tapered, and the extension line meets at a point on the bearing axis. This unique design allows it to withstand both large radial loads and axial loads (usually unidirectional). Due to its excellent load capacity and rigidity, it plays a crucial role in numerous fields such as automotive, machine tools, and construction machinery.
Features of tapered roller bearings
1.Separability: The inner and outer ring components can be installed separately, which greatly facilitates installation, disassembly and post-maintenance.
2.Cone Angle: The cone Angle of the inner and outer ring raceway determines the ability of the bearing to bear the axial load. The larger the cone Angle, the stronger the ability to withstand the axial load.
Working principle of tapered roller bearings
The "tapered" design of tapered roller bearings is the essence of its function. Since the intersection of the raceway surface extension lines is located on the axis of the bearing, the roller can achieve pure rolling on the raceway. When subjected to radial load, an axial component force is generated, so tapered roller bearings usually need to be mounted in pairs to counteract this internal axial force and to withstand the axial load in both directions.
Application scenarios of tapered roller bearings
1.Car:
Wheel hub: This is one of its most classic applications, the front wheel hub unit of modern cars often uses paired tapered roller bearings.
Gearbox, differential, main reducer.
2.Machine tool: spindle, lead screw support and other parts that need high rigidity and precision.
3.Construction machinery: excavator, loader walking mechanism, rotary support, etc.
4.Metallurgical mine: rolling mill, crusher and other heavy equipment.
5.Wind turbine gearbox: need to bear huge dynamic load.
Installation and Adjustment (critical step) of tapered roller bearings
1.Clearance and pretension: this is the core technology of tapered roller bearing application.
Clearance: refers to the small clearance existing inside the bearing. Proper clearance is necessary to ensure lubrication and avoid excessive temperature rise.
Pretension: an axial force is applied during installation to generate negative clearance inside the bearing. Preloading can improve rigidity and rotation accuracy, but it will increase friction temperature rise and reduce life. It must be controlled precisely.
2.Pair installation:
Back to back (O-shaped arrangement) : provides strong torque rigidity, can effectively resist bending deformation of the shaft.
Face to face (X arrangement) : Better adaptability to thermal elongation of the shaft.
Series (T-shaped arrangement) : Used to withstand maximum axial load in a single direction.
