Spiral roller bearings are a type of rolling bearings. Their rolling system uses spiral rollers wound with steel belts, hence the name. It has the following main features and uses:
Features:
1. Large load-bearing capacity: Spiral roller bearings can withstand large impact radial loads and axial loads. This is because the rollers are spiral. When bearing radial loads, the rollers roll obliquely along the raceway. , so that each roller only bears one radial force. When bearing axial load, the inclination angle of the rollers will become smaller, and the force endured by each roller will become larger, so it can withstand larger axial loads.
2. Good elasticity and large clearance: Due to the use of spiral rollers wound with steel belts, this bearing has large elasticity and radial clearance, which helps to withstand impact loads.
3. Low friction and long life: The roller design of spiral roller bearings enables it to maintain low thermal deformation during high-speed operation, thus having high fatigue resistance and life.
4. Limited accuracy: Due to the elastic deformation of spiral roller bearings, their working accuracy cannot be fully guaranteed, so their accuracy level is usually only ordinary level, and there is no higher precision level.
use:
Due to the above characteristics, spiral roller bearings are mostly suitable for components that do not require high rotation accuracy but often bear large impact loads. For example, it is often used in heavy-duty equipment such as engineering machinery and construction machinery, as well as in environments that need to withstand high loads and vibrations, such as large steel plants. In these situations, spiral roller bearings can exert their excellent load-bearing capacity and impact resistance to ensure the stable operation of the equipment.
Spiral roller bearings, with their unique structural design and superior performance, play an important role under working conditions of heavy load, vibration and shock load. However, its limited accuracy also determines the limitations of its scope of application. When choosing to use spiral roller bearings, comprehensive considerations need to be made based on specific working conditions and requirements.
