Vibrating screen rolling bearing in the work process by the impact of the load brought about by the larger, from the eccentric high-speed rotation of centrifugal force and centrifugal acceleration is also *er, coupled with more dust in the working environment, so the type of bearing, speed limit , Mounting with the size, clearance, self-lubricating properties and other requirements are higher, ordinary bearings in this bad working conditions are easy to damage. If the bearing design is not properly selected at the beginning of the design, the bearing life will be shorter.
Approach:
Use special bearings for vibrating screens. The commonly used shaker bearings generally have two types of cylindrical roller bearings and self-aligning roller bearings. Cylindrical roller bearings have a large radial load carrying capacity, are also subject to high speed limits, and have a high load carrying capacity for dynamic and static loads, but require a high degree of coaxiality for bearing housing bores.
Spherical roller bearings not only have a large radial load capacity, but also can withstand axial load in any direction, good centering *, can compensate for the different shaft problems caused by the bearing seat hole processing, but can not bear pure axial Load.
Due to the harsh environment in which the vibrating screen is used, many bearing manufacturers produce special large clearance bearings for vibrating screens. The bearing materials are made of special materials, and the structure is more different than ordinary bearings. It has strong bearing capacity, good impact resistance, and good lubrication *. Good features.
