Tapered roller bearings are separable bearings, bearing inner and outer rings with tapered raceways line. These bearings are mounted on roller rows into single row, double row and four row tapered roller bearings, such as different structural types. Single row tapered roller bearings can bear radial load and axial load in one direction. When the bearing radial load

In machining
In machining, often encounter two typical rotary body parts: one is the linear rotary body parts, one is the rotary part curved cylindrical machined parts required when due to wall alignment, and two kinds of parts the wall can not be processed, it is difficult to ensure uniform thickness, thus giving great difficulty to find positive workpiece. Therefore, we use multi-table to find positive ways to solve this problem.
In machining, often encounter two typical rotary body parts: one is the linear rotary part (there are many parts evenly distributed on the inner wall of the stairs), one is curved rotary part. As required when machining parts with cylindrical inner alignment, and two kinds of parts of the wall can not be processed, it is difficult to ensure uniform thickness, thus giving great difficulty to find positive workpiece. Since the rough shape of the inner wall of irregular and complex designs cam is very difficult to achieve the required accuracy is not easy, so we use a multi-table to find positive ways to solve this problem.slewing bearing system architecture and design CAD system brings together the database technology, knowledge base technology, computing and reasoning techniques, finite element analysis techniques and parametric drawing technology. The system consists of expert system design, finite element analysis and parametric drawing three parts. Both between the various parts combination, collaboration, and functional independence, each module can be used alone as a subsystem through the system function of each module framework will combine to satisfy the needs of users
