Latest Patents
Tsuji's latest patents include a thrust ball bearing and a cage for spherical roller bearings. The thrust ball bearing patent aims to reduce the contact surface pressure between the balls and the retainer at slide contact positions. This innovation suppresses the wear of the retainer by increasing the depth of drawing of the inner and outer portions that embrace the balls. The design allows for the balls to slidably contact the retainer at three specific points, thereby minimizing wear compared to prior art.
The cage for spherical roller bearings features a pair of annular bodies connected by columns that receive spherical rollers. Each column has side faces formed by a composite surface, which includes a flat surface outside the pitch circle and a conical surface inside it. This design ensures that the flat surfaces come into point-to-point contact with the spherical rollers during rotation, enhancing the overall efficiency of the bearing.
