With a total of 5 patents to his name, Maiwa's work exemplifies innovation and practical application in technology.

Latest Patents

One of Maiwa's latest inventions is a rolling bearing that utilizes a porous rolling element impregnated with a selected lubricant. This design allows the bearing to function effectively in various conditions without discharging foreign objects, while also minimizing dust generation and extending its lifespan. The rolling bearing consists of an outer ring, an inner ring, and multiple rolling elements assembled between the opposing track surfaces of the rings. The combination of a porous rolling element and a non-porous rolling element enhances its performance.

Another significant patent is the double-row angular contact ball bearing designed specifically for CT scanning devices. This innovative bearing features an inner member with a pair of raceway rings that include positioning holes for a positioning member. This design effectively suppresses radial decentering of the raceway rings. The raceway rings are fastened together using fixing bolts, ensuring that the end surfaces are in abutment to apply a preload at a fixed position between the balls and raceway surfaces. The relationship defined by Db/h ≤ 0.26, where Db is the diameter of each ball and h is the radial dimension from the center of each ball to the inner diameter of the inner member, is crucial for its functionality.
