Title: Masatoshi Niina: Innovator in Needle Roller Bearing Technology
Introduction
Masatoshi Niina is a prominent inventor based in Iwata, Japan. He has made significant contributions to the field of bearing technology, holding a total of 4 patents. His innovative approaches have led to advancements in manufacturing processes and product design.
Latest Patents
One of his latest patents is a method of manufacturing a shell type needle roller bearing, which includes drawing and ironing operations. This method involves forming a shell type outer ring through a pressing combined with an ironing step. The lubricating conditions during this ironing step are maintained in a substantially fluid lubricating state. This approach helps to restrict the circumferential surface roughness of the inner-diameter surface, the inner-diameter roundness, and the amount of uneven thickness of the tubular portion to predetermined value ranges. As a result, the life of the shell type needle roller bearing is prolonged, and the acoustic level during use is lowered.
Another notable patent is for a rocking bearing that is designed to be low in cost. In this design, a raceway is formed on the inner periphery of an arcuate bearing ring. Rolling elements are received in pockets of a retainer that is positioned opposite to the raceway. The bearing ring is created by pressing a steel plate, which reduces costs while achieving light weight and compactness.
