Description
保持器６の強度を確保する為の簡単な方法としては、この保持器６を構成する１対の素子９、９の厚さを大きくする事が考えられる。但し、この厚さを大きくすると、上記保持器６と他の部材との干渉を起こし易くなり、玉軸受を組み込んだ機械装置の設計が難しくなるだけでなく、上記素子９、９の加工が面倒になり、材料費が増大する事と合わせてコストが嵩む。しかも、素材となる金属板にプレス加工を施して上記各素子９、９を造る際に、折れ曲がり部の加工硬化が著しくなり、逆に強度が低下する場合もある。
本発明の波形プレス保持器は、この様な事情に鑑みて、特に厚さを大きくする事なく十分な強度を確保すべく発明したものである。
As a simple method for ensuring the strength of the cage 6, it is conceivable to increase the thickness of the pair of elements 9 and 9 constituting the cage 6. However, if this thickness is increased, interference between the cage 6 and other members is likely to occur, which not only makes it difficult to design a mechanical device incorporating ball bearings, but also makes processing of the elements 9 and 9 troublesome. As a result, the material cost increases and the cost increases. Moreover, when the metal plate as the material is press-processed to manufacture the above-mentioned elements 9 and 9, the work hardening of the bent portion becomes remarkable, and conversely, the strength may decrease.
In view of such circumstances, the corrugated press cage of the present invention was invented in order to secure sufficient strength without particularly increasing the thickness.
