Abstract
Official abstract text for this publication.
A rolling bearing includes balls made of a shape memory alloy, in particular Nitinol 60, as rolling elements which roll on at least one bearing ring comprising a groove-shaped raceway. The balls contact the raceway with at least 108% osculation.
First claim
Opening claim text (preview).
1 . A rolling bearing comprising: balls made from a shape memory alloy as rolling bodies, at least one bearing ring having a groove-shaped raceway in which the balls roll, and the balls contact the raceway with an osculation of at least 108%. 2 . The rolling bearing according to claim 1 , wherein the balls are produced from a nickel-titanium alloy with a nickel content of greater than 55 wt. %. 3 . The rolling bearing according to claim 2 , wherein the balls contain 60 wt. % nickel and 40 wt. % titanium. 4 . The rolling bearing according to claim 1 , wherein the balls have a surface hardness of greater than 58 HRC. 5 . The rolling bearing according to claim 1 , wherein the balls have a modulus of elasticity of at most 120 GPa. 6 . The rolling bearing according to claim 1 , wherein a modulus of elasticity of the balls is less than 60% of a modulus of elasticity of the at least one bearing ring. 7 . The rolling bearing according to claim 1 , wherein there are two of the bearing rings, and the bearing rings are made from a stainless steel. 8 . The rolling bearing according to claim 1 , wherein the balls contact one of the bearing rings that is constructed as an outer ring with a different osculation than a second one of the bearing rings that is constructed as an inner ring. 9 . The rolling bearing according to claim 8 , wherein osculation on the outer ring is at least 110%. 10 . A method for using the rolling bearing according to claim 1 , comprising using water as a lubricant for the bearing. 11 . The rolling bearing of claim 7 , wherein the stainless steel is a 1.4108 stainless steel.
