<p>PURPOSE: To enhance load holding ability and stability in the speed of threshold value by forming in the inner surface, a plurality of pads consisting of a ridge, a root and a crooked surface connecting in between and making the crooked surface to be a form determined by a specific function. CONSTITUTION: A rotor 12 turning counter-clockwise is supported within an inner surface 17, the demarcation of which is to be determined by a plurality of pads 18 consisting of an outer surface in cylindrical shape 16, root 20, ridge 22 and curve 24 which connects the root and ridge. Each point of the crooked surface is determined from the equation; h=r+s(1-θ1 /θ2 )<α> (Here, h = distance between the axis and the point on the crooked surface; r = radius r1 of the ridge 22 against the axis; s = the difference between the radius r1 and the radius r2 from the axis to the root 20;θ1 = angle between radius r1 and the point on the crooked surface.θ2 = the angle between the radius r1 and r2α= exponent of the curve of the crooked surface). Accordingly, high load holding ability and high stability in the speed of threshold value can be obtained and bearings can be easily produced at a low cost.</p> |
