<p>PURPOSE:To obtain a slide rule useful for the sales man of a bearing material, or a designer at a user side, by constituting the slide rule so that bearing surface pressure is graduated in a logarithm on the first sliding scale, and a sliding velocity, a PV value, and the life time of various kinds of bearing materials are graduated in the logarithm on the second sliding scale. CONSTITUTION:The titled slide rule is equipped with a fixed cursor 2 having the first, the second, and the third parts fixed on a substrate, the first sliding scale 4 loaded slidably freely between the first and the second parts, and an indication cursor line 3a. And it includes an indication cursor 3 fixed on the first sliding scale 4, the second sliding scale 5 loaded slidably freely between the second and the third parts, and a fixed scale positioned at the opposite side of the second sliding scale 5 interpos ing the third part of the fixed scale 2, and the fixed scale 2 is equipped with a fixed cursor line 2a at its left end. Also, the bearing surface pressure is graduated in the logarithm on the first sliding scale 4, and the sliding velocity, the PV value, and the life time of the various kinds of bearing materials are graduated in the logarithm on the second sliding scale 5, and a bearing temperature is graduated on the fixed scale, on which the correction factor of the bearing temperature, and bits of informa tion regarding various kinds of bearing materials are described.</p> |
