OIL SCRATCHER DEVICE IN VERTICAL THURST BEARING

摘要

PURPOSE:To enable an oil scratcher plate to be slidably contacted with the lower surface of the thrust collar even if the supporting column is inclined in a counter-rotational direction by a method wherein the supporting groove at the upper part of the supporting column of the coil scratcher plate is formed having a wide up-faced V-form. CONSTITUTION:The upper part of the supporting column 31 is provided with a V-shaped supporting groove 31a having an upper side portion. An opening degree of the supporting groove 31a is set such a degree as one in which the oil scratcher plate 14 is not inclined in a counter-rotational direction in view of the accuracy of machining of the supporting groove 31a to be expected or fixing and machining errors of the supporting column 31 for the fixing plate. Further, the bottom part of the supporting groove 31a is provided with a hole for spring 31b, the compression spring 15 is set in the hole and thereby the oil scratcher plate 14 is pushed up to enable a pushing-up and sliding of the oil scratcher plate 14 against the lower surface of the thrust collar 3.
