IMPROVED ANTI PRICTION BEARING FOR FLOAT MUUNTING NOSE PIN OF ROCKER ARM OF CIRCULAR LOOM AND THE LIKE.

Abstract

Anti-friction bearing for float mounting nose pin of rocker arO of circular loom and the like comprising a roller bush/ball bearing having an oversized central bors hole, each side thereof being provided with a tepered ring, antj said central bore hale foreing a seat far float mounting nose pin of a rocker arm and outer, periphery of said bush/bail bearing being provided a pair of convex shaped shoulders separated by a half-parabolic concave grooved ring for providing two line bearing surface contacts between corresponding bearing surfaces optionally outer periphery of said bush/ban bearing being provided with a half parabolic convex projection for providing a singlB line pe contact betwen corresponding surfaces farmed hy upper and lower waxi surfaces of respective serpentine grooved passages provided on outer wall surface of a rotatably mounted hollow cam sheft/drum fitted sheft of a circular loom in which said bush/ball hearing together with said nose pin being adapted to freshly roll within said bearing surfaces while said nose pin being adapted to be pushed upwardly and downwardly during each rotation of said hollow cam sheft/drum and said nose pin being float mounted within said over-sized central bore hole provides annular passage between said nose pin and inner periphery of said central bore hole for free flow of lubricating oil therethrough while rocking said nose pin within said Bnnular passage during respective upward and downward stooke of said nose pin within respective grooved passages in said hollow oam shaft/drum.
