Abstract

"MECANISMO DE TRAVAMENTO PARA UM ELEMENTO DE TRABALHO". Um anel operacional (7) é ajustado externamente com a possibilidade de girar ao corpo principal da porca de travamento entre um flange de travamento (3) e um flange da porca de travamento (5); mancais de esferas (11) são inseridos entre o anel operacional e o flange de travamento; três ou mais sulcos em forma de arco (54) são formados - voltados no sentido uns dos outros e se estendendo em formas concêntricas na direção circunferencial - nas superfícies de encontro do flange da porca de travamento e do anel operacional; esferas de travamento (9) são acomodadas dentro dos sulcos em forma de arco do flange da porca de travamento (5) e do anel operacional voltados uns para os outros; a dimensão total - na direção axial do eixo de acionamento rotativo - de cada par de sulcos em forma de arco que acomodam as esferas de travamento (9) é estabelecida menor que o diâmetro de uma esfera de travamento; e um denteamento localizado é formado nas superfícies do fundo sobre no mínimo um lado de ditos pares de sulcos em forma de arco."LOCKING MECHANISM FOR A WORKING ELEMENT". An operational ring (7) is adjusted externally with the possibility of rotating the main body of the lock nut between a locking flange (3) and a locking nut flange (5); ball bearings (11) are inserted between the operating ring and the locking flange; three or more arc-shaped grooves (54) are formed - facing each other and extending in concentric shapes in the circumferential direction - on the surfaces meeting the flange of the locknut and the operating ring; locking balls (9) are accommodated within the arc-shaped grooves of the locking nut flange (5) and the operating ring facing each other; the total dimension - in the axial direction of the rotary drive shaft - of each pair of arc-shaped grooves that accommodate the locking balls (9) is established less than the diameter of a locking ball; and a localized indentation is formed on the bottom surfaces on at least one side of said pairs of arc-shaped grooves.
