Abstract

"MECANISMO DE POSICIONAMENTO DE ACIONAMENTO E MECANISMO DE AJUSTE DE JOGO". Um mecanismo de posicionar acionamento com ajuste de jogo para uso num difusor de tubo variável para um compressor centrífugo. Um meio de acionamento rotativo está preso fixadamente na carcaça de um compressor centrífugo com uma engrenagem de pinhão montada na mesma. Uma engrenagem de cremalheira está montada no anel interno e adaptada para engatar em disposição conjugável a engrenagem de pinhão. O meio de acionamento rotativo é operável para posicionar o anel interno entre uma posição totalmente aberta e uma posição parcialmente fechada. é provido um limitador de curso para limitar positivamente o curso do anel interno nas posições totalmente aberta e parcialmente fechada. O mecanismo de ajuste de jogo é constituído por uma carcaça que possui um corpo cilíndrico posicionado concentricamente em torno de uma primeira linha central e que possui um furo disposto axialmente através do corpo posicionado em torno de uma segunda linha central. A árvore de acionamento está disposta rotativamente concêntrica à segunda linha central dentro do furo. O anel interno está posicionado de tal modo que engraze a engrenagem de cremalheira. A carcaça está disposta dentro da caixa e é operável rotativamente para efetuar um ajuste do jogo entre a engrenagem de pinhão e a engrenagem de cremalheira."DRIVE POSITIONING MECHANISM AND GAME ADJUSTMENT MECHANISM". A drive positioning mechanism with game adjustment for use in a variable tube diffuser for a centrifugal compressor. A rotary drive means is fixedly attached to the housing of a centrifugal compressor with a pinion gear mounted thereon. A rack gear is mounted on the inner ring and adapted to engage the pinion gear in a configurable arrangement. The rotary drive means is operable to position the inner ring between a fully open position and a partially closed position. a travel limiter is provided to positively limit the travel of the inner ring in the fully open and partially closed positions. The game adjustment mechanism consists of a housing that has a cylindrical body positioned concentrically around a first central line and that has a hole disposed axially through the body positioned around a second central line. The drive shaft is arranged rotationally concentric to the second center line inside the hole. The inner ring is positioned in such a way that it makes the rack gear funny. The housing is arranged inside the box and is rotatable to adjust the game between the pinion gear and the rack gear.
