Abstract

Изобретение относитс  к машиностроению , может быть использовано в приводах подач т желонагруженных станков с ЧПУ, оснащенных шариковыми винтовыми механизмами . Цель изобретени  - повышение долговечности за счет равномерного распределени  нагрузки между всеми витками резьбы. Положительный эффект достигаетс  путем размещени  скосов между третьим и четвертым от наружного торца каждой из гаек 3 витками резьбы. Крышку 5 устанавливают на направл ющие штифты и скос гайки 3 и ст гивают винтами 7, которые прижимают гайку 3 к корпусу 1. Стопорение от про- ворота гаек 3 происходит за счет сил трени  на скосах, 3 ил.The invention relates to mechanical engineering, can be used in drive feeds of toned-loaded CNC machines equipped with ball screw mechanisms. The purpose of the invention is to increase durability by uniformly distributing the load between all threads. A positive effect is achieved by placing bevels between the third and fourth of the outer end of each of the nuts 3 turns of the thread. The cover 5 is mounted on the guide pins and the bevel of the nut 3 and tightened with screws 7, which press the nut 3 to the housing 1. The locking from the spins of the nuts 3 occurs due to the friction forces on the bevel, 3 sludge.
