Abstract

Обойма винта включает часть для крепления лопасти, часть для крепления стойки и промежуточную часть, проходящую между частью для крепления лопасти и частью для крепления стойки. Промежуточная часть, часть для крепления лопасти и часть для крепления стойки ограничивают необязательную внутреннюю кромку, так что внутренняя кромка, если она имеется, ограничивает отверстие. Обойма винта, кроме того, содержит периферийную внешнюю кромку, проходящую вокруг части для крепления лопасти, промежуточной части и части для крепления стойки. По меньшей мере либо внешняя кромка, либо внутренняя кромка, если она имеется, содержит часть с уменьшенной толщиной, толщина которой меньше толщины прилегающей части обоймы винта.
