HYDRAULIC NUT ASSEMBLY AND METHOD OF USE THEREOF |
摘要 |
A hydraulic nut for tensioning an assembly includes a mechanical threaded locking collar to minimize load loss during transfer of hydraulic load to th e locking collar, a 'S' or 'Z' shaped annual piston to minimize height of the hydraulic nut, an annular pressure area to generate an axial load under hydraulic pressure, a hydraulic pressure port and metallic seals to maintain the hydraulic pressure within the annular pressure area that operates in an elastic region and continues to actuate hydraulic pressure after repeated operating temperature cycles. Also disclosed are hydraulic nuts having a 'U' or 'C' shape seal made of a thin rigid material, hydraulic nuts using stub acme threads and a method of using such nuts.
