Abstract

Опора постоянного усилия, содержащая корпус, шток с пружиной, отличающаяся тем, что шток выполнен ступенчатым, нижняя часть прямоугольного сечения верхней ступени большего диаметра размещена в ответном отверстии опорной плиты корпуса опоры, выше нижней части прямоугольного сечения выполнена самотормозящаяся наружная резьба, на которую навернута колпачковая гайка, в торце которой выполнено прямоугольное сквозное отверстие для прохода хвостовика прямоугольного сечения винта, резьбовой конец с несамотормозящейся резьбой которого выполнен в нижней части хвостовика, резьбовой конец винта ввернут в резьбовое отверстие, выполненное с верхнего торца верхней ступени большего диаметра штока, при этом колпачковая гайка своей наружной цилиндрической поверхностью перемещается по внутренней цилиндрической поверхности корпуса опоры, а пружина расположена между опорной плитой корпуса и нижним торцом колпачковой гайки, причем шаги самотормозящейся и несамотормозящейся резьбы равны друг другу, а на нижней ступени меньшего диаметра штока выполнена резьба.Constant-force support comprising a housing, a rod with a spring, characterized in that the rod is stepped, the lower part of a rectangular section of the upper step of a larger diameter is placed in the counter-opening of the support plate of the support housing, a self-braking external thread is made above which the cap screw is screwed a nut in the end of which a rectangular through hole is made for the passage of a shank of a rectangular cross-section of a screw, the threaded end of which has a non-self-locking thread flax at the bottom of the shank, the threaded end of the screw is screwed into the threaded hole made from the upper end of the upper stage of the larger diameter of the rod, while the cap nut with its outer cylindrical surface moves along the inner cylindrical surface of the support housing, and the spring is located between the base plate of the housing and the lower end a cap nut, and the steps of the self-braking and non-self-braking threads are equal to each other, and a thread is made on the lower step of a smaller stem diameter.
