Description
Изобретение относитс к области подъемно-транспортных устройств, а именно к винтовым-подъемникам с самоустанавликаюшейс опорной гайкой.The invention relates to the field of hoisting-and-transport devices, namely to screw-lifts with a self-supporting clipping nut.
Известна самоустанавливаюша с опорна гайка подъемника, содержаща корпус с закрепленными на нем стержн ми, гильзу и опорные шайбы со сферической поверхностью (1.The self-adjusting bearing nut of the lift is known, comprising a housing with rods fixed thereto, a sleeve and support washers with a spherical surface (1.
Недостатками этой гайки вл ютс низкий коэффициент полезного действи (к.п.д) винтового соединени и мала его износоустойчивость из-за возникающих значительных поперечных сил, а также дополнительные потери в месте контакта вилок и направл ющих.The disadvantages of this nut are the low efficiency (efficiency) of the screw joint and its low wear resistance due to the significant transverse forces that occur, as well as additional losses at the point of contact of the forks and guides.
Цель изобретени - повыщение к.п.д. винтовой пары путем уменьщени поперечных усилий в последней.The purpose of the invention is to increase the efficiency. screw pair by reducing lateral forces in the latter.
Это достигаетс тем, что на стержн х смонтирован с возможностью возвратнопоступательного перемещени хомут, на котором перпендикул рно стержн м установлены опорные элементы, взаимодействующие с упорами, закрепл емыми на грузовой площадке.This is achieved by the fact that a collar is mounted on the rods with the possibility of reciprocating movement, on which perpendicular to the rods are mounted supporting elements cooperating with stops fixed on the cargo platform.
Такое выполнение устройства позвол ет максимально сократить усили на самоустановку гайки в процессе работы и снизить поперечные силы, действующие в винтовсй паре.Such an embodiment of the device makes it possible to minimize the effort on the self-installation of the nut during operation and to reduce the lateral forces acting in the screw pair.
На фиг. 1 изображена схематически гайка, продольный разрез; на фиг. 2 то же, разрез А-А фиг. 1; на фиг.Зто же, разрез в точке пересечени осей.FIG. 1 shows a schematic of a nut, a longitudinal section; in fig. 2 is the same, section A-A of FIG. one; Figs. The same section in the point of intersection of the axes.
