Abstract

FIELD: mechanical engineering. SUBSTANCE: unit has races, rolling bodies, and openings for receiving fastening members for joining with the machine frame. The openings are spaced at a distance of three-four diameters of the rolling bodies. The height of the races is 2.5-2.9 of the diameter. EFFECT: enhanced longevity. 1 dwg

Description

Изобретение относится к машиностроению, в частности к опорно-поворотным устройствам (ОПУ) строительных и грузоподъемных машин. The invention relates to mechanical engineering, in particular to slewing rotary devices (OPU) of construction and lifting machines.

Известно ОПУ, содержащее обоймы, тела качения и отверстия под крепежные элементы для соединения с рамами машин. Known OPU containing clips, rolling elements and holes for fasteners for connection with the frames of machines.

Определение числа упомянутых отверстий расчетным путем не приводит к обеспечению оптимальных параметров характеристик ОПУ. The determination of the number of the mentioned holes by calculation does not lead to the provision of optimal parameters for the characteristics of the OPU.

Технический результат изобретения состоит в обеспечении при минимальных затратах металла максимальных несущей способности и долговечности ОПУ. The technical result of the invention is to provide at minimum metal cost maximum bearing capacity and durability of the OPU.

Это достигается тем, что в ОПУ, содержащем обоймы, тела качения и отверстия под крепежные элементы для соединения с рамами машин, упомянутые отверстия размещены с шагом, равным трем-четырем диаметрам тел качения, а высота обойм составляет 2,5-2,9 этого диаметра. This is achieved by the fact that in an OPU containing cages, rolling elements and holes for fasteners for connecting to the frames of the machines, said openings are placed in increments of three to four diameters of the rolling elements, and the height of the clips is 2.5-2.9 of this diameter.

На чертеже представлено ОПУ. The drawing shows the OPU.

Опорно-поворотное устройство содержит обоймы 1 и 2, тела качения ролики 3 и отверстия 4 под крепежные элементы для соединения с рамами машин. The rotary support device includes clips 1 and 2, rolling elements rollers 3 and holes 4 for fasteners for connection with the frames of the machines.

Отверстия 4 расположены с шагом t(3-4)dp, где dp диаметр роликов.The holes 4 are arranged in increments of t (3-4) d p , where d p is the diameter of the rollers.

Высота h0 обойм 1 и 2 составляет (2,5-2,9)dp.The height h 0 of clips 1 and 2 is (2.5-2.9) d p .

Такое выполнение устройство позволяет при минимальных затратах металла получить ОПУ высокой работоспособности, т.е. максимальной несущей способности и долговечности. This embodiment of the device allows for minimal metal costs to obtain an OPU of high performance, i.e. maximum bearing capacity and durability.
