(54) РАБОЧЕЕ КОЛЕСО ОСЕВОГО ВЕНТИЛЯТОРА(54) WORKING WHEEL AXIAL FAN

1one

Изобретение относитс  к области вентил торостроени .This invention relates to the field of torus construction.

Известны рабочие колеса осевых вентил торов с поворотными лопатками, оси которых установлены в аксиальных шариковых подшипниках и закреплены в ступице.Known impellers of axial fans with rotary vanes, the axes of which are installed in axial ball bearings and fixed in the hub.

С целью снижени  напр жени  в предлагаемом устройстве комлева  часть каждой лопат ки выполнена в виде корпуса подшипника с крышкой, и ось лопатки снабжена дисковым фланцем, солр женным одной стороной с внутренней поверхностью корпуса через пружинную шайбу, другой - с неподвижной обоймой подшипника, а врашаюша с  обойма размешена на опорном кольце, установленном на крышке корпуса, и поверхности сопр жени  кольца и обоймы выполнены коническими.In order to reduce the voltage in the proposed device, the left part of each blade is made in the form of a bearing housing with a lid, and the blade axis is provided with a disk flange, one side of the blade with the inner surface of the body through a spring washer, the other with a fixed bearing housing, and the yoke is placed on the support ring mounted on the housing cover, and the mating surfaces of the ring and yoke are made conical.

На фиг. 1 показано предлагаемое рабочее колесо осевого вентил тора с частичным продольным разрезом; на фиг. 2 - продольный разрез лопатки рабочего колеса с установочными элементами.FIG. 1 shows the proposed impeller of an axial fan with a partial longitudinal section; in fig. 2 is a longitudinal section of the impeller blade with mounting elements.

Рабочее колесо осевого вентил тора содержит поворотные лопатки I, оси 2 которых установлены в аксиальных шаршковых подшиппиках и закреплены в ступице 3 с помошью крепежных элементов -1. Комлева  часть каждой лопатки 1 выполнена в виде корпуса 5 подшипника с крышкой 6.The axial fan impeller contains rotary vanes I, whose axes 2 are installed in axial ball bearings and are fixed in the hub 3 with the aid of fasteners -1. Butt part of each blade 1 is made in the form of a bearing housing 5 with a cover 6.

Ось 2 лопатки 1 снабжена дпсковым фланцем 7, сопр женным одной стороной с внутренней поверхностью корпуса 5 через пружинную шайбу 8, а другой - с неподвижной обоймой 9 подшипника.The axis 2 of the blade 1 is provided with a flanged flange 7, which is joined to one side with the inner surface of the housing 5 via a spring washer 8, and the other side with a fixed holder 9 of the bearing.

Врашаюша с  обойма 10 размеш,епа на опорном кольце 11, установленном на крышке 6 корпуса 5.Vrashayusha with the holder 10 is placed, on the support ring 11 mounted on the cover 6 of the housing 5.

Поверхности сонр жени  опорного кольца 11 и обоймы 10 выполнены коническими.The surfaces of the carriage of the support ring 11 and the yoke 10 are conical.

Предмет изобретени Subject invention

Рабочее колесо осевого вентил тора с поворотными лопатками, осп которых установлены в аксиальных шариковых подппшниках и закреплены в ступице, о т л и ч а ю ш е е с   тем, что, с целью снижени  напр жений, комлева  часть каждой лопатки выполнена в виде корпуса подшипника с крышкой, п ось лопатки снабжена дисковым фланцем, сопр жепным одной стороной с внутренней поверхностью корпуса через пружинную шайбу, другой - с неподвижной обоймой подшипника, а вран1аю3 ща с  обойма размещена на опорном кольце, установленном на крышке корпуса, и поверх4 ностн сопр жени  кольца и обоймы вьтолнены коническими.The impeller of an axial fan with rotary vanes, the smallpox of which is installed in axial ball bearing pockets and fixed in the hub, is so that, in order to reduce the stresses, the butt part of each blade is made in the form of a housing bearing with a lid, the blade axis is provided with a disk flange, matching one side with the inner surface of the body through a spring washer, the other with a fixed bearing sleeve, and lying with the holder mounted on the support ring mounted on the body cover and over the top4 The interface between the ring and the holder is made conical.
