Output shaft cooling and lubricating device for axial flow fan

Abstract

The invention discloses an output shaft cooling and lubricating device for an axial flow fan. The device comprises a cylinder body, wherein a rotating motor is horizontally arranged in the center of the inner part of the cylinder body, fan blades are vertically arranged on one side of the rotating motor, the rotating motor is rotationally connected with the fan blades through a power output shaftin the center of the side wall of the rotating motor, a protective sleeve is arranged around the outer wall of one end, close to the rotating motor, of the power output shaft in a surrounding mode, aspiral copper pipe is arranged around the outer wall of the protective sleeve in a surrounding mode, and protective nets are vertically and fixedly connected to the two sides of the cylinder body. According to the output shaft cooling and lubricating device for the axial flow fan, heat of the protective sleeve is absorbed through cooling liquid in the spiral copper pipe, and a second conical geardrives spiral blades to rotate through a first conical gear so that liquid flowing in the interior can be further achieved; and in addition, a surrounding water pipe is located at an air outlet, the heat can be taken away through flowing air so that cooling of the cooling liquid can be achieved, and meanwhile, a second rotating rod drives a rubber block to rise, and therefore the device has the advantages of efficient cooling and automatic lubrication.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an output shaft cooling and lubricating device of an axial flow fan. Background technique [0002] There are many types of fans. According to the direction of gas flow, they can be divided into centrifugal, axial flow, diagonal flow (mixed flow) and other types. In our daily life and work, axial flow fans are widely used. Axial flow The fan refers to the fan whose airflow direction is the same as that of the fan blade shaft, such as electric fans, air conditioner fans, etc., and is usually used in occasions with high air flow requirements and low pressure requirements. Axial flow fans are mainly composed of fan impeller and machine. Shell composition, simple structure. [0003] Axial flow fans usually place the motor inside the fan cylinder, so that the motor can be cooled to a certain extent during rotation, but due to the blocking of the motor and the fixed component in the cente...
