Problems solved by technology

However, the wall surface of the cooling water package is in sliding contact with the spindle, and the contact thermal resistance is relatively large, so the cooling effect is limited
[0003] In the Chinese utility model patent with the application number CN201120223303.1, by setting the cooling medium in direct contact with the main shaft, the flowing cooling medium directly flows through the surface of the main shaft to achieve cooling of the main shaft, but the heat exchange area between the cooling medium and the main shaft is limited. The thermal effect needs to be further strengthened

Abstract

The invention discloses a pulsating flow enhanced cooling bearing seat device. The pulsating flow enhanced cooling bearing seat device includes a sealing ring, a bearing end cover, a gasket, an integral bearing seat, a bearing and a shaft sleeve. The integral bearing seat The two ends are respectively sleeved on the main shaft through bearings. The bearing is provided with a shaft sleeve near the inner side of the integral bearing seat. The seal between the cover and the main shaft is sealed by a sealing ring, and the gasket is arranged between the integral bearing seat and the bearing end cover; the sleeve with spiral ribs is mirror-symmetrically connected to the main shaft, and the two sides of the cooling water tank The end is provided with an interface, and the interface is connected to the integral bearing seat through a ferrule joint and a pipeline; the cavity is filled with cooling medium, and the middle lower surface of the integral bearing seat is provided with a cooling medium outlet . The beneficial effect is: it has the characteristics of simple structure, high cooling and heat exchange efficiency, convenient installation and maintenance, and no need for additional power source.

Description

technical field [0001] The invention relates to the technical field of bearing seat and shaft cooling, in particular to a pulsating flow enhanced cooling bearing seat device suitable for high-temperature fans. Background technique [0002] Centrifugal fans are a common gas conveying device widely used in various industries. Inside the centrifugal fan, the mechanical energy of the impeller is converted into the kinetic energy of conveying gas, and outside the centrifugal fan, the motor inputs the shaft power into the centrifugal fan through the transmission device. The transmission device includes the main shaft, bearing housing, rolling bearing and coupling. For high-temperature centrifugal fans, the heat of the high-temperature gas conveyed is transferred to the bearing and generator rotor through the impeller and main shaft. If no effective measures are taken, the temperature of the bearing and generator rotor will be too high, which will affect the normal operation and w...
